Copper hits an all-time COT extreme as large speculators crowd the long side [Video]

Copper is the market I keep coming back to in this week’s Commitments of Traders report. Large speculators are now more net long than at any point in the available history of the data. This is not a five-year or ten-year reading. It is a true all-time extreme, and that degree of crowding deserves attention.

The signal does not tell me that copper has to reverse immediately. Large speculators tend to follow established trends, and an extreme can keep expanding while price continues higher. But if I were already long copper, this is the kind of reading that would make me review the size of that exposure and consider scaling some of it back.

Why copper’s all-time extreme matters

The closest recent comparison came in June 2024, when large-speculator positioning also became exceptionally stretched. Copper fell sharply shortly afterwards. I am not treating that episode as a forecast that the same sequence must repeat, but it shows why the present reading should not be dismissed as ordinary background noise.

An all-time extreme changes the balance of the question. The issue is no longer simply whether speculative positioning supports the existing trend. It is also how much additional buying may still be available, how crowded the long side has become and how vulnerable the market could be if sentiment begins to shift.

COT data is not a precise timing tool, so I would still look to price behaviour for confirmation. My conclusion is narrower: copper’s positioning has entered territory never recorded before, and the risk attached to an existing long position is now materially different from when participation was closer to its normal range.

Sugar repeats the structure seen around the March top

Sugar is producing a bearish COT change signal, with commercials recording a 43% change in their net positions. Small speculators remain highly optimistic at the same time. That combination is notable because the same positioning structure appeared around the March top.

I would not call another top solely from that comparison. The 43% move is a weekly change signal, not a historical positioning extreme, and the distinction matters. Even so, a sizeable bearish commercial adjustment alongside confident small-speculator positioning gives me a clear reason to watch whether price begins to validate the shift.

Lumber turns constructive after its pullback

Lumber points in the opposite direction. Commercial net positioning changed by 37%, generating a bullish COT change signal, while the iCOT Scores are also positive. The setup arrives after roughly three to four weeks of falling prices, so positioning is improving against a softer recent backdrop rather than after an extended rally.

What interests me is the alignment between the commercial change and the iCOT readings. I would still want price to stabilise before treating the move as confirmed, but lumber now offers a potential entry setup worth monitoring if the recent pullback begins to lose momentum.

Gold’s commercial shift points to short-term cooling

Gold recorded a 28% bearish change in commercial net positioning, a larger-than-average weekly adjustment after the market’s recent strength. Commercials are hedgers, so I do not read their positions as simple directional bets. The useful information is the scale and direction of the change relative to the recent structure.

For now, I see the reading as a warning that gold may be due for a short-term cooling phase rather than evidence of a major bearish reversal. Further positioning deterioration accompanied by weaker price action would make that case more convincing.

Cotton reaches a 245-report positioning extreme

Cotton adds another long-duration signal. Large-speculator positioning has reached a 245-report extreme, meaning the current reading is more stretched than anything seen across that substantial lookback window. Similar speculative extremes have historically preceded weakness.

As in copper, the extreme identifies an unusual condition rather than the exact point at which price must turn. I would watch whether the reading continues to expand with the trend or begins to unwind as price weakens. The second scenario would provide stronger evidence that the crowded positioning is becoming a constraint.

The main takeaway from this week’s report

Copper is the clearest story because its large-speculator position has moved beyond every previous reading in the available COT history. The June 2024 comparison adds useful context, but the present conclusion stands on the current data: long positioning is exceptionally crowded, and traders already exposed to copper have a strong reason to reassess risk.

The secondary markets reinforce the value of separating signal types. Sugar and gold show bearish weekly commercial changes, lumber has a constructive bullish change signal after a pullback, and cotton has reached a major large-speculator extreme. None of these readings should be treated as a standalone trading signal or as precise timing, but each shows where positioning is changing unusually quickly or has moved far outside its normal historical range.
