摘要:

本文提出了一种期权深度delta对冲框架,利用神经网络学习对冲函数与隐含Black-Scholes delta之间的残差。该方法利用这些残差更平滑的特性,提升了深度学习性能。利用十年的每日S&P 500指数期权数据,我们的实证分析表明,以均方单步对冲误差作为损失函数来学习残差,相比直接学习对冲函数显著提升了对冲性能,通常提升超过100%。在学习残差时增加输入特征对看跌期权的对冲性能提升大于看涨期权,而市场情绪的影响较小。此外,用三年数据学习残差即可达到用十年数据直接学习的对冲性能,证明我们的方法所需数据更少。

英文摘要:

This paper proposes a deep delta hedging framework for options, utilizing neural networks to learn the residuals between the hedging function and the implied Black-Scholes delta. This approach leverages the smoother properties of these residuals, enhancing deep learning performance. Utilizing ten years of daily S&P 500 index option data, our empirical analysis demonstrates that learning the residuals, using the mean squared one-step hedging error as the loss function, significantly improves hedging performance over directly learning the hedging function, often by more than 100%. Adding input features when learning the residuals enhances hedging performance more for puts than calls, with market sentiment being less crucial. Furthermore, learning the residuals with three years of data matches the hedging performance of directly learning with ten years of data, proving that our method demands less data.
