Mr. Market: your moody business partner
Imagine you own a private business with a partner named Mr. Market. Every day, he offers to buy your share or sell you his. Some days he is euphoric and offers absurdly high prices. Other days he is depressed and will sell for almost nothing.
You are never obligated to trade with him
The key insight: you are not obligated to trade with Mr. Market. His mood swings are your opportunity, not your guide. If his price is too high, sell to him. If too low, buy from him. If neither, do nothing.
How to respond to each of Mr. Market's moods
| Mr. Market Is... | He Offers... | Smart Investor Does... |
|---|---|---|
| Euphoric (greedy) | To buy at absurd premiums | Sells or holds |
| Rational | Fair prices | Does nothing |
| Depressed (fearful) | To sell at deep discounts | Buys more |

Where to practice the Mr. Market mindset
For applied practice, the Personal Finance & Value Investing course works this same framework through real scenarios in its Businesses, Not Tickers and Intrinsic Value vs. Price modules (pfvi-8, pfvi-9).
Sit with the ideas.
A high-quality company with growing earnings and strong cash flow drops 25% in two weeks because the overall market is in a panic about interest rates. The company has no debt. What would Benjamin Graham likely say?
