What is the Efficient Market Hypothesis (EMH) and what are its implications for investors? The EMH states that financial markets are informationally efficient, meaning that asset prices fully reflect all available information. This theory suggests that it's impossible to consistently outperform the market through stock selection or market timing. The EMH is typically divided into three forms: weak, semi- strong, and strong. Each form makes progressively stronger claims about the efficiency of markets and the type of information reflected in prices. If the EMH holds true, what does this mean for active investment strategies? How does the EMH challenge the concept of value investing?

states that financial markets are informationally
efficient, meaning that asset prices fully reflect all
available information. This theory suggests that it's
impossible to consistently outperform the market
through stock selection or market timing. The EMH
is typically divided into three forms: weak, semi-
strong, and strong. Each form makes progressively
stronger claims about the efficiency of markets and

EMH holds true, what does this mean for active
investment strategies? How does the EMH
