Largest Increases in Short Interest on 2/28/2017

Shares that are sold "short" are borrowed then sold with the hopes that the share price will drop before the shares that were borrowed have to be repurchased and returned. A large amount of short interest may be an indication that a share price may be ready to decline in the near future. "Short" shares can also serve as a hedge for investors that have purchased a large number of shares of a company thinking that the share price will rise over time. Learn more.
