The classical APT model is of the form r j - E(r j) = beta j(I - EI) + epsilon j, where r j - E(r j) is the earning deviation (called basic ariance-profit) of the security j, I is a common factor.

A fast method is developed for value-at-risk and expected shortfall prediction for univariate asset return time series exhibiting leptokurtosis, asymmetry and conditional heteroskedasticity. It is based on a GARCH-type process driven by noncentral t innovations. While the method involves the use...
