This book was released on 2010 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the Nigerian Stock Exchange (NSE) has witnessed an unprecedented growth in market capitalization, membership, value and volume traded. By December 2007, the All Share Index has grown massively to 57,990.2 from 1113.4 in January 1993. This rising interest in investment opportunities in the NSE raises questions about its efficiency. This paper, therefore, tests the Weak-form Efficient Market Hypothesis of the NSE by hypothesizing Normal distribution and Random walk of the return series. Monthly All Share Index of the NSE is examined from January 1993 to December 2007. Our Normality tests include Skewness, kurtosis, Jarque-Bera and Studentized Range tests; whereas Random walk is tested using the non-parametric Runs test. Results of the Normality tests show that returns from NSE do not follow normal distribution. Runs test results reject the randomness of the return series of the NSE. Overall results from the tests suggest that the NSE is not weak form efficient. Reduction of transaction cost so as to improve market activities and Minimizing institutional restrictions on trading of securities in the bourse were therefore recommended.

By December 2007, the All-Share Index has grown massively to 57,990 from 1,113 in January 1993. This rising interest in investment opportunities in the NSE raises questions about its efficiency. Why do we care if a stock market is efficient or not? The stock market acts an intermediary and channels funds from savers to firms for investment purposes. An efficient stock market is a 'well-functioning' market, where prices of stocks represent their fair value. This book examines the efficiency of the NSE using a scientific method that can be replicated by stakeholders of stock market such as investors, investment analysts, fund managers, regulators, and students of the stock markets.

Available in PDF, EPUB and Kindle. Book excerpt: This paper examines the weak-form efficient markets hypothesis for the Nigerian stock market by testing for random walks in the monthly index returns over the period 1984-2009. The results of the non-parametric runs test show that index returns on the Nigerian Stock Exchange (NSE) display a predictable component, thus suggesting that traders can earn superior returns by employing trading rules. The statistically significant deviations from randomness are also suggestive of sub-optimal allocation of investment capital within the economy. The findings, in general, contradict the weak-form of the efficient markets hypothesis. Finally, a range of policy strategies for improving the allocative capacity and quality of the information environment of the NSE are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Efficient Market Hypothesis is the cornerstone of modern financial theories. As the tests of market efficiency firstly started from developed markets, the studies on these markets are more in numbers compared with that of on emerging markets. Dhaka Stock Exchange (DSE) is an emerging market of South Asia. The current study has tested this market against weak form market efficiency by using a set of Parametric (serial correlation coefficient test, unit root test, ARIMA) and Non-parametric tests (runs test, Kolmogorov Smirnov test, Shapiro Wilk test) on DGEN and DSE 20 index (two indices of DSE) for the period of 2002-2010 and has concluded that the market is not weak form efficient.

This book was released on 2010-11 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research Paper (undergraduate) from the year 2008 in the subject Business economics - Investment and Finance, grade: 1.7, The FOM University of Applied Sciences, Hamburg, language: English, abstract: Especially after the 90ies, where the stock markets raised enormously, many private investors joined the stock market and were blended by abnormal profits and neglected possible losses. The same behavior could be observed before the Financial Crisis became reality. But each endless raising stock market would finally collapse, because stock prices are randomly and only driven by relevant news. The adjustment to the news is quickly. This is the theoretical argumentation of the Efficient Market Hypothesis (EMH), which will be evaluated in this paper. The author gives an overview about the EMH by explaining the basic principles and its mathematical formulation. The practical part evaluated the EMH on selected examples, where the theory could only be partly approved.

Available in PDF, EPUB and Kindle. Book excerpt: The efficient market hypothesis (EMH) suggests that stock prices fully reflect all available information in the market and no investor is able to earn excess return on the basis of some secretly held private, public or historical information. Efficient market hypothesis (EMH) can be further divided into three sub hypotheses depending upon the information set involved and these are weak form efficient market hypothesis, semi strong form efficient market hypothesis and strong form efficient market hypothesis. This research has examined the weak form of efficient market hypothesis on the four major stock exchanges of South Asia that are Karachi stock exchange (KSE-100), Bombay stock exchange (BSE-SENSEX), Colombo stock exchange (CSE-MPI) and Dhaka stock exchange (DSE-GEN). Historical index values of KSE-100, BSE-SENSEX, CSE-MPI and DSE-GEN on a monthly, weekly and daily basis for a period of 14 Years (July 1997 to June 2011). We applied four different statistical tests including runs test, serial correlation (Durbin Watson test), unit root and variance ratio test. Findings suggest that none of the four major stock markets of south-Asia follows Random-walk and hence all these markets are not the weak form of efficient market.

