The AssetMark Platform: a survey of what's offered through one of the industry's largest TAMPs
A working overview of the investment vehicles, model providers, and proprietary solutions available through AssetMark's wealth management platform — useful context for advisors evaluating outsourced asset management.
What AssetMark is, in plain terms
AssetMark is a turnkey asset management platform (TAMP). It does not work directly with retail clients. Instead, it provides independent financial advisors with a curated menu of investment solutions, plus the back-office plumbing — trading, rebalancing, billing, reporting, and custody — to run those solutions for client households.
Founded in 1996, AssetMark serves more than 10,000 financial advisors and roughly 300,000 investor households, with over $160 billion in platform assets as of December 2025. In 2024 the firm went private under GTCR ownership, and in 2024–2025 it acquired Adhesion Wealth and Morningstar Wealth's TAMP assets, broadening its model and SMA lineup considerably.
For advisors, the relevant question isn't "what does AssetMark do?" — it's "what can I put a client portfolio in?" The sections below answer that.
The seven solution categories
AssetMark organizes its investment lineup into solution types. Each can be used standalone or combined inside a unified managed account (UMA) sleeve structure.
Mutual Fund Strategies
Model portfolios built from open-end mutual funds, allocated by a portfolio strategist. Often the entry point on the platform.
- Third-party strategist models (e.g., American Funds, JP Morgan)
- AssetMark proprietary GuidePath and GuideMark Fund-of-Fund models
- GPS Fund Strategies and GPS Select (AssetMark Investment Strategies Group)
ETF Strategies
Model portfolios constructed primarily from exchange-traded funds. Designed for lower internal expense ratios and tax efficiency.
- Market Blend ETF Strategies (AssetMark proprietary)
- Market Dimensions (factor-tilted ETF allocations)
- Morningstar ETF Models (added 2024)
- Third-party ETF strategist models (BlackRock, State Street, First Trust, others)
Separately Managed Accounts (SMAs)
Direct ownership of individual securities inside a model managed by an institutional manager. Useful for tax-loss harvesting, concentration management, and customization.
- Equity SMAs across U.S. and international, large- through small-cap
- Morningstar Equity SMAs (seven strategies added 2024)
- Fixed-income SMAs (municipal, taxable, ladders)
- Managers include Acadian, Edge, Hartford, Logan, Clark Capital, and many others
Unified Managed Accounts (UMAs)
Multi-sleeve accounts that combine SMAs, mutual funds, ETFs, and now private market funds inside a single custody account, with AssetMark serving as overlay manager.
- Savos UMAs (proprietary, multi-asset)
- Adhesion UMA framework (300+ manager models)
- Tax overlay and rebalancing automation built in
Investment Manager Accounts / Multiple Strategy Accounts
Discretionary accounts where a single institutional manager (or a blend of managers) runs the portfolio. Distinct from model SMAs because the manager has trading discretion.
- Core Markets IMAs across the six risk profiles
- Custom IMAs with client-specified restrictions
- Multiple Strategy Accounts combining managers across asset classes
Guided Income Solutions
AssetMark-proprietary retirement income models built to support specific withdrawal rate ranges while preserving as much of the initial capital base as practical.
- Retirement Income — Conservative (Profile 1)
- Retirement Income — Moderate (Profile 2)
- Retirement Income — Enhanced (Profile 3)
- PIMCO-managed fixed income sleeves available exclusively at AssetMark
Alternative & Private Markets
Two parallel offerings: a curated iCapital-diligenced menu for qualified HNW investors, and integrated semi-liquid private funds available with a $10,000 platform minimum.
- iCapital: private equity, private credit, hedge funds (HNW only)
- Apollo Diversified Credit, Carlyle Tactical Private Credit
- KKR Real Estate Select Trust, StepStone Private Infrastructure Fund
- Goals-based growth, income, and preservation private market portfolios
- GPS Select Access and Savos Personal Portfolios Access ($250K min) blend public and private allocations
Retirement Plan Platform
Not technically an "investment solution" but the wrapper through which many of the above are delivered into qualified plans.
- 401(k), Solo(k), Profit Sharing, Pooled Employer Plans
- 403(b), Cash Balance, traditional pension, non-qualified plans
- Curated model portfolios and mutual fund lineups for plan menus
The proprietary fund families
Several of AssetMark's solution types are built from in-house mutual funds. These are advised by AssetMark itself and typically sub-advised by outside institutional managers.
| Fund Family | Structure | Typical Advisory Range |
|---|---|---|
| GuideMark Funds | No-load, sub-advised mutual funds across equity, fixed income, and tax-managed sleeves | 0.45% – 0.57% |
| GuidePath Funds | No-load funds-of-funds and a sub-advised fund; used as building blocks in GPS Fund Strategies | 0.25% – 1.05% |
| Savos Dynamic Hedging Fund | Tactical hedging strategy used within Savos UMA solutions | ~1.20% |
Fund-level advisory rates per AssetMark's publicly filed disclosures and SmartAsset's review of Form ADV. AssetMark retains only a portion of these fees; sub-advisors are paid from the remainder. All figures subject to change in current Fund Prospectus.
A partial list of third-party portfolio strategists
AssetMark's open-architecture model means most well-known asset managers have at least one strategy on the platform. The following is a representative — not exhaustive — sample drawn from AssetMark and industry sources.
An advisor's read on the lineup
For an independent RIA, AssetMark's value proposition is breadth plus operational outsourcing, not unique alpha. The platform's strength is in giving a small firm institutional-grade access to SMAs, UMAs, and now private markets — alongside trading, rebalancing, and tax overlay infrastructure that would otherwise be cost-prohibitive to build.
Strategists and managers can be added, replaced, or removed at AssetMark's discretion. That is appropriate due diligence on AssetMark's part, but it does mean a client's specific manager or model is not contractually permanent. Advisors should document the original selection rationale and review any platform-driven manager changes.
For concentrated-stock fact patterns common among utility-sector retirees — particularly Southern Company employees holding SO inside a 401(k) or after rollover — the SMA and UMA capabilities are the most operationally relevant, because tax-loss harvesting and customized exclusion lists can be applied directly inside the managed account.
