About

Sierra Investment Management, LLC is an SEC‑registered adviser that provides discretionary investment management and limited financial planning to individuals (including high‑net‑worth clients), trusts, pension and other institutional clients, and separate account PPVA arrangements. The firm reported $360,899,484 in discretionary assets under management as of December 31, 2025 and commonly delivers services through wrap‑fee accounts custodied at Charles Schwab.

The firm follows a rules‑based, tactical investment process that emphasizes quantitative trend‑following signals and a trailing‑stop sell discipline, implementing allocations primarily through mutual funds, ETFs and cash equivalents across a range of model portfolios (Conservative through Growth) and program series. Sierra’s Investment Management Team reviews target portfolio holdings daily and offers model, customized, and programmatic solutions including management of private placement variable annuity separate accounts and variable annuity sub‑accounts.

The brochure discloses notable affiliate and marketing arrangements: an affiliated adviser manages a suite of Ocean Park mutual funds and Ocean Park ETFs, and certain Sierra Programs (including the Schooner Programs) may allocate partly or exclusively to those affiliated funds, with an affiliated‑fund fee offset and related conflict disclosures and mitigation procedures. The firm also describes past use of a third‑party referral operator, maintained distributor registrations to support marketing of affiliated funds, and the provision of quarterly and on‑request performance reports for clients.
