Short Interest Ratio


BREAKING DOWN 'Short Interest Ratio'

This ratio provides a number that is used by investors to determine how long it will take short sellers, in days, to cover their entire positions if the price of a stock begins to rise. The short interest ratio can also be applied to entire exchanges to determine the sentiment of the market as a whole. If an exchange has a high short interest ratio of around five or greater, this can be taken as a bearish signal, and vice versa.
