The strongest recent filing
von Ahn Luis (President) sold 53,640 shares of Duolingo, Inc. on Feb 17, 2026, a filing that scored 89 (Strong). It scored Strong because a senior insider was trading and several insiders moved the same way within a week. The score describes the filing, not future returns. This is not investment advice.
Cluster activity
A cluster buy is present: 6 insiders (Skaruppa Matthew, Chen Stephen C., Glance Natalie, Meese Robert) traded DUOL the same direction within a 7-day window. Shared conviction is a stronger structural signal than a lone trade.
How this compares with Duolingo, Inc.'s own history
Open-market buys make up 26% of the 74 scoreable DUOL transactions on record between Dec 1, 2025 and Oct 10, 2026. Comparing a filing with the company's own buy/sell mix is how you tell a routine disposal from an unusual accumulation.
Methodology and sources
Scores come from six published, user-adjustable factors (insider role, cluster activity, trade size versus the insider's own history, position impact, filing urgency, and direct versus indirect ownership). The score describes the filing, not future returns. This is not investment advice.
