That was called a dead cat bounce!
A dead cat bounce is a small, short-lived recovery in the price of a declining security, such as a stock. Frequently, downtrends are interrupted by brief periods of recovery - or small rallies - where prices temporarily rise. This can be a result of traders or investors closing out short positions or buying on the assumption that the security has reached a bottom. A dead cat bounce is a price pattern that is usually identified in hindsight. Analysts may attempt to predict that the recovery will be only temporary by using certain technical and fundamental analysis tools.
