What this data is

CFTC positioning (COT) for MICRO E-MINI S&P 500 INDEX

Every Friday at 3:30 pm Eastern the CFTC publishes who held what in US futures markets as of the previous Tuesday. Large traders are grouped by what they do, not who they are, and the report shows each group's long, short and spread positions. That's the Commitments of Traders report, and it's the only public window into institutional positioning across currencies, rates, equity indices, energy, metals and agriculture.

Financial futures use the Traders in Financial Futures format: dealers and intermediaries, asset managers and institutional investors, leveraged funds, and other reportables. Commodities use the disaggregated format: producers, merchants, processors and users; swap dealers; managed money; and other reportables. Positions too small to report are shown as nonreportable in both.

This page follows MICRO E-MINI S&P 500 INDEX only. The full list, the method notes and the cross-market view live on the CFTC positioning (COT) hub.

How to read it

  • Look at the net position of the speculative category (leveraged funds or managed money) relative to its own history, not its absolute size. Extremes are where reversals start.
  • When speculators and the structural side (asset managers or producers) sit at opposite extremes, the market is stretched. The structural side is usually right over months, the speculative side over days.
  • Open interest is the denominator. A net long that grew while open interest shrank is a crowd getting smaller, not more confident.
