Understanding
Reading E-MINI S&P 500 STOCK INDEX positioning
Every Friday the CFTC publishes how each trader class is positioned in E-MINI S&P 500 STOCK INDEX futures as of the preceding Tuesday. Leveraged funds are hedge funds and CTAs, the fast money; asset managers are pension funds and institutions, the slow money. Watching how each side moves week to week tells you who is driving price.
The COT Index above maps the current net position onto its one-year range: near 100% means the most stretched positioning in a year, near 0% the most washed out. Extremes are not timing signals on their own, but they tell you which side of the boat is crowded, and crowded trades unwind violently.
A useful habit: compare the two camps. When leveraged funds and asset managers agree, trends tend to persist. When they position against each other, volatility usually follows. The weekly table below the chart shows exactly that history.
