This paper measures and compares volatility in stock market through use of certain descriptive statistical measures first and then through measures of conditional variance modeled in different ARCH family of frameworks for NIFTY index of 8 Global 500 rank holding companies of India as per 2013 data. Analysis of stock market for the evaluation of risk has received lot of attention both from policy makers and researchers. The quality of risk measures very largely depends on how well the econometric model captures the behavior of underlying asset. We employed GARCH i.e., General Autoregressive Conditional Heteroskedastic (GARCH), models to study the behavior of volatility. Our study shows that GARCH (1, 1) model fairly explains volatility clustering and its high persistence among the selected companies. Key Words: Stock Price, Volatility, Heteroscedasticity, GARCH Model 1. Introduction The Indian capital market especially the stock market has undergone several structural changes over the last 2 decades. The advent of new financial instruments such as Index futures, stock options, and stock futures started in a phased manner from mid 2000. These changes apparently changed the rule of trading and movement in the prices of the stock markets. Theoretical disagreements about coherence in future trading volume and spot trading volume has offset been a matter of consistent argument between practitioners and the theoreticians. Apparently the magnitude of fluctuation in the returns of an asset is directly proportional to the volume of trade and inversely proportional amongst the underlying and derived instrument. Anderson et al 2004 concluded this sampling interday return with sufficient frequency. Assistant Professor. NSHM [email protected] College of Management and Technology, Durgapur, 5 IJNCRDM, Volume 1, Number 1 January-March 2015 It must be noted here that the significance of movement of the assets price is called its volatility. The prediction of volatility in financial market has been rekindled by Bollerslev et al 1994, when they established that financial assets returns volatility are highly predictable. Observably, they realized volatility i.e. measured by simply summing interday squared returns can be treated as “observed volatility”. This has profound implication to financial researchers as it provides better measurement of total risk and can lead to better price prediction of various traded assets. Popular models of volatility clustering where developed by Engle 1982 and Bollerslev 1986. The autoregressive conditional heteroscedastic (ARCH) models was developed by Engle 1982 and generalized ARCH(GARCH) models was developed by Bollerslev 1986 and has been extensively used in capturing volatility clustering in financial time series through the last 2 decades. The advantage of GARCH model is that it can replicate the fat tails observed in many high frequency financial assets return series, where large changes occur more often than a normal distribution could imply. This paper is directed at studying the volatility clustering in Spot and Index of Nifty (S& P CNX Nifty) In order to understand the pattern of clustering in spot market as against the clustering in index. Several studies earlier try to observe and compose the volatility clustering between derivatives prices and the NIFTY. Foremost amongst them are Karmakar (2005) used GARCH (1, 1) model to understand volatility and predictability of NIFTY individual stocks. Rohit Krishnan (2010) observing the large and small error clustering in a GARCH (1, 1) model using restricted stock prices and Index during study period, Dutta (2013) used five minute interval tick prices to compare the volatility clustering in very small period by using asymmetric GARCH and compared the threshold values of GARCH (p, q) and GARCH (1, 1), TGARCH and EGARCH respectively to understand the steadiness of their models in prediction of volatility cluster. Thenmozhi (2002) had examined the impact of nifty futures on the volatility of underlying NIFTY spot index. Gupta (2003) had tried to examine the impact of index futures on the underlying cash market volatility in India and ten compared the futures market volatility with that of spot market. Kumar and Mukhopadhya (2003) have tried to investigate the presence along with the extent of impact of index futures introduction on the volatility structure of the underlying NSE Nifty index. Patra and Mohaptra (2013) studied the compared the volatility between spot and futures market using NSE data base and concluded that the returns in the futures market exhibit lesser volatility than returns in underlying spot market considering GARCH class models which process volatility. 2. Data and Methodology 6 IJNCRDM, Volume 1, Number 1 January-March 2015 High frequency data are direct information from the market and are a recent entrant to the world of statistics. High-frequency data have now become a popular experimental bench for analyzing financial markets (Dacorogna et al., 2001). It cannot be denied that very high frequency data have microstructure effect (e.g., how the data are transmitted and recorded in the data base). In order to avoid serious microstructure biases and at the same time reduce the measurement error due to data generation at low frequency; we have used data at regularly spaced fiveminute intervals (Andersen et al., 2001). The present study uses 8 Global Rank Holding Companies as per 2013 data, listed on NSE over a period of August 2008 to February 2014 days. The closing prices of the day for the companies have become the pointer for study in this paper. The daily return has been calculated using this pointer. The daily closing index of the S&P CNN Nifty has been taken to calculate the return on the index for the same period of time. A large part of the data has been used to model volatility by using the GARCH (1, 1) specification. The data consist of 1401600 data points. 2.1 Volatility forecasting The volatility forecasting represent the accuracy with which one can predict the movement of the stock price/index changes with degree of certainty. For this we go through the following process: Let, r , i 1,..., mt denote log of price relatives at an intra-day time-point i on day t, where mt is the number of return observations obtained by using prices m times per day. Then daily return on day t is calculated as rt i 11 rti m Following Andersen et al, (2001), we define the daily realized volatility ( tV 2 ) as the sum of squares of returns collected at 5-minute intervals: mt Vt rti2 2 i 1 Let t2 denote volatility forecast. One can assess the accuracy of the daily volatility forecasts under a model by considering the simple linear regressions (Andersen et al., 2005) of y t on t2 : yt a b t2 t 7 IJNCRDM, Volume 1, Number 1 January-March 2015 Where yt Vt 2 or rt 2 and then computing the coefficient of determination R 2 . The model with the highest R 2 value may be treated as the best model for predicting y t . On the other hand, if the R 2 Value turns out to be generally higher for one choice of y t , then that choice Vt 2 or rt 2 , may be considered to be a better measure of observed volatility. 3. Objective of the Study: i. ii. iii. iv. To analyze the presence of GARCH (1, 1) in the return series To evaluate the data whether they are normally distributed or not. To examine the presence of autocorrelation in the return series. To comment on the serial correlation of the return series. 4. Methodology: 4.1 Volatility Models Random walk: The random walk model is the simplest of the models considered and it is given 2 2 by r t 1 t , where t is a white noise series. Historical Average: The historical average model (Yu, 2002) is given by: 1 t 1 2 r2 t t 1 i 1 GARCH: The volatility model for the rr or at is said to follow a GARCH (m, s) model (Bollerslev, 1986, Bollerslev et al., 1994) if; at t t , t2 0 i 1 i t2 t j 1 j t2 j , m s (5) Where 0 0, j 0, j 0, max( m. s ) i i ( i t ) 1, with i 0 for i m and B j 0 for j s, And t is a sequence of random variables with mean 0 and variance 1, which is often assumed to have a standard normal or standardized student-t distribution. An exogenous explanatory variable X k may be included in the GARCH model. For example, the GARCH (1,1) model can be augmented as at t t , t2 a0 a1at21 1 t21 1 X kt (6) GARCH (1, 1) process t2 a0 a1at21 1 t21 is done as follows. For this model the meanreverting form is given by (at2 2 ) (a1 1 )(at21 2 ) ut 1ut 1. 8 IJNCRDM, Volume 1, Number 1 January-March 2015 Where 2 a0 /(1 1 1 ) the unconditional long-run is level of volatility and ut (at2 t2 ) is the volatility shock. 5. Results and discussions 5.1 SPOT Market Volatility test The spot market shows that the AIC and SIC criterion are sufficiently low indicating that there is a good case of the fit for the GARCH (1, 1) model. Since the DW value is less than zero, there is autocorrelation in the series. The residual graph indicate that there is a GARCH path where we see upto about 500 days there is high volatility which has gone into a low volatility period after 500 days. The Histograms show a low kurtosis indicating that data are log normal and shows two distinct period of flow of volatility.

