About Gregory W Schafer's insider trades
Gregory W Schafer is Chief Operating Officer at Aduro Biotech (ADRO). Since Aug 11, 2006, Gregory has reported 2 open-market purchases worth $34K and 16 sales worth $5.8M on SEC Form 4. There have been no open-market trades in the last 12 months.
2 sales (6% 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 (16 filings), grants and awards (16 filings), conversions (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 ADRO insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
