About Steven Leonard Chapman's insider trades
Steven Leonard Chapman is CEO and President at Natera (NTRA). Since Mar 26, 2018, Steven has reported no open-market purchases and 161 sales worth $256.6M on SEC Form 4. In the last 12 months: 15 sales ($60.3M).
102 sales (75% 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 option exercises (112 filings), grants and awards (17 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 NTRA insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
