Portfolio insurance with ratcheted floor as a long-term asset management strategy: implications of loss aversion

摘要

The existing literature has revealed that the performance of current portfolio insurance strategies as long-term asset management is limited. Prospect theory implies that creation of ladder return distributions by portfolio insurance can improve long-term asset management with criteria of loss avoidance and gain protection. Based on this principle, we propose the Ratcheted Floor Variable Proportion Portfolio Insurance (RF-VPPI) as a competing strategy with the Constant Proportion Portfolio Insurance (CPPI) and rolling-CPPI strategies. Simulations and empirical tests demonstrate that the RF-VPPI outperforms the CPPI and the rolling-CPPI in the long term.
