- Short interest is the number of shares investors have borrowed and sold, betting the price will fall, and not yet bought back.
- 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.
- Rising short interest says more investors are betting against the stock. A crowded short can also rise fast if shorts rush to buy back.
- Brokers report it twice a month to FINRA, about ten days after each settlement date.

Bottom: the share price, so you can see whether shorts added as the price fell or rose. Counts before a split are restated to today's shares, the way the price is.
