Master's Thesis from the year 2016 in the subject Business economics - Banking, Stock Exchanges, Insurance, Accounting, grade: 1,3, RWTH Aachen University (Faculty of Business and Economics), course: Corporate Finance, language: English, abstract: In order to fill a gap in the research on developing equity markets, especially emerging markets, this study deals with market anomalies in the BRIC countries, specifically focusing on identifying the anomalies size and price-to-book effect. However, the reason for an analysis regarding stock market anomalies in the BRIC countries is not exclusively limited to the lack of contemporary studies on this topic. The emerging markets in general, and, specifically, the BRIC stock markets are very interesting and valuable objects for respective examinations, since they still provide an enormous growth potential. The markets naturally show a high volatility. This study¿s approach is to explain the established market anomalies and point at factors, which may enforce size and price-to-book effects in each BRIC country. Therefore, after presenting the BRIC concept in chapter 2, the standard method to estimate the stock return, the Capital Asset Pricing Model (CAPM), is introduced in chapter 3 in order to identify possible weaknesses and certain anomalies, which have been identified in the research. The most common anomalies will be introduced in chapter 4. Subsequently, an alternative method to explain the stock return, the Fama / French three-factor model is discussed as a possibility to identify further risk factors, which can invalidate anomalies with respect to the CAPM, in chapter 5. Furthermore, a brief overview on previous studies, which include valuation anomalies in the respective countries, is given in chapter 6. In the empirical part of chapter 7, each country is analyzed individually with respect to size and price-to-book effects. However, the study applies the same empirical analysis for each stock market in order to obtain comparable results, choosing a timespan, which covers the maximum period for which sufficient data is available in all stock markets. Two approaches are used per country. The first, to identify the mentioned stock market anomalies, the second to explain the cross-section of stock returns by means of three proxies for risk, namely systematic risk in form of CAPM-beta, size and book-to-market equity ratio. The empirical part of this examination investigates the time frame from January 1996 until June 2015 and uses a total sample of 6,054 stocks throughout the four stock markets. In the conclusion, the study¿s results are summarized and findings presented.
