First, the action and state spaces were designed based on the characteristics of the hedging task, and a reward function was developed according to the cost function of the options. Second, combining the concept of curriculum learning, the agent was guided to adopt a simulated-to-real learning approach for dynamic hedging tasks, reducing the learning difficulty and addressing the issue of insufficient option data. A dynamic hedging strategy for 50ETF options was constructed. Finally, numerical experiments demonstrate the superiority of the designed algorithm over traditional hedging strategies in terms of hedging effectiveness.展开更多
基于上证50E T F和上证50E TF期权数据,本文经验研究了中国市场是否存在“定价核之谜”,并对“定价核之谜”与市场走势之间的关系进行了探讨。实证结果显示,中国市场存在“定价核之谜”,且“定价核之谜”与下期市场收益率呈显著负向关...基于上证50E T F和上证50E TF期权数据,本文经验研究了中国市场是否存在“定价核之谜”,并对“定价核之谜”与市场走势之间的关系进行了探讨。实证结果显示,中国市场存在“定价核之谜”,且“定价核之谜”与下期市场收益率呈显著负向关系、与下期市场振幅呈显著正向关系。本文首次给出了“定价核之谜”在中国金融市场存在的经验证据,并且证实了“定价核之谜”对下期市场走势具有一定的预测作用。展开更多
