BSAC Shorts Near One-Year High As Earnings Arrive

BSAC has seen its short position grow faster in the past week than almost any other stretch in the past year. Shares short rose 29% over the seven days to October 28, reaching roughly 1.04 million shares, the highest level in at least a year. That weekly move runs 1.6 standard deviations above the stock's typical weekly shift, a statistically unusual acceleration into the print.

The borrow market has not tightened to match. Availability remains very loose at 591% of short interest, meaning there are nearly six shares available to lend for every one already borrowed. Cost to borrow has actually eased, falling 5.6% on the week to 0.41%, and is down about a quarter from its level a month ago. New short positions are cheap and easy to establish, which partly explains why the short count has been able to climb without any friction in the lending market. The ORTEX short score edged down slightly to 35.4 on October 28 from a recent peak of 36.5, though the month-long trend remains upward.

The stock closed at $31.49 on October 29, down 7% over the past month. On options, the put/call ratio has held at zero for nine consecutive sessions. Against a 20-day average of 0.83, that reads more than one standard deviation below the mean, a sharp reversal from the 1.5 reading that persisted through much of September and early October. The absence of put activity in the final stretch before earnings contrasts with the build in short positions: one group is adding bearish exposure via the stock-loan market while another has stepped back from downside protection in the options market.

Analyst opinion sits on the positive side of neutral, though with meaningful dissent. JP Morgan holds an Overweight rating but trimmed its target to $39 from $43 on October 6. Goldman Sachs carries a Sell with a $33 target. UBS is Neutral. The mean price target across the consensus is roughly $35, a 11% premium to the current price. The stock's price-to-book multiple has compressed by about 6.5% over the past 30 days to 2.3x, and the P/E has drifted down to 10.8x over the same period, reflecting the share price weakness rather than any change in the earnings base.

The print will test whether the quarterly numbers can justify the gap between the current price and the analyst consensus, or whether the short interest build that has accelerated through October proves the better read on the bank's near-term trajectory.
