This paper compares the option hedging and pricing performance of affine and non-affine stochastic volatility (SV) models with and without jumps in returns on a set of S\&P 500 option data from 2005 to 2009. The squared volatility index VIX serves as a proxy for the latent spot variance process, model parameter estimates of Christoffersen, Jacobs and Mimouni (2010) are used and all experiments are out-of-sample tests. The evaluation of hedging performance is based on the distribution of hedging errors and their dependency on the underlying for daily and weekly hedge rebalancing and different hedging strategies: delta, minimum-variance and delta-vega hedging. Pricing performance is mainly assessed based on implied volatility root mean squared errors, and both pricing and hedging error measures are decomposed along various dimensions. Monte Carlo methods are used to compute option sensitivities and prices and the theoretical backgrounds of the option pricing models and applied methodologies are outlined in detail. Different conclusions hold for the hedging (dynamic) and pricing (static) performance of the SV models investigated. For hedging, all SV models perform relatively similar, underperforming a simple ad-hoc Black-Scholes hedge for delta hedging, but with better results for minimum-variance and delta-vega hedging. No non-affine model is consistently better than the affine Heston (1993) model for hedging. Pricing errors suggest that a non-affine GARCH-type model with linear variance diffusion and drift specification performs best along virtually all dimensions, and that the VIX is a good proxy for its filtered spot variance path. Jumps have minor effects on pricing performance and virtually no effect on hedging performance for all models. Considering both hedging and pricing performance, advantages of the best performing non-affine model need to be considered in conjunction with its lack of analytical tractability that impose.

The paper examines alternative strategies for pricing and hedging options on German DAX-index. To this purpose an affine stochastic volatility model is estimated directly on objective probability system through a three step approach. Errors obtained by the implementation of the stochastic volatility model and Black and Scholes with different historical and implied volatility measures are compared and the performance is evaluated in terms of out-of-sample pricing and hedging. The results for DAX-index options market support the estimation on the affine stochastic volatility model in pricing as well as in hedging procedures.

Valuation and hedging of financial derivatives are intrinsically linked concepts. Choosing appropriate hedging techniques depends on both the type of derivative and assumptions placed on the underlying stochastic process. This volume provides a systematic treatment of hedging in incomplete markets. Mean-variance hedging under the risk-neutral measure is applied in the framework of exponential L(r)vy processes and for derivatives written on defaultable assets. It is discussed how to complete markets based upon stochastic volatility models via trading in both stocks and vanilla options. Exponential utility indifference pricing is explored via a duality with entropy minimization. Backward stochastic differential equations offer an alternative approach and are moreover applied to study markets with trading constraints including basis risk. A range of optimal martingale measures are discussed including the entropy, Esscher and minimal martingale measures. Quasi-symmetry properties of stochastic processes are deployed in the semi-static hedging of barrier options. This book is directed towards both graduate students and researchers in mathematical finance, and will also provide an orientation to applied mathematicians, financial economists and practitioners wishing to explore recent progress in this field."

Most term structure models with stochastic volatility are restrictive in that they assume the risk in derivative securities can be perfectly hedged by a portfolio consisting solely of bonds. Below, we demonstrate that this prediction fails in practice. In particular, we find that the changes in the term structure of swap rates have scant explanatory power for the returns of at-the-money straddles (long cap and floor). To account for this observation, we introduce a parsimonious Heath-Jarrow-Morton (1990) term structure model with stochastic volatility that is consistent with this empirical finding. Closed-form solutions are obtained for bond-options, and thus cap- and floor-prices. We then identify a general class of models with a generalized affine-structure that significantly expands the class studied by Duffie, Pan, and Singleton (2000). Some special cases are investigated, including an arbitrage-free model of a long-rate, similar in spirit to that proposed by Brennan and Schwartz (1979, 1982).
