Hudbay slides 8% in a week with earnings five days away

HBM enters its October 29 earnings release having shed another 8% this week to CAD 30.76, extending a bruising month that has now cost the stock 21%. The sell-off deepens a decline that was already visible in the previous note, and the question heading into Wednesday's print is whether the move reflects copper market anxiety shared across the peer group or something more specific to Hudbay's own story.

The sector angle is compelling. Broad-based weakness across TSX copper names this week suggests macro pressure rather than a stock-specific event. ERO fell nearly 13% on the week, LUN dropped 11.5%, and CS lost 8.7%. Against that backdrop, HBM's 8% decline looks broadly in line with the peer group rather than a signal of idiosyncratic trouble. NGEX was the outlier, down less than 1% on the week, suggesting some differentiation within the group around project-specific risk.

Short interest tells a story of genuine calm. At 1.88% of the free float, bears have not materially added conviction into the weakness. The short count actually edged down 3% on the week to roughly 7.45 million shares. Against 191 million shares available to borrow, availability runs above 3,300%, meaning the lending pool carries more than 33 times the shares currently borrowed. Cost to borrow has picked up 19% on the week to 0.70%, but that remains firmly in the low single digits and well within the cheap-to-borrow range. The ORTEX short score is 29.7, essentially flat over the past two weeks and placing HBM comfortably below levels that would suggest serious short-side pressure. Positioning here looks complacent rather than cautious.

The institutional register carries a few movements worth noting before the print. Mirae Asset added 2.2 million shares to reach 4.5% of the company in the quarter to September. Mackenzie Financial and Vanguard Capital both increased positions across the same period. Running the other way, Fidelity International cut its stake by 2.3 million shares and FIL Limited trimmed from 8.4% to 6.3% as of its August 13D/G filing, a meaningful reduction by the largest holder. GMT Capital also slipped below its prior 5.5% level to 4.6%, though as with all Schedule 13D/G disclosures, those stakes are as last disclosed around the 5% threshold and a holder can fall below 5% without filing again.

Hudbay's last earnings print, in August, produced a negligible next-day move of -0.2%, but the five-day reading was -5.7%. The print before that, in late July, produced a 3.5% one-day gain and a 17.9% five-day rally. That divergence in five-day outcomes reflects how much of the reaction in this name plays out over days rather than hours, a pattern worth carrying into next week's release. Analyst data in the snapshot is too stale to cite usefully. The valuation picture, however, has shifted notably: the P/E multiple has contracted by more than three points over the past month to 11.3x, and EV/EBITDA has compressed by 0.7 turns to 5.4x, almost entirely a function of the price decline rather than an earnings revision. At those levels, the stock is cheap relative to its own recent history.

The next five days reduce to a single question: whether Wednesday's numbers give long investors a reason to draw a line under the October slide, or whether a disappointing print confirms the sector-wide anxiety that has been pulling copper names lower all month.
