A »The Efficient Market Hypothesis (EMH) posits that financial markets fully reflect all available information, making it impossible to consistently achieve higher returns than average. It has three forms: weak form, where all past market data is reflected; semi-strong form, where all public information is reflected; and strong form, where all information, public and private, is reflected in asset prices.

A »The Efficient Market Hypothesis (EMH) posits that financial markets reflect all available information, making it impossible to consistently achieve abnormal returns. It has three forms: weak (past prices are reflected), semi-strong (all public information is reflected), and strong (all information, public and private, is reflected).

A »The efficient market hypothesis (EMH) posits that asset prices fully reflect all available information, making it impossible to consistently achieve higher returns. Its three forms are: weak (prices reflect past data), semi-strong (prices reflect public information), and strong (prices reflect all information, public and private). For example, if EMH holds, insider information would not offer an advantage in stock trading, as prices already adjust accordingly.

A »The Efficient Market Hypothesis (EMH) states that financial markets reflect all available information. It has three forms: weak (past prices are reflected), semi-strong (all public information is reflected), and strong (all information, public and private, is reflected), each representing a different level of market efficiency.

A »The Efficient Market Hypothesis (EMH) suggests that asset prices fully reflect all available information. It has three forms: weak, which implies past prices can't predict future prices; semi-strong, which asserts that all publicly available information is reflected in stock prices; and strong, which claims even insider information is accounted for. EMH challenges active trading strategies, suggesting they cannot consistently outperform market indices.

It has three forms: weak (past prices are reflected), semi-strong (all public information is reflected), and strong (all information, public and private, is reflected). For example, if a company's stock price immediately adjusts to new earnings data, the semi-strong form holds.

A »The efficient market hypothesis (EMH) posits that asset prices fully reflect all available information, making it impossible to consistently achieve higher returns than average market performance. It has three forms: weak (prices reflect past data), semi-strong (prices incorporate all public information), and strong (prices include all public and private data). EMH suggests that beating the market is largely about luck, not skill.

A »The Efficient Market Hypothesis (EMH) states that financial markets reflect all available information. It has three forms: weak (past prices are reflected), semi-strong (all public information is reflected), and strong (all information, public and private, is reflected). These forms vary in the extent of information assumed to be incorporated into market prices.

A »The Efficient Market Hypothesis (EMH) posits that financial markets reflect all available information. It has three forms: weak (prices reflect past data), semi-strong (prices reflect all public information), and strong (prices reflect all public and private information). For example, in a semi-strong market, stock prices would instantly adjust to news, making it futile to outperform the market through publicly available information alone.
