Stembrook Asset Management, LLC

Stembrook Asset Management is an SEC-registered investment adviser that serves individuals (including high‑net‑worth clients), trusts, estates, charitable organizations, and business entities. The firm provides discretionary portfolio management, selection of third‑party advisers, and modular financial planning and consulting, managing roughly $147.5 million for about 36 clients.

The firm’s investment process draws on fundamental, technical, and cyclical analysis and can incorporate both long‑ and short‑term trades, option transactions, and the use of sub‑advisers or third‑party managers, with continuous supervision and rebalancing under discretionary authority. Stembrook discloses that it may employ derivatives—specifically options and related instruments—within separately managed accounts and may advise on or invest in digital assets, each of which involves specialized risk and custody considerations.

Distinctive operational features include the firm’s use of third‑party platforms to directly manage held‑away retirement and education accounts and its policy of instructing custodians to forward proxy materials to clients rather than voting proxies on their behalf. Stembrook also emphasizes manager selection (TPAs/sub‑advisers) as part of its solutions and discloses receipt of research and technology services from its recommended custodian as part of its brokerage arrangements.
