Available in PDF, EPUB and Kindle. Book excerpt: This study examines the adaptive market hypothesis of the S&P500, FTSE100, NIKKEI225 and EURO STOXX 50 by testing for stock return predictability using daily data from January 1990 to May 2014. We apply three bootstrapped versions of the variance ratio test to the raw stock returns and also whiten the returns through an AR-GARCH process to study the nonlinear predictability after accounting for conditional heteroscedasticity through the BDS test. We evaluate the time-varying return predictability by applying these tests to fixed length moving subsample windows. We also examine whether there is a relationship between the level of predictability in stock returns and market conditions. The results show that there are periods of significant return predictability, but also episodes of no significant predictability in stock returns. We also find that certain market conditions are significantly related to predictability in certain markets but each market interacts differently with the different market conditions. Therefore our findings suggest that significant return predictability in stock markets does vary over time in a manner consistent with the adaptive market hypothesis and that each market adapts differently to certain market conditions.

This book was released on 2014 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study addresses the question of whether the adaptive market hypothesis provides a better description of the behaviour of emerging stock market like India. We employed linear and nonlinear methods to evaluate the hypothesis empirically. The linear tests show a cyclical pattern in linear dependence suggesting that the Indian stock market switched between periods of efficiency and inefficiency. In contrast, the results from nonlinear tests reveal a strong evidence of nonlinearity in returns throughout the sample period with a sign of tapering magnitude of nonlinear dependence in the recent period. The findings suggest that Indian stock market is moving towards efficiency. The results provide additional insights on association between financial crises, foreign portfolio investments and inefficiency.

This book was released on 2009-10-03 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bachelor Thesis from the year 2009 in the subject Economics - Case Scenarios, grade: 1,3, University of Mannheim (Lehrstuhl für Volkswirtschaftslehre, insbes. Ökonometrie), course: Bachelorarbeit, language: English, abstract: In recent years foreign aid was often conditioned on good institutions. Due to this course the development of financial institutions has been considered vital for the development process. This thesis points in its theoretical part to the positive effects of efficient stock markets on economic growth and examines empirically the efficiency of Africa's sub-Saharan stock markets. Results are then compared with the same tests on four emerging markets in Asia and as a benchmark on S&P 500 and DAX. It discusses further the relationship between market efficiency and financial crisis and comes to the conclusion that a crisis worsens the respective efficiency level. Nevertheless, all African markets are at least able to pass the critical lowest hurdle of market efficiency. However, conclusions from the research propose, that the Asian markets perform better than the African markets, although the study comes to some inconclusive results. Limits to the efficient market hypothesis itself and its empirical analysis are shown throughout the paper. The study suggests that former reforms need to be intensified in order to avoid a further increase in overall income inequalities.

Download or read book Are African Stock Markets Inefficient Or Adaptive Empirical Literature written by Paul-Francois Muzindutsi and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This chapter reviews empirical studies on weak form of efficiency with the aim of establishing whether the African market is inefficient or adaptive. The reviewed studies are categorised based on their methodological approaches to compare the power of linear and non-linear models in testing for weak-form efficiency. The studies on calendar anomalies, an indication of weak-form inefficiency, are reviewed to assess whether these anomalies are adaptive as portrayed by the relatively recent theory of adaptive market hypothesis (AMH). The scope of reviewed studies is also extended to developed and emerging markets to gain a broad comparison of the findings. This review revealed that non-linear dependence has been revealed in stock returns suggesting that non-linear models are best fit to test for the stock market efficiency. Reviewed studies produced contradictory findings with some supporting and others rejecting weak-form efficiency. Thus, most studies support the AMH, which suggests that market efficiencies and anomalies are time changing. This chapter concludes that most of the existing studies on AMH have been carried out in markets other than Africa, and hence, further empirical studies on the evolving and changing nature of efficiency in African stock markets are recommended.

Available in PDF, EPUB and Kindle. Book excerpt: This paper models weekly index returns adjusted for thin trading as a nonlinear autoregressive process with conditional heteroscedasticity to investigate the weak-form pricing efficiency of 11 African stock markets. Specifically, the use of the EGARCH-M model allows us to capture how conditional volatility affects the pricing process without imposing undue restrictions on the parameters of the conditional variance equation. On the basis of such a robust model, we are able to reject the evidence in prior studies that the Nigerian stock market is weak-form efficient. On the other hand, we confirm extant results that the markets in Egypt, Kenya and Zimbabwe are efficient while that of South Africa is not weak-form efficient. We also generate new results, which point to the efficiency of the stock markets in Mauritius and Morocco, while the markets in Botswana, Ghana, Ivory Coast, and Swaziland are not consistent with weak-form efficiency.

