Duolingo, Inc. (DUOL) Stock Sinks As Market Gains: Here's Why

Duolingo (DUOL) stock recently declined 1.69% to $306.73, underperforming broader market gains, as the company prepares to announce its Q3 2025 earnings on November 5, 2025. Analysts project robust year-over-year growth, with EPS estimated at $0.72 (+46.94%) and revenue at $260.52 million (+35.27%), contributing to a Zacks Rank of #2 (Buy) and recent upward estimate revisions.
