最优趋势跟踪投资组合

Optimal trend following portfolios

Sebastien Valeyre

AI总结:

本文构建含趋势协方差矩阵与风险溢价的统一理论模型,推导基于趋势跟踪信号的最优投资组合,并通过跨资产回测验证其超额收益。

摘要:

本文推导了一个基于趋势跟踪信号的最优投资组合。在早期相关文章的基础上,本文提供了一个统一的理论框架,用以引入包含趋势协方差矩阵和风险溢价的自相关模型。我们为趋势协方差矩阵设定了具有实际意义的模型。最优投资组合被分解为四个基本组成部分,从而产生四种基本投资组合:Markowitz、风险平价、不可知风险平价,以及基于风险平价的趋势跟踪。将所提出的最优投资组合应用于跨资产交易范围,其超额表现通过实证回测得到确认。因此,我们提供了一个统一框架,用以描述并合理解释早期开发的投资组合。

英文摘要:

This paper derives an optimal portfolio that is based on trend-following signal. Building on an earlier related article, it provides a unifying theoretical setting to introduce an autocorrelation model with the covariance matrix of trends and risk premia. We specify practically relevant models for the covariance matrix of trends. The optimal portfolio is decomposed into four basic components that yield four basic portfolios: Markowitz, risk parity, agnostic risk parity, and trend following on risk parity. The overperformance of the proposed optimal portfolio, applied to cross-asset trading universe, is confirmed by empirical backtests. We provide thus a unifying framework to describe and rationalize earlier developed portfolios.
