dead cat bounce 

Wall Street expression describing the phenomenon of a stock or share bottoming out to near zero and then recovering with a sharp buying spree from bargain hunters: the notion being that even a dead cat will bounce if dropped from a high-enough point.

Your stock prices going up is no more than a dead-cat bounce: it doesn't have the juice to stay up.
