investor psychology

Investor psychology systematically undermines rational financial behavior at both the individual and crowd level. When fund managers are compensated on assets under management rather than returns, the structure incentivizes excessive trading—even though the mathematics clearly favor patient, long-term holding that minimizes tax drag and maximizes compounding. At the group level, the same psychological tendencies that make people uncomfortable with inaction also make them susceptible to fraud: investor eagerness signals danger rather than opportunity, and consistent reported returns create social proof that feeds Ponzi-like schemes long past their mathematical expiration date. The underlying lesson is that what feels like diligence—trading frequently, chasing hot opportunities, trusting momentum—is often the opposite of what produces wealth, while what feels like passivity—holding great businesses, waiting, skepticism toward too-good-to-be-true returns—is frequently the rational action disguised as inaction.
