Study Notes
Objectives of Market Efficiency
- Improve investment performance by understanding and leveraging market efficiency.
- Learn how market participants process information, integrating it into asset prices.
- Explore the implications and significance of the Efficient Market Hypothesis (EMH).
- Acquire testing methodologies for different forms of market efficiency.
Efficient Market Hypothesis (EMH) Forms
- Weak Form: Prices reflect historical trading data (past prices, volumes).
- Semi-Strong Form: Prices reflect all public information (fundamental data, analyst forecasts).
- Strong Form: Prices reflect all information, including non-public information (future product launches).
Reasons for Financial Market Efficiency
- Traders can rapidly arbitrage inefficiencies, minimizing potential losses.
- Professional traders quickly obtain and act on information.
- Numerous investors operate in a competitive environment, enhancing efficiency.
- Active, liquid trading conditions support market efficiency.
Arbitrage Explained
- Arbitrage occurs when investors buy undervalued stocks, driving prices to align with asset value.
- Price corrections happen when mispriced assets are identified and traded effectively.
Testing Market Efficiency
- Direct Tests: Challenging due to the non-observable "true" asset value.
- Indirect Tests: Market inefficiencies can be explained by factors such as risk and transaction costs.
- Observations like CAPM limitations and the slow reaction of prices in some markets may indicate inefficiencies.
Risk Factors
- Small-Firm Effect: Smaller companies tend to outperform larger ones.
- Book-to-Market Effect: Companies with higher book-to-market ratios yield greater returns than those with lower ratios.
Arguments Against Market Efficiency
- Information dissemination involves costs and time delays.
- Change in stock return probability distributions can skew results.
- Perceptual biases in investors, such as loss aversion or overconfidence, create inefficiencies.
- Behavioral finance plays a role in market behavior and decision-making.
Tests of the Efficient Market Hypothesis (EMH)
- Analyzed S&P 500 returns from 1950-2022 indicate minimal relationship between unlagged and lagged monthly returns.
- Conclusions drawn show weak explanatory power of prior returns on subsequent returns.
Investor Attention and Market Behavior
- Media coverage can impact stock returns; stocks with less media attention often yield higher returns.
- Days of distracted trading show decreased liquidity and increased volatility.
Construction of the FEARS Index
- Measures investor sentiment using Google Trends search volume on sentiment-relevant terms.
- Identifies trends to analyze the impact of sentiment on market volatility and returns.
FEARS Index Results
- Positive correlation between FEARS Index and market volatility indicates sentiment can lead to temporary mispricing.
- Negative correlation exists between FEARS Index and stock returns on the same day, suggesting shifts in fund flow behaviors.
Market Anomalies and Predictability
- Literature identifies equity anomalies that purportedly predict market returns.
- Examination of predictability through machine learning shows comprehensive testing of these anomalies is necessary.
