Regulators, such as the U.S. Securities and Exchange Commission (SEC), and financial exchanges have taken multiple measures over the years to provide greater market transparency for investors. The U.S. futures industry’s primary regulator, the Commodity Futures Trading Commission (CFTC), has its own mechanism to provide a look behind the curtain, so to speak. It’s called the Commitments of Traders (COT) report, a weekly rundown of what the biggest players are doing in the markets for crude oil, grain, metals, and other commodities, as well as financial-based instruments such as Treasury futures.

For investors who are curious about the futures markets—or just interested in how commodities trading works—the COT report offers a snapshot of who’s buying and selling. Are speculators bullish on crude oil? Bearish on gold? The COT report can help answer such questions.

The COT report is a weekly summary enumerating the trading positions, known as “open interest,” of several categories of futures market participants—including big speculators—across an array of U.S.–based futures markets. The report, which is published most Friday afternoons and reflects positions as of the previous Tuesday, covers markets where 20 or more traders hold positions equal to or above reporting thresholds established by the CFTC.

The CFTC publishes COT reports “to help the public understand market dynamics,” according to the regulator. Reports are based on data supplied by brokers (or, in futures industry lingo, “futures commission merchants”), and by other parties, including futures exchanges. One of those exchanges, CME Group (CME), provides detailed graphs of COT data.

COT reports break down futures market participants into two broad “large-trader reporting” categories:

The CFTC further breaks down the noncommercial category into three subcategories:

The CFTC specifically states that its classifications don’t presume intent regarding traders’ positions and that the information “does not factor in determining trader classifications,” meaning that data for each commercial user includes all of its positions in a given commodity, regardless of whether the position is for hedging or speculation.

But while the CFTC claims to be agnostic, financial professionals who parse COT data can come to their own conclusions about what these traders—speculators, in particular—are up to and use that information to gauge market sentiment and strength or weakness in trends.

After a weekly COT report is released, many financial professionals go straight to the “managed money” category and check the net position, or the difference between long (bullish) and short (bearish) trades in different commodities.

For example, if managed money holds 200,000 long positions in crude oil futures and 75,000 short positions, those traders have a net long of 125,000 contracts. That likely means speculators are bullish on oil, expecting prices to rise.

In another example, if managed money holds 120,000 short positions in wheat futures and 80,000 long positions, that’s a net short of 40,000 contracts, indicating a bearish take that anticipates price declines. It’s also worth noting that COT reports include futures-only numbers, as well as versions that combine futures and options on futures.

COT reports could be likened to the SEC Schedule 13D forms, also known as the “beneficial ownership report.” These are required when an activist investor or a hedge fund acquires more than 5% of a company’s voting shares with the intent to influence or control its management or policies.

Unlike the Schedule 13D, however, the COT report doesn’t name names—just trader categories. But shifts in net long or short positions over time can reveal whether speculators or commercial firms are turning more bullish or bearish on a commodity.

COT data can be incorporated into trading strategies that help traders decide whether to take long or short positions in certain markets or industries. Some follow a contrarian approach to positions taken by smaller speculators based on the belief they are often wrong. Others follow commercial traders’ positions, assuming they understand their markets best.

The reports can also provide tools for analyzing market sentiment and forecasting potential price movements. By showing when different groups of traders have more bearish or bullish outlooks, COT numbers can provide valuable context for market analysis. There’s also the idea that COT data could offer an early warning of a major turn in a market, with extreme long or short positions possibly signaling the reversal of a trend. When commercial hedgers and large speculators strongly disagree on market direction, significant price movements often follow.

As an individual investor, you don’t necessarily need to trade futures to gain value from the CFTC’s weekly Commitments of Traders report. If your portfolio includes oil, mining, or other commodity-linked stocks, it’s worth watching the underlying markets. The COT report offers a clear read on what the big players are doing—and how and when sentiment may be shifting.
