Empirical Challenges to the Efficient Market Hypothesis 1. Introduction Random walks observed in stock return series prior to the 1970s puzzled a number of financial theorists and practitioners. In 1970‚ this puzzle was resolved by Eugene Fama (1970) who argued that the random walks observed in the behaviour of stock return series could be attributed to market efficiency. Market efficient meant that investors could not consistently make risk-adjusted returns by making investment decisions

Empirical Evidence The study of addiction has included alcoholism and drug addiction for a long time. The recent obesity epidemic has brought food addiction as a serious concern even though it is still a controversial issue. It is difficult to accept the idea of food being an addiction. Addiction has been defined as” a primary‚ chronic disease involving brain reward‚ motivation‚ memory and related circuitry.”(Whitepaper) There are numerous studies and research that support the fact that over

Yurop Shrestha Economics Thesis CAPM vs. APT: An Empirical Analysis Introduction The Capital Asset Pricing Model (CAPM)‚ was first developed by William Sharpe (1964)‚ and later extended and clarified by John Lintner (1965) and Fischer Black (1972). Four decades after the birth of this model‚ CAPM is still accepted as an appropriate technique for evaluating financial assets and retains an important place in both academic scholars and finance practitioners. It is used to estimate cost of capital

1 “Arithmetic vs. Geometric Means: Empirical Evidence and Theoretical Issues” by Jay B. Abrams‚ ASA‚ CPA‚ MBA Copyright 1996 There has been a flurry of articles about the relative merits of using the arithmetic mean (AM) versus the geometric mean (GM). The Ibbotson SBBI Yearbook took the first position that the arithmetic mean is the correct mean to use in valuation. Allyn Joyce’s June 1995 BVR article initiated arguments for the GM as the correct mean. The previous articles have centered
