About Joseph P Keithley's insider trades
Joseph P Keithley is a director at Axcelis Technologies (ACLS). Since Jun 16, 2006, Joseph has reported 40 open-market purchases worth $379K and 32 sales worth $7.5M on SEC Form 4. There have been no open-market trades in the last 12 months.
1 sale (1% 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 (90 filings), other transactions (44 filings), option exercises (12 filings), shares returned to the company (8 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 ACLS insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
