About Brian M Stuglik's insider trades
Brian M Stuglik is a director at Puma Biotechnology (PBYI). Since Sep 28, 2018, Brian has reported 1 open-market purchase worth $7K and 28 sales worth $396K on SEC Form 4. In the last 12 months: 2 sales ($64K).
1 sale (9% 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 grants and awards (22 filings), shares returned to the company (1 filing), shares withheld for taxes (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 PBYI insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
