Separately Managed Accounts: 7 Things HNW Investors Must Know

If you’ve accumulated $1 million or more in investable assets, you’ve likely noticed that the standard mutual fund and ETF model starts to feel like a poor fit. Separately managed accounts — often called SMAs — offer a fundamentally different structure, one built specifically for investors who need direct ownership, tax precision, and the ability to customize their portfolio in ways a pooled fund simply cannot accommodate.

This guide explains how separately managed accounts work, what they typically cost, and how to determine whether they belong in your overall wealth strategy. We’ll also walk through the specific advantages that matter most to executives, business owners, and retirees managing significant wealth.

What Are Separately Managed Accounts?

The Core Structure of a Separately Managed Account

A separately managed account is a professionally managed investment portfolio in which you — the investor — directly own every individual security. Unlike a mutual fund or ETF, where thousands of investors share ownership of a pool of assets, an SMA holds securities registered in your name in your own custodial account.

When a portfolio manager buys 50 stocks on your behalf inside an SMA, those 50 stocks appear on your brokerage statement with your name attached. You are the beneficial owner of every position. This structural difference has significant tax and planning implications that we’ll explore throughout this article.

How Separately Managed Accounts Differ from Mutual Funds and ETFs

The distinction matters more than most investors realize. Here’s a side-by-side comparison:

Feature	Separately Managed Account	Mutual Fund / ETF
Security Ownership	Direct — registered in your name	Indirect — fund owns the securities
Tax-Loss Harvesting	Full control at the individual security level	Limited or unavailable to the investor
Embedded Capital Gains	None — you control your own cost basis	You may inherit gains from other investors’ activity
Customization	Can exclude specific holdings (e.g., concentrated stock)	No individual security customization
Transparency	Full daily visibility into every position	Quarterly or semi-annual holdings disclosure
Minimum Investment	Higher; set by each manager and strategy	Typically low

This table illustrates why separately managed accounts are designed for affluent investors. The minimum thresholds alone limit access, but the real value is unlocked only when the portfolio is large enough to make individual security management cost-effective.

The Tax Advantages That Matter Most to High-Net-Worth Investors

Tax-Loss Harvesting at the Individual Security Level

This is one of the most compelling reasons wealthy investors turn to separately managed accounts. When you own individual securities, your advisor can selectively sell positions that have declined in value to realize a capital loss, which can then be used to offset capital gains elsewhere in your portfolio.

With a mutual fund, you cannot harvest losses on individual holdings inside the fund — you can only sell or hold your fund shares as a unit. An SMA eliminates that constraint entirely. A portfolio manager running an SMA can harvest losses in specific sectors or positions while maintaining your overall market exposure through replacement securities.

For investors with $2 million or more in taxable accounts, systematic tax-loss harvesting within an SMA can be a meaningful component of long-term wealth building — not by changing what you earn, but by improving what you keep. Consult a qualified tax professional to understand how this applies to your situation.

No Embedded Capital Gains from Other Investors

This is a problem that surprises many first-time mutual fund investors. When you buy shares of a mutual fund, you may be buying into a portfolio that already contains significant unrealized gains from years of prior appreciation. When the fund manager eventually sells those positions — perhaps to meet redemptions from other investors leaving the fund — you receive a capital gains distribution and owe taxes, even if you personally haven’t sold anything.

Separately managed accounts eliminate this entirely. You start with a clean cost basis on every position. No prior investor’s gains are passed through to you. Your tax liability is entirely a function of your own decisions and timing.

Customization to Avoid Concentrated Stock Overlap

Executives and senior employees who hold significant company stock face a particular challenge. If your compensation package has given you $500,000 or more in a single employer’s stock, buying a broad market index fund or ETF that includes that same company adds unintended concentration.

With a separately managed account, you can instruct your manager to exclude specific securities entirely. This “security restriction” feature lets you build broad market exposure while avoiding double-up risk in holdings you already have. It’s a sophisticated planning tool that pooled vehicles simply cannot offer.

Aligning Investments with Values or Business Interests

Some investors have business, legal, or personal reasons to avoid certain industries. An SMA allows for sector-level exclusions — for example, excluding direct competitors, companies under legal review, or industries that conflict with your values. This level of customization is impossible in a mutual fund structure and limited even in ETFs.

What Separately Managed Accounts Cost

Typical SMA Fee Structures

Separately managed accounts are generally priced as a percentage of assets under management. The all-in cost typically reflects two layers: the investment manager’s fee and the advisory or platform fee charged by your wealth manager.

The layers to ask about:

• Investment manager fee: charged by the firm running the strategy; varies by strategy and manager
• Advisor/platform fee: varies by firm and total relationship size
• Trading and custody costs: confirm whether these are bundled or billed separately

Fee structures vary significantly based on the complexity of the strategy, the manager’s reputation, and the size of your account. Larger account balances often qualify for reduced rates. Always ask for a full fee disclosure — including all layers — before committing to any SMA arrangement.

