It happened on 1st Feb with POLY - amazing to watch:
'A short squeeze is an unusual condition that triggers rapidly rising prices in a stock or other tradable security. It occurs when a security has a significant amount of short sellers, meaning lots of investors are betting on its price falling. The short squeeze begins when the price jumps higher unexpectedly and gains momentum as a significant measure of the short sellers decide to cut losses and exit their positions.'
