The simplest of these payoffs, like those for a call spread or a strangle, for example, can be constructed out of a straightforward combination of plain vanilla puts and calls. This leads to very easy formulas for pricing and hedging them, but the possible payoff patterns invariably consist of a collection of linear segments defined by the intervals between the strikes of the options in the set. This article provides a way to significantly extend the achievable payoff patterns to any polynomial function of the final asset price. The building block is no longer a plain vanilla option, but a power option, the payoff of which is a function of (Sa - X) for some exponent a. The authors first show how to price such options under several important price processes, including Heston-style stochastic volatility and a general Lévy process. They then derive the formula for an option with a general polynomial payoff, as a function of power options. Finally, they offer some examples to illustrate the technique, including parabolic payoff call options.TOPICS: Options, statistical methods
