Squeeze Ideas: 3 Oversold Biotech Stocks With Increasing Short Interest

 |  Includes: CBIO, CORT, OPTR
by: Kapitall

If a stock becomes highly shorted and oversold, a short squeeze may occur in which a bump up in stock price forces short sellers to close their positions, adding even more upward momentum to the stock price and causing even more short sellers to close their positions. The key is to determine when short selling hits an extreme.

Following this idea, we ran a screen on biotech stocks for those that are technically oversold [with RSI (14) below 40] and have also seen significant increases in shares shorted month-over-month.
