Diodes Inc /del/
A maker of the tiny semiconductor parts—diodes, transistors, and rectifiers—that sit inside everything from cars and factory machines to AI-server computers. Born in California in 1959, the company took its name from the diode, a two-electrode component whose "di" means two and "ode" means electrode. Long a small regional trader, it grew into a global manufacturer after a Taiwanese maker took a stake in 1990.

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: -7.50M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
