COT Report Advanced Topics for Producers: Futures and Options

From the Ag Optimus desk. This is the opinion of Ag Optimus. 

Our guide to reading the COT report covers the version of the report a producer needs most: net positions, two key columns, weekly changes, and yearly extremes. This is chapter two. It covers what that quick guide deliberately left out, including the gross long and short columns for every net number, the spreading column, the difference between the futures-only and futures-and-options combined versions of the COT report, the short and long report formats, and the role of open interest. None of this changes the core routine; it deepens it.

Key Takeaways

• • Net numbers hide structure. Every category reports gross longs and gross shorts — the net is just the difference, and two identical nets can describe opposite markets.

• • Decompose every net change. A declining net long can mean longs exiting or fresh shorts entering — a risk-off move versus an active bearish stance. The gross columns tell you which.

• • You could consider the futures-and-options combined COT report for ag markets. Commercials hedge with options too; the combined version counts that exposure, and the two versions diverge most around major reports.

Long, Short, and Net: Reading the Gross Columns

Everything in chapter one used net positions, and the net is the right place to start — it measures directional conviction. But the report publishes more: a gross long column and a gross short column for every category. The net is simply longs minus shorts, and that subtraction loses information an advanced reader wants back.

Scenario A is a two-sided market: funds hold real positions in both directions, and the 60,000 shorts are fuel for a rally — if the market turns higher, their covering adds to the buying. Scenario B is one-sided: conviction is just as long, but there are almost no shorts left to squeeze, so a rally has to run on new money alone. Same net, different market behavior.

Did Longs Leave, or Did Shorts Arrive?

This is a useful advanced habit in our opinion: when a net position changes, ask which gross column moved. Say Managed Money’s net long falls by 20,000 contracts. If the long column dropped, that’s long liquidation — funds taking risk off, often driven by mechanical models and quickly spent. If the short column expanded instead, that’s fresh speculative selling — an active bearish view on future prices. The net change is the same; the implication is not.

The same decomposition sharpens the commercial read. If the net short shrinks because commercials covered shorts, hedges are being lifted — grain priced and delivered, or coverage pulled. If it shrinks because commercials added new longs, the physical trade is accumulating ownership. A producer weighing what a “supportive” commercial column really means will find those thirty extra seconds in the gross columns worthwhile.

The Spreading Column: Positioned Without a Direction

Next to Managed Money you’ll see a “Spreading” column. It counts offsetting positions — a fund long December corn and short March corn holds a spread, not a directional bet. Spread positions are offsetting by nature, which is why the net figures do not count them — and why the net stays a clean measure of directional conviction. A rising spread count indicates active funds hedged month against month, without a directional stance — common around report days and contract rolls. Note it, then return to the columns that matter.

COT Report Versions: Futures Only vs. Futures and Options Combined

Every COT report comes in two versions: futures only, and futures and options combined. The futures-only version counts futures positions. The futures-and-options combined report adds options exposure, converted into futures equivalents using each option’s delta — so a deep in-the-money put counts close to a full short futures contract, while a far out-of-the-money call counts as a small fraction of a long.

For agricultural markets, the combined report is our weekly tables’ default. The reason is practical: the physical trade hedges with options constantly — put floors under unpriced grain, fences around fed cattle — and the futures-only version simply can’t see that exposure. Most weeks the two versions may potentially tell the same story. They may diverge when clarity matters most: during WASDE reports, quarterly stock releases, and acreage announcements, when option positioning builds fast — and after large price moves, when deltas on existing options may shift even if nobody trades. If the two versions disagree noticeably, that gap itself is information — a market carrying meaningful option-based positioning that a futures-only reader never sees.

Short Format vs. Long Format: The Other “Long and Short”

Besides long and short positions, the CFTC publishes each report in two display formats, short and long — and that applies to disaggregated futures only and futures and options combined alike. The short format carries what this guide has used throughout: positions and week-to-week changes by category, percent of open interest, trader counts, and the concentration of positions held by the largest four and eight traders.

The long format includes everything in the short format and adds one thing worth knowing: for applicable agricultural markets, it groups positions by crop year, old crop shown separately from other crop years. That split can be worth a look at the turn of the marketing year, because it distinguishes hedging against grain in the bin from hedging against grain still in the field. A commercial short concentrated in old-crop months is priced inventory moving to market; the same short building in new-crop months is next harvest being forward-priced. The combined-year view in the short format blends those stories; the long format lets you read them separately.

On the CFTC’s download page, this all lands as a practical choice: the Agriculture row offers four links — two versions, two formats each. Here is which one to click, and when.

Open Interest: The Participation Check

Open interest — the total number of contracts outstanding is the context behind every positioning move. The useful pairing is simple. Positioning changes with open interest expanding may mean new money is entering: fresh longs are meeting fresh shorts, and the trend is gaining participants. Positioning changes with open interest shrinking mean existing positions are closing: liquidation, covering, a trade winding down. A fund long that grows while open interest shrinks is a very different animal from one growing while participation broadens — the first is concentration, the second is conviction spreading. Chapter one told you to treat open interest as a context check; here’s the check.

The Advanced Routine, in One Paragraph

Maintain the chapter-one routine — commercials first, funds second, weekly change, yearly extremes — and add three questions when something looks stretched: which gross column drove the change; whether the two COT report versions — futures only and futures and options combined — agree; and whether open interest is expanding or contracting underneath the move. Thirty extra seconds of analysis could point to the difference between a market that is crowded and one that just looks crowded. Our desk completes that read before each weekly Grain & Livestock COT Report is written.

Frequently Asked Questions

Should I use the futures-only or futures-and-options combined COT report?

Use the combined report for agricultural markets. Commercial hedgers rely heavily on options, so the combined version converts that exposure into futures equivalents and shows real hedging activity. Compare the futures-only version alongside it to see how much of the positioning comes from options.

What does delta-adjusted mean in the combined report?

Each option position is converted to a futures equivalent using its delta — the option’s price sensitivity to futures. Options that behave like futures count almost fully; far-out-of-the-money options count only partly. Because delta changes with price, combined-report positions can move even in weeks with little trading.

How can I tell whether a net change came from longs or shorts?

Check the gross columns in the full report. If the long column moved, longs were added or liquidated; if the short column moved, shorts were added or covered. The distinction matters: long liquidation is risk-off, while new shorts are an active bearish bet — and the same logic applies in reverse on rallies.

What is the difference between the short format and long format COT report?

They’re layouts, not positions. The short format shows positions, weekly changes, percent of open interest, trader counts, and largest-trader concentration for each category. The long format contains all of that and, for applicable agricultural markets, groups positions by crop year — old crop separate from other crop years — which lets you tell hedging against inventory apart from forward-pricing of the next harvest.

Does the spreading column affect the net numbers?

No — that’s the point of reporting it separately. Spread positions are offsetting by definition, so they are excluded from net long and net short figures. A large or rising spreading number indicates active funds in the market without a directional stance either way.
