Markets may remain difficult to beat, but investor crowding could create opportunities at extremes
The report noted that the stock market is vulnerable to a lack of diversity due to the social nature of investing
Morgan Stanley's research report suggests that distinguishing between efficient information incorporation and collective behavior-induced errors may become crucial for investors. While beating markets consistently remains challenging, extreme sentiment and valuations could signal when the market's wisdom is overwhelmed by crowd madness, according to the brokerage.
Markets typically aggregate information well, making it difficult for investors to beat prices consistently. However, unlike prediction or betting markets, stocks do not have a fixed accuracy date, leaving more room for narratives and sentiment to influence valuations. The report identifies three conditions for crowds to be collectively intelligent: cognitive diversity, effective aggregation, and appropriate incentives.
Stock markets are particularly vulnerable to losing diversity due to their social nature, as investors' behaviors become increasingly correlated, leading to bubbles and market extremes. Longer-term markets tend to converge to fundamental values, while shorter-term settings are prone to bubbles. Strong sentiment and extreme valuations can serve as indicators of potential crowd episodes.
Investors should exercise caution during periods of unusual consensus, as these may offer better insights into market extremes than assuming prices are always correct or always wrong.
