DEFINITION of 'Short Interest'

The quantity of stock shares that investors have sold short but not yet covered or closed out. Short interest is a market-sentiment indicator that tells whether investors think a stock's price is likely to fall. Short interest can also be compared over time to examine changes in investor sentiment. Investors use short interest to make predictions about the direction a particular stock is headed, and to measure the bullishness or bearishness of investors' sentiment towards the market as a whole.
