Speculative sentiment in the U.S. aluminium market turned slightly more negative in the latest reporting period, according to updated data on CFTC Aluminium speculative net positions released on 18 September 2026.
The net position slipped from -0.3K to -0.4K, indicating a modest increase in bearish bets by speculators. While the move is incremental, it underscores a cautious stance among market participants toward aluminium, with net shorts expanding rather than contracting.
The change suggests that traders remain wary of the near-term outlook for the metal, as positioning continues to lean on the short side rather than signaling a shift back toward net long exposure.
