IWM is in the second week of a sustained short-covering rally — short interest has now dropped to 27% of the free float, down from 30.8% just two weeks ago, yet the bearish read on small-caps remains far above anything that could be called neutral.
The unwinding has accelerated. Short interest fell another 10.4% on the week to roughly 78 million shares, or 26.97% of the free float — the lowest reading since early June and a meaningful step down from the 30.8% peak flagged in last week's note. That's a reduction of around 9 million shares in seven trading days. The previous note noted 86 million shares at 29.8% of float; the move since then is unambiguous. Bears have been covering, not adding. Cost to borrow has eased alongside the covering, dropping to under 1% after briefly spiking above 1.7% in mid-June — borrowing IWM has rarely been cheaper in the past six weeks. Availability has swung dramatically too: after touching a dangerously tight 40% level on July 6th, it has now loosened back to just over 100% — meaning the shares available to borrow now roughly match the total already lent out. The lending market is no longer signalling any kind of squeeze dynamic.
Options positioning, however, is running more defensive than short interest alone would suggest. The put/call ratio climbed to 2.87 on Monday — close to its 52-week high of 3.03 and about 1.2 standard deviations above the 20-day mean of 2.69. Put demand relative to calls is near its most elevated level of the past year, even as short sellers trim. That divergence is the most interesting tension in the current setup: the borrowing market is loosening, but options traders are still paying up for downside protection. The PCR spent the prior two weeks grinding lower from the June 18 peak of 3.03; Monday's jump back toward that level suggests put buyers aren't convinced the covering trend marks a genuine shift in sentiment.
The institutional ownership picture is dominated by broker-dealers rather than long-only managers, which for an ETF of this size is expected. Morgan Stanley added 13 million shares in Q1 (bringing its stake to 10.3% of shares), while Goldman Sachs added 4.5 million. Wells Fargo moved in the opposite direction, trimming 2.4 million shares in the same period. Merrill Lynch cut 3.9 million. These flows reflect hedging and market-making activity more than fundamental views on small-cap equities, but the scale of Morgan Stanley's build in Q1 is notable — it was the largest single-holder move in the filing period.
The ORTEX short score has edged down to 68.4 from 70.5 a week ago, consistent with the covering trend. A score in the high 60s still signals elevated bearish conviction — it hasn't dropped back to neutral territory. The score peaked at 70.5 on July 6th, the same session when availability hit its tightest point. Both metrics have since eased in tandem, which reinforces the read that the loosening is real and not a technical quirk.
What to watch: whether the put/call ratio fades back toward its 20-day average as the covering continues, or whether it holds near the top of its annual range — that gap between easing short interest and sticky options demand is the clearest tell on whether small-cap skepticism is genuinely receding or simply rotating from the borrow market into the options market.
