| Outline of Final Research Achievements |
Focusing on the so-called disposition effect observed in security markets as one of anomalous trading activities, through simulation studies we tried to find what mechanism causes the effect from behavioral point of views. The results of simulation studies show that, among behavioral properties of investors, the different risk tolerance has great influence on the cause of the effect. The risk aversion in the state of gains, however, does not play so significant role in causing the effect as expected. Rather, the risky attitude in the loss state is thought of as the most significant driving factor. This implies that the behavioral properties shown when investors are facing losses plays a key role in such an anomalous activity as the disposition effect.
