Write 6 pages with APA style on The Relationship between Rationality of Investors and Market Efficiency. In an efficient market, significant information is freely accessible to all participants. Researchers argue that with the current availability and utilization of complicated modeling in capital markets and with substantiality superior revelation and analysis, superior approximations of returns may be made by expert investors (Keim &. Ziemba, 2000, p. 255). These computations of returns approximations are possible where there are efficient market mechanisms. Therefore, there is a positive relationship between market efficiency and rationality of investors. (Jones, 2009, p. 329).
.In 1900, Louis Bachelier developed hypotheses of investment payoffs. Keim &. Ziemba The Efficient Market Hypothesis is one of these theories of investment payoffs. The Efficient Market Hypothesis hypothesizes that, at any given time, equity prices fully replicate all accessible information. The propositions of the efficient marketplace hypothesis are profound (Fama, 1995, p. 4). Most traders who sell and buy equities do these under the postulation that the equities they are selling are worth below the selling price while equities they are purchasing are worth in excess of the price that they are disbursing. However, if there is an efficient market and current prices fully replicate all information, then selling and purchasing in an endeavor to outperform the marketplace will efficiently be a game possibility rather than expertise (Jones, 2009, p. 329).
