XLK shorts rebuild as the rally reverses

XLK has given back nearly all of October's gains, falling 7% over the past week to $176.51, and the short-interest trend that was unwinding a week ago has quietly turned the other way.

The reversal in positioning is the most notable development since the last note. Short interest had been trending lower through mid-October, reaching a trough near 20.4 million shares around October 14. It has since rebuilt steadily, climbing back to 22.6 million shares, or 6.9% of the free float, up roughly 1.6% on the week. That said, the absolute level remains well below the late-September peaks above 24 million shares, so this is a rebuild rather than a fresh assault. The borrow market tells a consistent story: cost to borrow has edged up to 0.53%, a 13% rise on the week, though at that level it remains firmly in the cheap-to-borrow category. Availability is loose at 353%, meaning the lending pool holds more than three shares for every one borrowed. There is no squeeze dynamic here.

Options positioning has remained persistently defensive and barely budged despite the selloff. The put/call ratio is 2.00, fractionally above its 20-day average of 1.98, a z-score of just 0.27. The structure of the options market has been elevated for weeks now, running well above the late-September readings of 1.80 to 1.84, and that defensiveness has not dissipated as the fund has fallen. The 52-week high on the PCR is 8.12, so the current reading is nowhere near a panic extreme, but the sustained level well above 1.9 suggests protective put demand has become a persistent feature of positioning rather than a short-term reaction to any single catalyst.

The ORTEX short score has been drifting higher. It reached 44.5 on November 3, up from lows around 40 in late October. That score is mid-range rather than extreme, but the direction of travel matches the short-interest rebuild and the broader price weakness, three signals pointing the same way.

The previous note flagged that short sellers were not rebuilding into the rally from the mid-October lows. That has now changed. Short interest bottomed and turned higher as the price failed to hold above $189. What to watch from here is whether the short rebuild continues through the next few sessions or stalls, and whether the options put/call ratio, which has been structurally elevated for a month, begins to ease as a sign that defensive demand is finally being reduced.
