Options traders are the most bullish they've been all year on CIBR. The put/call ratio hit 0.22 on June 23 — the lowest in 52 weeks. The 20-day average sits at 0.31. That's a z-score of -2.76, a statistically extreme skew toward calls.
The timing is notable. It coincides with a sharp tightening in the lending market.
Availability on CIBR has collapsed. One week ago, roughly 129% of shares short were still available to borrow — a comfortable, loose market. That figure has since fallen to 24%. Just one share is available for every four already borrowed.
The compression happened fast. Availability was above 120% as recently as June 10. It has dropped more than 80% in a single week.
Cost to borrow is up 28% over the past month, reaching 2.20%. That remains modest in absolute terms. But the direction — and the pace — tells a clear story. The borrow market for CIBR has flipped from easy to tight in under two weeks.
This data needs context. Short interest is only 0.24% of the float. That is an extremely low absolute level. The week-on-week increase of 20% sounds dramatic. In share terms, it is not — positions moved from roughly 299,000 to 360,000 shares.
The previous note from June 17 flagged a dramatic unwind of a large short position built in late May. That unwind is confirmed. What's happening now is a modest rebuilding at a far lower base. The availability tightening reflects that incremental demand, not a structural short squeeze.
Two signals are now pointing in opposite directions.
Options traders are aggressively positioned for upside. The put/call ratio has never been lower this year. The 52-week low was 0.10 — so there is still room to run, but the current reading already sits well below the historical norm.
Meanwhile, borrow demand is quietly building. Availability at 24% is tight. The 52-week minimum was 9.9% — so the floor is lower. But the speed of the move from 129% to 24% in one week warrants attention.
CIBR trades at $84.21, down about 1% over the past week. The ETF has largely gone sideways over the past month.
