A normal DCF asks: given my growth assumption, what is the business worth? The reverse DCF flips it: given today's price, what growth must the business deliver? Instead of arguing about your assumptions, it exposes the market's.
Say a stock's price implies 29% annual free-cash-flow growth for five years, while the company has historically grown 6%. The price is a bet that something has profoundly changed. Maybe it has. But now the question is concrete (“do I believe this specific thing?”) instead of vague (“is it overvalued?”).
In an expensive market this is the sharpest tool in the box, which is exactly why it's the flagship model here and on our MCP server for AI agents. Same engine, same auditable assumptions, run backwards.
