Hudbay heads into earnings with copper peers in retreat

HBM reports on October 29 having lost 21% in a month, with the stock now at CAD 30.76 and the copper sector under broad pressure heading into the print.

A note published earlier today covered the week's peer-group sell-off in detail. The picture has not changed materially since. ERO fell nearly 13% on the week, LUN dropped 11.5%, and CS lost 8.7%. HBM's own 8% weekly decline sits squarely in that range. NGEX was the relative standout, down less than 1%, pointing to some project-specific differentiation within the group rather than a blanket rerating. The macro rather than idiosyncratic read remains the more plausible explanation for HBM's move.

Short positioning does not add to the bearish case. SI holds at 1.88% of the free float, roughly 7.45 million shares, and edged down 3% on the week. Borrow conditions are equally relaxed: the cost to borrow is 0.70%, up about 19% week-on-week but still comfortably low in absolute terms. Availability is enormous at 3,332% of SI, meaning there are more than 191 million shares available to lend against a short position of 7.5 million. There is no meaningful squeeze dynamic here, and bears have not added conviction into the sell-off. The ORTEX short score of 29.7 is consistent with that: low and essentially flat across the past ten sessions.

Valuation multiples have compressed alongside the price. The P/E ratio has fallen roughly 3.5 points over 30 days to 11.3x, and EV/EBITDA has pulled back 0.7 points to 5.4x. The price-to-book now runs at 1.5x. These are not distressed levels, but they represent a meaningful de-rating from where the stock traded a month ago. The earnings yield factor ranks in the 66th percentile of the universe, suggesting the market is at least partially pricing in the weaker commodity backdrop rather than dismissing it.

Institutional flows tell a mixed story around the 5% threshold. FIL Limited, the parent of Fidelity International, disclosed a reduction from 8.4% to 6.3% of shares as of August, while GMT Capital trimmed below 5% to 4.6% as of the same month. Dimensional Fund Advisors also slipped just below the 5% mark to 4.9%. On the other side, Mirae Asset and Vanguard Capital Management both added in the September quarter, each adding over one million shares. The holders filing under Schedule 13G are all passive rather than activist. Positions are as last disclosed around the 5% threshold, and a holder dropping below that level may not file again. The net read is a modest thinning of the largest positions, offset by incremental buying from others.

Prior earnings reactions offer some context without implying a repeat. The August 2026 print produced a flat one-day move and a 5.7% decline over five days. The July 2026 print was the opposite: up 3.5% on the day and 17.9% over the following week. The most important variable at Wednesday's release is whether management addresses the copper price backdrop directly and whether Copper World and Constancia project updates provide incremental clarity, or whether the stock simply tracks the commodity.
