Fear of Missing Out
The anxiety of being left out of a rise that others are participating in, leading to purchases made without analysis.
How it is identified
Test: the decision to buy is triggered by others' gains rather than by any assessment of the asset's value
Unit
qualitative
In depth
FOMO is loss aversion applied to a gain not taken: missing a rise is experienced as a loss, which is why it produces urgency out of proportion to the opportunity. It is amplified by visible social comparison, which is why it has intensified as trading became social — everyone posts gains and nobody posts losses, so the observable sample is systematically distorted. Its characteristic signature is buying without doing work that would have been considered necessary a week earlier. The countermeasure is a pre-committed process: a rule that no position is taken without a written thesis and a defined exit removes the ability to act on the impulse.
Worked example
A stock rises 140% in three months and an investor buys at the top of that move, having done no analysis. The 140% was available to someone else; the position taken is a new decision at a new price with none of that return.
