Frequently asked MAC short interest questions
- What is the current MAC short interest?
- As of the Apr 30, 2026 settlement, The Macerich Company (MAC) short interest is 11.8M shares, a -1.30% change from the prior period. FINRA publishes short interest twice monthly on the 15th and last business day of each month under Rule 4560.

- Days-to-cover is 4.59, 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 MAC 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.
