Study Notes
Market Efficiency
-
Semi-strong form efficiency: Current stock prices reflect all publicly available information. This includes company announcements, economic news, and political events. Strategies based on public information cannot generate abnormal profits. Stock prices rapidly incorporate new information, but not instantaneously. Fundamental analysis is ineffective under this form of efficiency. Large stock markets are largely semi-strong form efficient.
-
Strong form efficiency: Asset prices reflect all available information, both public and private. The market knows everything about securities, including unreleased information. Abnormal returns are impossible even from inside information. Corporate insiders lack an advantage for this reason. Professional fund managers often do not consistently outperform the overall market.
Market Efficiency Considerations
-
Market efficiency does not imply perfect stock pricing. Overvaluation and undervaluation of stocks are possible. Beating the market requires above-average information, analysis, or luck.
-
Criticisms of Efficient Market Hypothesis (EMH): Not included, but the text mentions this as a topic for review.
Weak Form Efficiency (not explicitly defined but inferred)
- If the weak-form were valid, stock prices would reflect all past price data.
Additional Notes
- Stock Price Determination: Not included in this specific section, but the text mentions this as a review topic.
- Investing/Financing: Not equivalent.
- Market Efficiency in General: The text presents arguments that stock markets are generally semi-strong form efficient; whether all markets are completely or always efficient is a subject of debate.
