Abstract
Without market assumptions,Mogens Bladt and Tina Hviid Rydberg use merely probability measure of price process and actuarial considerations for pricing options.Based on their study and using the method of actuarial pricing,this paper obtains Asian option pricing formula when underlying assets are driven by fractional Brownian motion.And the paper concludes that the geometric Brownian motion is a special case of fractional Brownian motion.Then the classical model of option pricing can be generalized based on fractional Brownian motion.
