Review Questions

• How does Andrew Lo's Adaptive Markets Hypothesis differ from the traditional Efficient Market Hypothesis?
  • Andrew Lo's Adaptive Markets Hypothesis differs from the Efficient Market Hypothesis by suggesting that markets are not always efficient and are influenced by human behavior. While the Efficient Market Hypothesis posits that asset prices reflect all available information, Lo argues that investors adapt their strategies based on past experiences and changing market conditions. This means that market efficiency can vary over time and is affected by psychological factors, leading to potential mispricing and anomalies.
