GLOSSARY // Risk & Psychology
FOMO
FOMO — fear of missing out — is the urge to buy a stock because it is already running and everyone else seems to be getting paid. The entry is driven by the pain of watching, not by a setup, which is why FOMO buys cluster near short-term tops.
The structural problem is location: by the time a move is obvious enough to create FOMO, the low-risk entry is far behind, the logical stop is far below, and the risk-reward ratio has inverted. The same stock can be a good trade at the breakout and a bad trade 30% higher — price paid, not the ticker, decides which.
A stock breaks out at $10.00 and a disciplined entry there risks $0.60 against a $12 target — 1:3.3. By 11am it prints $14.00, up 40%, and the FOMO buyer enters with the nearest logical support at $12.20. They now risk $1.80 to make what is left of an extended move. Two of these chases at 200 shares cost $720 in stop-outs while the breakout buyer is still holding from $10.
