The Changing Relationship Between Commodity Prices and Equity Prices in Commodity Exporting Countries

New paper by Rossi: We explore the linkage between equity and commodity markets, focusing in particular on its evolution over time. We document that a country’s equity market value has significant out-of-sample predictive ability for the future global commodity price index for several primary commodity-exporting countries. The out-of-sample predictive ability of the equity market appears around 2000s. The results are robust to using several control variables as well as firm-level equity data. Finally, our results indicate that exchange rates are a better predictor of commodity prices than equity markets, especially at very short horizons.
