About Victor K Lee's insider trades

Victor K Lee is an insider at Monolithic Power Systems (MPWR). Since Nov 30, 2012, Victor has reported no open-market purchases and 17 sales worth $7.5M on SEC Form 4. In the last 12 months: 2 sales ($1.0M).

2 sales (14% 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 (27 filings), option exercises (15 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 MPWR insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
