CFTC Aluminum Speculative Net Positions
Published:
A weekly CFTC measure of speculative (non-commercial) net futures positioning in the COMEX Aluminum MWP (U.S. Midwest premium) contract, in thousands of contracts.
Full explanation
CFTC Aluminum Speculative Net Positions is the net position of non-commercial (speculative) traders in the COMEX Aluminum MWP futures contract ("ALUMINUM MWP - COMMODITY EXCHANGE INC.", CFTC contract market code 191693). MWP is the U.S. Midwest aluminium price-premium contract: it prices the regional delivery premium over the benchmark aluminium price, not the generic aluminium price itself. The figure is non-commercial long futures contracts minus non-commercial short futures contracts from the CFTC's Legacy Futures Only Commitments of Traders report (options are not included), shown in thousands of contracts. It is a positioning measure, not money and not a physical quantity of aluminium. Positions are measured as of Tuesday and normally published on Friday at 3:30 p.m. Eastern Time.
Why traders watch it
Traders use the data to assess how speculative positioning in aluminum has changed and whether positioning appears concentrated or one-sided. It can provide context for moves in industrial metals, commodity-linked currencies, and related equities.
Market interpretation
- Aluminum and industrial-metals futures
- May shape interpretation of price moves by showing whether speculative traders are becoming more net long or net short.
- Commodity-linked currencies and equities
- Can provide secondary context when aluminum is an important input to broader metals sentiment or company earnings expectations.
Stronger vs weaker outcomes
A larger net-long position may indicate that speculators have become more bullish on aluminum, while a larger net-short position may indicate more bearish positioning. Either outcome can also raise the possibility that price reactions become more sensitive if traders later reduce crowded positions.
A higher net-position reading may indicate relatively stronger speculative long exposure or weaker short exposure. It can suggest more positive positioning, but does not establish the reason for that positioning or guarantee a price outcome.
A lower net-position reading may indicate relatively stronger speculative short exposure or weaker long exposure. It can suggest more negative positioning, but does not establish the reason for that positioning or guarantee a price outcome.
Higher readings generally indicate more net-long speculative positioning; lower readings generally indicate more net-short positioning.
Release details
- Release frequency
- Weekly (Tuesday positions, published Friday 3:30 p.m. ET)
Typical volatility
Moderate. The report is backward-looking: positions are generally measured as of Tuesday and published later in the week. Classification categories, options treatment, open interest changes, and the distinction between COMEX aluminum products can affect comparisons over time.
Trading considerations
- Check the report's position date as well as its publication date, because the figures describe earlier-week positioning.
- Compare net positions with open interest and changes in long and short holdings rather than relying only on the headline net figure.
- Confirm which aluminum contract and trader classification the calendar provider uses before comparing historical readings.
- Consider the release alongside aluminum prices, inventories, supply news, and broader industrial-metals sentiment.
