CATY Short Interest Climbs to Yearly High as Peers Pull Ahead

Among the regional banks most correlated with CATY, short positioning is thinner than it is here. UBSI, FNB, and CVBF all trade with correlation above 87% and each gained more than 3% on the week. Cathay General Bancorp added 2.2% to close at $60.67, a touch behind the peer median, while short interest climbed to 5.2% of the free float, the highest level recorded in at least a year.

The build in short interest is the standout development this week. From mid-September to now, reported short shares have risen by roughly a third, up 33% over the past month and 4.4% in the past week alone, reaching approximately 3.56 million shares. That pace of accumulation is notable relative to where CATY was trading just six weeks ago, when short interest was closer to 2.5 million shares. Despite that build, the borrow market shows no stress. Availability is running at 1,237%, meaning there are more than twelve times as many shares available to lend as there are currently borrowed. Cost to borrow is just 0.43%, among the lowest readings of recent months and down nearly 9% on the week. The lending pool is well-supplied, and new short positions can be established cheaply.

Options positioning has shifted in the same direction as short interest. The put/call ratio moved to 1.0 this week, up from 0.98 where it had been anchored for most of October, and now sits three standard deviations above its 20-day mean, the most defensively skewed reading in recent weeks. That combination, rising shorts and a defensive options tilt, points to a market leaning cautiously into the bank's quarterly earnings release due today.

The Street is cautiously neutral on the stock and has been for some time. After Cathay reported its prior quarter results in late July, several analysts lifted price targets: Keefe Bruyette moved to $67, DA Davidson to $66, and Stephens to $63, all while maintaining hold-equivalent ratings. Piper Sandler, the most bearish voice in the group, raised its target to $53 from $49.50 but kept its Underweight. The mean consensus target is $65, about 7% above the current price. The bear case centres on a declining allowance for credit losses and rising non-performing loans, while the bull case leans on margin resilience and the bank's focus on small and medium businesses within its target communities. The most recent action was StoneX initiating coverage with a Hold in late September, adding another neutral voice without a published target. Valuation is undemanding: the stock trades at roughly 10.3 times trailing earnings and 1.19 times book, with both multiples slightly softer than a month ago.

Insider activity over the past 90 days tilts negative in aggregate. Director Richard Sun sold a total of 15,000 shares across four open-market transactions between late July and early September, at prices ranging from $62.08 to $63.31. Those sales were not made under a 10b5-1 plan, making them discretionary. The CFO's recent transactions were primarily option exercises and associated tax-withholding sales, compensation mechanics rather than conviction moves. Net insider activity over 90 days totals a disposal of around 36,600 shares worth roughly $2.3 million. Institutional positioning is stable: BlackRock remains the largest holder at 14.6% after adding modestly in the September quarter, and American Century added 383,000 shares to lift its stake to 3.0%. No 13D activist is on the register.

The FDIC call report data covering Cathay's insured bank charters shows net loans and leases have risen for five consecutive quarters, and total assets reached a record for a second quarter ($24.6 billion) in the period ending June. These are verified figures from ORTEX's alt data layer covering the bank's own regulatory filings, though the FDIC series has not yet accumulated enough history to be tested as a lead for the company's reported earnings. The next measure worth tracking is how the current earnings release, due today, squares with the short interest build of the past month and whether the peer group's slightly stronger weekly performance reflects a broader re-rating that CATY has yet to fully capture.
