Frequently asked BLCR short interest questions

What is the current BLCR short interest?
As of the May 15, 2026 settlement, iShares Large Cap Core Active ETF (BLCR) short interest is 124.9K shares, a -32.93% change from the prior period. FINRA publishes short interest twice monthly on the 15th and last business day of each month under Rule 4560.
What is the BLCR days-to-cover ratio?
Days-to-cover is 1.00, calculated as short interest divided by average daily volume. It estimates how many trading days closing all short positions would consume given typical liquidity. Values above 5 days are commonly cited as elevated; values above 10 days are squeeze-relevant.
How does BLCR 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. See the canonical short-interest documentation for the full mechanism.
