Short interest is the number of shares sold short and not yet bought back. Brokers report it to FINRA for two settlement dates a month, the middle and the end, and FINRA publishes each count about a week later. It is not a daily figure: between settlements no one publishes a count. Days to cover is the short interest divided by the average daily volume FINRA reports beside it. A rising count is shown in red and a falling one in green.
