About
Robert A. Zock & Co., Inc. provides discretionary investment advisory services to individuals, trusts, estates and charitable organizations, and also offers administrative assistance for client non‑U.S. multicurrency securities accounts. The firm typically requires an initial account size (noting a stated $500,000 guideline that may be waived) and delivers portfolio management tailored to each client’s financial circumstances.
The firm follows a long‑term investment philosophy that emphasizes fundamental analysis and long‑term common stock commitments (generally held for more than one year), while avoiding short‑term trading, options, short sales and margin. Portfolios are constructed after a detailed review—often including a personal or family balance sheet—and may include short‑term bonds for reserve positions; investment decisions are generally made on a discretionary basis.
Noteworthy features include the firm’s explicit work with charitable organizations, which is uncommon among independent advisors, and its provision of trusteeship and related administrative services that sometimes result in the firm being deemed to have custody under SEC rules despite third‑party custodians holding client assets. Established in 1976, the firm manages a concentrated book of assets (roughly $155 million across under 100 accounts), reflecting a long‑standing, small‑scale advisory practice.
