Economic Moat
Evidence of durable competitive advantage in the filed financials (6 years of history).
Profit margins and economic moats, explainedThe filed history looks like a business competitors struggle to attack: high and steady margins, revenue that grows through cycles, and strong returns on capital.
72.7% average over the last 3 years
±0.6 pts around 72.6% across 6 years
grew in 5 of the last 5 year-over-year periods

A moat can't be proven by numbers alone — this scores the evidence a durable advantage leaves behind (pricing power, consistency, returns on capital), computed the same way for every stock. Pair it with the business overview before concluding anything.

Educational scenario model, not a forecast or investment advice. It starts from the latest annual revenue in SEC filings. By default, growth is trailing revenue growth (held between 3% and 45% a year), the net margin is the latest one (held between 3% and 50%, so a loss-making company is modeled with a small profit), and the Base case P/E runs from 60% to 100% of today's. Carrying recent growth forward five years can miss badly in either direction. Outputs are only as good as the assumptions. Growth, margin or P/E data is missing for this stock, so some starting values above are placeholders rather than measurements.
Key Risks
Market risk — sector rotation, the economic cycle, and broad sentiment move the stock regardless of fundamentals.

DUOL — frequently asked questions
Is DUOL a good stock to buy?
We don't give buy or sell advice. Review Duolingo Inc's fundamentals, valuation, and 5-year financials on this page, then make your own decision — and consider a licensed professional.
Where does DUOL's data come from?
Live price data plus the annual financials in Duolingo Inc's SEC filings, refreshed automatically. Its fundamentals ratios aren't loaded yet, which is why it has no model rating.
How is the 5-year projection for DUOL calculated?
It's a scenario model. It starts from the latest annual revenue and net margin in SEC filings, grows revenue at an assumed rate (trailing revenue growth by default), and applies a P/E range built around today's multiple to show the resulting share-price range. When a stock has no growth or P/E data, the starting values are placeholders. It's a tool for thinking, not a prediction.
