SMH is trading at $600.31 — up 3.2% on the week — yet the borrow market is now at its most constrained point of the past year, with shorts refusing to cover into the rally.
The lending picture has deteriorated dramatically since the July 9 note flagged availability at 39%. It has since collapsed to just 21% — meaning only one share remains available to borrow for every four already lent out. That is the tightest the market has been since the 52-week minimum of 5.7%, which was hit earlier this year. The move is abrupt: availability was running above 90% as recently as July 7. Short interest reinforces the pressure. SI climbed 28% over the past week to 16.9 million shares, now at 16.5% of free float — the highest level in the 30-day window. That is a material escalation from the 13% range where it spent most of June. Bears added aggressively into the rally rather than retreating from it. Cost to borrow has risen 40% on the week to 1.21%, though it remains well below the June 24 peak of 1.83%. The ORTEX short score sits at 66.9 — a two-week high — reflecting the combined weight of elevated SI, tight availability, and rising borrow cost.
Options positioning has shifted meaningfully less defensive than it was just two weeks ago. The put/call ratio has dropped to 2.58, roughly 1.6 standard deviations below its 20-day average of 3.09. As recently as June 29 the PCR printed at 3.61 — the 52-week high. The retreat toward the lower end of the past year's range at 0.54 tells a different story from the lending market: options traders are reducing their hedges even as short sellers build. That divergence is the week's central tension. The borrow market screams caution; the options market is quietly turning constructive.
Institutional data — last reported as of March 31 — shows Managed Account Advisors as the largest holder at 28.8% of shares, though they trimmed by 2.25 million shares in Q1. Morgan Stanley moved the other way, adding 2.8 million shares to bring its stake to 19.3%. JPMorgan and Bank of America also added meaningfully. That Q1 rotation toward the major bank-affiliated holders is consistent with broader risk-on positioning ahead of the AI infrastructure spending wave, though the data is now 3.5 months old.
The three-week arc here is worth tracking closely. The July 8 note described shorts covering into a sell-off with availability loose and borrow cheap. The July 9 note caught the pivot — availability snapping from 93% to 39% in three sessions. Now availability has halved again to 21% in five more sessions, and short interest is back at a monthly high. The ETF has recovered $19 from the $581 trough. What to watch is whether availability continues toward the 5.7% floor seen earlier this year — and whether the options market, which is now relatively less hedged than at any point in the past month, starts to reassert its defensive posture as the borrow squeeze deepens.
