荔园学者Colloquium第三十期

讲座题目:Dynamic Trading with Realization Utility

主讲人：戴民 教授（香港理工大学）

讲座时间：2023年6月19日10：00-11：00

讲座地点：深圳大学粤海校区国际会议厅大厅

内容概述：We develop a model where a realization-utility agent can simultaneously invest in a risky asset and a risk-free asset. By saving in the risk-free asset the agent makes smaller trades at higher frequencies, spreading out his trades over time to reduce the downside risk. By using leverage, the agent trades larger than his budget and is thus more reluctant to realize losses. While leverage strengthens the disposition effect, imposing leverage constraints mitigates it. Our model generates a voluntary realization of deep losses, because of the interaction between downward asset-price jumps and the option to save in the risky asset. Our model predictions are consistent with empirical evidence. This work is joint with Cong Qin and Neng Wang.
