To sell short is to sell shares that you do not own with the hope that the shares decline in value and can be purchased in the future at a lower price to cover the trade and make a profit
Short interest is a count of shares that have been sold short. This is reported on the 15th and last day of the month.
The Short Interest Ratio is the number of shares sold short/ average daily trading volume – this is also known as Days to Cover.
