XLB enters July with the story that defined mid-June returning in force: short interest has rebounded sharply after its brief retreat, and the options-driven bullish divergence flagged last week is fading.
The reversal in short positioning is the week's defining data point. Just one week ago, the note on this ETF described a "gradual retreat" in shorts from the June 9 peak. That retreat is over. Short interest has climbed 8.9% in a single week to 25.8% of free float — approximately 14.8 million shares — reversing almost all the ground given up since that early-June high. The monthly picture is starker still: shorts have grown 35.8% over the past 30 days. That is a material rebuild, not noise.
The lending market is loosening even as shorts rebuild, which is the counterintuitive wrinkle. Availability has risen to roughly 71.6% — up from as low as 12.7% on June 12, when the borrow market was extremely tight. The cost to borrow ticked up about 12% on the week to 0.59%, but remains firmly in the low range. What this combination says is that the fresh short supply is finding easier access to borrow than it did three weeks ago, when the squeeze pressure was more acute. The 52-week availability low was 3.9% — nothing close to that kind of stress is present right now.
Options are the story that has changed most visibly since last week's note. The put/call ratio was described then as 2.5 standard deviations below its 20-day average — a sharp bullish outlier. That signal has not held. The PCR now prints at 0.59, just 1.3 standard deviations below the 20-day mean of 0.66. The call-side enthusiasm has receded toward more neutral territory. The bullish divergence between options and short positioning that made last week's setup interesting has compressed: both markets are now pointing in a more aligned, cautious direction. The ORTEX short score of 61.5 is consistent with that — it has held in a narrow band between 59.6 and 62.4 all week, suggesting no dramatic shift in sentiment scoring.
The price action adds little clarity. XLB closed at $50.83, essentially flat on the week (down less than 0.1%) and off about 0.6% for the month. Given that short interest has surged 36% over 30 days while price is barely moved, the short thesis is not being rewarded — but it is also not being punished. The ETF is absorbing rising short pressure without breaking down, which keeps the tension between rebuilding bears and steady price alive heading into the second half of the year.
What to watch: whether the availability continues to loosen further as more borrow enters the pool, or tightens again toward the sub-20% readings that characterised early June — that shift in lending conditions, more than the short interest level itself, will signal whether the bear rebuild is approaching a squeeze inflection.
