Abstract: Herding and contrarian strategies in financial markets produce informational inefficiencies because investors ignore private information, instead following or bucking past trends. In a simple trading environment, I demonstrate theoretically that investors with prospect theory preferences ignore private information by following a strategy that looks like herding or contrarianism, but which is actually trend-independent. I confirm the theory's predictions in a laboratory experiment designed to rule out other sources of these behaviors, and find that approximately 70% of subjects exhibit herd-like behavior. Finally, I perform a calibration exercise using actual market data to demonstrate the applicability of the results to more general settings
