What Is the Efficient Market Hypothesis?
The gist of EMH is that the prices of assets, such as stocks, reflect all available information about them. Which is a reason why " insider trading " is a crime - people with information not available to the general investing public have a distinct advantage over other investors.
The Three Main Variants of Efficient Markets Hypothesis
Weak Form Efficiency: The basis of "weak form efficiency" is, as the qualifying phrase to all investors by advisers always suggests: "past performance is no guarantee of future results." In other words, future prices cannot be predicted merely by reviewing past prices.
Positives and Negatives of EMH
Problems with the idea of Efficient Markets cited by critics lie in the area of behavioral science. First, individuals view market information differently. Second, markets as a whole can be sent into a "panic," based on no fundamental reason other than fear.
What Is Efficient Market Hypothesis?
The Efficient Market Hypothesis (EMH) essentially says that all known information about investment securities, such as stocks, is already factored into the prices of those securities. If that is true, no amount of analysis can give you an edge over "the market."
What Are the Types of EMH?
There are three forms of EMH: weak, semi-strong, and strong. Here's what each says about the market.
EMH and Investing Strategies
Proponents of EMH, even in its weak form, often invest in index funds or certain ETFs. That is because those funds are passively managed and simply attempt to match, not beat, overall market returns.
The Bottom Line
If you believe that you can't predict the stock market, you would most often support the EMH. But a short-term trader might reject the ideas put forth by EMH, because they believe that they are able to predict changes in stock prices.
Frequently Asked Questions (FAQs)
At the core of EMH is the theory that, in general, even professional traders are unable to beat the market in the long term with fundamental or technical analysis. That idea has roots in the 19th century and the "random walk" stock theory.
Key Takeaways
The efficient market hypothesis posits that the market cannot be beaten because it incorporates all important information into current share prices, so stocks trade at the fairest value.
Weak Form
The three versions of the efficient market hypothesis are varying degrees of the same basic theory. The weak form suggests that today’s stock prices reflect all the data of past prices and that no form of technical analysis can be effectively utilized to aid investors in making trading decisions.
Semi-Strong Form
The semi-strong form efficiency theory follows the belief that because all information that is public is used in the calculation of a stock's current price, investors cannot utilize either technical or fundamental analysis to gain higher returns in the market.
Strong Form
The strong form version of the efficient market hypothesis states that all information—both the information available to the public and any information not publicly known—is completely accounted for in current stock prices, and there is no type of information that can give an investor an advantage on the market.
Anomalies
There are anomalies that the efficient market theory cannot explain and that may even flatly contradict the theory. For example, the price/earnings (P/E) ratio shows that firms trading at lower P/E multiples are often responsible for generating higher returns.

History and Assumptions
The theory is credited to economist Eugene Fama, who in the 1960s developed it from a Ph.D. dissertation. Fama’s research can be found in his 1970 book, titled – Efficient Capital Markets: A Review of Theory and Empirical Work.
Efficient Market Hypothesis – What it Says?
The theory states that at any given point in time, a stock price reflects all available information that is publicly available. Or, we can say, the theory says that a stock trades at fair value all the time. Basically, the theory implies that beating the market return is more of a chance than selecting the right stocks by doing research.
Efficient Market Hypothesis Criticism
Though there are many who support the theory, a few exceptions to the theory exist. The biggest exception is legendary investor Warren Buffett, who has always beaten the market returns in the long term. Others who consistently generate above-market returns are Paul Tudor Jones, John Templeton, and Peter Lynch.
Forms of Efficient Market Hypothesis
It assumes that the stock price includes all information publicly available, and not the information that is not yet publicly available. Also, it assumes the past price, volume, and returns information is unrelated to future prices.
What Passive and Actives Investors Do?
Those who believe in the EMH or the passive investors can go for the index funds or certain ETFs. Such financial options are managed passively, which means their objective is not to beat the overall market returns. Such an investment strategy also aligns with a common saying “if you can’t beat them, join them.”
Final Words
There have been several studies that support the EMH, such as a long-term study by Morningstar. Such studies and the proponents of EMH have led to the rise in the popularity of the funds that try to mirror major indexes.
