摘要:

我们研究神经网络作为非参数估计工具的期权套期保值。为此,我们设计了一个名为HedgeNet的网络,它直接输出对冲策略。该网络被训练为最小化对冲误差而不是定价误差。应用于标准普尔500指数和欧洲斯托克50指数期权的收盘价和报价,该网络能够显著降低Black-Scholes基准的均方对冲误差。然而,一个类似的好处出现了简单的线性回归,包括杠杆效应。

英文摘要:

We study neural networks as nonparametric estimation tools for the hedging of options. To this end, we design a network, named HedgeNet, that directly outputs a hedging strategy. This network is trained to minimise the hedging error instead of the pricing error. Applied to end-of-day and tick prices of S&P 500 and Euro Stoxx 50 options, the network is able to reduce the mean squared hedging error of the Black-Scholes benchmark significantly. However, a similar benefit arises by simple linear regressions that incorporate the leverage effect.
