P/E — fast, intuitive, best for stable earners

DCF — first-principles, most flexible, most assumption-heavy

FCF & OCF — value the cash, not the accounting

Frequently asked questions

When should I use DCF instead of a P/E multiple?

Use DCF when you can reasonably forecast cash flows and want an intrinsic value anchored to fundamentals. Use P/E for quick relative comparisons — especially for profitable, mature companies — where precision matters less than speed.

Which stock valuation method is most accurate?

None is accurate on its own; each answers a different question. Professionals triangulate: P/E for relative pricing, DCF for intrinsic value, and FCF/OCF yields as a reality check on cash. Agreement across methods is worth more than precision in any one.

What is a reverse DCF?

A reverse DCF works backwards: instead of estimating value from assumed growth, it solves for the growth rate the current stock price already implies. If the implied growth looks unrealistic versus history, the stock is likely overvalued.
