## Definition

FOMO stands for fear of missing out. It is the urge to chase an asset that has already risen sharply, on the worry that the move will continue without you.

FOMO buyers tend to enter near local tops and sell near local bottoms, which is the opposite of what works over time. Good risk discipline, like fixed position sizes and pre-decided rules, is the standard defence.