Since the p<5%, the null hypothesis is accepted and there is no serial correlation in the series.

The DW value is less than zero indicates that there is positive 10 IJNCRDM, Volume 1, Number 1 January-March 2015 autocorrelation in the data. The low kurtosis being low the data is not necessarily normally distributed. The residual graphs indicate a high volatility period upto 200 hundred days followed by a consistent period of low volatility.

CONCLUSION: There has been an effort made in the paper to map volatility in stock market by comparing the volatility of the spot and the NIFTY in the same period. The paper uses eight distinct companies during the study period and uses GARCH (1, 1) model to understand the clustering patterns. The results shows that there are distinct ARCH and GARCH patterns in the series and the periods are almost similar. The prolonged high volatility period is followed by a long low volatility period. There series are normally distributed and there is autocorrelation in the series. The absence of the serial correlation indicates that the adjacent error terms are related and does not spill into the next period. It is interesting to conclude that the volatility pattern of the spot and index are similar, showing the maturity of the Indian stock market. REFERENCES 1. Alexander M. Mood, Franklin A.

Leadership can be defined as the ability to influence a group towards the achievement of goals or to get the work done from followers without force. To do this successfully, the leader should know him/ her properly and be sure that the vision he/she has is well communicated to the followers. Leadership also demands of building trust among colleagues and trust to leader and taking effective action to realize this leadership potential. Proper aid and support to each other can ensure the achievement of goal and thus in turn, determines the success of a leader. Traversing from the past to present, leadership styles in Indian corporate has been evolved with the change of economic environment and culture which are intertwined. This paper aims to explore specific sustainable leadership qualities and styles which a leader should acquire in this changing environment to steer an organization towards the growth rapidly by motivating and satisfying employees.

INTRODUCTION From mythology to real life, the omnipresence of leaders and their leadership qualities and styles are becoming the subject of interest of modern aspiring youths who love to take the onus to build and shape the future of their working organizations. The relationship between Leadership and Human Resource Management lies in roles and duties assigned to the respective employees and the roles assigned to employee determines the behaviour of that employee and here psychological contracts plays a crucial role in leading the followers and this in turn, determines the labour relations which influence in maintaining harmony and growth of an organization. As per the organization culture and environment, leadership styles are changed accordingly. India, the second largest democratic country and greater degree of diversity, needs a leader who can cope up with different cultures and environments of different provinces. Ab initio, it has been seen that little children fond of hearing the story of mythology or real life where leaders always cast a spell upon their tender minds becoming the centre of attraction of the story. Leaders should have the quality to motivate followers till the goals are achieved or even standing at the verge of fiasco. A leader should be aware of all his/her followers’ abilities, limitations, and intentions so that it would be easier for a leader to guide them. As human resource management, apart from other activities, deals with the development of employees, so leaders can act as catalysts to enhance the ability of employees not only in their assigned jobs but by motivating them and giving moral encouragement. Most of the followers want their leaders should be trustworthy and openly so that they can go forward for the common goal believing that they are guided properly with the hands of dignified individuals. So motivation, trustworthiness, awareness, inspiration and dignified individuality are some traits of leaders which human resource management demands to maximize employee performance to meet employers’ strategic objectives. The concept of corporate leadership is not very age old. Although the term “leadership” is historical associated with eminent leaders worldwide. As change is the only constant, so with the time the world has came across changes and seems to be smaller in terms of communication, cost of communication and mode of transportation and technological advancement made all these things possible and triggers globalization. Amidst of 19 th century, the contemporary process of globalization occurred with the increase of capital and labour mobility across the boundaries coupled with decreased transportation cost. At this, the competition among corporate houses started increasing and the year 2000 onwards, due to 18 IJNCRDM, Volume 1, Number 1 January-March 2015 trade liberalization, these competitions have been triggered worldwide. Due to increased competition, the survival of the corporate became tougher and to cope up with this increased competition, corporate houses felt the need of a person who can set goals by envisaging the future and motivating the employees or followers to achieve that goal maintaining healthy relationship among them. 1.1 . PSYCHOLOGICAL CONTRACTS AND CORPORATE LEADERSHIP At the time of joining employees have to be abiding by rules, regulations and job responsibilities assigned to them by their working organizations. But an informal and invisible obligation is made coupled with mutual beliefs and perceptions between employer and employee. After joining in the organization there arises a relationship which builds expectations to each other i.e. employer and employee. A legal contract never determines how employers or managers or supervisors will behave with their employees or followers. But it has to be assured that there would not arise any false or vague expectations to each other or otherwise on behalf of employees, trade unions generally have to interfere into the tussle between them by the process of collective bargaining and thus a collective agreement is reached. If all the contracts, either visible or invisible, are approved by both the parties then it will be easier for a leader to motivate employees or followers as there will exist a harmonious relationship among the employees. If employees are not happy with the management of their working organization then a tussle will arise among them or among the line and staffs. Then it will be difficult for a leader to guide and motivate them towards the goal which has to be achieved for the sake of their organization and this thing instigates the needs of labour relations which is very crucial for an organization to grow and sustain. 