Using daily options prices on the Eurostoxx 50 stock index over the whole year 2008, we compare the performance of three popular stochastic volatility models (Heston, 1993; Bates, 1996; Heston and Nandi, 2'007, in addition to the traditional Black-Scholes model and a proprietary trading desk model.

Using daily options prices on the Eurostoxx 50 stock index over the whole year 2008, we compare the performance of three popular Stochastic Volatility (SV) models (Heston, 1993; Bates, 1996; Heston and Nandi, 2000), in addition to the traditional Black-Scholes model and a proprietary trading desk model....

In this paper, we investigate liquidity supply and demand around price jumps in a pure order driven stock market using a detailed tick frequency data set on the Euronext 100 index. The advantage of this database is to allow us to disentangle two major evolutions in European financial markets:...
