Short interest is the number of shares sold short and not yet bought back on the settlement date. The percent of shares uses today's shares outstanding (a float figure is not available), and the value short uses today's price, so both are estimates. Ranking by days to cover only counts stocks with an average daily volume of at least 10,000 shares. Market cap and price are in the trading currency.

Days to cover is the short interest divided by the average daily trading volume. It shows how many trading days it would take short sellers to buy back all their shares at the usual volume. A higher number means a short position is harder to close.
