Dynamic hedging of portfolio credit derivatives

Cont, Rama; Kan, Yu Hang - HAL - 2011

We compare the performance of various hedging strategies for index collateralized debt obligation (CDO) tranches across … a variety of models and hedging methods during the recent credit crisis. Our empirical analysis shows evidence for …-dimensional bottom-up models perform better than simpler top-down models. When it comes to hedging, top-down and regression-based hedging …
