S&P 500 — Commitment of Traders

S&P 500 futures (E-mini) trade on the CME in contracts representing $50 times the index level. The COT report for S&P 500 futures is one of the most watched positioning reports in global finance because it reveals how leveraged money (hedge funds, CTAs) and commercial hedgers (pension funds, asset managers using futures as equity overlays) are positioned. Large net-short readings by speculators have historically coincided with market lows — excessive pessimism creates the conditions for a short-covering rally. Conversely, extreme spec longs suggest complacency and are a warning sign ahead of corrections. The COT Index for S&P 500 is used as a market-internal sentiment gauge alongside the VIX and put-call ratio. Commercial positioning is complex here: asset managers often appear on the long side using futures to equitise cash, which means their "commercial" classification doesn't carry the same contrarian signal as in commodity markets. Weekly changes in the non-commercial net position track institutional momentum and are an early read on whether fund flows support or resist the current trend.
