About Arve Hanstveit's insider trades
Arve Hanstveit is a director at Energy Recovery (ERII). Since Jul 8, 2008, Arve has reported 1 open-market purchase worth $415K and 38 sales worth $19.6M on SEC Form 4. In the last 12 months: 4 sales ($2.7M).
4 sales (10% 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 (16 filings), option exercises (7 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 ERII insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
