Full Analysis
Duolingo (DUOL) shares have declined approximately 54.6% over the past year, prompting investors to question whether the current valuation of roughly $149.92 per share is justified by the company's earnings power.

Simply Wall St analysis suggests that Duolingo appears overvalued based on their Fair Ratio model, which factors in growth potential, margins, and risk profiles. The elevated multiple assumes the company can navigate ongoing legal challenges regarding user growth quality and monetization tactics without a significant reset to its earnings power. Analysts note that the recent sell-off may have priced in some risks, but the premium valuation remains a key debate point. Valuation scenarios presented by analysts diverge significantly.
