Cohu Inc
A maker of machines and software that test and inspect semiconductor chips before they ship, serving computer, automotive, and consumer-electronics companies. It began in 1947 as Kalbfell Laboratories, founded by Dr. David Kalbfell, and took the Cohu name in 1972 after a name used for its electronics division — a nod to Lamott T. Cohu, whose investment group bought the firm in the 1950s. The company once made television cameras and metal detectors before focusing solely on chip testing.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over all recorded history: -1.95M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
