Essential Questions and Answers on Efficient Market Theory in "MISCELLANEOUS»UNFILED"
What is the Efficient Market Theory (EMT)?
The Efficient Market Theory (EMT) posits that all available information is reflected in the prices of traded assets, rendering it impossible for investors to consistently outperform the market.
What are the three levels of market efficiency?
EMT categorizes markets into three levels of efficiency:
- Weak-form: Only historical price data is considered, implying that technical analysis is ineffective.
- Semi-strong-form: All publicly available information is factored into prices, making it challenging for fundamental analysis to outperform the market.
- Strong-form: Even insider information is fully reflected in prices, precluding any possibility of informational advantage.

The EMT suggests that:
- Passive investing: Index funds and ETFs that track broad market indexes may be a more optimal strategy than active management.
- Diversification: Spreading investments across various asset classes and sectors can help minimize risk and maximize returns.
- Long-term investing: Focusing on long-term goals and employing a buy-and-hold strategy can mitigate short-term market fluctuations.

Critics argue that EMT:
- Assumptions: Reliance on perfect information and rational behavior, which may not always hold true in practice.
- Behavioral biases: Investors' emotional and irrational tendencies can deviate from market efficiency.
- Market anomalies: Certain market inefficiencies, such as the value premium or momentum, exist that contradict the theory.
