Frequently asked FMST short interest questions

What is the current FMST short interest?

Days-to-cover is 1.08, 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 FMST 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.
