According to OTC:

Short Interest is the total number of shares of a security that have been sold short by customers and securities firms that have not been repurchased to settle short positions in the market. Short selling is the selling of a security that the seller does not own, or any sale that is completed by the delivery of a security borrowed by the seller. Short selling is a legitimate trading strategy. Short sellers assume the risk that they will be able to buy the stock at a more favorable price than the price at which they sold short.
