Buying stocks requires a lot of patience, if you don't want to get trapped, just obediently wait.
Rebound is for survival, not for buying. Don't let the news lead you by the nose, pay attention to price and technical analysis to determine when to make purchases. Refer to the last downtrend, you may find a useful pattern. If you can't find one, wait for the bottom to form before slowly buying. Really, don't try to time the market at the lowest point.
