A »The Efficient Market Hypothesis (EMH) posits that asset prices fully reflect all available information. It has three forms: the weak form, which asserts that prices incorporate historical data; the semi-strong form, which claims prices adjust to publicly available new information; and the strong form, which suggests prices reflect even insider information. EMH implies that consistently outperforming the market is challenging without taking on higher risk.

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 (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, it supports the semi-strong form of EMH.

A »The Efficient Market Hypothesis (EMH) posits that asset prices reflect all available information, making it impossible to consistently outperform the market. Its three forms are: the weak form, where prices reflect past market data; the semi-strong form, where prices reflect all public information; and the strong form, where prices reflect all information, public and private, implying no advantage from insider knowledge.

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 reflected), semi-strong (public information reflected), and strong (all information, public and private, reflected), each representing a different level of market efficiency.

A »The Efficient Market Hypothesis (EMH) posits that asset prices fully reflect all available information. Its three forms include the weak form, where prices reflect past market data; the semi-strong form, where prices adjust to publicly available new information; and the strong form, where prices account for all information, public and private. For example, if EMH holds, consistently beating the market through stock analysis is impossible.
