Why Short Interest Matters

Short interest is the number of shares that have been sold short but have not yet been covered or closed out. Short selling is when a trader sells shares of a company they do not own, with the hope that the price will fall. Traders make money from short selling if the price of the stock falls and they lose if it rises.

Short interest is important to track because it can act as an indicator of market sentiment towards a particular stock. An increase in short interest can signal that investors have become more bearish, while a decrease in short interest can signal they have become more bullish.
