英文摘要:
We decompose returns for portfolios of bottom-ranked, lower-priced assets relative to the market into rank crossovers and changes in the relative price of those bottom-ranked assets. This decomposition is general and consistent with virtually any asset pricing model. Crossovers measure changes in rank and are smoothly increasing over time, while return fluctuations are driven by volatile relative price changes. Our results imply that in a closed, dividend-free market in which the relative price of bottom-ranked assets is approximately constant, a portfolio of those bottom-ranked assets will outperform the market portfolio over time. We show that bottom-ranked relative commodity futures prices have increased only slightly, and confirm the existence of substantial excess returns predicted by our theory. If these excess returns did not exist, then top-ranked relative prices would have had to be much higher in 2018 than those actually observed -- this would imply a radically different commodity price distribution.

中文摘要:
我们将排名靠后的低价资产相对于市场的投资组合的回报分解为排名交叉和排名靠后资产相对价格的变化。这种分解是通用的,几乎与任何资产定价模型都是一致的。交叉衡量排名的变化,并随着时间的推移而平稳增长,而回报波动则由波动的相对价格变化驱动。我们的结果表明,在一个封闭的、无股息的市场中,排名靠后的资产的相对价格大致不变,随着时间的推移,这些排名靠后的资产的投资组合将跑赢市场投资组合。我们发现排名靠后的相对商品期货价格仅略有上涨,并证实了我们的理论预测的大量超额收益的存在。如果这些超额回报不存在,那么2018年排名靠前的相对价格将不得不远远高于实际观察到的价格——这将意味着商品价格分布的根本不同。
