A recent economic report from the Commodity Futures Trading Commission found continuing differences in the movements and returns of equities and commodity markets, contrary to reports of increasing convergence between these asset classes.

The report, which analyzed the main equities and commodity benchmarks from 1991 to the present, noted some instances between 1997 and 1999 when the markets moved together, but overall found “no statistical evidence of any long-run relationship” between the two markets.
