What is discounted cash flow (DCF) valuation?
By Mehmet Saruhan, Founder·
Discounted cash flow (DCF) valuation estimates what a business is worth today by forecasting the free cash flow it will generate, discounting each year's cash to the present at a rate that reflects its risk, usually the weighted average cost of capital (WACC), and adding a terminal value for the years beyond the forecast.
Why it matters
A DCF turns a price into a question: what would have to be true about future cash flows for this price to be fair? It makes every assumption explicit, so each one can be argued with. Its weakness comes from the same place: most of the value usually sits in the terminal value, so small changes in the discount rate or in long-run growth move the answer a lot.
How it works
The idea that a security is worth the present value of its future cash goes back to Williams (1938). Free cash flow is projected for five to ten years and discounted at the WACC: the cost of equity, usually from the CAPM (risk-free rate plus beta times the equity risk premium; Sharpe, 1964), blended with the after-tax cost of debt at market-value weights. The terminal value is typically a growing perpetuity, next year's cash flow divided by (WACC − g) (Gordon, 1959). Net debt is subtracted and the result divided by the share count.
How Opulence Alpha applies it
Opulence Alpha does not publish a DCF on its own. Its Intrinsic Value model, recomputed every US trading day from point-in-time filings, uses a cash-flow valuation as one of three methods, blended with a residual-income valuation and the median multiples of industry peers; the stock's own price is never an input. Discount rates are observable: the 10-year Treasury yield plus that day's market-implied equity risk premium, the stock's beta and its credit spread. Banks, insurers and REITs use their own methods. The published range is a model range, not a calibrated interval, and the estimate is not a price target.

Questions
Why is a DCF so sensitive to its assumptions?
- Because the terminal value usually carries most of the result, and it depends on the gap between the discount rate and long-run growth. With 3% long-run growth, a 9% discount rate values the years beyond the forecast at about 17 times the following year's cash flow; at 8% it is 20 times. Cutting the discount rate by one point raises that part of the value by a fifth.
Is a DCF intrinsic value the same as a price target?
- No. A DCF intrinsic value is what the cash flows are worth under stated assumptions; it says nothing about when, or whether, the price will get there. A stock can be genuinely undervalued and keep falling for a year. Opulence Alpha publishes its intrinsic values as a model's estimate, not a price target and not a recommendation to buy or sell.
Why run Monte Carlo scenarios on a DCF?
- Because a single DCF hides how uncertain its inputs are. Drawing growth, the discount rate and terminal growth many times turns one number into a distribution and shows how wide the plausible range is. Opulence Alpha runs 10,000 scenarios per company, with correlated, fat-tailed draws, and records the range from the 5th to the 95th percentile around the central value.
