Options on constant proportion portfolio insurance with guaranteed minimum equity exposure
In the present paper we study a new exotic option offering participation in a dynamic asset allocation strategy, which is an extension of the well-known Constant Proportion Portfolio Insurance (CPPI) strategy. Our novel approach consists in assuming that the percentage of wealth invested in stocks cannot go under a fixed level, called guaranteed minimum equity exposure (GMEE). In particular, our proposal ensures to overcome the so-called cash-in risk, typically related to a standard CPPI technique, simultaneously guaranteeing the equity market participation.
