SKYY Options Demand Spikes as Borrow Market Tightens

Options traders are buying downside protection on SKYY at an unusual rate. The put/call ratio hit 0.64 on July 21. That is 2.85 standard deviations above the 20-day mean of 0.49.

The ETF tracks cloud computing stocks. It closed at $136.02 on July 21, down 2.4% on the week.

Puts Dominate the Options Tape

The PCR has been remarkably stable for weeks. From June 8 through July 17, it barely strayed from a tight 0.44–0.49 band. Then it jumped sharply on July 20 and held above 0.63 the following day. That is a near-30% spike in put demand relative to calls, compressed into two sessions.

The 52-week PCR range runs from 0.25 to 4.63. The current reading is elevated but not extreme in absolute terms. What stands out is the speed of the move from a historically calm baseline.

Borrow Market Has Tightened Sharply

Availability in the lending market sits at 32.1% — meaning roughly one share is available to borrow for every three already lent out. That is a tight reading. It has deteriorated fast. As recently as July 10, availability was above 146%. It compressed to 32–36% over the following week and has stayed there.

The 52-week minimum availability was 1.5%. The current level is well off that extreme. But the direction matters. Availability has dropped more than 9% in the past week alone.

Cost to borrow tells a different story. It fell sharply to 0.56% on July 20, down from a recent peak near 1.57% on July 14. At current levels it remains low. That limits the signal from CTB alone.

Short Interest: Small but Moving

Short interest itself is low. At 0.85% of free float, it barely registers as a structural short position. But it rose 34% in the past week — from roughly 149,500 shares on July 10 to 200,000 shares on July 20. That is a meaningful increase in rate, even if the absolute level is modest for an ETF of this size.

The ORTEX short score sits at 46.3. It is broadly stable and does not flash an extreme reading in either direction.

What the Signals Are Saying Together

The convergence here is noteworthy. Options traders moved quickly from a long-call-biased stance toward hedging. Simultaneously, the borrow market tightened significantly — fewer shares available relative to those already borrowed. Short interest ticked up.

None of these signals is alarming in isolation. SKYY remains a broadly-held, diversified cloud ETF with 150 institutional holders on record. Two Sigma added nearly 179,000 shares as of March 31. Several large holders, including Morgan Stanley and UBS, trimmed.

What to watch: whether the PCR normalises back toward 0.49 in the coming sessions, or whether put buying continues to accelerate as cloud earnings results land.