1.2. LABOUR RELATIONS AND CORPORATE LEADERSHIP An interaction between the management and the employees or workers is the key to drive an organization or to make an organization alive. The management of an organization should look after employee benefits in any manner and the management expect the same from its employees. There should be a win-win situation for both the parties for organizational effectiveness and to maintain this situation, labour unions play a vital role. Feelings of labour union and management towards each other determines the behavior of labour union and management. So a leader has to cope up with this attitudinal and behavioural aspects so that he or she can communicate and motivate accordingly. If there would arise any unholy alliance between employees and employers and create grievance to the employees then a true leader, having an aura and veneration, would handle the situation by reducing their grievances and inspire them to give full dedication towards the job and satisfy them by arising a sense of fulfillment. 19 IJNCRDM, Volume 1, Number 1 January-March 2015 2. INDIA AND LEADERSHIP STYLES Post-liberalization period (since 1991) made a history for Indian economy. Experiencing the combination of protectionist, import-substitution and Fabian social democratic-inspired policies which governed sometimes even after the British occupation; India took the breath of economic liberalization that has redirected the country towards the market-based economy. India had established itself as one of the world’s fastest growing economies. In 1991, under the Prime Ministership of P.V.Narasimha Rao, the then Finance Minister Dr. Manmohan Singh adopted liberal and free-market principles and liberalized its economy to international trade. India then started to take part in worldwide movement with capital, goods and services and thus India experienced the concept of globalization regarding which Roland Robertson, a famous sociologist and theorist of globalization, stated in his book Globalization: Social Theory and Global Culture (1992) that globalization is “the compression of the world and the intensification of the consciousness of the world as a whole”. Barriers to international trade have been lowered through the General Agreement on Tariffs and Trade (GATT). So, at the age of globalization, Indian corporate highly feels the need leaders who can guide the organization towards a positive growth in spite of facing huge competition and ample number of obstacles. India is a country of great cultural diversity and multi-religion. The labours, workers or employees of different provinces may have different attitudes, belief systems, behaviours and physical ability towards jobs. A leader should understand all these things. A leader should know the ability of employees, their motives, areas which they lag, way to motivate them, way of effective communication so that he or she can guide and encourage them accordingly towards a predetermined goal keeping mental positivism in each of them at every time and should be assured that for every quantum of time employees are charged, either physically or mentally, and full of enthusiasm. A leader in India should take no autocratic or coercive approach to lead his or her team because not every member of a team are equal in all aspects. If leader takes coercive approach then it may affects negatively because quality of work will fall as employees or workers do not like to work under force or threat. People of different provinces have different psychological patterns and varied level of stamina. So to lead these kinds of people a leader should be liberal by his thoughts of leading and should not strict to a particular leadership style or approach. 3. LITERATURE REVIEW Ample number of studies carried out by various researchers previously all over the world has been gone through as literature review in the area of leadership roles and styles in Human Resource Management. 20 IJNCRDM, Volume 1, Number 1 January-March 2015 Communication: According to Leigh and Maynard (1994), the importance of communication and wrote that hallucination that settle safe and sound inside our head is worthless. If we actually concern about our idea we will crave to allocate it with others. Nearly all successful managers are good communicators and leaders are even better at it. We must refine our communication skills if we want to lead successfully. Sage (2006), Dran (2004), Akerson and MAI (2003), Kohles (2000), West-Burnham (1997), Bennis, Parikh & Lessem (1994), have worked upon the communication as Leadership Role and stated it as great skill. Influence: some scholars think that Influence and supremacy are inextricably linked and influence is the most important concepts in all of leadership. Power is defined as the capacity to cause change. Influence is the degree of actual change in a target person's attitude, values and ethics and this are researched out by the scholars like Clark (1999), Hemlin (2006), McDonald, Michael, Gooding and Cart. (2005), Letendre, Henry and ToIan (2003), Galo. (2001), Musella and Leithwood,(1988), Confidence: Confidence is an essential part for a leader. Jong Ruyter (2006), Kwok et. al. (2000), Bolger, Pulford and Colman (2000), Lambrecht et. al. (1997), Sadler (1970) and investigated on confidence and verify it as leadership role. Strategy: As per Cornelius et. al. (2002), leader must take on certain "roles" to be truly effective. A strategic leadership style can solve issues of long-term importance, including common policies, common direction, and organizational development or enhancement different plans. A good strategic leader can handle easily all issues that will improve the day-to-day running of the business. Priorities: A leader should be able to prioritize the activities and similar was carried out by Fisher (2004), Gibson, Martin and Singer (2004), Gibson, Martin and Singer, 2004), James (2003), Holmes (2002), Yamuna Ako (2002), and Webster (1997). 4. CONCLUSION It is concluded that the leadership is associated with some vital aspects of Human Resource Management, either directly or indirectly and it is evidenced that in most of the organization, irrespective of the industry, leaders are following coercive approach to lead the followers or employees and the employees don’t like this as they are not comfortable to work under force and threat of various forms. Every person has dignity and hardly have they wanted to lose it for anything. If this coercion goes on, the output of any organization will be badly affected. 21 IJNCRDM, Volume 1, Number 1 January-March 2015 5.

