FOMO (Fear Of Missing Out)
The anxiety that you alone will miss the chance, leading to late chase-buying — the emotion that typically lifts the final stage of a bubble.
FOMO = the crowd psychology of belatedly buying an already sharply risen asset out of the fear "everyone but me is making money"
FOMO peaks when an asset surges and the mood spreads that "if you don't buy now, you'll regret it forever.
In plain terms
FOMO stands for "Fear Of Missing Out" — the feeling of being afraid that you alone will miss a good chance. When you hear that others made money on some stock or coin, the worry about falling behind makes you rush in and buy along with them.
The issue is that by the time you chase in like that, the price has usually already risen a lot. So buying swept up in FOMO can easily leave you stuck at a peak.
What it tells you
FOMO is the emotion that lifts the final stage of a market bubble. When people crowd in with the urgency of "this is the last chance," that is, paradoxically, often the riskiest moment.
What this expression points to is a state where the reason for buying is "because others made money."
Formula
FOMO = the crowd psychology of belatedly buying an already sharply risen asset out of the fear "everyone but me is making money"
What high or low means
FOMO peaks when an asset surges and the mood spreads that "if you don't buy now, you'll regret it forever." That mood itself is sometimes read as a sign of overheating.
Once the money that came in on FOMO starts to leave, those who chased in at the end often take the largest losses.
Buying while swept up in FOMO skips the judgment of "why am I buying this?" Seeing others make money and understanding a company's value are two different grounds. (This is a concept explanation, not a trading suggestion.)
On the other hand, saying "FOMO is always bad" is also a sweeping claim. The mere fact that something is rising tells you nothing about that company's earnings or finances.
