About Keith R Larson's insider trades

Keith R Larson is a director at NWPX Infrastructure (NWPX). Since Jul 28, 2008, Keith has reported 2 open-market purchases worth $99K and 26 sales worth $1.7M on SEC Form 4. In the last 12 months: 2 buys ($99K) and 9 sales ($753K).

25 sales (75% 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 (23 filings), option exercises (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 NWPX insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
