Capital market efficiency Capital market efficiency 0 Introduction The performance of markets under different economic and political conditions has been highly explored in the literature.

According to the theory of the efficient as prices react to similar information there is no investor who will be in a position to earn superior profits over the other.

This kind of observation is seen in strong form efficiency where all available public information is incorporated in the stock’s price (Zhang, 2008; p. Using the random Walk theory asserts that in any efficient market, prices normally become unpredictable such that they are random.

In growth times (bull markets) or during uncertainty (bear markets) the polarity of the signals automatically changes as a result of relative risk aversion of the investors.

Hence, during bull markets, even the companies not rated high may still enjoy a rally and during bear markets, even the best-performing companies may suffer crash of security prices. pp23-26) suggest that during uncertainty, the mapping from the endowments, and individual preferences & belief in the prices drive the capital market equilibrium.As such, it should be impossible to outperform the overall market through expert stock selection or market timing, and the only way an investor can possibly obtain higher returns is by purchasing riskier investments.Although it is a cornerstone of modern financial theory, the EMH is highly controversial and often disputed.In fact, it has been revealed that informational efficiency is......?Market Efficiency Private market efficiency refers to the measure of access to information that market players can use to maximize their gains on investment at a minimum transaction cost (Jarrow & Larsson , 2011).One of the most important challenges that modern markets have to face seems to be the following one: the information related to events that can influence the price of securities and other financial products are often incorrect.On the other hand, it has been proved that information can highly affect the market performance.Data compiled by Morningstar Inc., in its June 2015 Active/Passive Barometer study, supports the EMH.

The study found that year-over-year, only two groups of active managers successfully outperformed passive funds more than 50 percent of the time—U. small growth funds and diversified emerging markets funds. The internal information being revealed to the stock markets is termed as "dimensions of signal space" whereby empirical researches suggest that a smaller relative signal space for a large number of assets result in fully revealing equilibrium prices. pp1325-1327) proved that efficient market hypotheses cannot be viewed from the ideal perspective whereby the signals (of internal information) and the corresponding return on assets need not be normal if the dimension of signal space is larger for a smaller number of assets.
