HBM heads into its October 29 earnings release with the stock down nearly 5% on the week, trading at CAD 36.55, even as the borrow market remains extremely loose and short interest stays well below any level that would concern bulls.
The positioning picture is notable for what is absent rather than what is present. Short interest is a modest 1.94% of the free float, up around 3% on the week and 7% over the past month, but in absolute terms the build is small. There are roughly 199 million shares available to borrow against fewer than 8 million shorted, an availability ratio of over 4,100%, meaning the lending pool is nowhere near stressed. Cost to borrow has drifted up 16% on the week to 0.64%, but that remains firmly in the cheap-to-borrow range. The ORTEX short score stands at 29.6, placing HBM in the 70th percentile for short-side interest relative to peers, a rank that reflects modest rather than aggressive bearish conviction.
The broader sector is similarly soft this week, suggesting macro rather than stock-specific pressure. Close peer CS fell nearly 9% on the week, NGEX dropped 6.4%, and ERO slipped 5%. LUN and TECK.B held up better, each down around 1.3% to 1.4%. HBM's 4.8% decline sits in the middle of that range, not a standout loser but clearly caught in the same copper-sector downdraft. SCCO on the NYSE was the outlier, up just over 1% on the week.
The institutional register shows a picture of gradual repositioning among the larger holders. Fidelity (via FIL Limited) trimmed its stake from 8.4% to 6.3% as of August, and GMT Capital slipped from 5.51% to 4.6% as of mid-August. On the other side, Mirae Asset added 2.2 million shares as of September 30, Mackenzie Financial added 2.3 million, and BMO Asset Management added 1.3 million over a similar period. L1 Capital initiated a fresh position of nearly 10 million shares last reported at end of June. Dimensional Fund Advisors moved below the 5% disclosure threshold, now at 4.9%, down from 5.0% at year-end 2025. No 13D activist holder is on the register. All Schedule 13D/G positions are as last disclosed around the 5% threshold, and holders dropping below that level may not file again.
Analyst price target data is stale and has not been included here. Valuation multiples offer more current context. The stock trades at 13.4 times trailing earnings, a level that has compressed modestly over the past week. EV/EBITDA is at 6.3 times, also easing slightly. The price-to-book ratio is 1.78. Factor scores rank HBM at the 98th percentile for dividend scoring, the 62nd for EPS surprise, and the 67th for days-to-cover, a combination that flags solid fundamental delivery but a modest income yield from current dividends, with the most recent cash payments on record dating to early 2022. EPS surprise at the 62nd percentile suggests the company has beaten estimates more often than not but without the consistency of the top tier.
Earnings history reinforces that the print can move the stock. The last reported quarter in August produced only a fractional one-day move but gave back nearly 6% over the following week. The quarter before that, reported in late July, generated a 3.5% gain on the day and extended to nearly 18% over the five subsequent sessions. With the next release on October 29, the key variable is whether the copper price backdrop and operational delivery from Constancia and Copper World support the multiple the stock has been carrying through a strong year-to-date run, or whether the sector-wide softness of the past week reflects a more durable reassessment of near-term demand.
