Value Investing: Estimating Intrinsic Value and Applying a Margin of Safety
Summary
The article presents value investing as buying shares below an estimate of their intrinsic worth, with the gap between estimated value and purchase price serving as a margin of safety. It describes selling when price approaches or exceeds estimated value and contrasts this long-term, valuation-led approach with short-term trading driven by price trends or market sentiment. Examples include market-wide sell-offs and company-specific news, illustrating that a sharp decline alone does not make a stock attractive; the investor must judge how events affect future business prospects.
It introduces Benjamin Graham’s earnings-and-growth valuation formula, including a revision that adjusts for bond yields, and suggests peer comparisons, insider activity, discounted cash flow, earnings per share, and price-to-earnings ratios as inputs or checks. The article gives historical stock-return examples but does not establish that the strategy caused those returns. Intrinsic value and growth assumptions are subjective, valuation requires research, and investors may need patience while price converges toward estimated worth.
Key ideas
- Value investors seek companies priced below an estimate of their intrinsic worth.
- The difference between estimated worth and purchase price is intended to provide a margin of safety.
- A price decline is not sufficient evidence of undervaluation; its causes and effects on future prospects need assessment.
- Graham’s formula combines earnings and expected growth, with a revision that incorporates bond yields.
- Peer comparisons and financial ratios can support valuation, but growth estimates and intrinsic value remain uncertain.
