You look at the market, it's still rising, feeling anxious and uneasy... It pulled back a little, and your mood eased slightly... But the pullback isn't much, and you're reluctant to buy in... Emotions keep repeating and accumulating (key point)...
They say it's going to rise further;
They say there are still positive factors;
They say the target price is this much;
They say it will rise by this many times...
So, you make a bold move and think, let it be...
Then it officially starts to drop...
Note, this is a general human behavior pattern of the group~
