用于时间序列动量与头寸规模管理的深度神经网络

文章 arXiv papers · 作者: Bryan Lim et al.

总结

论文介绍深度动量网络,将深度学习与时间序列动量中使用的波动率缩放框架相结合。神经网络联合学习趋势估计和头寸规模,其参数经过训练以优化信号的夏普比率。这样就无需再手动分别指定这些组成部分。

对 88 个连续期货合约的回测报告称,基于 LSTM 的版本在不计交易成本时,夏普比率超过传统方法的两倍;即使成本高达 2–3 个基点,表现仍然更优。作者还加入换手率正则化,使训练能够考虑交易成本,包括流动性较低资产的交易成本。证据仅限于报告的回测;摘要未说明评估期、基准详情,也未说明结果是否适用于测试合约和成本假设以外的情形。

核心观点

  • 网络在波动率缩放的动量框架内联合学习趋势估计和头寸规模。
  • 训练过程直接优化最终交易信号的夏普比率。
  • 对 88 个连续期货合约的回测报告称,夏普比率较传统方法有所提高。
  • 加入换手率正则化项后,模型可以在训练期间考虑交易成本。

# Enhancing Time Series Momentum Strategies Using Deep Neural Networks









While time series momentum is a well-studied phenomenon in finance, common strategies require the explicit definition of both a trend estimator and a position sizing rule. In this paper, we introduce Deep Momentum Networks -- a hybrid approach which injects deep learning based trading rules into the volatility scaling framework of time series momentum. The model also simultaneously learns both trend estimation and position sizing in a data-driven manner, with networks directly trained by optimising the Sharpe ratio of the signal. Backtesting on a portfolio of 88 continuous futures contracts, we demonstrate that the Sharpe-optimised LSTM improved traditional methods by more than two times in the absence of transactions costs, and continue outperforming when considering transaction costs up to 2-3 basis points. To account for more illiquid assets, we also propose a turnover regularisation term which trains the network to factor in costs at run-time.
