ARTY, the iShares Future AI & Tech ETF, enters July with short sellers unwinding positions at pace — and the borrow market telling a dramatically different story than it did six weeks ago.
The headline number is striking. Short interest has collapsed by more than three-quarters over the past month, falling from roughly 920,000 shares short in late May to just 177,000 by June 30. That puts short interest at only 0.43% of the float — a negligible level. Whatever concern drove that earlier short build has clearly dissipated, coinciding with ARTY gaining just over 2% in the past week to close at $76.16.
Availability tells that story most clearly. Back in early June, the borrow pool was effectively tapped out — availability dropped as low as 12.9% on June 10, meaning fewer than one share was available to borrow for every seven already lent out. That's the tightest level of the past year. Today the picture is reversed: availability has opened up to 325%, meaning borrowers face no material constraint. The transition happened fast. As recently as June 12, availability was still just 32%. The normalisation since then has been sharp.
Borrow cost, however, is moving in the opposite direction. Despite availability loosening dramatically, the cost to borrow has crept up — rising 19% over the week to 2.42% annualised, its highest reading in the 30-day window. That's a modest absolute level for an ETF, but the direction is worth noting given that short interest itself is near a floor. The most likely explanation is that residual short positions are more concentrated, with fewer willing lenders matching against fewer borrowers — a thinner market rather than a stressed one.
Options positioning has grown modestly more cautious over the past fortnight. The put/call ratio for ARTY has drifted up from the 0.25–0.27 range it held through late May to 0.43 now, sitting about 1.5 standard deviations above its 20-day average. That's not an extreme reading — the 52-week high is 0.76 — but the directional move is consistent with investors adding a modest hedge as the ETF approaches the highs. The ORTEX short score at 38.7 is subdued, reflecting the low and falling short interest rather than any elevated squeeze pressure.
As an ETF, ARTY carries no earnings catalyst, no insider activity, and no analyst price targets to monitor. What to watch next is whether that PCR drift continues — a further climb toward the 0.60–0.75 range would signal genuine nervousness — and whether the cost to borrow keeps rising even as short interest stays compressed.
