Efficient Market Hypothesis (EMH) History and

Efficient Market Hypothesis (EMH) History andPART 2 EFFICIENCY MARKET speculationIntroductionIn order to better understand the origin and the idea behind the Efficient Market Hypothesis (EMH), an overview of the EMH, The Random Walk Model, different degrees of reading capability and the implications of efficient marketplaces for investors ar studied in the paper.Efficient Market HypothesisThe strength concept is one of the most essential concepts for investment care and abridgment. Market efficiency basically revolves around three related assumptions on proper- allocation efficiency, informational efficiency and ope dimensionnal efficiency. competency in allocation is a resilient characteristic of a soused market wherein the allocation of capital is done in a proper way so that it benefits all the participants and helps in advancement of economic growth and status.Efficiency in operation is another of import parameter which is used commonly by economists to determine an d analyzes how resources are utilized in the market to benefit operational activities in the market and industry.Efficiency in information helps to determine the actual market value of shares found on its unalien up to(p) value. The Information efficiency signifies that reflection on all available information pertaining to the credentials terms must be used to determine the securitys observed market price. (Hossain,Rahman, 2006)The introduction to the idea of market efficiency was given by Bachelier (1900) and later it was termed as efficient market by Fama (1965)Fama (1970) supercharge went on to state the vital conditions/ assumptions for maintaining efficiencyProvision of no transactional costs during the trading of securitiesAll information is freely available to all the participants in the market, and parallelism of all of them on the implications of the information relating to the current price and future distribution of prices of each securityHe identify three forms of i nformational efficiency, which are the weak form(underdeveloped), the semi- slopped form(developing) and the strong form efficiency(developed).Forms of Market EfficiencyWeak-Form EfficiencyWeak form efficiency market implies that it is an efficient market which reflects all its market information accu putly and does not provide profit for the investor based on ult records or rates. This past records stands invalid for the market. Fama (1970) stipulates in his speculation that no investor can avail greater returns when the market is weak-form efficient. Example African economy has a weak efficiency market wherein the means to attain gains on investment is narrow based on past investment experience. Example trading test, auto correlation test and run test.Semi-Strong Form EfficiencySemi Strong Form Efficiency market indicates that market is efficient and it reflects all humans information. It says that the stocks are absorbant of all new information and incorporates it by adjusting to it. It is partly like the weak form efficiency market wherein the stocks rate are based upon new information that is released after the stocks are bought. So making it difficult for the market to be predictable. Fama (1970) explains the semi-strong form efficient market as the one where share price not only reflect on all information regarding its past and historic prices, but also includes additional usual information which is later on integrated with the shared price and adjusted to reveal the true share value. This also implies that an investor will not be able to use the public information for the generation of gains in the evolving stock market. Event tests and time series/ regression tests are some examples.Strong Form EfficiencyThe Strong form efficient market relies on both public as well as private information wherein the stock prices are based and reflected upon. So an average investor cannot make much profit more than others also when he is given the new information. It incorporates both the weak form and semi strong form of market efficiency. Private information concerns the information that is not yet published or known only to the security analysts/ fund managers. The new public and private information is then incorporated into the share price to represent its true share value. This makes it even more difficult for the investor to assess share values. Examples are insiders, exchange specialists, institutional money managers and analysts who have access to new information.Fundamental compendium and adept analysisThis analysis makes use of analysing and evaluating the financial statements, health of the business, efficiency of the management and their competitive advantages, while also examining the competition in the market. When applied on forex and futures market it uses production, interest rates, earnings, GDP, employment, manufacturing, housing and management analysis.While technical analysis predicts the future of market based on past prices, volume and market information. This is useful for behaviour economics and quantitative analysis. Both these methods of analysis contradict the exposit and study made on efficiency market theory which states that study of market with accuracy cannot be determined by any method.Implications of EMHMarket efficiency has some prominent implications concerned with both authorities and investors, which are mentioned belowWhen a market is efficient they must1. Not worry about analysis on their investments, but concentrate rather on developing a diversified portfolio to get rewarded for their investments.2. Adopt to the policy of buy and hold after establishing their portfolios as making frequent changing by shifting from one securities group to another would raise for them unwarranted transaction costs.Other implications are based on the fact that changes in price are random and cannot be predicted, investors are smart enough to not get fooled by the financial reports circulated a nd lastly the measure of security issues are not crucial.Investors must pay more attention to construct and hold diversified and efficient portfolios rather than taking to fundamental and technical analysis. This approach will definitely benefit them in the long run.Empirical Evidences for anomaliesThe experiential evidence lists some of the significant anomalies which contradict the efficient market theory as listed belowThe January EffectIt is often noticed that the stock returns raise high abnormally in the first week of January which is defined as the January resultant wherein most of the investors opt to sell some of the stocks befor the year end and later claim for a capital loss to evade tax and then go on to make their reinvestments later on. (Rozeff and Kinney, 1976)Size EffectThe Size Effect is the small firms tendency, which holds a small capital market, to outweigh and spend the market of larger companies and rise as an underdog over the long term. (Banz, 1981) and ( Reinganum, 1981)Weekend EffectThis is a notable phenomenon wherein the stock returns are observed to be comparatively lower on Mondays as against those on the preceding Fridays. ( French, 1890)..Value EffectThe value effect related to the nature of stocks that hold low cost, earnings ratio to outdo other alternative portfolios of stocks which have higher cost, earnings ratio.Empirical Evidences from Developing CountriesDespite huge empirical studies conducted in order to test and underpin the Efficient Market Hypothesis in developed countries which witness a flourishing financial market, the pertinent studies on weak efficiency markets are circumscribed in countries like Africa. Most developing and underdeveloped countries suffer a setback due to the problem of thin trading (Mlambo and Biekpe, 2005). Fisher (1966) who first identified this bias due to thin trading on his observation on correlation of return index, stated that the securitys price that are put down are not similar to their respective underlying values based on theory as when a share trade fails, the recorded price remains the closing price as per the last share trade. It is also stressed that reasons like transactional costs, delay in operations and illiquidity of the market are crucial in determining a concrete statistical evaluation of the study.BibliographyCohen, W.
