Lessons from chasing $NVDA after a gap-up

Biggest mistake recently was chasing $NVDA after that gap-up post-earnings. Saw the momentum, felt the FOMO, convinced myself it was going to run another 10% easily. Entered with a decent chunk, watched it churn sideways for an hour, then slowly bleed. Didn't honor my initial mental stop because 'it's $NVDA,' then it started accelerating south. Ended up taking a much larger loss than necessary, effectively giving back a week's worth of grind. Realized I violated rule number one: don't chase, especially into extended moves, and always stick to the stop. The emotional attachment to a 'hot stock' definitely clouded judgment.
