Learning Module 3 Market Efficiency
50 questions available
Key Points
- Market efficiency: prices quickly reflect available information; trades incorporate news.
- Market value is the observed price; intrinsic value is the present value of expected cash flows.
- Discrepancies between market and intrinsic values create potential active investment opportunities.
- Market efficiency is affected by participants, disclosure, trading limits, liquidity, and costs.
- Prices may be efficient within arbitrage and cost bounds even if not perfectly equal to intrinsic value.
Key Points
- Weak-form efficiency: no excess profits from trading on past price/volume data; technical analysis challenged.
- Semi-strong efficiency: public information is quickly incorporated; event studies test this form.
- Strong-form efficiency: includes private information; generally not supported by evidence.
- Implication: passive management often outperforms active approaches after costs; fundamental analysis aids discovery.
Key Points
- Documented anomalies: January effect, momentum, size and value effects, IPO underpricing, earnings drift.
- Data-snooping, transaction costs, and risk adjustments often explain or reduce anomalies.
- Behavioral finance provides alternative explanations via investor biases (overconfidence, loss aversion, herding).
- Even if behavioral biases exist, costly or limited arbitrage may prevent persistent exploitable mispricing.
