Popularity is not proof
Others making money is not a reason.

Herd behaviour and FOMO
When everyone seems to be buying something, the fear of missing out can override a plan. Slow down on purpose.
In this lesson you will
- Recognise herd behaviour and FOMO
- Run a quick FOMO checklist
- Cap speculative ideas
People tend to follow what others are doing, especially when uncertain. In money, that can mean buying what is popular after it has already risen, or selling because everyone else is.
Signs of FOMO
- You learned about it from excited posts, not research.
- The main reason is that others made money.
- You feel you must act today.
- You cannot explain how it makes money or what could go wrong.
Why it is costly
By the time something is widely talked about, high expectations may already be in the price. Buying late in a frenzy and selling after the fall is a common pattern.
Slow down on purpose
Use a waiting period for any new investment idea, write down why you are buying and what would make you sell, and limit speculative ideas to a small slice decided in advance.

Answer before acting on a hot idea.
| Question | Red flag answer |
|---|---|
| Where did I hear about it? | Social media hype |
| Why am I buying? | Others made money |
| Can I explain how it makes money? | No |
| What would make me sell? | I do not know |
| How much of my portfolio? | More than my set limit |
Two or more red flags: wait, or skip it.
Where this usually goes wrong
- Buying because prices already soared
- Selling because others panic
- No limit on speculative bets
Set your maximum percentage for speculative ideas and write it down.