How SMA Costs Compare to Alternatives

The all-in SMA cost is usually higher than a low-cost index ETF’s expense ratio, but that comparison is incomplete for high-net-worth investors. When you factor in the value of direct ownership, tax control, and customization, the relevant comparison isn’t the expense ratio — it’s the after-tax return and the fit with your overall wealth plan.

A mutual fund with a 0.50% expense ratio that passes through an unexpected capital gains distribution in a high-tax year may cost far more than it appears on paper. The tax drag on embedded gains is rarely visible in the fund’s published expense ratio. Consult a qualified financial professional to compare total after-tax costs across structures before making a decision.

Minimum Investment Requirements

Access to separately managed accounts has expanded in recent years, but meaningful minimums remain. Each manager sets its own, and they generally rise with complexity:

• Basic equity SMAs: the lowest minimums, set per strategy
• Multi-strategy or institutional SMAs: materially higher minimums
• Direct indexing SMAs (customized index exposure): minimums have come down as the technology has matured

For investors with $1 million or more in taxable accounts, the SMA structure typically makes practical sense. Below that threshold, the cost of individual security management may outweigh the benefits.

Who Benefits Most from Separately Managed Accounts

High-Net-Worth Investors with Taxable Account Complexity

The more complex your tax situation, the more valuable direct ownership becomes. If you have significant capital gains elsewhere in your portfolio — from a business sale, real estate, or a concentrated stock position — an SMA’s tax-loss harvesting capability becomes a meaningful planning tool.

The ability to realize losses strategically, time gain recognition, and avoid embedded gains from other investors’ activity is most valuable when your marginal tax rate on capital gains is high. For investors in the highest federal tax brackets, that marginal rate on long-term gains can exceed 23% when including the Net Investment Income Tax. Precise tax management in this environment is not a minor consideration — it’s central to wealth preservation.

Executives with Concentrated Stock Positions

Corporate executives, founders, and senior employees often accumulate concentrated positions through equity compensation. Adding broad market exposure through an SMA that excludes the employer’s stock is a practical way to diversify without surrendering index-like exposure or creating additional concentration.

This strategy pairs well with other concentrated stock tools — such as exchange funds, charitable remainder trusts, or a staged selling strategy — as part of a comprehensive approach. Our comprehensive wealth management services include dedicated planning for equity compensation and concentration risk.

Business Owners Approaching a Liquidity Event

If you are preparing to sell a business, the after-tax proceeds will likely represent the most significant single asset you manage. Deploying that capital thoughtfully — with attention to cost basis, gain recognition timing, and portfolio tax efficiency — is a planning priority. Separately managed accounts give you tools that pooled vehicles don’t, starting from day one of the new portfolio.

Retirees Managing Multi-Decade Tax Exposure

Retirees with large taxable portfolios face a long runway of potential capital gains exposure. An SMA structure allows your advisor to manage gain recognition in coordination with Roth conversion strategies, required minimum distributions, and income planning in a way that a mutual fund account simply does not permit.

For example, if you are executing a multi-year Roth conversion ladder, harvesting losses in your taxable SMA in the same year can help offset the income recognized on conversions. This kind of cross-account coordination is only possible when you have direct ownership and full visibility into your positions.

Separately Managed Accounts vs. Direct Indexing: Understanding the Overlap

What Is Direct Indexing?

Direct indexing is a type of separately managed account in which the portfolio manager replicates a broad market index — such as the S&P 500 — by holding the individual constituent securities directly, rather than buying an index fund or ETF. You own each stock individually, which enables all the tax-management and customization features described above.

Direct indexing has grown substantially as technology has reduced trading costs and made it feasible to manage hundreds of individual stock positions efficiently. Morningstar has tracked the expansion of direct indexing as an accessible strategy for affluent investors, particularly those in high tax brackets.

When a Traditional SMA Makes More Sense Than Direct Indexing

Not every separately managed account is a direct index. Traditional SMAs are actively managed — a portfolio manager makes security selection decisions based on a defined investment strategy. Direct indexing is passive in its market exposure, with the active component focused entirely on tax management.

The right choice depends on your goals:

• If your primary goal is tax-managed market exposure, direct indexing SMA structures are often the most efficient path
• If you want active security selection combined with direct ownership, a traditional SMA with an active manager may be appropriate
• Some investors use both — a direct index core for broad market exposure and a traditional SMA for a satellite allocation to a specific strategy

The SEC’s investor bulletin on separately managed accounts provides a useful overview of the structural differences and questions to ask before investing.

