Moderna stock jumped 130% in a single session. That's not normal market behavior — it's either a short squeeze, a massive buyout rumor, a Phase 3 trial miracle, or some kind of technical glitch.

Whatever the reason, this is a reminder: when a stock moves like this, the people making money are the ones who bought before the move, not the ones chasing it after.

If you're tempted to jump in now, ask yourself: do you know something the market doesn't, or are you just reacting to a number on a screen?

Volatility creates opportunity, but it also creates bagholders. Don't confuse excitement with edge.
