A tough lesson on sizing into a rally
One of my costly lessons came from trying to add aggressively into a strong rally, specifically last year with $NVDA. I had a good initial position, but FOMO kicked in hard as it kept pushing. Instead of letting my winners run or just taking profits, I kept increasing my position size on every small dip, effectively averaging up way too much and getting sloppy with my risk management. When the inevitable pullback came, my paper gains evaporated much faster than they accumulated, and I ended up giving back a significant chunk of what should have been a solid winning trade because my size got completely out of control in pursuit of every last cent.
This is such a relatable experience, especially with a stock like NVDA. It's tough when you have a good initial position and then that FOMO kicks in, making you overcomplicate what should be a simple hold or trim.
