【Abstract】 The basic principle of the VaR model is analyzed and the behaviors of investors are simulated with the noise-signal,and then a kind of measure for the endogenous liquidity risk with the value-at-risk are obtained by establishing and using the VaR model to analyze one single stock.The model is also expanded and verified under the condition of investors with overconfidence.The theoretical reference to avoid risks for investors are provided.更多还原
