One of the two fundamental fears that drive retail behaviour in VSA. When prices are rising and news is good, uninformed traders rush to buy because they are afraid of missing further gains—providing the liquidity professionals need to distribute their holdings. Every gap-up into new highs on good news, every up-thrust at the end of a rally, and every buying climax is designed to trigger FOMO at precisely the wrong moment for the retail trader. The professional operator does not feel FOMO; he sells into it.
