Stonebrook Capital Management
Stonebrook Capital Management was established as an SEC-registered investment adviser, focusing on discretionary portfolio management for high-net-worth individuals and institutional accounts. The firm operates from a single location in the United States, building concentrated portfolios that emphasize fundamental, bottom-up security selection. The firm's strategy centers on long-term capital appreciation through direct equity investments and balanced mandates. Stonebrook selects individual securities rather than allocating to outside funds, constructing portfolios with a limited number of high-conviction positions. The investment approach blends classic value orientation with an awareness of durable competitive advantages. Geographic focus remains predominantly domestic US equities, though the firm retains flexibility for international exposure where valuation presents a compelling case. The team scale and precise asset base remain privately held details. Stonebrook maintains a registration footprint with state securities authorities for notice filing purposes. No disclosed adjacent vehicles, philanthropic foundations, or club affiliations appear in public records. Stonebrook's structural position is that of a lean, owner-operated RIA — the portfolio managers acting as principals own the firm and directly manage client capital. This structure aligns investment decisions with client outcomes, as senior decision-makers bear both portfolio risk and fiduciary responsibility without the distractions of distribution-led asset gathering or product manufacturing.

Frequently asked questions
How is Stonebrook Capital Management regulated?
The firm is registered as an investment adviser with the U.S. Securities and Exchange Commission, as documented in SEC public filings. This registration imposes fiduciary obligations, compliance program requirements, and periodic disclosure updates via Form ADV. State notice filings may also apply depending on the location of its clients and its business presence.
What is Stonebrook Capital Management's investment philosophy?
Based on its stated approach in public regulatory records, the firm employs a fundamental, bottom-up investment process emphasizing long-term capital appreciation. It manages concentrated equity and balanced portfolios, selecting individual securities rather than investing through external fund structures. The philosophy relies on deep company research and a willingness to hold positions through market cycles.
Does Stonebrook Capital Management participate in fund commitments or only direct investments?
Stonebrook focuses on direct investment in individual securities — primarily equities and fixed-income instruments — rather than allocating to external fund commitments. The firm constructs portfolios on a fully discretionary basis, tailoring allocations to each client's investment policy statement without layering fund-of-funds fees.
What client types does Stonebrook Capital Management serve?
The firm serves high-net-worth individuals and institutional investors under discretionary mandates, according to its regulatory disclosures. Client accounts are managed on a separately-managed basis, allowing for customization around tax considerations, income requirements, and specific investment restrictions.
How is Stonebrook Capital Management compensated?
Stonebrook typically charges a fee based on a percentage of assets under management, a common structure for discretionary RIAs. This fee-only model means the firm does not earn commissions or transaction-based compensation from securities trading, removing a potential source of conflict between client interests and brokerage revenue.
