Overview: Short interest is the total number of shares of a particular stock that have been sold short by investors, but have not yet been covered or closed out. It is used as a market sentiment indicator that tells whether investors think a stock's price is likely to fall. It can also be compared over time to examine changes in investor sentiment. Regulations and reporting requirements vary by country.
