Monitor HBM's Q4 2026 13F filings to see if the selling continued or reversed. The cluster's bearish signal is tempered by the 45-day reporting lag — current institutional positioning may differ materially from these stale data.
Executive Summary
Three institutional asset managers trimmed their HBM positions in Q3 2026, with aggregate net selling of $29.4M. The largest reduction came from Artemis Investment Management, which cut 44.5% of its stake ($24.9M sold). This bearish cluster suggests a shared negative view on the copper/gold miner's near-term outlook, though the 45-day reporting lag means positions may have already been adjusted.
