Graham's parable
"You are neither right nor wrong because the crowd disagrees with you. You are right because your data and reasoning are right." - The Intelligent Investor, Ch. 8
"The true investor scarcely ever is forced to sell his shares, and at all other times he is free to disregard the current price quotation." - The Intelligent Investor, Ch. 8
Mr. Market shows up daily with a bid and ask. Your job is to buy only when his price is attractive and to ignore him otherwise.
How to use Mr. Market
- Anchor to intrinsic value; treat quotes as offers.
- Pre-set buy ranges at discounts and sell ranges at premiums.
- Do nothing between those ranges; inaction is a valid decision.
- Keep cash ready so you can act when Mr. Market is depressed.
Behaviors to avoid
- Selling just because price fell without value deterioration.
- Chasing price rises without updated value work.
- Letting volatility dictate thesis changes.
- Using leverage that can force sales when prices swing.
Simple playbook
- Maintain your own value estimates and update with filings.
- Post limit orders where margin of safety exists.
- Ignore daily price noise; focus on fundamentals cadence (quarters, filings, catalysts).
- Track why you bought; exit when value closes to price or thesis breaks.
Takeaways
- Mr. Market is a servant, not a guide.
- Volatility is a source of opportunity, not fear, when you have your own value.
- Patience and cash are key tools for using Mr. Market intelligently.