Paramita Biswas Abstract Rabindranath Tagore during his life time created a space for himself in literature, culture and other walks of like. He elicited enough encouragement for women and induced in the practice a semblance of management skill for them, by putting them in key areas of managing his university Viswa Bharati. In this paper, Tagore has explored in literature and life to understand his stand how he could manage to do so in a time frame when conservatism was the call of the day. Key Words: Rabindranath Tagore, Women emancipation, management relevance. 1.. Introduction Post 1913, when the first Nobel prize was awarded to Rabindranath Tagore for his lyrical poetry in Bengali “Gitanjali” and for the first time in Asia, it attacted without any qualm the largest attention which was to continue for a while then. This prompted Tagore to pick up issues which required social attention as he was heard and looked after as an ideal both in Bengal and India alike. One the many issues that he addressed during his life time, women emancipation and managing the issues relating to it were one of the major and foremost ideas. Tagor, in his capacity as a poet, philosopher and teacher took upon himself the herculean task of creating a culture which was women centric and which empowered women to a greater extent. His, enablement of women at Viswa Bharati was a case in point. He purported women characters in his literature in a way which not only did give a space for this characters but also provide for a enough space for debating the role of women, the extent of emancipation and the time frame in which they have been frozen. Tagore (1915) in Strisiksa while talking about “The Education of Woman” vouched the opinion that, “Whatever is worth knowing is “Knowledge”. It should be known equally by men and women, not for the sake of practical utility, but for the sake of knowing". Later in the article, he dwelt on this point with clarity. He observed that "Knowledge has two departments: one, pure knowledge; the other, utilitarian knowledge. In the field of pure knowledge, there is no distinction between men and women; distinction exists in the sphere of practical utility; women should acquire pure knowledge for becoming a mature human being, and utilitarian knowledge for becoming true women" Assitant Professor, NCMT,NSHM, Durgapur, [email protected] 23 IJNCRDM, Volume 1, Number 1 January-March 2015 Tagore showed extraordinary support for the emancipation of women and their role in formation of society. His school which was established in Santinikentan and a central theme os development of women and involving them in day to day management of the institution. Majumdar (1976) in her writing and reminiscence of the her stay in Santiniketan clearly observes that she and other women teachers were encouraged to carry out important decision taking at the school and Tagore would stand by them, even though they were not in the requirement of the establishment, which Tagore would modify with the spirit of the decision intact later. It has been observed that the letters of Tagore from Europe, which are completed shows how he drew the differences between European and Indian women. He wrote “they are not confined to the inner chambers of the house. They meet friends. They listen and voice their opinions if there is a discussion among their relations on an elevated subject. They can grasp how intelligent people view a thing from many different angles and many different points of view. So if a topic comes up they don't ask childish questions, nor do they stare in bewilderment. They can hold relaxed conversation with their friends, they are not grim or engulfed in shame at gatherings, they don't get improperly close with their acquaintances, nor are they unsociably distant. They are cheerful and content in society.” ('Letters from an Expatriate in Europe). Tagore was highly influenced by the liberated condition of European women and the education of women in England and entire continent. Tagore(1891), in his Europe Jatrir diary, observes that that women should no longer be imprisoned in the four domestic walls but rather should stand erect and upright for which proper education is required for women also. Tagore not only believed but also practiced women emancipation and education in his life and writings. Throughout his life, Tagore in his writings, always raised voiced against the existing social evils which he believed to be the greatest obstacles in the way of women emancipation and education. 2. Emancipated Women of Tagore’s Household Tagore’s family right from his grandfather Dwarikanath Tagore was liberal and worked towards the emancipation of women. Drawing a counter narrative to the then conservative society, 24 IJNCRDM, Volume 1, Number 1 January-March 2015 female education was given priority from the time of Dwarkanath Tagore. His elder sister Rasibilasi could read Hari Kusum Stabha. Dwarkanath’s wife Digambari Devi showed the courage to cross the threshold of Andar Mahal by attending parties conducted by her husband in the garden house at Belgachia. Tagore’s wife Mrinalini Devi went to Loreto School to improve her English and Kadambari Devi wife of Rabindranath Tagore’s older brother Jyotirindranath was the first women in the clan to ride a horse in the “maidan” defying the then conservative Bengali society. The progressive Jnanadanandini wife of Satyandranath Tagore showed courage and dare to go to England in the 19th century. She was the one who went to Bombay with her husband and left the ancestral house and move to a separate residence with her husband, son and daughter giving birth to the concept of nuclear family. Chitra Deb (1978), in her book ‘Thakur Bariir Andermahal’ meaning the inside story of Tegorian Famaily, says that ‘the modern way of draping the sari with the 'pallu' (end of the drape) thrown around the left shoulder in neat pleats was the result of Jnanadanandini's efforts’. Jnanadanandini’s daughter Indira Devi was the first women graduate of Tagore household. It is obvious that the tremendous cultural richness and progressive cross cultural mentality had been absorbed by Rabindranath, growing within, thus forcing him to go beyond the existing tradition and social condition prevailed in the colonial Bengal. Growing in a family where female education was given priority; provide him with the insight that education is necessity for inner development as well as for the development of the social environment. 3. Women in In Fiction and writings of Tagore Giving equal place to women in his Viswasbharati, Rabindranath proved to be a true advocator of Women emancipation as dreamt by Raja Ram Mohan Roy and Ishwar Chandra Vidya Sagar. Being the champion of women emancipation he purposefully makes women the protagonists of his novels. In question of women emancipation and education he was always with the enlighteners. The analysis of the stories, written specifically in the 20th century, confirms that as far as the question of women in the society is concerned Tagore was never influenced by the patriarchal views. In one of his short story Khata ( Copy or Exercise Book),as the name itself is symbol of education, Tagore focuses on three major issues in the society – child marriage, women education and age difference in marriage. In this story he portrayed age old tradition of our society. Child marriage and women education were two most important issues of 19 th century and naturally he was also influenced and wrote several stories like Khata. As the advancement of women education begins one can notice that the age of marriage of the girls and education qualifications increased with the passage of time in Tagore’s story. 25 IJNCRDM, Volume 1, Number 1 January-March 2015 Education had also given women protagonist the courage, become much stronger to question the established norms of the society. The heroines of the Tagore’s novel which were written in the 1st part of 20th century had their education at home. For example Tagore’s first novel Chokher Bali’s heroine Binodini did not have any formal education but her father appointed a European Governess for his daughter up gradation and grooming. Similarly Suchorita and Lolita of Gora did not have any college education. But Tagore made Suchorita the representative of modern age women who refuse to sit idly at home but to serve the country and the people. Suchorita was the precursor who shows that women too can have political awareness and interest. She surpasses other heroines of Tagore in her keen perception, critical judgment, and liberal outlook. It was Suchorita who made Gora realized that women too have a role in the upliftment of the country. The other character of the novel Gora was Lolita who rebels against all sorts of tyranny and oppression of the society. She was the harbinger of women’s liberation and feminist movement in the 20th century. Bimala, heroine of Ghare Baire (The Home and the World) did not have any formal education but her husband also tried to educate her. Labanya, heroine of Sesher Kabita (Farewell My Friend) written in 1928 was a post graduate and Ela of Char Adhay (Four Chapters) written in 1934 was research scholar. “Rabindranath Tagore’s THE WIFE’S LETTER (Streer Patra) is a powerful feminist writing. This text tried to give a picture of Rabindranath’s perspective of Feminism. The story is a revolutionary one because at a time when the author penned this story, it was impossible to imagine in Indian society that a women was leaving her husband’s home denouncing her marital existence in search of her own identity. 4. Tagore and his women emancipation and Managerial implications in the society From facts to fiction, from life to literature, Tagore throughout his life tried to fight against the ruthless rituals and meaningless dogma in the society. To deviate from the prevailing customs reflected in his text and also in his own life was really path – breaking. As a true follower of Ishwar Chandra Vidya Sagar, Tagore took the initiative to get married his son Rathindranath with Pratima Devi who was a widow. The intellectual, multicultural Tagore’s house hold helped Tagore to evolve as a passionate seeker of freedom, a cosmopolitan man as expressed in his own songs . With this vocal cultivation for the place of women in the society, it has thus become a matter of great debate whether or not, Tagore became the first stepping stone of the creating the batch of women who could take their own decision, walk shoulder to shoulder with her men and share the burden of the family like that of the men in the family. A walk in the “Santinikatan” 26 IJNCRDM, Volume 1, Number 1 January-March 2015 would show even in letter and spirit, how his believe in creating a fearless society for women existed. It is imperative to note that, several women were given official charges during his life time in Viswa Bharati. The ability of women, as depicted in the discussion, shows that Tagore was conscious of the fact that ignoring women would be impossible in the work place as well as in the domestic realm. 5. Conclusion Tagore in his entire life followed his own conscience, campaigning against the existing social evils to rouse social awareness through his writings. He wanted a world where there are no boundaries of religion, caste, and narrow gender politics. Breaking the traditional normative system and questioning the social rituals of Bengal was undoubtedly path breaking. His work and life followed many such instances. It is important to note that Tagore was amongst few at time who would induce women into the mainstream work of the school and university he established and latter even inducted them to several managerial positions within the organization. This showed his ability to create a position for the modern women in the society and make use of the managerial ability. Reference 1. Deb C (1976), Thakur Barier Andar Mahal”, Ananda, p. 126 2.

