American Vanguard Corporation
A maker of crop-protection chemicals and specialty products, American Vanguard produces insecticides, herbicides, fungicides, and soil fumigants for farmers, plus products for turf, public health, and animal health. Founded in 1969 in Los Angeles as a regional contract manufacturer of agricultural chemicals, it now operates mainly through its AMVAC Chemical subsidiary. Its name comes from "vanguard"—the foremost part of an advancing force—and its SIMPAS system lets farmers apply several inputs at planting.

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 3 years: +252.2K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
