Many of the most heavily shorted stocks that trade on the Nasdaq hail from the financial sector; however, other sectors such as health care and manufacturing are also represented.
A heavily shorted stock can move sharply upward on any positive catalyst as short-sellers are forced to scramble to cover their bearish positions. A stock's short interest is measured by the short ratio, which represents the number of days it would take those shorting the stock to cover their bearish bets, based on recent trading volume.
