Abstract

In this article, the impact of investment horizon on asset co-skewness is examinedboth empirically and theoretically. We first detail a strong horizon-based estimationbias for co-skewness. An asset that has positive co-skewness at one horizon mayhave negative co-skewness for others. This phenomenon is particularly evident forsmall-capitalization stocks. We then propose a theoretical model to estimate long-horizonco-skewness using data observed at the shortest horizon, which emphasizesthe role of adjustment delays in the pricing of market-wide information amongsecurities. Co-skewness is only found to be priced in the cross-section of stockreturns for a small range of short horizons, calling into question the universal validityof the three-moment model.

摘要

本文从实证和理论上研究了投资期限对资产协偏度的影响。我们首先揭示了协偏度在不同投资期限间的估计偏误，即在一个期限下具有正协偏的资产可能在其他测度期限中具有负协偏，且这一现象对于小市值股尤为明显。然后，我们提出了一个理论模型，旨在基于单位期限内数据来估计更长期限的协偏度，该模型强调了定价迟滞在对股市资产定价的显著影响。协偏度被发现仅在较短的投资期限下的股票收益横截面中被定价，这使基于三阶矩的资本资产定价模型的普遍有效性受到质疑。(JEL G10, G12, G14)
