FOMO

In plain English

FOMO is the fear of missing out — the urge to buy because everyone else seems to be winning. It often leads to chasing after the easy move is gone.

Everyday analogy: Joining a long nightclub line just because it’s long — not because you checked what’s inside.

Why it matters

FOMO is how bull markets empty discipline. A written entry rule is cheaper than a late chase.

A bit more detail (optional)

How it shows up

Buying strength late, abandoning rules, and sizing up because “everyone else is winning” are classic FOMO tells.

Antidote

Write the thesis, max size, and invalidation before the green candle hits. A checklist beats improvisation.

Simple examples

Chase checklist

If you cannot write a one-sentence thesis and an exit rule, you are probably chasing — not investing.

Chase checklist

Before buying a runaway name, write: thesis in one sentence, max size, and the fact or price that proves you wrong. If you cannot, wait.

Easy mistakes to avoid

  • Sizing up because a name is already extended
  • Abandoning a watchlist process after a green candle
  • Confusing social proof with a thesis

Remember: Write the plan before the emotion arrives.
