GBCI Bears Build Into Earnings as Options Signal Unusual Optimism

Glacier Bancorp reports its third-quarter results today with a notable tension between rising short positions and unusually bullish options positioning.

Short sellers have been quietly pressing their case throughout October. Short interest has climbed 28% over the past month to reach 8.4% of the free float, roughly 10.9 million shares. That is a meaningful and sustained build, not a single-session swing. Days to cover stand at 9.4, which means unwinding the position at normal trading volumes would take the better part of two weeks. Despite that, the borrow market remains unthreatening: cost to borrow has actually fallen 22% over the past week to 0.44%, and availability at 691% is well off its tightest reading this year, leaving plenty of room for new shorts to enter without a squeeze.

Options tell a sharply contrasting story. The put/call ratio has collapsed to 0.25, nearly two standard deviations below its 20-day average of 0.57. That marks one of the most call-heavy postures of the past year, with the 52-week low at 0.32. The shift happened abruptly: through mid-October, the PCR held above 0.70, broadly consistent with the regional bank sector tone. Then in the last few sessions it dropped hard, reflecting a surge in call buying ahead of today's print. The stock has followed, rising 3% on Wednesday and 5% on the week to close at $45.99.

Covering analysts lean constructively into today. The consensus remains Buy or equivalent, with targets ranging from $54 at Stephens to $60 at Piper Sandler, representing meaningful upside from current levels. The bull case centres on a ninth consecutive quarter of net interest margin expansion, credit quality with non-performing assets at just 25 basis points of total assets, and loan growth running at low to mid-single digits with newer Arizona and Texas markets accelerating above 7%. Bears point to the familiar headwinds for Western US regional banks: real estate exposure, rate sensitivity, and an acquisition-heavy model that carries integration risk. Worth noting that the consensus snapshot is roughly two weeks old, so it may not fully reflect any immediate pre-earnings repositioning.

FDIC call report data via the Federal Deposit Insurance Corporation adds useful colour on the bank's own regulatory filings. Net income for the quarter ending June 2026 came in 76% above the same quarter a year earlier, and net loans and leases have now risen for five consecutive quarters to $21.1 billion. The FDIC dataset covering GBCI's insured bank charters has not yet been tested as a leading indicator against the company's reported figures, so these readings are backdrop context rather than a read on today's print.

Institutional ownership shows no alarm signals. BlackRock built its position by nearly 1.7 million shares in the most recent quarter to hold 13.6% of the company. Goldman Sachs Asset Management added over 700,000 shares. No activist 13D holder is on the register. The only notable 13G change is Capital Research Global Investors falling from 5.9% to 4.3%, a passive reduction that crossed back below the disclosure threshold.

Today's print will test whether the NIM expansion story has legs into a quarter when the rate environment became less supportive, and whether loan growth in core and newer markets is tracking management's full-year guidance.
