About
Spencer Brook Asset Management serves high‑net‑worth individuals and trusts, offering discretionary portfolio management and financial planning in a fee‑only arrangement. The firm manages separate accounts composed largely of individual equities and, to a lesser extent, mutual funds, with client assets custodied at TD Ameritrade Institutional.
SBAM follows a bottoms‑up value investing process and typically implements an Equity Income strategy that emphasizes long‑term capital appreciation with supplemental income, avoiding short‑term market trends. Portfolios are managed on a discretionary basis and tailored to client objectives, with an emphasis on limiting downside risk and a multi‑year investment horizon.
Notably, the firm does not serve non‑high‑net‑worth individual clients and maintains a very small client roster, which the brochure indicates supports more individualized oversight. The brochure also highlights active monitoring practices (daily security checks and weekly account reviews), monthly custodian reporting with online access, a formal Code of Ethics and insider trading policy, and the absence of performance‑based fees.

Warmer provides personalized recommendations and introductions to independent fiduciary advisors. We do not supervise advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
Each advisor listed on our site is an independent fiduciary responsible for their own advice. Warmer may receive fees from advisors for participation or referrals; these fees are paid by advisors and do not affect the fees clients pay for advisory services.
For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Please review an advisor's Form ADV and do your own diligence before entering into an advisory relationship.
