SOXX has just delivered its strongest week in months, gaining 6.2% to close at $640.76 — a direct contradiction of the heavy short positioning that had been building throughout June.
The short-side story here is the central tension. Bears had been adding aggressively: short interest climbed 25% in a single week and is now up 64% versus a month ago, with 22.5% of free float held short. That is a substantial build. The previous note flagged bears reloading at $603 last Tuesday; the ETF has since rallied another 6% and the squeeze pressure embedded in that positioning is now visible in the price. Availability has actually loosened relative to last week — moving from 33% to 42% — suggesting some short covering occurred mid-week even as overall short interest remains elevated. Cost to borrow has eased slightly to 1.93%, down from highs above 3% seen earlier in June, though it remains roughly 18% higher than a month ago.
Options positioning has shifted meaningfully in favour of the bulls. The put/call ratio dropped to 2.33, now running more than 1.3 standard deviations below its 20-day average of 2.84. For context, the PCR was above 3.5 as recently as early June. That is a significant rotation — traders who spent May and early June stacking downside protection have been unwinding hedges into the rally. The 52-week low on the PCR is 1.28, so there is further room to unwind if the move continues.
The ORTEX short score holds at 67.5, broadly unchanged across the past two weeks despite the price move. That stability in the score alongside a 6% weekly gain is notable: it suggests the short-side thesis has not been abandoned — bears are bruised but have not capitulated. The lending market corroborates this. Availability has rebounded from the extreme tightness seen in early June (the 52-week low hit 0.43% on June 11-12, when the borrow pool was essentially exhausted), but at 42% it remains firmly in tight territory. There is still roughly one share available for every two already borrowed.
One data point worth watching is the June 4 event in the earnings history, which logged a 12.3% single-day decline followed by a partial five-day recovery. That was the sharpest reaction in the dataset. The ETF closed that week roughly 4.7% below where it started, meaning the bounce did not fully repair the damage. The current rally is happening against that recent backdrop — and with short interest 64% higher than a month ago, the borrow dynamics heading into any new macro catalyst will be worth tracking closely.
The week ends with bulls firmly in control of the tape, but with a short base that remains historically large and a borrow market that loosened only modestly on the week's move — the next catalyst, in either direction, lands into a still-charged setup.
