DIA has undergone a swift reversal from the borrow stress documented just days ago — availability has snapped back and short interest has fallen, even as the ETF itself climbs to fresh highs.
The turnaround in the lending market is the week's defining data point. The previous note described availability collapsing to 23% — the tightest borrow conditions seen all year, with every share in the lending pool nearly fully committed. That episode has now unwound. Availability has rebounded to 130%, a 460% week-on-week improvement, meaning roughly one share is now available for every share already borrowed. Borrow costs have followed suit: cost to borrow has fallen 43% on the week to 0.44%, back toward the low end of the range seen across June and July. The 52-week low for availability remains 4.5%, a reminder of how extreme last week's episode was — but for now the pressure has materially eased.
Short interest tells a consistent story with the borrow data. The total short position has dropped 12% on the week to 4.87% of free float, with the daily reading ticking up modestly on July 28 from the prior session's low — likely routine noise rather than a fresh directional push. The one-month change is down 15%, confirming that the net trend over July has been shorts reducing exposure, not building. The ORTEX short score has drifted lower in parallel, edging from 55.8 a week ago to 53.3 today — still in the middle of the range, pointing to neither extreme pressure nor a clean short-covering narrative.
Options positioning has turned slightly more defensive over the week. The put/call ratio is running above its recent average at 1.51, roughly 1.2 standard deviations above the 20-day mean of 1.43. That is elevated relative to the range seen through most of July, though well below the June peaks above 1.8 when the broader macro backdrop was more uncertain. For a broad-market ETF like DIA, a PCR consistently above 1.4 reflects the structural tendency to use index puts for portfolio hedging rather than outright bearishness — but the recent tick higher is worth noting against a backdrop of the ETF closing at $526.89, up 1.1% on the week.
On the institutional side, Goldman Sachs and Wells Fargo remain the two largest reported holders at around 4.7% and 1.4% of shares respectively, with Goldman's position unchanged at the last 13F filing. Citadel trimmed its position by 1.4 million shares as of March, a notable reduction from what had been the third-largest holding. Dividend distributions have continued in small, irregular amounts through mid-July, consistent with the ETF's pass-through structure.
The next test for this data set is whether the availability easing holds or snaps back — the oscillation between tight and loose borrow conditions seen across the past three weeks has been unusually volatile for a fund of this liquidity, and that pattern alone is worth monitoring closely.
