  1. Short interest is the number of shares investors have borrowed and sold, betting the price will fall, and not yet bought back.
  2. Days to cover is shares short over an average day's trading: how many days it would take short sellers to buy them all back. Above 5 or so is high.
  3. Rising short interest says more investors are betting against the stock. A crowded short can also rise fast if shorts rush to buy back.
  4. Brokers report it twice a month to FINRA, about ten days after each settlement date.
  5. What is short interest?

How it compares

every company on the site

    The bar ranks every company on the site from the lowest on the left to the highest on the right, in three equal thirds; the small figures under it are the values where each third starts, and the black tick is the middle company. The orange dot is this company; the grey ticks are the other companies in its industry (hover or tap for names). A hatched block is companies tied at none.
