在金融衍生品交易中，管理波动率风险对保护投资组合至关重要。传统基于规则的希腊值对冲策略难以适应快速变化的市场。本文提出一种动态希腊值对冲新框架——自适应Nesterov加速分布强化深度对冲（ANADDH），将分布强化学习与定制化的自适应Nesterov加速设计相结合。该方法通过建模对冲效率的分布，在复杂金融环境中提升学习性能，实现更精准、响应更快的对冲策略。自适应Nesterov加速通过动态调整梯度动量，显著增强模型的稳定性与收敛速度。实证分析表明，该方法在多种市场条件下均显著优于现有对冲技术。结果验证了分布强化学习与先进优化技术融合在金融风险管理中的有效性，凸显了深度神经网络在金融领域的实际应用价值。
原文摘要 · Abstract (English)
In the field of financial derivatives trading, managing volatility risk is crucial for protecting investment portfolios from market changes. Traditional Vega hedging strategies, which often rely on basic and rule-based models, are hard to adapt well to rapidly changing market conditions. We introduce a new framework for dynamic Vega hedging, the Adaptive Nesterov Accelerated Distributional Deep Hedging (ANADDH), which combines distributional reinforcement learning with a tailored design based on adaptive Nesterov acceleration. This approach improves the learning process in complex financial environments by modeling the hedging efficiency distribution, providing a more accurate and responsive hedging strategy. The design of adaptive Nesterov acceleration refines gradient momentum adjustments, significantly enhancing the stability and speed of convergence of the model. Through empirical analysis and comparisons, our method demonstrates substantial performance gains over existing hedging techniques. Our results confirm that this innovative combination of distributional reinforcement learning with the proposed optimization techniques improves financial risk management and highlights the practical benefits of implementing advanced neural network architectures in the finance sector.
