XLP spent the week giving back last week's hedging unwind — short interest has climbed again and borrow costs have surged to a multi-month high, reversing the tentative calm that defined mid-September.
The most striking development this week is the cost to borrow. It has nearly doubled over the past seven days, rising from around 0.57% to 1.05% — an 84% increase that brings it to the highest level in the 30-day window. That move came alongside a week-on-week 6% rise in short interest, which now stands at 11.8% of the free float, up from 11.1% last week. The rebuild partially reverses the slight easing noted in the prior note, and taken together the two signals suggest fresh demand for short exposure rather than a mechanical roll. That said, availability remains comfortably normal at 158%, meaning roughly 1.6 shares sit available to borrow for every share already lent — so borrow pressure is real but not acute.
The options picture has shifted since last week's note, though not dramatically. The put/call ratio has edged back up to 3.41, roughly in line with its 20-day average of 3.34. The z-score of 0.24 is essentially neutral. Last week's article flagged a sharp drop in the PCR as a possible unwind of defensive hedging; that move has mostly reversed, with options traders returning to their baseline positioning rather than committing to a new direction. The 52-week PCR range remains wide — from 1.36 to 11.43 — so the current reading sits firmly in the middle, indicating neither panic nor complacency.
The ORTEX short score has ticked lower to 63.4 from a recent peak of 66.3 on Monday, an easing at the margin but still elevated relative to the 60–61 range that prevailed through mid-September. The score's slight retreat on the final day of the week, even as short interest remains elevated, may reflect the sharp single-session drop in short shares on September 22 — shares fell about 3.4% on the day after hitting a local high on September 21. The net weekly picture remains one of a fund under more pressure from bears than it was a month ago, despite Tuesday's partial cover.
Institutional flow data, reported through June 30, tells a somewhat conflicting story. Most of the large holders trimmed positions in Q2 — Morgan Stanley, Goldman Sachs, and Wells Fargo all reduced holdings meaningfully. Citigroup and Barclays moved the other way, each adding millions of shares. The bifurcation is consistent with XLP's role as a tactical allocation vehicle rather than a long-conviction hold: some desks rotating in for defensive exposure, others rotating out as risk appetite returned through the spring and summer. Raymond James and Menora Mivtachim both cut positions sharply, by more than three and two million shares respectively.
The ETF closed at $82.73 on Tuesday, up just under 1% on the day but down roughly 1.2% on the week and 3.8% over the past month. A quarterly dividend of $0.54 per share went ex-dividend this week, which typically generates mechanical short-covering and hedging activity around the payment date — the spike in borrow costs and the volatility in short shares over September 21–22 may partly reflect that dynamic rather than a pure directional trade. The next development to monitor is whether borrow costs retrace from their new weekly high or whether further short rebuilding keeps them elevated heading into October.
