The sum of the short sales in a security, commodity, etc., or on an exchange, which have not been covered as of a given date.
A measure of the number of short-selling positions on a stock or futures exchange. The number of short interest positions is a barometer for the bearishness of the market. If the number of short interest positions rises, more people are expecting a downturn. The New York Stock Exchange (NYSE) publishes a monthly report on short interest, while futures positions are reported bi-weekly by the Commodity Futures Trading Commission (CFTC).
