The Story in Brief
A Morgan Stanley research report, as reported by The Hindu Business Line, warns that while stock markets generally do a good job of aggregating information and making prices hard to beat consistently, extreme sentiment, sharp price moves and elevated valuations could signal a breakdown into 'crowd madness'. The report identifies three conditions for collective intelligence: cognitive diversity, effective aggregation and appropriate incentives.
Stock markets are particularly vulnerable to a breakdown in diversity because investing is social, leading to correlated behaviour that can cause booms and busts. Longer investor horizons tend to converge towards fundamental value, while shorter horizons are more prone to bubbles. For investors, periods of unusually strong consensus deserve extra scrutiny rather than routine acceptance of market prices.
The Indian Opinion
Two lazy narratives often shape market talk: that prices are always right, or that the market is a casino. Morgan Stanley's report points to a middle ground: markets work until they don't, and the trick is spotting when diversity breaks down. For the average Indian investor, the temptation to follow the herd is strongest during rallies. Watch for extreme valuations or unusually one-sided sentiment as real-world tests of whether crowd wisdom has turned into noise.
