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.

Fails to deliver are the shares sellers had not delivered by the settlement date, a balance outstanding on each date, from the SEC’s fails-to-deliver files, published twice a month about two weeks after each half-month ends. The value is the shares times that day’s closing price in the same file. Every security’s fails.

The cost to borrow is Interactive Brokers’ own yearly fee to borrow the stock and the shares it has left to lend, from the file it publishes about every 15 minutes; a weekday’s last read stands for that day. It is one broker’s figure; another’s can differ. The hardest stocks to borrow.

Filings to sell shares are the company’s prospectuses for shares, shelf and other registrations, and 8-Ks reporting a private sale, from the SEC’s daily index of filings, each cover read so that bond offerings are left out. Each form links to the filing. Every listed company that filed.
