Commitments of Traders (COT) Report: Reading Hedgers and Speculators

The Commitments of Traders (COT) report is a weekly release from the US Commodity Futures Trading Commission (CFTC) that shows how the big groups of traders are positioned in each futures market. It comes out on Friday afternoons at 3:30 p.m. New York time, with data as of the previous Tuesday. Traders use it to see whether speculators are crowded long or short and how hedgers are positioned, but it lags price and works best as background, not as an entry signal.

What the report contains

Futures brokers must report the positions of large traders above thresholds set by the CFTC. The CFTC groups these reportable positions into categories and publishes totals for each market. Positions too small to report are shown together as non-reportable.

There are several versions:

• Legacy report: the oldest format, splitting positions into commercial (hedgers), non-commercial (large speculators) and non-reportable (small traders).
• Disaggregated report: introduced in 2009 for physical commodities, with finer categories (below).
• Traders in Financial Futures: a similar breakdown for financial contracts such as currencies and interest rates.

Each comes in a futures-only version and a futures-and-options combined version.

The Disaggregated categories

Category	Who they are	Typical behaviour
Producer/merchant/processor/user	Miners, farmers, oil companies, refiners, food processors, merchants	Hedge physical business; producers usually net short
Swap dealers	Banks and dealers that sell hedges and index products, then hedge in futures	Positions reflect their clients' trades, including index investors
Managed money	Commodity trading advisers, commodity pool operators and similar funds	The main speculative group; many follow trends
Other reportables	Large traders that do not fit the categories above	Mixed
Non-reportable	Small traders	Mixed

Reading a COT line

For each category, the report shows long positions, short positions, spreading (positions held on both sides in different months) and changes since the previous week, plus total open interest.

Example (illustrative numbers): In gold futures, managed money holds 180,000 long and 40,000 short contracts, a net long of 140,000. Producers and merchants hold 20,000 long and 110,000 short, a net short of 90,000. Total open interest is 500,000 contracts. Managed money's net long equals 140,000 / 500,000 = 28% of open interest.

Why hedgers are often net short

A gold miner or a grain merchant holding inventory naturally sells futures to protect its business, as explained in lesson 2. So in many markets, the producer group is structurally net short. Their being net short is not a bearish signal; it is normal. What can carry information is how their position compares with its own history: unusually small hedging, or heavy commercial buying into a falling market, can suggest the physical industry sees value.

How traders use COT data

1. Spotting crowded positions

When managed money is net long at a multi-year extreme, many speculators are already in the trade. If the story changes, they may all try to sell at once, causing a sharp drop. The same applies in reverse for extreme net shorts, which can lead to short squeezes.

A simple way to measure "extreme" is a COT index:

COT index = (current net position - lowest net over the period) / (highest net - lowest net) x 100

2. Confirming a trend

A rising price with growing speculative net longs shows the trend is attracting money. A rising price while speculators are reducing longs may be driven by short covering or hedgers, which can be less durable. Neither is a reliable signal on its own.

3. Watching hedgers at turning points

Some traders look for commercial hedgers aggressively buying (reducing their shorts sharply) while prices are falling, as a sign that industry users see value. This is context to investigate, not a trade.

The limits of COT data

• It lags. Tuesday's positions are published on Friday, and prices can move a lot in three days.
• Crowded can stay crowded. In strong trends, managed money can stay heavily long or short for months. Many of these funds are trend followers themselves, so extreme positioning often goes hand in hand with a strong trend.
• Categories are imperfect. Swap dealers mix many types of client business, and one firm's trades may not fit neatly into a single category.
• Releases can be delayed. COT publication has been delayed during past US government shutdowns.
• Futures only. CFD and other over-the-counter positions are not included, although CFD prices follow the futures market.

A weekly COT routine

1. Download the latest report free from the CFTC website, or use a charting site that plots it.
2. For each market you trade, note managed money's net position, its change from last week and its COT index over three years.
3. Flag readings above about 90 or below about 10 as crowded.
4. For crowded markets in your direction, consider smaller new positions or tighter risk limits rather than reversing the trade.
5. Record the readings in your journal so you can check later whether they helped.
