Wd-40 Company
A maker of the blue-and-yellow aerosol that fixes squeaky hinges, loosens rusted bolts, and displaces water from electronics—the familiar can found in workshops and garages the world over. The WD-40 Company began in 1953 as the Rocket Chemical Company in San Diego, when chemist Norm Larsen spent forty tries perfecting a rust-preventing solvent for the aerospace trade, notably shielding the Atlas missile from corrosion. The name says it all: WD-40 stands for "Water Displacement, 40th formula," the lucky attempt that finally worked.

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 the last 5 years: -1.7K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
