About David L Lamp's insider trades
David L Lamp is President and CEO at Northern Tier Energy (NTI). Since Jan 2, 2007, David has reported no open-market purchases and 14 sales worth $8.7M on SEC Form 4. There have been no open-market trades in the last 12 months.
2 sales (4% 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 (32 filings), shares withheld for taxes (21 filings), option exercises (12 filings), shares returned to the company (12 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 NTI insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
