A short squeeze for Moderna occurs when it has a large amount of short interest and its stock increases in price. This forces short sellers to cover their short interest positions by buying actual shares of MRNA, which in turn drives the price of the stock up even further.

How often is Moderna's short interest reported?

Short interest is typically published by a stock exchange once per month. However, NASDAQ publishes a report for U.S. stocks, including MRNA, twice per month. The most recent reporting period available is March, 15 2025.
