Buying stocks requires patience, and you don't want to be caught waiting.
A bounce is an escape, not a buy, don't let the news carry your nose, let the price tech talk. You know when to buy, refer to the next drop, you may find a useful pattern, you can find a useful pattern, just wait until the bottom is formed, buy slowly first. It's really good to stay on the left to buy the lowest point.
