FOMO
Fear of Missing Out — the emotional state in which an investor buys an asset near the top of a rally out of fear of "missing the move," which often leads to losses.
How it works
The fear of missing out is a state in which a decision comes not from analysis but from watching price rise without you. A person buys not because they assessed the asset but because they are afraid of being left behind.
The mechanism is amplified by feedback: rising prices produce headlines, headlines bring new buyers, buying pushes price further. Each turn feels like more evidence of being right, though all that grows is the speed.
One simple test separates this state from a reasoned decision: if you could not have explained why you wanted this asset a week ago at the same price, you are buying the move rather than the asset.
What it costs
Two entries into the same asset: one to a plan, one on a wave of headlines.
| Planned entry at a pre-chosen price | $1,000 at 40 |
| Entry at peak attention | $1,000 at 95 |
| Price three months later | 55 |
| Outcome of the first | +37% |
| Outcome of the second | −42% |
The asset was identical; only the entry point differed. The 79-point gap in outcome is explained entirely by when the decision was made.
What to do about it
- Decide before the move, not during itAn entry price, position size and exit conditions written down in advance work precisely because they were written in a calm state.
- Split the entryBuying equal amounts on a schedule removes the question of whether this is the top — it deliberately hits neither the best nor the worst point.
- A headline is not a signalBy the time mainstream outlets write about a rally, the move is already in the price. News reports the past, not the future.
