About Jonathan M Rothberg's insider trades
Jonathan M Rothberg is a director at Butterfly Network (BFLY). Since Dec 11, 2006, Jonathan has reported 8 open-market purchases worth $1.0M and 31 sales worth $87.6M on SEC Form 4. In the last 12 months: 23 sales ($74.6M).
5 sales (13% 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 grants and awards (21 filings), other transactions (3 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 BFLY insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
