DCF Valuation (Discounted Cash Flow) and the Dividend Discount Model are two core methods analysts use to estimate a company's intrinsic value. DCF values a business based on all its projected free cash flows — whether distributed to shareholders or reinvested — while DDM values a company based solely on the dividends it's expected to pay out.
Investors compare the two because the right valuation method depends heavily on the type of company being analyzed: applying DDM to a company that pays no dividends, or ignoring reinvested cash flow with a growth company, can produce badly misleading results.