Available in PDF, EPUB and Kindle. Book excerpt: This empirical study is conducted to test the weak-form market efficiency of the stock market returns of Pakistan, India, Sri Lanka, China, Korea, Hong Kong, Indonesia, Malaysia, Philippine, Singapore, Thailand, Taiwan, Japan and Australia. Monthly observations are taken for the period January 2004 to December 2009. Autocorrelation, Ljung-Box Q-statistic Test, Runs Test, Unit Root Test and the Variance Ratio are used to test the hypothesis that the stock market follows a random walk. Monthly returns are not normally distributed, because they are negatively skewed and leptokurtic. In aggregate we concluded that the monthly prices do not follows random walks in all the countries of the Asian-Pacific region. The investors can take the stream of benefits through arbitrage process from profitable opportunities across these markets.

Available in PDF, EPUB and Kindle. Book excerpt: The analysis ofwhat might be called "dynamic nonlinearity" in time series has its roots in the pioneering work ofBrillinger (1965) - who first pointed out how the bispectrum and higher order polyspectra could, in principle, be used to test for nonlinear serial dependence - and in Subba Rao and Gabr (1980) and Hinich (1982) who each showed how Brillinger's insight could be translated into a statistical test. Hinich's test, because ittakes advantage ofthe large sample statisticalpropertiesofthe bispectral estimates became the first usable statistical test for nonlinear serial dependence. We are forever grateful to Mel Hinich for getting us involved at that time in this fascinating and fruitful endeavor. With help from Mel (sometimes as amentor, sometimes as acollaborator) we developed and applied this bispectral test in the ensuing period. The first application ofthe test was to daily stock returns {Hinich and Patterson (1982, 1985)} yielding the important discovery of substantial nonlinear serial dependence in returns, over and above the weak linear serial dependence that had been previously observed. The original manuscript met with resistance from finance journals, no doubt because finance academics were reluctant to recognize the importance of distinguishing between serial correlation and nonlinear serial dependence. In Ashley, Patterson and Hinich (1986) we examined the power and sizeofthe test in finite samples.

Book excerpt: The rapid growth and development of emerging economies offer both opportunities and threats for international businesses. Understanding the economic development of emerging markets, combined with a knowledge of the increasingly complex international business market, enables better exploitation of opportunities in increasingly competitive world markets. The BRIC countries, the most prominent emerging markets, have long been discovered by foreign firms due to their enormous potential for investment opportunities. This book offers a comprehensive look at emerging markets, especially as they integrate with the global economy. It offers a conceptual framework to analyze emerging markets from multiple perspectives, including those of indigenous entrepreneurs struggling to overcome constraints to build world-class businesses, multinationals from developed countries tapping into emerging markets for their next growth spurt, and domestic and foreign investors seeking to profit from investment opportunities in emerging markets.
Download or read book Indian Stock Market written by Gourishankar S. Hiremath and published by Springer Science & Business Media. This book was released on 2013-10-28 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: India is one of the major emerging economies of the world and has witnessed tremendous economic growth over the last decades. The reforms in the financial sector were introduced to infuse energy and vibrancy into the process of economic growth. The Indian stock market now has the largest number of listed companies in the world. The phenomenal growth of the Indian equity market and its growing importance in the economy is indicated by the extent of market capitalization and the increasing integration of the Indian economy with the global economy. Various schools of thought explain the behaviour of stock returns. The Efficient Market Theory is the most important theory of the School of Neoclassical Finance based on rational expectation and no-trade argument. The book investigates the growth and efficiency of the Indian stock market in the theoretical framework of the Efficiency Market Hypothesis (EMH). The main objective of the present study is to examine the returns behaviour in the Indian equity market in the changed market environment. A detailed and rigorous analysis, made with the help of the sophisticated time series econometric models, is one of the key elements of this volume. The analysis empirically tests the random walk hypothesis and focuses on issues like nonlinear dynamics, structural breaks and long memory. It uses new and disaggregated data on recent reforms and changes in the market microstructure. The data on various indices including sectoral indices help in measuring the relative efficiency of the market and understanding how liquidity and market capitalization affect the efficiency of the market.
