About

Sun Valley Advisory serves individual and high‑net‑worth clients with portfolio management, investment analysis, retirement planning, and risk‑management reviews. The firm primarily advises on ETFs and individual equities and provides access to third‑party money managers and certain annuity and insurance solutions through affiliated insurance activities.

The firm implements client decisions through model‑based allocations and third‑party managers (including the AssetMark platform); clients and their investment adviser representatives select models or TPMs and Sun Valley monitors performance and has authority to hire or fire TPMs. Sun Valley describes its methods as grounded in fundamental analysis and modern portfolio theory, using both long‑ and short‑term purchase strategies and routine cash management, with tax matters generally treated as secondary unless specifically requested.

Sun Valley is notable in reporting $79,517,644 of non‑discretionary assets and $0 discretionary AUM as of March 2026, a structure that is uncommon for team firms and means most account activity is driven by client or TPM authorization rather than firm discretion. The firm is affiliated with Sun Valley Wealth Management and discloses that advisors are licensed insurance agents who may receive commissions on insurance and RILA products and may offer a Wealth.com estate‑planning platform, arrangements the brochure acknowledges and addresses as potential conflicts of interest.
