FOMO

Also called: fear of missing out

Fear Of Missing Out — the urge to chase a move that's already running, usually resulting in buying the top or shorting the bottom.

FOMO is the emotional reaction of seeing a big move happen without you and feeling like you have to get in NOW or miss it forever. In trading, FOMO is the reason people buy right at the top of a rally or short right at the bottom of a crash. By the time you feel FOMO, the move is usually 80% done. FOMO is a brain chemistry thing. Seeing something go up fast triggers a dopamine-craving reflex — your brain thinks "free money" and wants a hit. That reflex overrides your trading plan and your risk rules. You enter without a stop, oversized, at a terrible price. The antidote is simple: if you weren't in before the move started, you're not in. Wait for the next setup. There's always another trade.

Real trade example

The Apr 2024 Gold breakout above $2,400 sucked in massive FOMO buying at $2,450. Gold then retraced to $2,280 over the next month before resuming the uptrend. FOMO buyers got crushed on the retrace.
