XLI Bears Keep Retreating as Short Unwind Extends Into a Third Week

XLI bears are still heading for the exit, but options traders are growing more cautious as the industrial ETF slips quietly lower.

Short interest has continued its orderly retreat from September's peak. The previous note logged 15.6% of free float on October 12. It has since eased further to 15.5%, down roughly 2% on the week. From the September 25 high of 17.3%, the unwind now accounts for around 11% of that peak position. The ORTEX short score has drifted in a narrow range this week, holding near 68, well below the 70.4 reading from early October but still elevated in absolute terms. The month-on-month figure remains up around 7.7%, a reminder of how much was added during September's build even as the weekly trend continues to point the wrong way for bears.

The borrow market tells a less dramatic story than it did a month ago, though a subtle tightening is worth noting. Availability has dropped to 98%, down from 121% at the start of the week and well off the 136% reading seen on October 16. That is still a comfortable level, and the 52-week low of 1.3% (hit on September 21, when every share in the pool was effectively lent out) remains a long way off. Cost to borrow has fallen further, to 0.72%, down 15% on the week and nearly half what it was a month ago. Borrow conditions remain loose. The drop in availability is mechanical rather than alarming, but after three weeks of easing it merits a watch.

Options positioning tells a more cautious story than the retreating short interest might suggest. The put/call ratio is running at 1.82, modestly above its 20-day average of 1.66 and around one standard deviation above the mean. That is not an extreme reading by the standards of this ETF, which hit 5.54 at its 52-week high. But it does represent a firming from the relative calm seen on October 7 and 8, when the PCR touched its 52-week floor of 1.32. Options traders are adding downside protection, even as short sellers cover. The two signals are pulling in different directions.

The price action gives some context for the divergence. XLI closed at $166.80 on Tuesday, down 1.1% on the week and 1.7% over the past month. The move is not dramatic, but it is consistent. This is not a fund that has rebounded sharply as short interest has fallen. The unwind has not translated into a squeeze, which fits with the ample availability and low borrow cost throughout the period.

What to watch next is whether the short unwind continues at its current pace or stalls, and whether availability tightening accelerates toward the tighter levels seen in late September.
