Abstract: The disposition effect is a typical phenomenon in the stock investment. It refers to the tendency to sell assets that have gained value(winners)and to keep assets that have lost value(losers). Since concept of disposition effect was posed, researchers have explored the psychological mechanisms. They have found that the prospect theory, cognitive dissonance theory, overconfidence theory and regret theory can explain the causes of disposition effect. The prospect theory indicates investors are risk-aversion in the domain of gains and risk-seeking in the domain of losses. So they sell winners and hold losers. At the other hand, some researchers take cognitive dissonance theory to explain the disposition effect. Regret theory reveal the disposition effect is the result of pursuing pride and regret-aversion. At last, overconfidence theory illustrates the cause of disposition effect by bias that people always overestimate accuracy of prediction of the price of stock. Finally, this paper identifies the problems and suggests the direction of development on disposition effect in the future.
