%X The price of basket options can be represented as an exact analytical part and an approximate part by using a conditional variable. The first part is calculated by conditioning on the price process of the underlying asset, and the second part is calculated by a moment-matching approach. In order to calculate the second part, the authors find a new single random variable, which has an analytically known distribution, to approximate the sum of log-normal random variables and to obtain a closed-form pricing formula. Their method can be viewed as a combination of conditioning and moment-matching methods. Numerical studies have demonstrated that their formula is more accurate in handling both homogeneous and heterogeneous lognormal random variable cases.TOPICS: Derivatives, optionsKey Findings• The price of basket options can be represented as an exact analytical part and an approximate part by using a conditional variable.
