Reverse DCF — What the Price Implies
The inversion
A forward DCF takes assumptions to a value; a reverse DCF takes the market's value to the assumptions. Mechanically: find the 5-year FCF growth (and fade) that makes the model's per-share value equal today's price. The output reframes every debate: not "is AAPL worth $316?" but "AAPL at $316 requires roughly X% FCF growth fading to Y% — do I believe that?" You no longer argue with the market; you interrogate the specific bet it is making.
Why it defeats narrative capture
Stories arrive pre-validated: "AI leader," "platform compounder." Reverse DCF converts the story into numbers you can check against history — no company in the S&P 500 has compounded FCF at 25% for a decade; very few at 20%. If the price requires 22%, you are not buying a great company, you are underwriting a historical anomaly. The tool's grid plus a little iteration does this in minutes: find the growth where the model cell equals price.
Worked example, live
Take the panel's AAPL settings: at $316 live, with WACC 8.87% and g 2.5%, the model needs FCF growth well above the default 8% fade 3% — roughly low-teens growth sustained five years, then perpetuity at 2.5%, to reach price. Now the historical check: Apple's FCF has compounded ~10–12% over its best recent decade with buybacks doing heavy per-share lifting. The price is paying for the top of Apple's own historical range, continuing forever. Whether that is rational is exactly the question you should now be able to ask precisely.
Find g such that DCF(g) = Market Price
Reverse DCF — The panel + grid solve this by inspection: locate the cell equal to price, read its growth assumption.
Cisco 2000, revisited properly
In March 2000 Cisco traded at ~$555B market cap on ~$3B of FCF — the price implied roughly 30%+ FCF growth for a decade plus a premium terminal multiple. Run that against history: nothing that size had ever done it. The reverse calculation was public, simple, and devastating — and almost nobody ran it, because the forward story (internet builds itself) was more fun. Six months later: −40%. Twenty years: still below the peak. The tool that would have saved you fits in one lesson.
