PSYCHOLOGY & BEHAVIOURalso: fear of missing out

FOMO (fear of missing out)

FOMO in trading is entering a position late, after a move is already underway, driven by the fear of missing profit rather than by a setup meeting the trader's criteria.

The structural problem with a FOMO entry is that it is late by definition. Entering after extended movement means a stop placed at any sensible invalidation level is now far away, so the trade carries either an oversized risk or an arbitrarily tight stop that has no analytical basis.

It is amplified by visible social proof. Feeds display the trades that worked and rarely the ones that did not, which creates a persistent impression that everyone else is catching moves you are missing.

A missed opportunity costs nothing. A late entry costs money. These feel similar and are not remotely equivalent.
