XLK has bounced 3.1% on the week to $186.44, yet short sellers are responding to the rally not by retreating, but by pressing harder — a posture that is becoming a recurring theme for this ETF.
Short interest has climbed another 14% over the past week, reaching 5.4% of free float — roughly 17.6 million shares. That extends a build that has now run for nearly two months, with the month-on-month increase approaching 23%. The last note observed bears adding into a sharp 9% drawdown; they are now adding into a 3% recovery, which makes the conviction here harder to dismiss as simple momentum-chasing. The ORTEX short score has ticked up to 41.0 from 34.7 a week ago, reversing most of the easing that followed the early-June sell-off. The pattern is consistent: each recovery attempt draws fresh short supply, not profit-taking.
The borrow market has tightened notably alongside the fresh short building. Availability has dropped from 548% last Monday to 326% by Tuesday's close — a 32% tightening in a single week. That is still comfortably within the normal range and far from the 41% floor seen at the 52-week worst, so there is no squeeze pressure yet. Borrowing costs have risen 24% on the week to 0.71%, their highest reading in at least six weeks, though in absolute terms that level remains very low. What is worth noting is the direction: tighter availability and rising cost-to-borrow running in parallel with a rising short share count suggests the demand for borrows is genuine and growing, not just measurement noise.
Options positioning has turned less defensive than it was a month ago. The put/call ratio has eased to 1.78, meaningfully below its 20-day average of 1.99 and running about 1.2 standard deviations under that mean. As recently as early June, the PCR was printing above 2.2. That shift suggests options traders are unwinding some of the downside hedges placed during the sell-off — a contrast with the short sellers, who are doing the opposite. The two camps are pulling in different directions this week: options flow is reflecting the price recovery, while short interest is treating it as an opportunity.
Institutional ownership is broad and stable. Wells Fargo held the largest disclosed position at 3.6% of shares as of March 31, with UBS adding nearly 3.5 million shares in that quarter — the largest single addition among the top holders. That kind of steady institutional accumulation sits in stark contrast to the rising short interest, reinforcing the picture of a market genuinely divided on near-term direction. The prior note framed this as a conviction short being pressed on momentum; the data this week — shorts adding into a bounce, options traders fading their hedges, institutions holding firm — deepens that tension rather than resolving it.
The question that frames everything heading into next week is whether the short sellers are right that the recovery is a fade, or whether the options unwind reflects something more durable about sentiment in mega-cap tech.
