具有因子模型和随机控制的高维统计套利

High-dimensional statistical arbitrage with factor models and stochastic control

Jorge Guijarro-Ordonez

摘要:

本文提供了一种对高维统计套利的研究,将因子模型与随机控制工具相结合,获得了在高维环境中既可解释又可计算实现的封闭形式的最优策略。我们的设置是基于一个一般的解析构造的因子模型与均值回复残差,在其中,我们展示了如何构建解析市场中性的投资组合,我们分析的问题,在连续时间和有限的地平线下,指数和均值方差效用的最佳投资。我们还扩展了我们的模型,将约束投资者的投资组合,如美元中性和市场摩擦的形式,临时二次交易成本,提供广泛的蒙特卡罗模拟以前的战略与100个资产,并描述进一步可能的扩展我们的工作。

英文摘要:

The present paper provides a study of high-dimensional statistical arbitrage that combines factor models with the tools from stochastic control, obtaining closed-form optimal strategies which are both interpretable and computationally implementable in a high-dimensional setting. Our setup is based on a general statistically-constructed factor model with mean-reverting residuals, in which we show how to construct analytically market-neutral portfolios and we analyze the problem of investing optimally in continuous time and finite horizon under exponential and mean-variance utilities. We also extend our model to incorporate constraints on the investor's portfolio like dollar-neutrality and market frictions in the form of temporary quadratic transaction costs, provide extensive Monte Carlo simulations of the previous strategies with 100 assets, and describe further possible extensions of our work.
