I’m not great at this, and I still have a ton to learn. But YMAT paid me nicely today, and it’s not a one-off. I’m starting to recognize a pattern in my own trading: when I stay disciplined, wait for my setup, manage my risk and take the profit I planned, I tend to do well. When I get impatient, chase, or let FOMO make the decision, that’s when I lose.
If you're treating penny stocks like lottery tickets, you're gambling. If you're trading them, risk management and execution matter more than being right about the story. I’m still learning that lesson every damn day.
