You'll at least perform decently if you just keep the "Bul-Ban-Kkul" in mind.

Of course, it is true that there are several top-tier experts in the bullpen, but
if you simply judge by doing the opposite of the majority of "moths" who react emotionally to every minor fluctuation,
you will at least perform decently.
True beginner stock investors on Bulpener must not forget this.
Bul-Ban-Kkul!!!
