Forms of Efficient Market (Strong, Semi Strong, Weak) • A Weak Form of EMH makes use of only historical information and states that all historical information found in past prices and volume of trade is reflected in current prices. Whenever you talk about you may find three forms of efficiency exists in the market. In this paper, we discuss the main ideas behind the efficient market hypothesis, and provide a guide as to which of its predictions seem to be borne out by empirical evidence, and which do not. Weak form EMH. A market is called efficient when resources are used in a way that maximizes the production of goods and services at the lowest cost. ! Nevertheless, this assumption is far stronger than that of weak-form efficiency. In other words, technicians – those trading on analysis of historical trading information – should earn no abnormal returns. Rational investors have difficulty profiting by shorting irrational bubbles because, as John Maynard Keynes commented, "markets can remain irrational far longer than you or I can remain solvent… The weak form EMH indicate that current asset prices reflect past price and volume information. Hence, the optimal outcome is achieved when marginal cost (MC) equals marginal benefit (MB). A semi-strong form efficient market would mean that neither fundamental or technical analysis could provide advantageous information, as all new information is instantly priced into the market. Semi-strong EMH believes that only those with privately held information could hold an advantage. The reason for this is that the price consumers are willing to pay for a product or service reflects the marginal utility they get from consuming the product. Economic efficiency is a relative term; an economy is more efficient when it produces more goods and services for society than another by using the same or lower input.

A market is called efficient when resources are used in a way that maximizes the production of goods and services at the lowest cost. Market efficiency is not only something that is important to economists but if you invest money then it is also something that might concern you too. Therefore, it is impossible for any investor in the long term to get returns substantially higher than the market average.

That is, any new information relevant to the market is spontaneously reflected in the stock prices. The empirical findings on Zimbabwe Stock Exchange (ZSE) weak-form efficiency since the 1993 stock market liberalisation have been mixed, indicating some changes in weak-form efficiency and its dependency on the tests and methodology used. However, in most cases, this requires some form of taxation. One could also argue that if the hypothesis is so weak, it should not be used in statistical models due to its lack of predictive behavior. Some Implications of Market Efficiency (continued) zIf financial markets are efficient, then there is no “best time” to purchase an asset. Allocative efficiency occurs when all goods and services within an economy are distributed according to consumer preferences. I conclude that our stock markets are more efficient and less predictable than many recent academic papers would have us believe. Table of Contents . A direct implication is that it is impossible to "beat the market" consistently on a risk-adjusted basis since market prices should only react to new information. The aim of this paper is twofold: first, it investigates the existence of the random walk hypothesis (RWH) by testing the weak-form efficiency in the returns of one of the largest stock markets in the Middle East and North Africa; the Saudi Stock Exchange (SSE), using a set of highly regarded parametric and nonparametric linear serial dependence tests. 3 Market efficiency should not be confused with the idea of efficient portfolios introduced in Chapter 8.

Weak-form of market efficiency postulates that past market date is fully reflected in the current market prices such that no rule derived from study of historical trends can be used to earn excess return. Stock market efficiency refers to the way stock prices reflect the available or private information in an efficient way. This theory implies that all available information is already reflected in stock prices. Efficient Market Hypothesis (EMH) Definition . Many empirical studies have confirmed the weak form of market efficiency in different capital markets.
