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.
Investor slang; a brief recovery in the price of a falling stock. Term is derived from the idea that "even a dead cat will bounce if it falls from a great height."
I tried to buy GX on the dead cat bounce but got burned.
