Under discrete-time GARCH models markets are incomplete so there is more than one price kernel for valuing contingent …-neutral dynamics of various classes of Generalized Hyperbolic GARCH models arising from different price kernels. We discuss the … neutral GARCH dynamics. Real data examples for pricing European options on the S&P 500 index emphasize the importance of the …

There is good empirical evidence to show that the financial series, whether stocks or indices, currencies or interest rates do not follow the log-normal random walk underlying the Black-Scholes model, which is the basis for most of the theory of options valuation. This article presents a...

Daily returns of financial assets are frequently found to exhibit positive autocorrelation at lag 1. When specifying a linear AR(l) conditional mean, one may ask how this predictability affects option prices. We investigate the dependence of option prices on autoregressive dynamics under...

In this paper we compare the price of an option with one year maturity of the German stock index DAX for several volatility models including long memory and leverage effects. We compute the price by applying a present value scheme as well as the Black-Scholes and Hull-White formulas which...

By extending the GARCH option pricing model of Duan (1995) to more flexible volatility estimation it is shown that the … properties of the stationary pricing distribution in the case of a threshold GARCH model. For a stock index series with a … pronounced leverage effect, simulated threshold GARCH option prices are substantially closer to observed market prices than the …

In this paper, we investigate the importance of different loss functions when estimating and evaluating option pricing models. Our analysis shows that it is important to take into account parameter uncertainty, since this leads to uncertainty in the predicted option price. We illustrate the...
