BCH Heads Into Thursday Print With Borrow Tightening Fast

Banco de Chile reports Q3 results on October 29 with the lending market tightening sharply into the print, even as broader positioning remains relatively calm.

The most notable pre-earnings development is in the borrow market. Availability has dropped to 50%, roughly half the shares previously available are now out on loan, and down sharply from above 88% just a week ago, a 43% tightening in seven days. That move has come alongside a 38% rise in short interest over the past month, with shares short climbing to around 1.1 million. Cost to borrow remains modest at 1.31%, so the squeeze pressure is limited, but the directional shift in availability is worth watching. The stock itself has pulled back 9.4% over the past month to $38.33, with a further 1.5% slide on the week.

Options positioning points in the opposite direction. Call activity heavily dominates the open book, with the put/call ratio at just 0.0035, well below its 20-day average of 0.007, and 1.2 standard deviations below that mean. That is near the lowest defensive positioning of the past year, even as the stock has been falling. Bulls holding through the decline are not hedging aggressively, suggesting confidence rather than complacency, or simply a thinly traded options market given BCH's ADR structure.

The analyst picture is straightforward but worth framing carefully. The consensus is Neutral. JP Morgan trimmed its target from $45 to $44 on October 6, keeping the Neutral rating, after having raised the same target twice through 2025 and into mid-2026. UBS cut more aggressively in May, from $48 to $39. Both firms see fair value around or just above where the stock trades now, leaving little room for a re-rating on valuation alone. The price-to-earnings multiple has compressed nearly a full point over 30 days to 12.8x, and price-to-book has fallen to 2.73x, both moving toward more attractive territory. Against that, forward earnings estimates rank in the 96th percentile for year-on-year growth, a figure that reflects a high bar the company will need to clear.

Ownership is heavily anchored. Quiñenco SA holds 51.2% of shares and has not moved. BlackRock and Vanguard both added modestly in the most recent reporting period. The stable base limits float-driven volatility, but also means that price discovery rests almost entirely on the ADR market and a relatively small free float.

The October 29 print will test whether BCH's earnings growth trajectory justifies the stock's premium to book amid a tightening borrow market, falling availability and a stock that has lost nearly a tenth of its value in a month.
