SOXX closed the week down 0.9% at $567.44, but the more interesting story is what's happening beneath the surface: short sellers are quietly rebuilding positions even as the ETF trades 11.6% higher than a month ago.
Short interest has moved in the opposite direction to the recent note's narrative. The prior article, published September 23, described bears retreating into a chip rally. Since then, shorts have added back. Short interest climbed 8.9% over the past week to 24.3% of float, now running at 13.66 million shares. That reverses most of the cautious trimming noted last week and takes the position back toward its recent highs. What makes this notable is that the rebuild is happening into strength, not weakness. Borrowing costs remain low at 0.70%, down sharply from roughly 1.0% to 1.9% readings seen through mid-September. Availability has also loosened materially: after spending the bulk of September squeezed below 50%, the lending pool now has roughly 164% availability, meaning there are about 1.6 shares available for every one already borrowed. Bears are rebuilding at lower cost and with more room to work, a more comfortable setup for the short side than they had two weeks ago.
Options positioning reinforces the defensive tone. Put/call ratio has climbed to 1.65, almost two standard deviations above its 20-day average of 1.38. That's a clear shift from the 1.25 to 1.30 range that prevailed through most of August and early September. The week-long drift higher in the PCR, from 1.49 on September 21 to 1.65 by Tuesday's close, points to systematic hedging demand rather than a one-day spike. The 52-week low for the PCR is 1.18; the current reading is well above that, though still far below the 4.28 extreme hit on August 24 during the sharpest stress of the summer.
The ORTEX short score has ticked down modestly, from 67.2 on September 24 to 65.3 by September 29. That's a mild easing of the short-side signal, but the score remains elevated in absolute terms. Retail attention, as measured by Wikipedia page views against SOXX's own 90-day history, is running about 1.5 standard deviations below its recent average, suggesting the ETF is not drawing fresh retail interest at this price level.
The institutional picture from end-June filings shows a split: Goldman Sachs, the largest holder at 5.9% of shares, added 213,000 shares in the quarter. Susquehanna added heavily, growing its position by 877,000 shares to become the second largest holder. Holocene Advisors built a 760,000-share stake from scratch. Against that, Morgan Stanley trimmed 356,000 shares and BNP Paribas cut 143,000. The net picture is one where market makers and hedge funds were active on both sides through June, with the aggregate ownership spread across 350 holders offering no single dominant directional read.
What to watch next is whether the short rebuild continues into October or fades if the ETF holds above $560. The gap between a resurgent short position at 24% of float and a lending pool that is now relatively loose sets up an asymmetric dynamic: more shares available to borrow could encourage further short addition, but any sharp move higher would again compress that availability window quickly.
