About Stephen C. Chen's insider trades
Stephen C. Chen is General Counsel at Duolingo (DUOL). Since Nov 15, 2021, Stephen has reported no open-market purchases and 32 sales worth $28.8M on SEC Form 4. In the last 12 months: 6 sales ($3.1M).
1 sale (1% of the value sold) was made under a Rule 10b5-1 trading plan, which is set up months in advance and runs on a schedule, so it says little about how the insider sees the stock today.
Their filings also include option exercises (17 filings), grants and awards (7 filings), gifts (1 filing). These aren't open-market trades and aren't counted above.
How to read insider trades
Officers, directors and owners of more than 10% of a company must report trades in its stock on SEC Form 4, usually within two business days. Purchases with their own money are the stronger signal: insiders sell for many reasons (taxes, diversification, a house), but buy for one. See every DUOL insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
