Short-Interest Ratio
The short-interest ratio is the number of shares sold short (short interest) divided by average daily volume. This is often called the "days-to-cover ratio" because it tells, given the stock's average trading volume, how many days it will take short sellers to cover their positions if positive news about the company lifts the price.

Again, let's assume Microsoft has a short interest of 75 million shares, while the average daily volume of shares traded is 70 million. Doing a quick and easy calculation (75,000,000/70,000,000) we find that it would take 1.07 days for all of the short sellers to cover their positions. The higher the ratio, the longer it will take to buy back the borrowed shares - an important factor upon which traders or investors decide whether to take a short position. Typically, if the days to cover stretch past eight or more days, covering a short position could prove difficult
