AID - 10.3905/joi.2014.23.1.107 DP - 2014 Feb 28 TA - The Journal of Investing PG - 107--121 VI - 23 IP - 1 4099 - https://pm-research.com/content/23/1/107.short 4100 - https://pm-research.com/content/23/1/107.full AB - In this article, the authors find evidence for five commodity sectors that naturally conform to the standard functional categorizations typically used by the investment industry (industrial metals, energy, precious metals, grains & oilseeds, and livestock). Of the typical investment industry categorizations, only “softs” do not share a common factor. Using spot data to extend the history of commodity futures, the authors examine the performance of commodity sectors during periods of economic interest to investors and find the following: 1) The industrial metals sector is very sensitive to economic conditions, while the grains & oilseed sector is insensitive; 2) energy and precious metals are the sectors that earn the highest returns during periods of high and unexpectedly high inflation; 3) precious metals do not do well when economic conditions are poor and do not outperform the typical commodity during those periods; and 4) commodities in general, and all commodity sectors, earn positive returns during U.S. dollar crashes.TOPICS: Commodities, performance measurement
