Short interest ratio
Short interest is a measure that denotes the number of shares sold short for a given span of time. Stock exchanges prepare a monthly report on the total amount of short interest in a particular stock. A short interest ratio indicates the number of days it takes for short-sellers to cover their positions.
The industry sentiment is divided when it comes to evaluating the impact of the short interest ratio. Many consider it to be an indicator of bearish sentiment while others believe high short interest ratios are more likely to increase prices in the future when short sellers buy to cover up their positions.
