1. Suppose the current daily volatilities of asset P and asset Q are 3% and 0.8%, respectively. The prices of the assets at close of trading yesterday were $20 and $10 and the estimate of the coefficient of correlation between the returns on the two assets made at this time was 0.65. Correlations and volatilities are updated using the GARCH(1,1) model. The estimates of the models parameters are =0.05 and =0.90. For the correlation =0.000001 and for the volatilities =0.000002. If the prices of the two assets at close of trading today are $19 and $9, how is the correlation estimate updated?
