趋势跟踪、长期方差与尾部保护

文章 arXiv papers · 作者: Tung-Lam Dao et al.

总结

本文通过长期与短期已实现方差的差异解释趋势跟踪。文中指出,这种关系适用于多种趋势策略定义,并有助于解释综合CTA表现的正凸性。作者认为,采用适当方法衡量时,这种凸性更强,但描述未提供可用于评估该主张的数据、测量细节或数值结果。

文章还将趋势策略与风险平价投资组合联系起来,并提出一个宽跨式期权组合,旨在隔离对标的资产长期方差的敞口。宽跨式期权组合的构造提供了另一种考察趋势与波动率关系的方式。摘要没有说明实施选择、市场覆盖范围、成本或实证局限,因此呈现的是概念性概述,而非实际交易评估。

核心观点

  • 趋势策略表现与长期和短期已实现方差之差相关。
  • 作者称,这种方差关系适用于多种趋势跟踪定义。
  • 恰当的测量显示,综合CTA表现的正凸性强于预期。
  • 文章指出趋势策略与风险平价投资组合之间存在联系。
  • 文中提出的宽跨式期权组合旨在提供长期方差敞口。

# Tail protection for long investors: Trend convexity at work









The performance of trend following strategies can be ascribed to the difference between long-term and short-term realized variance. We revisit this general result and show that it holds for various definitions of trend strategies. This explains the positive convexity of the aggregate performance of Commodity Trading Advisors (CTAs) which -- when adequately measured -- turns out to be much stronger than anticipated. We also highlight interesting connections with so-called Risk Parity portfolios. Finally, we propose a new portfolio of strangle options that provides a pure exposure to the long-term variance of the underlying, offering yet another viewpoint on the link between trend and volatility.
