The chart outlines the valuation of the GSCI relative to the S&P500. The GSCI comprises 24 commodities from all commodity sectors and serves as a benchmark for investment in the commodity markets and as a measure of commodity performance over time. If the ratio is low (green circles), it means that commodities are cheap relative to shares. If the ratio is at a high level (red circles), like during the Gulf Crisis in 1990, the prices of raw materials are relatively expensive.
The current ratio is 0.87 while the median is at 4.1. A return to the median gives 371% potential, but in most cases a rally doesn't stop at the median. In absolute terms, the scene seems set for a new bull market for commodities. According to Ned Davis Research, commodities gained 217% on average over the period of a bull market.
