8 Conclusions<br />
We described an operator splitting method for solving linear complementarity<br />
problems (LCPs) resulting from American option pricing problems. We<br />
considered it in the case of the Black–Scholes model, Kou’s jump-diffusion<br />
model, <strong>and</strong> Heston’s stochastic volatility model for the value of the underlying<br />
asset. The numerical results demonstrated that with all these models the<br />
prices can be computed in a few milliseconds on a PC.<br />
As future research one could consider the construction of adaptive discretization;<br />
see [AP05, LPvST07], for example. Also the robustness <strong>and</strong> accuracy<br />
of discretizations for Heston’s model with higher correlations could be<br />
studied. A natural generalization would be to extent the methods for stochastic<br />
volatility models including jumps like the ones in [Bat96, DPS00].<br />