The study was based on secondary data, from NABARD site. The four sections of the study include total savings of SHGs, total loan disbursed, outstanding loan and non-performing assets. Key Words: Microfinance, outstanding loan, non-performing assets 1. Introduction: Microfinance is the newest silver bullet for poverty alleviation. Wealthy philanthropists like financier George Soros assured millions of dollars in the microcredit movement, banks and MFIs came forward to make the movement successful by lending microfinance funds to the poor. Nobel Laureate Muhammad Yunus, declared microcredit as an important instrument to fight against poverty and United Nations designated 2005 as the International Year of Microcredit. Microcredit has attracted billions of dollars, the “Grameen” banks alone disbursed a huge amount in microloans over the past years, as per the Microcredit Summit Campaign Report 2006, there were 1000 MFIs, and 300 commercial banks in India, that lent an amount of $1.3 billion to 17.5 million people.(Karnani, 2007) Microfinance is the way of providing small loans to the poor families, who lack access to the traditional financial institutions and help them in growing their small business.(Microfinance / Self Help Groups –SHG, n.d.)The need for creating a legal institution that would provide microfinance has been of great importance. The fervour suggests that microfinance should help the poor and achieve the target of poverty eradication, through evaluation. (Satish, 2005) Poverty is multi-dimensional and microfinance played a significant role in providing access to the financial services, and fighting against the impacts of poverty. Phd research scholar, KIIT University, Bhubaneswar, Odisha 29 IJNCRDM, Volume 1, Number 1 January-March 2015 Self Help Groups in India represents a distinctive approach towards financial intermediation that combines access to the low-cost financial services along with the development of women SHG members, through self-management process. SHGs has been given the power to address social issues like abuse of women, dowry system, and schools for children.(Self Help Groups in India A study of the lights and shades, 2006) Self Help Groupis a registered or unregistered small group of 15 to 20 micro entrepreneurs, who have homogeneous background and aspecific purpose where the group members come together to save small amount regularly to meet up their emergency needs and contribute towards a common fund on mutual help basis as the tools of empowerment and social involvement.(Microfinance and self-help groups, n.d.)For facilitating quick and smooth banking service to the poor, National Bank for Agriculture and Rural Development has launched a pilot project, in the year 1991-92, which provided microcredit by linking Self-Help Groups with banks. (Microfinance and self-help groups, n.d.) 2. Review of Literature: In their recent study (Lohana, S.R., Musale, R. S., 2011) discussed about the role of SHGS in micro finance sector, analyzed the status of the Micro finance in India with special reference to SHGs, of different states of India, and forecasted the opportunities available to the SHGS for boosting up the microfinance sector for a period of 2003 to 2005 (Nasir, S., 2013)tried to analyze the prevailing condition of the Microfinance in India, from its beginning till now. The main aim was to discover the gap in functioning of the MFIs and provide practical solution to overcome issues and render financial services by using cost effective techniques.(Vij, D., 2013) attempted to find out the measures for transferring the Self Help Groups into strategic business enterprises, and promote income, and quality of living. (Singh, N.T., 2009)focused on of all the aspects of micro finance in India, especially the institutions that faced the challenges and were involved in promotion, and modes of delivery and rapid developments. (Porkodi, S., Aravazhi, D., 2013) examined the role of micro finance in financial inclusion and the empowerment of people of India(Das, D.K., Boruah, D., 2013)studied the role of Micro-Finance and Self-HelpGroups for the socio-economic development of the poor people in Assam(Behera, A.R., 2010) focused on the SHGs of Odisha that affected the poverty by different approaches and programmes (Ratan, A.L., Chakraborty, S., Chitnis, P.V., Toyama, K., Ooi, K.S., Phiong, M., Koenig, M., 2012) studied about the efficiency and quality gains of the financial record management application built on a low-cost digital slate prototype. (Nair, A., 2005) used a case study approach, to explore the merits and demerits of federating, and suggested some solutions to the problems (Pokhriyal, A.K., Ghildiyal, V., 2011)analyzed the development of microfinance, in terms of contribution, achievements and disappointments of SHG-bank linkage program(Lahkar, R., Pingali, V., Sadhu, S., 2012) analyzed the hypothesis of the presence of 30 IJNCRDM, Volume 1, Number 1 January-March 2015 growing number of MFIs to over-borrowing, with a primary dataset that was generated through surveys conducted in eight districts of Andhra Pradesh (Mishra, S., Mall, M., Mishra, P.K., 2013)focused on the development of the Microfinance in India as a powerful instrument for poverty alleviation. (Sriram, M.S., 2010)studied about the standardized model of lending in commercial microfinance (Shil, P., Deb Nath, B., 2013 )studied about the role of Rural Credit Cooperative and SHG Model, in lending credit, and problems faced by them. (Roy, A., 2013) dealt with the microfinance programme in North-East India, the volume of savings, loan disbursement and loans outstanding. (Das, L., 2012)found an urgent need for improved governance to manage microfinance effectively for future growth (Roy, A., 2011) studied progress of microfinance in the North Eastern Region in terms of savings mobilization, loans disbursed, loans outstanding and non-performing assets. (Ghosh, M., 2012) analyzed the progress of SHG-Bank linkage programme regionally and nationally(Mahanta, P., Panda, G., Sreekumar, 2012)discussed three distinct aspects of microfinance, the growth of microfinance, the role played by NABARD in growth of SHGs and Grameen Bank, and the role government plays for protecting the micro-borrowers. (Kamath, R., Srinivasan, R., 2009)built a microfinance sector model and explained the reasons behind small loan sizes of high qualityfor multiple borrowings.