Seizing the opportunity?

Seizing the opportunity? I think this is more like gambling.

During the earnings season, the stock prices of some stocks often experience huge fluctuations. If we bet on the right direction, then we will fly to the moon.On the contrary, if we bet on the wrong direction, it will be a bottomless pit.I have to admit that my luck in gambling seems to be bad, so I usually do not participate in real betting gambling. I have failed several times in predicting the target price events. (Attention @Moo Earnings participate in the earnings forecast target price event)

Looking for opportunities!
When it comes to paying more attention to stocks, usually I hope to see financial reports of the stocks I follow or buy not meeting the expected target, as this will provide me with more buying opportunities.
Usually, some good value stocks have prices that are too high, for example. $Apple (AAPL.US)$ ， $Amazon (AMZN.US)$ Some economic factors affecting stock financial data not meeting expectations leading to a decrease in stock prices, this is an excellent entry opportunity.
As for stocks exceeding expectations leading to stock price increases, I think I might sell some stocks at that time.
