What is the definition of Short ratio?



Short ratio is the number of shares sold short divided by the average daily volume.

= short interest / average daily volume

Short ratio is calculated by dividing the number of shares sold short by the average daily trading volume, generally over the last 30 trading days. The ratio represents the number of days it takes short sellers on average to repurchase all the borrowed shares. The ratio is used by both fundamental and technical traders to identify trends.

The percentage represents the number of days it takes short sellers on average to repurchase all the borrowed shares. Short selling is the practice of selling securities or other financial instruments that are not currently owned, and subsequently repurchasing them. In the event of an interim price decline, the short seller profits, since the cost of (re)purchase is less than the proceeds received upon the initial (short) sale. Conversely, the short position closes out at a loss if the price of a shorted instrument rises prior to repurchase. A high short ratio can be an indicator that there will be some buying pressure on the security that would increase its price.
