We present a parallel algorithm that computes the ask and bid prices of an American option when proportional transaction costs apply to the trading of the underlying asset. The algorithm computes the prices on recombining binomial trees, and is designed for modern multi-core processors. Although parallel option pricing has been well studied, none of the(More)
In the paper by Melnikov and Petrachenko 'On option pricing in binomial market with transaction costs,' Finance Stoch. 9 (2005), 141–149, a procedure is put forward for pricing and replicating an arbitrary European contingent claim in the binomial model with bid-ask spreads. We present a counterexample to show that the option pricing formula stated in that(More)