(Devaraja T.S., 2011)discussed the factors associated with the development of microfinance based on a Win-Win scheme for both MFIs and their clients (Kusugal, P.S., 2014) studied Microfinance as a powerful instrument for poverty alleviation in the new economy (Singh, S., 2011)attempted to study the challenges faced by the micro finance sector in Bihar. (Das, P.K., 2014)discussed about the conceptual framework,development process, and services rendered bythe SHG linked microfinance programme and challenges faced by the Indian microfinance (Pramanik, B.K., Halder, M., 2013) with the help of consolidated data the paper analyzed the various trends and progress of the microfinance sector for the SHG–Bank Linkage model and MFI–Bank Linkage model. 3. Objectives: To make a comparative study of the Regional Rural Banks of Odisha on the basis of the number of Self-Help Groups, Savings Amount of the SHGs, Total Loan Disbursed by SHGs, Outstanding Loan and NPA of the SHGs, for SHG Scheme, SHG under SGSY scheme, and WSHG scheme. Lastly, make an attempt to analyze and interpret the reasons for the differences. 4. Research Design: A percentage is calculated, considering 2009-2010 as the base year for all the factors. The formula can be stated as: Current Year/Base Year * 100. 31 IJNCRDM, Volume 1, Number 1 January-March 2015 5. Research Methodology: In the present study, the Regional Rural Banks of the eastern region has been taken into account. The study was purely based on the secondary data, ‘The status of Microfinance in India’ a report, published by NABARD. The study was performed on, Baitarani Gramya Bank, Kalinga Gramya Bank, Neelachal Gramya Bank, Rushikulya Gramya Bank, Utkal Gramya Bank were the five banks under Odisha, which have been studied from 2009-10 and 2011-12, and Odisha Gramya Bank, and Utkal Gramya Bank in 2012-13, Odisha Gramya Bank was the new name given to the merger of Baitarani Gramya Bank, KalingaGramya Bank, Neelachal Gramya Bank, and Utkal GB was the new name for the merger version of Utkal Gramya Bank and Rushikula Gramya Bank. The analysis was done on the basis of comparison, with 2009-2010 as the base year, an effort has been made to analyze the percentage changes in the other years, a rank has been given to the states accordingly, on the basis of the four factors, Progress under Microfinance – Savings of SHGs with Regional Rural Banks, Bank loans disbursed by Regional Rural Banks to SHGs, Bank Loans outstanding against SHGs, and NPAs against Bank loans to SHGs. 6. Performance of RRBs of Odisha: National Bank for Agriculture and Rural Development (NABARD) has been extending credit supply to Odisha State Government by way of refinance through the banks and Odisha State Financial Corporation, for developing social and economic infrastructure of Odisha, from the Rural Infrastructure Development Fund (RIDF). (Role of Institutional Credit, 2013)Though Orissa started late in the SHG movement, substantial progress has been noticed over the years in SHGBank linkage. According to a report in 2004, Orissa stood first in performance criteria for the Eastern Region, in linking the SHGs and credit linkage, which exceeded the milestone of rupees one lakh mark by 2004, November. (Empowered Woman a Vision Document for micro-Finance in Orissa, 2009) Like the other two states, the microfinance status of Odisha has been studied for the three years 2010-11, 2011-12, and 2012-13, in comparison to 2009-10, for the three schemes, normal, SGSY and WSHG. It was observed that in the year 2010-11 both the number of SHG and total savings had an increasing curve, the first was increased by 107.7% and second one increased by 104.7% for the normal scheme, 116.6% and 114.35% for SGSY scheme and 106.1% and 110.1% for the WSHG scheme. In 2011-12 it was 122.36% and 94.93% respectively for normal scheme, 74.75% and 96.51% for the SGSY scheme, and 99.26% and 82.99% for the WSHG scheme and lastly in the year 2012-13 the percentages were 131 and 102.77, for the 32 IJNCRDM, Volume 1, Number 1 January-March 2015 normal scheme, 5.8% and 227.8% for the SGSY scheme and 134.99% and 108.19% for the WSHG scheme. (Table 3) The number of SHGs and total loan disbursed had an uneven curve, sometimes it was observed to have raised a small extent, sometimes it fell below the minimum level. In 2010-11, for the normal scheme it was 100.9% and 112.5% respectively, 155.9% and 141.7% for the SGSY scheme, and 99.4% and 106.1% for the WSHG scheme. In 2011-12 it was noticed that all the values had a diminishing curve, it was only 64.7% and 94.3% for normal scheme, 52.9% and 67.1% for the SGSY scheme and finally 56.8% and 72.4% for the WSHG scheme, in comparison to the base year. (Table 4) But it was found that the percentages for the outstanding loan had an increasing trend, in comparison to 2009-10. The percentage of SHGs and outstanding loan was 113.1% and 125.1% for normal scheme, 119.3% and 114.7% for SGSY scheme, 120.6% and 198.2% respectively for WSHG scheme in the first year, i.e. 2010-11. In 2011-12 the percentages were 102.9 and 111 for normal scheme, 72 and 101 for SGSY scheme, and 81.9 and 143.9 for WSHG scheme. In 2012-13 it was 88.4 and 161 for normal scheme, 269.5 and 145.7 for SGSY scheme, and finally 97.7 and 248.1 for the WSHG scheme. (Table 5)It was found that the NPA also increased accordingly for the following years. It was 200.8% for normal scheme and 189.7% for SGSY scheme in the year 2010-11, 102% for normal scheme and 15.7% for SGSY scheme, NPA for the SGSY scheme reduced significantly as noticed. In 2012-13 the NPA percentage was found maximum to be 495.8 for the normal scheme and 383.1 for the SGSY scheme over 2009-10. (Table 6) The functions carried by the MFIs and banks in Odisha were in a budding stage, and had lots of opportunities for expansion. The rise in this situation was due to the lack of experience and assessment mechanism in wholesale funding among bankers.SBI tried to appraise and approve bulk lending of 75 lakhs to “Swayamshree Micro- Credit Services” and has agreed to support Biswa and Gram Utthan.(Empowered Woman a Vision Document for micro-Finance in Orissa, 2009) 7. Conclusion: After analyzing the microfinance status of the four states in Odishal, by the merged regional rural banks, it was found that there has been an urgent need for the increase in microfinance and microcredit in the rural and interior areas, where people need to start their own livelihood by doing something on their own and save for their future contingencies. The SHGs as found tried their best to improve their services in the last three years, but it is further expected, and in the near future we would like to see every family having their quality of life. 33 IJNCRDM, Volume 1, Number 1 January-March 2015 Reference: 1.

