When the fool has made up his mind, the market is over.

Understand the thought

Meaning in plain English

A fool deciding only after the market ends gives delayed judgment an image of a missed opportunity. The saying asks whether indecision has practical costs.

What the words are saying

A critical reading rejects the insult as proof of a person’s intelligence and does not assume every delay is avoidable. A useful application checks real timing and what information is needed. Pressure should not replace understanding, and some choices should be postponed despite a closing opportunity.

Everyday example

Someone checks a genuine deadline and gathers the information needed for a timely decision.

When to use it

Use it to discuss timing without manufactured urgency or blame.
