XLV, the Health Care Select Sector SPDR ETF, is caught in a sharper version of last week's tension: the fund keeps edging higher while short sellers and options traders pile on with fresh conviction.
The short-selling buildup has accelerated meaningfully since the September 16 note. Short interest has now climbed to 7.9% of free float — up from 7.1% a week ago and roughly 54% above where it was a month ago. In share terms, borrowed positions jumped from around 18.4 million on September 15 to over 20.6 million by September 22, a build of more than 2 million shares in a single week. That pace is no longer a curiosity — it is now one of the more aggressive short-building episodes this ETF has seen in the past six months. What makes the borrow picture notable is the tightening that has accompanied it: availability dropped from above 100% just one week ago to 35% now, meaning there are fewer than four shares left to borrow for every ten already out on loan. That compares with a 52-week low of 24%, so the lending pool is not yet fully used — but the direction of travel is unmistakable. Cost to borrow has nearly doubled from its August lows, running at 1.20% versus the sub-0.70% levels that prevailed for most of the summer. Borrow is tightening faster than the positions it supports are growing, which compresses the room available for further short expansion.
Options positioning reinforces the bearish lean, though the signal has shifted slightly from last week's near-extreme reading. The put/call ratio is now at 1.67, still well above its 20-day average of 1.50 and running more than 2.4 standard deviations above that mean. A week ago the z-score was close to 2.9; the ratio has climbed further in absolute terms but the mean has drifted up with it, reflecting how consistently elevated put demand has been throughout September. Traders are still paying to hedge healthcare exposure at a meaningfully higher rate than the recent norm — this is not a one-day spike but a sustained tilt. The 52-week high for the ratio is 2.67, so there is room for demand to intensify further.
The ORTEX short score has ticked up to 62.1 from 56.2 just ten days ago, reflecting the combination of rising short interest, tightening availability, and elevated put demand. That score compresses a set of signals that are all pointing the same way. Yet the price action continues to defy the bears: XLV closed at $169.89, up 1.3% on the week and down only 2.7% over the past month. Managed Account Advisors remains the largest holder at 9% of shares, with JPMorgan trimming its position by roughly 2.7 million shares as of the June quarter — a meaningful reduction that the current price recovery has not obviously reversed. Whether other institutional holders are quietly doing the same is not yet visible in the June-period data.
The setup heading into next week is a continuing tug-of-war between a price that refuses to break down and a positioning stack that grows more hostile by the day — with borrow availability now the metric most worth tracking for signs that the short trade faces a practical ceiling.
