Three converging signals are drawing attention to SGOV, the iShares 0-3 Month Treasury Bond ETF. Short shares have climbed steadily for three weeks. The put-call ratio just broke above two standard deviations. Yet the borrow market tells a different story.
Short interest in SGOV hit 4.55M shares on May 1 — up 14.5% week-on-week. That's the third consecutive week of double-digit percentage gains. A month ago, the figure stood above 8M shares, so the current level remains well below its early-April peak. This looks less like a directional short and more like active repositioning around Treasury ETF flows.
The cost to borrow complicates the picture. CTB sits at just 0.46% — down sharply from 1.75% a week ago, even as short shares rose. Lending availability remains comfortable. This divergence is notable: more shares being shorted, yet lenders are not tightening supply. That suggests the additional short demand is being easily absorbed.
The put-call ratio moved to 0.2352 on May 1. That's 2.35 standard deviations above its 20-day mean of 0.166. For context, the 52-week low PCR is 0.07 and the high is 4.78 — so the current reading is still historically subdued. But the directional shift is meaningful. After weeks of steady, low PCR readings through mid-to-late April, options buyers are showing a modest but measurable increase in demand for downside protection.
The ORTEX short score stands at 37.4, up from 29.3 on April 17. That move — nearly eight points in two weeks — reflects the growing convergence of short and options pressure.
SGOV is a near-cash instrument. It holds Treasury bills maturing in under three months and trades close to par ($100.41 as of May 1). Short positions in this ETF typically reflect hedging or basis trades, not outright bearish bets on the underlying. The sharp halving of short interest between early April and mid-April — from ~8M shares to ~3.6M — and the subsequent rebuild to ~4.5M suggest institutional players are actively adjusting hedge ratios around rate positioning.
The falling CTB alongside rising shorts reinforces this. When borrowing becomes cheaper even as demand rises, supply is expanding in parallel. That's the signature of a liquid, well-functioning lending market — not a squeeze setup.