Dr. Abhijit Dutta* Dr. Padmabati Gahan** Abstract The study test the weak form hypothesis of EMH for the Indian Stock Market by using daily data for Bombay Stock Exchange SENSEX for the period March 31 1998 to 1st April 2013. The paper indicate that Indian Stock Market indicates efficiency as random test and unit root test are similar and accept random walk for the market. The result of Auto correlation and Ljung Box test reject the hypothesis of random walk. As the variance ratio test is more effective tool than the other tests performed in the study, we go by the result of variance ratio test. The volatility persistence is due to the asymmetry in the available public information other than historic prices of stock indices and private information which is generally withheld by selected groups such as mutual funds, management, financiers and stock exchange officials. Key words: Efficient Market Hypothesis, Random Walk Hypothesis, ADF test and LB test 1.1 Introduction The capital market is based on information flows. How the market reacts is largely depended on the degree to which the participants of the market can use the information available to them. The markets are said to be efficient. This otherwise mean that the stock prices reflect and used the available information quickly. The more reactive the stock price is to the available information the more is the efficiency of the market. Fama (1970) noted that efficient markets is the market where there are large numbers of national profit maximizers’ actively competing with each other trying to predict the future market and where the current information is almost freely and equally available to all participants. Efficiency is almost freely and equally available to all participants. Efficiency of the market depends on the extent of absorption of information, the time taken for absorption and type of information absorbed. * Porfessor, MIMTS, Bhubaneswa, Odishar ** Professor Sambalpur Univeristy, Sambalpur, Odisha 37 IJNCRDM, Volume 1, Number 1 January-March 2015 The ability of the market to absorb information is of different degree. Fama(1970) classified efficiency in three groups as below: 1. 1 Weak Form This form asserts that he past prices are already absorbed by the market and any attempt to predict prices on the basis of historical information is totally futile as future changes are independent of past price changes. Hence, the market efficiency and the predictability of price change in stock market are inversely related. 1.2. Semi Strong Form The semi strong form of Efficient market Hypothesis (EMH) postulates that market absorbs quickly and efficiently all the publicly available information as well as information regarding historical process. As prices adjust to information quickly superior profits cannot be earned on a consistent basis. 1.3. Strong form According to strong form EMH, prices of securities fully reflect all available information both public and private. If this form is true, prices reflects than information to the selected groups like mutual funds, management financiers and stock exchange officials. Thus, according to this form no information that is available be it public or insiders can be used consistently to earn superior returns. In practice this extreme form of market efficiency hypotheses is very unlikely to hold since there are positively trading and information costs. 2. Review of Literature Ample numbers of researches have been done on efficient market hypothesis. Pioneering works of Fama (1965) developed this theory. Later Fama (1970), introduced the concept of three form of EMHs. The first order auto correlations were positive for 23 of the 30 companies and they were significant for 11 of the 30 companies. Cooper (1982) analyzed the world stock market s by taking 36 countries. The study observes that the markets in USA and UK as efficient based on random walk hypothesis. Sharma and Kennedy (1977) used run test and spectral analysis and concluded that all these markets analysis were strong form of EMH for BSE, NYSE and LSE and conformed that all these markets were efficient using random walk hypothesis. Barua (1981) and Gupta (1985) found that the Indian market were weak form efficient. Later Bhaumik (1977) annual prices closely represent a random variable. Ramasastri (1999) tested Indian Stock Markets for random walk using Dickey –fuller unit root test and study supports the null hypotheses that stock prices are random walk. 38 IJNCRDM, Volume 1, Number 1 January-March 2015 Mitra (2000 a, b )developed a neural network model and disapproved the random walk hypothesis for BSE Index. Chaudhuri and Yangru (2003) investigated whether stock prices indices of seventeen emerging markets can be characterized as random walk (through unit root) or mean reversion process implementing a test that can account for structural breaks in the underlying series and is more powerful than standard tests. Dutta (2010) tested for volatility using asymmetric GARCH and concluded that the volatility in Indian market is spurious and does not support the random walk. Several other studies over the period including Ahmad et al (2007), Worthington and Higgs (2003) suggested that Asian markets show weak form hypothesis using the unit root process. The literature shows mixed results about the efficiency of the Indian and other stock exchanges. Since SEBI has made rigorous arrangement to reform the Indian Capital market in order to increase the market efficiency. However the papers do not try to relate reform to the stock market efficiency in Indian Context. This paper tries to understand and test the random walk hypothesis for the Indian stock market using SENSEX series for long period of March 31 1998 to 1st April 2013 during which different phases of stock market reform happened as noted in the table 1.1 below. Table 1.1 Reforms of the Indian stock market Year 1992 1995 1996 Reform SEBI Created to regulate Indian Capital Market; NSE set up in Mumbai Bombay Online Trading Introduced The Depositaries Act enacted for dematerialized trading, SEBI reconstituted governing boards of stock exchanges; capital adequacy norms introduced; screen based trading extended to all the exchanges for expanded trading. 2000 Derivative trading introduced 2002 Compulsory rolling settlement for all kinds of scrips introduced ; Compulsory trading of shares of all companies listed in stock exchanges in DEMAT.. 2003 Settlement Guarantee to reduce counter party risk 2004 Rationalization of Margin trading system Source: Various sources and SEBI website. 