On the Performance of Asymptotic Locally Risk Minimizing Hedges in the Heston Stochastic Volatility Model
Ting, Sai Hung Marten - 2011
This paper investigates the use of the asymptotic Heston solution in locally risk minimizing hedging. The asymptotic Heston solution is presented along with issues that are relevant to its use. Comparison between the exact and asymptotic Heston hedges are made using both simulated and real...
