Empirical pricing kernels obtained from the UK index options market

Empirical Pricing Kernels and Investor Preferences

This paper analyzes empirical market utility functions and pricing kernels derived from the DAX and DAX option data for three market regimes. A consistent parametric framework of stochastic volatility is used. All empirical market utility functions show a region of risk proclivity that is reproduced by adopting the hypothesis of heterogeneous individual investors whose utility functions have a ...

Pricing and Informational E ffi ciency of the MIB 30 Index Options Market .

We analyze the pricing and informational efficiency of the Italian market for options written on the most important stock index, the MIB30. We find several indications inconsistent with the hypothesis that the Italian MIBO is an efficient market. We report that a striking percentage of the data consists of option prices violating basic no-arbitrage conditions. This percentage declines but never...

Pricing of Index Options under a Minimal Market Model with Lognormal Scaling

Pricing of index options under a minimal market model with log-normal scaling

This paper describes a two-factor model for a diversified market index using the growth optimal portfolio with a stochastic and possibly correlated intrinsic timescale. The index is modelled using a time transformed squared Bessel process with a log-normal scaling factor for the time transformation. A consistent pricing and hedging framework is established by using the benchmark approach. Here ...

Pricing and Informational Efficiency of the MIB30 Index Options

We report that a striking percentage of the data consists of option prices violating basic no-arbitrage conditions. This percentage declines when we relax the no-arbitrage restrictions to accommodate for the presence of bid/ask spreads and other frictions, ...