4. Methodology In the present study several econometric models were used to check the random walk hypothesis for the Indian stock market with reference to BSE. 4.1 Unit root test A data set is said to be stationary if its mean and variance are constant over time and the value of covariance between two time periods depends only on the distance or lag between the two periods and on the actual time at which the covariance is computed. The correlation between a series and its lagged 39 IJNCRDM, Volume 1, Number 1 January-March 2015 values are assumed to depend only on the length of the lag and not when the series started. A series observing these properties is called a stationery time series. It is also referred to as a series that is integrated of order zero or as I(o). The unit root test checks whether a series is stationery or not. Stationery condition has been tested using Augmented Dickey-Fuller (ADF). For this the following types of ADF regression has been applied. n ∆Yt = α1 Yt-1 + Σ βm ∆Yt-m + μt …….. equation 1. m=1 n ∆Yt = αo + α1 Yt-1 + Σ βm ∆Yt-m + μt …….. equation 2. m=1 Where μt is white noise. The additional lagged terms have been included to ensure that the errors are uncorrelated. The following hypotheses have been tested by applying unit root test as given below. Ho = Yt is not I (0) and Ho = Yt is I (0) This means that Yt is not integrated of order zero in null hypothesis and Yt is integrated of order zero in alternate hypothesis. If the calculated value of ADF statistics are higher than their critical values from fullers table, then the series are non stationery or not integrated of order zero and vice versa. 4.2 Auto correlation function (ACF) The auto correlation function is another alternative for testing random walk hypotheses for stock index series. It was defined by Barlett (1946) as: ^ ^ Ρk = Yk / Yo ................................................................... equation 3. ^ ^ Where Yk is the covariance at lag k and Yo is variance at lag k which are expressed as follows. 40 IJNCRDM, Volume 1, Number 1 January-March 2015 ^ Y k = Σ ( Yt - Y ) ( Yt+k - Y)/n …………………………….. equation 4 ^ Yo = Σ ( Yo - Y )2 /n …………………………………………….. equation 5 Thus ρ can be finally rewritten as follows; n-k Σt=1 ( Yt - Y ) ( Yt+k - Y) ρ = ----------------------------n Σ ( Yo - Y )2 t=1 If the prices changes of the stocks are random then, ρk for the first differences of stock index series will be zero for all time lags. Standard error of ρk’ *SE (ρ ) + can be estimated as below: SE = 1/ Ѵn Here, SE standard error and n stands for number of observations. The hypothesis of the autocorrelation test is; Ho = Auto correlation coefficient are equal to zero Hα = Auto correlation coefficient are not equal to zero Ljung and Box test is applicable to test the joint hypotheses that all ρk autocorrelation coefficient are simultaneously equal to zero. 5. Analysis of the results 5.1 Unit root test. Unit root test is conducted for the period March 31 1998 to 1st April 2013. Since the basic assumption of the random walk hypothesis is that if stock index (here SENSEX) series follow random walk then these series will be non stationery at levels and their first difference will be random variable. Therefore for the study, the period has been broken into three period of 31st March 1998 to 1st April 2002 (hence forth called as period 1), 2nd April 2002 to 1st of April 2008 (henceforth called as period 2) and 2nd of April 2009 to 31st March 2013 (henceforth called as period 3). There after ADF has been taken into 41 IJNCRDM, Volume 1, Number 1 January-March 2015 consideration for these periods as well as for the entire period. Table 1.1 shows the result of the ADF tests. Table 1.1 Augmented Dickey-Fuller Unit Root Test Series or periods SENSEX (period 1) st SENSEX (1 difference of SENSEX series at period 1) SENSEX (period 2) st SENSEX (1 difference of SENSEX series at period 2) SENSEX (period 3) st SNSEX (1 difference of SENSEX at level 3) SENSEX (overall period) st SENS (1 difference for the overall period) ADF Test Statistics - 1.46 -13.66 At 5% confidence level -1.68 -1.68 P-value 0.13 0.00 -2.05 -23.42 -1.86 -1.86 0.16 0.00 -2.88 -28.75 -1.86 -1.86 0.00 0.00 -2. 21 -1.86 0.00 -45.66 -1.86 0.00 The above table shows that for all the three periods separately and the overall period the series of SENSEX is non-stationery but stationery when the first difference of theses series are been considered. It can be thus concluded on the basis of the unit root test, that SENSEX follow a random walk hypothesis and Indian stock markets are efficient. 5.2 Autocorrelation and Ljung-Box Test The autocorrelation coefficients for the first order differences are presented in the table 1.2 below.

The autocorrelation coefficients for a lag up to 37 periods are reported here for all the three periods and the overall period. The results shows that autocorrelation coefficients are significant for the 1st period at lags 1, 3 ,6 ,7 ,10, 13, 15 ,19, 22 and 24. Similarly for the 2 nd period the autocorrelations are significant for the lags 3, 5, 7, 9, 11, 14,16, 19, 21, 24, 27, 29, 32, 34, 36. For the 3rd period the autocorrelations are significant at the lags 1, 3, 8, 11, 12, 14, 15, 17, 20, 21, 24, 25, 28, 30, 31, 35 and 37 and for the overall period at 1, 4, 8, 11, 13, 14, 15, 17, 20,21,24,28, 30, 31, 35 and 37. The null hypothesis that p=0 is not rejected. Hence, the autocorrelation test indicates that the Indian stock market remained inefficient during all the period despite several steps taken to increase its efficiency. 43 IJNCRDM, Volume 1, Number 1 January-March 2015 Table 1. 3 Ljung-Box Q statistics of first difference of the SENSEX series st nd rd Lag 1 period 2 period 3 period 37 145.14* 60.63* 98.67* Significant at 1% level of significance Overall period 110.98* The table above which shows the Ljung-Box statistics for the joint significance of the autocorrelations at a selected lag of 37. L-J statistics is found to be significant at 1% level for all the three levels as well at the overall level. The L-B statistics thus rejects the random walk hypothesis. Hence both autocorrelation coefficients and L-B statistics rejects the random walk hypotheses. 6. Conclusion This study is directed at studying the efficiency of the market by using a period of fifteen years data from the Bombay Stock Exchange and try to understand whether the EMH in its weak form hold good for the market or not. For the study Unit root test and autocorrelation were used along with L-B statistics. The unit root test confirms the random walk where as the other two methods reject it. Since the variance ratio test is more powerful than the usual Dickey Fuller test we can safely conclude that random walk does not hold good for the Indian Market at this period of time. The results are consistent for all the three split periods. This means that future stock prices cannot be predicted on the basis of the historical prices. We further observe that volatility continues even after measures to reform the market in all the three period for which we carried out the unit root test. The reasons may be many and cannot be sharply focus. But one can guess that integration of the market to the global market especially to that of Europe and America could make the volatility contagious. During this [periods there were large number of FII activities which could have increased the informational asymmetry in the market. It is imperative that policy makers make necessary steps to increase the information sharing in the market and free float of equity in the market. This will enable a better control on volatility and help in improving the market efficiency in India. 44 IJNCRDM, Volume 1, Number 1 January-March 2015 References: 1.
