A maker of high-reliability electronic gear and structural components for commercial and military aircraft, Ducommun supplies cable assemblies, printed circuit board assemblies, and lightning diversion systems for planes flown by airlines and armed forces. Its roots reach back to 1849, when Swiss-trained watchmaker Charles Louis Ducommun walked from Arkansas to Los Angeles on foot with a mule, opened a small watch-repair shop, and built a business that became the oldest continuously operating company in California.
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.
