Pricing Rainbow Asian Options

The evaluation of rainbow options on two average prices (labeled as rainbow Asian options) is a computational problem arising from the inherent complexities of multifactor path-dependent options. In this article, the pricing model of rainbow Asian options on two dividend -paying assets was constructed on the basis of the Ito lemma and the arbitrage-free principle. With the boundary conditions, an analytical formula for the call option with geometric average was derived and also call-put parity relationship on the proposed option was provided. Overwhelming numerical evidence indicates that the reduction variate technique with the help of the above analytical solution dramatically improves the accuracy of the simulated price of rainbow Asian option with arithmetic average. Moreover, this study will pave a novel way to copy with the family of Asian options pricing.