Available in PDF, EPUB and Kindle. Book excerpt: The Efficient Market Hypothesis believes that it is impossible for an investor to outperform the market because all available information is already built into stock prices. However, some anomalies could persist in stock markets while some other anomalies could appear, disappear and re-appear again without any warning. A Special Issue on "Efficiency and Anomalies in Stock Markets" will be devoted to advancements in the theoretical development of market efficiency and anomaly in the Stock Market, as well as applications in Stock Market efficiency and anomalies.

Download or read book Risk Return Relationship and Portfolio Management written by Raj S. Dhankar and published by Springer Nature. This book was released on 2019-10-24 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers all aspects of modern finance relating to portfolio theory and risk–return relationship, offering a comprehensive guide to the importance, measurement and application of the risk–return hypothesis in portfolio management. It is divided into five parts: Part I discusses the valuation of capital assets and presents various techniques and models used in this context. Part II then addresses market efficiency and capital market models, particularly focusing on measuring market efficiency, which is a crucial factor in making correct investment decisions. It also analyzes the major capital market models like CAPM and APT to determine to what extent they are suitable for use in developing economies. Part III highlights the significance of risk–return analysis as a prerequisite for investment decisions, while Part IV examines the selection and performance appraisals of portfolios against the backdrop of the risk–return relationship. It also examines new tools such as the value-at-risk application for mutual funds and the applications of the price-to-earnings ratio in portfolio performance measurement. Lastly, Part V explores contemporary issues in finance, including the relevance of Islamic finance in the increasingly volatile global financial system.
Download or read book A Nonlinear Time Series Workshop written by Douglas M. Patterson and published by Springer Science & Business Media. This book was released on 2000 with total page 224 pages. 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.

This book was released on 2015-08-06 with total page 844 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The World Scientific Handbook of Futures Markets serves as a definitive source for comprehensive and accessible information in futures markets. The emphasis is on the unique characteristics of futures markets that make them worthy of a special volume. In our judgment, futures markets are currently undergoing remarkable changes as trading is shifting from open outcry to electronic and as the traditional functions of hedging and speculation are extended to include futures as an alternative investment vehicle in traditional portfolios. The unique feature of this volume is the selection of five classic papers that lay the foundations of the futures markets and the invitation to the leading academics who do work in the area to write critical surveys in a dozen important topics."--$cProvided by publisher.

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.

Available in PDF, EPUB and Kindle. Book excerpt: From acclaimed economists George Akerlof and Robert Shiller, the case for why government is needed to restore confidence in the economy The global financial crisis has made it painfully clear that powerful psychological forces are imperiling the wealth of nations today. From blind faith in ever-rising housing prices to plummeting confidence in capital markets, "animal spirits" are driving financial events worldwide. In this book, acclaimed economists George Akerlof and Robert Shiller challenge the economic wisdom that got us into this mess, and put forward a bold new vision that will transform economics and restore prosperity. Akerlof and Shiller reassert the necessity of an active government role in economic policymaking by recovering the idea of animal spirits, a term John Maynard Keynes used to describe the gloom and despondence that led to the Great Depression and the changing psychology that accompanied recovery. Like Keynes, Akerlof and Shiller know that managing these animal spirits requires the steady hand of government—simply allowing markets to work won't do it. In rebuilding the case for a more robust, behaviorally informed Keynesianism, they detail the most pervasive effects of animal spirits in contemporary economic life—such as confidence, fear, bad faith, corruption, a concern for fairness, and the stories we tell ourselves about our economic fortunes—and show how Reaganomics, Thatcherism, and the rational expectations revolution failed to account for them. Animal Spirits offers a road map for reversing the financial misfortunes besetting us today. Read it and learn how leaders can channel animal spirits—the powerful forces of human psychology that are afoot in the world economy today. In a new preface, they describe why our economic troubles may linger for some time—unless we are prepared to take further, decisive action.
Download or read book Behavioral Finance The Second Generation written by Meir Statman and published by CFA Institute Research Foundation. This book was released on 2019-12-02 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Behavioral finance presented in this book is the second-generation of behavioral finance. The first generation, starting in the early 1980s, largely accepted standard finance’s notion of people’s wants as “rational” wants—restricted to the utilitarian benefits of high returns and low risk. That first generation commonly described people as “irrational”—succumbing to cognitive and emotional errors and misled on their way to their rational wants. The second generation describes people as normal. It begins by acknowledging the full range of people’s normal wants and their benefits—utilitarian, expressive, and emotional—distinguishes normal wants from errors, and offers guidance on using shortcuts and avoiding errors on the way to satisfying normal wants. People’s normal wants include financial security, nurturing children and families, gaining high social status, and staying true to values. People’s normal wants, even more than their cognitive and emotional shortcuts and errors, underlie answers to important questions of finance, including saving and spending, portfolio construction, asset pricing, and market efficiency.
