Portfolio insurance allows investors to recover, at maturity, a given percentage of their initial invsetment. This limits downside risk in falling markets and allows some participation in rising markets. One of the standard portfolio insurance methods is the Constant Proportion Portfolio...

We consider the investor choice among standardized portfolios, which are based on cash, bond and stock indexes. We present the intertemporal optimization problem with commonly used utility functions. We provide a method to determine the optimal investor's choice, based on the knowledge of...

Purpose: Many insurance companies vigorously pursue top-line growth even though it has the potential to develop unprofitably over time. The time lag (or tail) between when insurance is sold and when claims are paid generates risks unique to insurance companies. Furthermore, the insurance market...
