GABF, the Gabelli Financial Services Opportunities ETF, enters mid-May with short sellers unwinding positions at a striking pace — while borrowing costs quietly tick upward against the grain.
The defining feature this week is the collapse in short interest. Estimated short positions have fallen roughly 90% over the past month, dropping to just 609 shares as of May 12. That is a tiny fraction of this ETF's float, representing under 0.1% of the free float. The ORTEX short score has followed suit, retreating from a local peak of 46 on May 5 down to 28.6 by May 12. The direction is clear: whatever pressure had built up in late April and early May has largely dissipated.
The lending market tells a slightly different story. Cost to borrow has edged up roughly 17% over the past week to 6.2%, reaching its highest level since early March. That move is modest in absolute terms — the rate spent much of February above 7% — but it runs counter to the sharp drop in short interest. Availability, meanwhile, has completely opened up: with utilisation effectively at zero as of May 12, the lending pool is fully available. The 52-week peak on utilisation was 100%, so the contrast with today's idle market is notable. The combination of rising borrow cost and near-zero positioning suggests the marginal cost of shorting this ETF is creeping higher even as demand for the trade has all but evaporated.
GABF is a small, specialist vehicle — market cap around $54.8 million — focused on financial services names. With no upcoming earnings event, no analyst coverage, and no meaningful institutional flow data available, the story here is almost entirely one of positioning mechanics rather than fundamental catalysts. The price has slipped about 1% on the week to $43.86, modest against a 2.6% gain over the past month. The combined ORTEX score of 28.1 places it in the lower tier of short-selling interest, reinforcing the picture of a low-conviction, low-activity name.
The one thread worth watching is the divergence between rising borrow costs and a near-empty short book. If financial sector sentiment sours and traders look for targeted exposure to fade the theme, GABF's borrow rate — already elevated relative to a near-zero position — could move quickly. For now, positioning looks dormant rather than directional.
