均值回归与状态切换下的最优VIX期货交易

文章 arXiv papers · 作者: Jiao Li

总结

本文使用均值回归VIX模型,对VIX期货的最优交易进行建模,模型动态取决于在有限状态集合间切换的市场状态。研究考察投资者何时入市和离市,并将参与的时机和顺序表示为最优双重停时问题。这些决策会产生相互耦合的变分不等式组。

为求解数值结果,作者采用带Crank–Nicolson格式的投影逐次超松弛法,并通过基于两状态马尔可夫链的示例展示最优交易边界。作者还考察交易成本和状态切换时机如何影响最终策略。摘录介绍了模型和数值方法,但未给出边界值、实证检验或实际交易表现。因此,结论仅涉及基于模型的示例;文中未证明该方法在实盘VIX期货数据或其他模型假设下的表现如何。

核心观点

  • 模型将VIX设为均值回归过程,其动态随切换状态而异。
  • 交易决策被表述为最优入场和离场时机问题。
  • 停时问题产生相互耦合的变分不等式。
  • 数值求解采用投影逐次超松弛法和Crank–Nicolson格式。
  • 数值示例考察了交易成本和状态切换时机,但未报告实盘交易结果。

# Trading VIX Futures under Mean Reversion with Regime Switching









This paper studies the optimal VIX futures trading problems under a regime-switching model. We consider the VIX as mean reversion dynamics with dependence on the regime that switches among a finite number of states. For the trading strategies, we analyze the timings and sequences of the investor's market participation, which leads to several corresponding coupled system of variational inequalities. The numerical approach is developed to solve these optimal double stopping problems by using projected-successive-over-relaxation (PSOR) method with Crank-Nicolson scheme. We illustrate the optimal boundaries via numerical examples of two-state Markov chain model. In particular, we examine the impacts of transaction costs and regime-switching timings on the VIX futures trading strategies.
