A Nonparametric Approach to Pricing and Hedging Derivative Securities Via Learning Networks
提出用学习网络非参数估计衍生品定价公式，模拟显示可从两年期权价格训练集恢复Black-Scholes公式，并成功用于S&P 500期货期权的定价与delta对冲。
We propose a nonparametric method for estimating the pricing formula of a derivative asset using learning networks.Although not a substitute for the more traditional arbitrage-based pricing formulas, network pricing formulas may be more accurate and computationally more e cient alternatives when the underlying asset's price dynamics are unknown, or when the pricing equation associated with no-arbitrage condition cannot be solved analytically.T o assess the potential value of network pricing formulas, we simulate Black-Scholes option prices and show that learning networks can recover the Black-Scholes formula from a two-year training set of daily options prices, and that the resulting network formula can be used successfully to both price and delta-hedge options out-of-sample.For comparison, we estimate models using four popular methods: ordinary least squares, radial basis function networks, multilayer perceptron networks, and projection pursuit.To illustrate the practical relevance of our network pricing approach, we apply it to the pricing and delta-hedging of S&P 500 futures options from 1987 to 1991.
