About Luis A Muller's insider trades
Luis A Muller is President & CEO at Cohu (COHU). Since May 2, 2017, Luis has reported 1 open-market purchase worth $100K and 10 sales worth $14.5M on SEC Form 4. In the last 12 months: 4 sales ($8.8M).
2 sales (23% 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 shares withheld for taxes (46 filings), grants and awards (25 filings), option exercises (5 filings), other transactions (3 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 COHU insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
