Frequently asked COF short interest questions
- What is the current COF short interest?
- As of the Apr 30, 2026 settlement, Capital One Financial Corporation (COF) short interest is 8.2M shares, a +11.53% 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 COF days-to-cover ratio?
- Days-to-cover is 1.92, 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 COF 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.
