| Abstract: | Based on the new policy of pursuing stock index futures,financing and securities loan,we applied t-EGARCH model and Copula Theory to open-end stock funds.The model can capture the nonlinearity between assets better and suit the market reality.Based on this model,we applied Monte Carlo simulation to the method of calculating the VaR of the top ten shares of Jingshun Growth Fund and the investment portfolio,thus confirming the validity of the method. |
