High Short Interest Stocks

HighShortInterest.com provides a convenient sorted database of stocks which have a short interest of over 20 percent. Additional key data such as the float, number of outstanding shares, and company industry is displayed. Data is presented for the Nasdaq Stock Market, the New York Stock Exchange, and the American Stock Exchange. You can view the data for all exchanges together or only view exchanges of interest by clicking on the appropriate tab.

Stocks with high short interest are often very volatile and are well known for making explosive upside moves (known as a short squeeze). Stock traders will often flock to such stocks for no reason other than the fact that they have a high short interest and the price can potentially move up very quickly as traders with open short positions move to cover.

Disclaimer: We have made our best effort to provide accurate data, but always do your own research and double check the information presented here before making an investment.
