About David Brian Miller's insider trades
David Brian Miller is a director at Onto Innovation (ONTO). Since May 9, 2018, David has reported no open-market purchases and 5 sales worth $2.2M on SEC Form 4. In the last 12 months: 1 sale ($600K).
1 sale (27% 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 (16 filings), shares returned to the company (2 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 ONTO insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
