基于深度神经网络的有效套期保值前沿

The Efficient Hedging Frontier with Deep Neural Networks

Zheng Gong, Carmine Ventre, John O'Hara

摘要:

风险和收益之间的权衡产生了在金融中很好理解的多标准优化问题,有效前沿是导航其最优解集的工具。受深度神经网络在市场摩擦时对冲普通期权方面的最新进展的启发,我们引入了有效对冲边界(EHF),通过过滤步骤丰富管道,允许权衡成本和风险。通过这种方式,交易者的风险偏好与前沿的预期对冲成本相匹配,并且可以使用深度神经网络计算相应的对冲策略。我们进一步发展我们的框架,以改善EHF,并找到更好的对冲策略。通过在管道中添加随机森林分类器来预测市场走势,我们展示了前沿如何向更低的成本和更低的风险转移,这表明整体对冲性能有所改善。此外,通过设计一个新的递归神经网络,我们还发现了对冲成本更低的前沿策略。

英文摘要:

The trade off between risks and returns gives rise to multi-criteria optimisation problems that are well understood in finance, efficient frontiers being the tool to navigate their set of optimal solutions. Motivated by the recent advances in the use of deep neural networks in the context of hedging vanilla options when markets have frictions, we introduce the Efficient Hedging Frontier (EHF) by enriching the pipeline with a filtering step that allows to trade off costs and risks. This way, a trader's risk preference is matched with an expected hedging cost on the frontier, and the corresponding hedging strategy can be computed with a deep neural network. We further develop our framework to improve the EHF and find better hedging strategies. By adding a random forest classifier to the pipeline to forecast market movements, we show how the frontier shifts towards lower costs and reduced risks, which indicates that the overall hedging performances have improved. In addition, by designing a new recurrent neural network, we also find strategies on the frontier where hedging costs are even lower.
