About Joseph John Corso's insider trades
Joseph John Corso is Chief Financial Officer at Nlight (LASR). Since Dec 1, 2023, Joseph has reported no open-market purchases and 17 sales worth $14.6M on SEC Form 4. In the last 12 months: 6 sales ($11.1M).
12 sales (70% of the value sold) were made under a Rule 10b5-1 trading plan, which is set up months in advance and runs on a schedule, so they say little about how the insider sees the stock today.
Their filings also include shares withheld for taxes (15 filings), grants and awards (14 filings). 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 LASR insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
