USD, the ProShares Ultra Semiconductors ETF, enters the week with its lending market still extremely tight — and options traders sending the opposite message.
The borrow story remains the dominant signal. Availability has eased marginally from the 9.2% reading on June 23 but stays deeply compressed, down from above 1,000% just three weeks ago. To put that in plain terms: a month ago there were more than ten shares available to borrow for every one already lent out. Now there is roughly one available for every ten on loan. Cost to borrow has nearly doubled since June 11, climbing from 0.69% to 1.38% — a 43.7% rise over the month. Short interest itself remains technically modest at 1.57% of free float, but the velocity of the build is notable. Shares short jumped 24.7% in a single session on June 23, and the one-week rise is 22.6%. The lending pool is being absorbed quickly.
Options traders are reading the situation very differently. The put/call ratio has dropped to 0.48 — nearly 2.4 standard deviations below its 20-day average of 0.59. That is call-heavy positioning, closer to the 52-week low of 0.23 than to the high of 1.02. Traders buying calls are effectively betting on a recovery in leveraged semiconductor exposure, even as the borrow market signals mounting short demand. The divergence is the central tension in this name right now.
The ORTEX short score has drifted modestly higher over the past two weeks, reaching 47.9 from 43.7 on June 11. That move is consistent with the borrow tightening and short interest build, though the score remains mid-range rather than at extremes. The fund fell 12.3% on June 23 — a sharp single-session move for a 2x leveraged product tracking semiconductor names — and has given back just over 1% on the week despite a partial stabilisation. The one-month return is still positive at 1.7%, reflecting the broader semiconductor tailwind that had been supporting the fund into mid-June.
Overall, the setup is genuinely split: the lending market is behaving as if short sellers are building a position into weakness, while the options market is pricing in a rebound. What to watch is whether availability continues to compress toward the 52-week floor of 2.4% — and whether call-side options positioning holds or rotates as the semiconductor sector digests its recent volatility.
