- What is the current HYBL short interest?
- As of the May 15, 2026 settlement, State Street Blackstone High Income ETF (HYBL) short interest is 10.1K shares, a -82.93% change from the prior period. FINRA publishes short interest twice monthly on the 15th and last business day of each month under Rule 4560.

- How does HYBL short interest affect options pricing?
- High short interest changes options pricing through three mechanics: borrow-rebate effects (synthetic long stock trades below frictionless put-call parity by approximately the borrow rebate when shares are hard-to-borrow), gamma-squeeze setup risk (if dealers are short gamma against retail call buying, dealer hedge flow can amplify upward moves), and elevated event-vol pricing on names with squeeze potential.
