CHPY Shorts Ease but Stay Extreme as ETF Falls 12% on the Week

CHPY, the YieldMax Semiconductor Portfolio Option Income ETF, has seen a week of partial short-seller retreat, but the broader picture remains one of unusually heavy bearish positioning for an income-focused ETF.

The short interest story has shifted materially since last week's note. Shares short fell roughly 3% over the week to 1.99 million, bringing short interest as a percentage of the free float down to 89.4% from the 92.4% peak reported on October 8. That is still an extraordinary level for any ETF, let alone one designed to generate income through a covered-call overlay. The one-month change, however, remains stark: short interest is up 34% over 30 days, confirming that last week's surge was a genuine structural shift in positioning, not a temporary spike that has since unwound.

The lending market has moved in the opposite direction to short interest this week, with availability loosening notably. Availability has recovered to 64.4% from a pinch-point of just 2.6% on October 13, when the lending pool came close to fully depleted. That mid-week tightening was severe: with the 52-week low for availability at 0.87%, traders who needed borrows on October 13 were competing for scraps. The release since then is real, though availability remains well below the 200%-plus levels seen in mid-September, when the short build was just beginning. Cost to borrow has also eased, dropping 25% over the week to 4.5%, after touching 6.5% as recently as October 7. The direction of both metrics points to some covering or net new share creation loosening the pool, rather than any fundamental shift in borrow demand.

Options positioning has edged more cautious alongside the price decline. The put/call ratio is running at 0.70, above its 20-day average of 0.62 by roughly 1.7 standard deviations, the most defensive reading in several weeks. That is still well below the 52-week high of 0.94, so options traders are not in full-protection mode, but the trend in the PCR over the past fortnight has been consistently upward, moving from 0.56 in late September to its current level as the fund has lost 12% over the week and 5.7% over the past month. The ORTEX short score, which aggregates the lending and positioning signals, came in at 67.7 on October 15, down slightly from the 69.9 reading on October 7 but still well above neutral, consistent with a fund under sustained bearish pressure.

What to watch next is whether the mid-week availability squeeze on October 13 was an isolated clearing event or a sign that the lending pool remains structurally thin: a repeat episode where availability drops back toward single digits would be the clearest signal that the short position has not meaningfully covered despite this week's modest pullback.
