Central Securities Corporation
A closed-end investment company that manages a concentrated portfolio of U.S. equities, seeking long-term growth of capital for its shareholders.

Among its long-running private holdings is Plymouth Rock Company, an auto insurer, a stake that analysts who follow the fund frequently point to.

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: +10.2K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
