Options traders turned sharply defensive on Tuesday. SPY put-call ratio jumped to 1.99 — a z-score of 2.14, the highest in weeks. That's happening even as the short sellers who drove the prior cycle have nearly finished covering.
The divergence is the story. Shorts are out. Options hedgers are stepping back in.
The PCR move on July 28 stands out. At 1.99, it is well above the 20-day mean of 1.75 and sits at a z-score of 2.14. The 52-week high is 2.40, so this is elevated but not extreme. What makes it notable is the speed. Just last week, PCR was 1.67. It rose 19% in a single session.
That is the options market pricing in tail risk. Whether that risk is geopolitical, macro, or simply a hedge against the recent rally is unclear from the data alone. What is clear: put demand spiked sharply on Tuesday.
The short covering that dominated last week's report is now embedded in the data. SI sits at 9.4% of the free float as of July 27, down from the 10.5–10.6% plateau that held from July 13 to 22. The 11% weekly decline is the largest cover of the current cycle.
Shares short stand at 96.4 million — roughly where they were in early July before the Iran escalation rebuilt positions. The thesis that drove that rebuild has unwound. The data is consistent with the July 27 report: shorts abandoned Iran-driven positions following the ceasefire news.
Availability now reads 2,608% — more than 26 shares available for every one currently lent out. That is the loosest reading since before the Iran escalation began in mid-June. For context, availability hit as low as 194% on June 19 at the peak of geopolitical fear.
Cost to borrow has pulled back to 0.25%, down 44% over the past month. The borrow market is no longer pricing in stress.
The tension now is between positioning signals. Short sellers have covered. The borrow market is loose. Yet options traders bought puts aggressively on Tuesday.
The ORTEX short score sits at 44.2 and has been declining steadily from 48.1 on July 21. That directional fall reflects the short cover and easing borrow conditions.
The put-call ratio spike sits against that backdrop as a counter-signal. It does not reverse the short cover story. But it suggests at least one corner of the market is not fully convinced the risk has passed.
