The sales occurred during a period of significant momentum: the stock is up 59.3% over the prior 30 days and up 17.9% over 90 days, trading near its 52-week high of $540.68. Chen's prior trades at DUOL show a timing pattern of 0 of 4 measurable outcomes well-timed at the 90-day mark, with the most recent sale on 2025-05-15 preceding this filing. The company trades at a P/E of 89.54 on strong fundamentals ($230.7M quarterly revenue, +40.8% annual growth, $35.1M net income). This sale is notable not for its size relative to his remaining holdings but for its execution during a sharp near-term rally following a prolonged underperformance period earlier in the year.

General Counsel Chen sold 1,257 shares of DUOL at $531.71; retains 38,820 shares. Stock near 52-week high.

Chen Stephen C. (General Counsel) executed a modest sale of 1,257 shares (1.3K shares) on 2025-05-15 at $531.71, representing a -3.1% reduction of his prior holding of 40,077 shares (40.1K shares). The sale occurred near Duolingo's 52-week high of $540.68, with the stock currently trading at $529.05 (only -2.2% from peak). The transaction is notably small in absolute terms—$668,359.47 in total value—relative to his substantial remaining stake of 38,820 shares. Cross-ticker history shows his prior 20 open-market sells returned an average +9.6% over 30 days and +46.6% over 90 days, with a 0.00% well-timed rate (0 of 20 sells preceded declines), suggesting a consistent pattern of selling before upswings rather than exits timed to downturns. The company exhibits strong fundamentals (Revenue $230.7M, Net income $35.1M, +40.8% annual revenue growth, Market cap $8.8B) offset by an elevated valuation (P/E of 91.06).

Duolingo General Counsel Chen sells 2,064 shares ($898.1K) near 52-week high; prior DUOL trades all underperformed post-sale

Chen Stephen C., General Counsel of Duolingo, executed 2 separate sales on 2025-02-18, totaling 2,064 shares (2.1K shares) for $898,091.44 ($898.1K) at a blended average price of $435.12, reducing holdings by 5.6% from 36,698 to 34,634 shares. The transaction occurred near the stock's 52-week high of $441.39 (current price $432.52 is -2.0% from that peak), following a strong 30-day rally of +23.2% and 90-day advance of +26.6%. Notably, across his 5 prior trades at Duolingo (all in 2024), all resulted in positive 90-day returns (+38.6% to +66.7%), with 0 of 5 being well-timed (meaning the stock rose after each sale, indicating the insider sold before gains rather than before declines). The stock trades at a P/E of 83.02 with recent quarterly net income of $23.4M on $192.6M revenue, underscoring a high valuation profile despite strong +43.7% annual revenue growth. This sale pattern at an elevated price point, coupled with consistent failure to sell ahead of pullbacks in prior Duolingo transactions, suggests opportunistic activity rather than a signal of deteriorating fundamentals or conviction.

Chen Stephen C. (General Counsel) sold 2,642 shares for $814,966.70 at blended average price $308.47 on 2024-11-18.

Chen executed 4 separate sales totaling 2,642 shares for $814,966.70, reducing his DUOL holdings by 7.7% from 34,309 to 31,667 shares. The transaction occurred while the stock traded near its 52-week high of $331.14 (current price), after a 15.0% gain over the past 30 days and 58.7% gain over 90 days. His prior sales at DUOL on 2024-08-30 all registered strong 30-day returns ranging from 30.3% to 33.3%, though outcome measurement at the 90-day horizon is not yet available for those trades. This sale follows a pattern of regular dispositions at the ticker without a measured history of well-timed exits at the 90-day mark.

Chen (General Counsel) sold 19.5K shares for $4.1M on 2024-08-30; current price $206.36 is 17.1% below 52-week high of $248.84.

Stephen C. Chen, General Counsel, executed 6 separate sales totaling 19,464 shares for $4,117,674.22 on 2024-08-30, reducing his holdings by 35.4% from 55,022 to 35,558 shares. The blended average transaction price of $211.55 sits only 2.5% above the current price of $206.36, suggesting the sales occurred near current valuation rather than at a significant premium. However, Chen's prior 5 open-market sales at DUOL (all on 2024-01-04) showed inconsistent timing: all five produced negative 30-day returns ranging from -12.8% to -14.9%, yet all five posted positive 90-day returns ranging from +4.6% to +7.2%, with 0 of 5 ranked well-timed at the 90-day mark. This pattern—immediate post-sale weakness followed by recovery—repeats the January timing profile. The stock has gained 27.4% over the past 30 days, suggesting the market has moved substantially since these late-August sales, making a near-term assessment of this transaction's timing premature.