What to Look for in an SMA Provider or Advisor

Questions to Ask Before Opening a Separately Managed Account

Not all SMAs are created equal. Before committing to any arrangement, get clear answers to these questions:

1. Who manages the underlying portfolio? Is it an institutional third-party manager, or does your advisor manage it directly?
2. What is the total all-in cost? Request full fee disclosure — manager fee, advisory fee, and any platform or custodial charges.
3. How are tax-loss harvesting decisions made? Is harvesting systematic, discretionary, or triggered by your specific instructions?
4. What customization is available? Can you restrict specific securities, sectors, or ESG criteria?
5. How is performance reported? Ensure you can benchmark the account’s performance net of all fees.

The Role of a Fee-Based Fiduciary Advisor

Working with a fee-based fiduciary advisor matters here. When providing investment-advisory services, a fiduciary is obligated to act in your interest. This is particularly relevant with SMAs, where the fee structure can vary widely and some platforms pay advisors to recommend specific managers.

A fee-based fiduciary advisor discloses all compensation — including any fees received from insurance or annuity products sold separately — so you can evaluate the full picture. At Davies Wealth Management, we believe transparency about costs is foundational to a relationship built on trust. Thomas Davies has been navigating these structures for clients since beginning his financial services career in 1996. The firm has been guiding clients through complex investment decisions since 2009.

If you’re unsure whether your current advisor has a duty to act in your interest, that’s a conversation worth having. You can schedule a discovery conversation to explore whether our approach is a fit for your situation.

Vanguard’s Perspective on Direct Ownership Structures

Vanguard’s research on direct indexing highlights that the after-tax benefit of individually managed stock portfolios is most pronounced for investors in higher tax brackets — precisely the profile of most clients who benefit from SMA structures. Understanding how the strategy performs net of taxes, rather than gross, is essential to evaluating whether an SMA makes sense for your specific situation.

Frequently Asked Questions About Separately Managed Accounts

What is the minimum investment for a separately managed account?

Each manager sets its own minimum, and it depends on the strategy. Direct indexing SMAs have seen minimums come down in recent years due to technology improvements, while more complex or institutional strategies require substantially more to access. Ask for the specific minimum of any strategy you are considering. Your total relationship size with an advisory firm may also affect the minimums available to you.

How do separately managed accounts reduce taxes?

Separately managed accounts reduce taxes primarily through tax-loss harvesting at the individual security level, avoidance of embedded capital gains passed through from other investors, and the ability to time gain recognition based on your personal tax situation. Because you own each security directly, your advisor can coordinate portfolio decisions with your broader tax picture — including Roth conversions, business income, and other capital events. Consult a qualified tax professional to evaluate the specific impact in your situation.

Are separately managed accounts better than ETFs for high-net-worth investors?

For investors with large taxable portfolios, significant capital gains exposure, or concentrated stock, separately managed accounts often provide advantages that ETFs cannot match — particularly in tax management and customization. ETFs remain highly efficient for tax-deferred accounts or for investors without complex tax situations. The right answer depends on your account size, tax bracket, and planning goals, and a qualified advisor can help you evaluate the trade-offs.

What is the difference between a separately managed account and a separately managed account in a unified managed account?

A unified managed account (UMA) is a platform that holds multiple separately managed accounts alongside other investment vehicles — such as ETFs and mutual funds — within a single account structure. A standalone SMA is a single discretionary portfolio with one manager running one strategy. UMAs offer consolidation and rebalancing efficiency across strategies, while standalone SMAs may offer more direct access to a specific manager’s process. Both structures provide the core benefit of individual security ownership.

Do separately managed accounts make sense for retirement accounts?

The tax management benefits of separately managed accounts — particularly tax-loss harvesting — are largely irrelevant inside tax-deferred accounts like IRAs or 401(k)s, since gains and losses inside those accounts don’t affect your current tax bill. SMAs are most powerful in taxable accounts. That said, the customization and transparency benefits of direct ownership can still be valuable in retirement accounts for investors who want security-level control or need to restrict specific holdings. Consult a qualified financial professional to determine the right account type for your SMA allocation.

The Bottom Line on Separately Managed Accounts

For high-net-worth investors managing $1 million or more in taxable accounts, separately managed accounts offer distinct structural advantages — particularly around tax efficiency, transparency, and customization. The ability to own individual securities directly, harvest losses at the position level, avoid embedded gains from other investors, and restrict holdings that conflict with your existing portfolio is simply not available in a mutual fund or standard ETF structure.

The cost of an SMA is real and should be evaluated on a net-of-tax, all-in basis. For the right investor — someone with complexity, concentrated positions, or meaningful capital gains exposure — that cost is often well justified. For investors primarily in tax-deferred accounts or below the practical account minimums, simpler structures may serve better.

The key is evaluating your full picture: your tax situation, existing holdings, income sources, and long-term goals. Separately managed accounts are a tool, not a universal solution — and the value you extract depends heavily on how well the strategy is integrated into your comprehensive wealth plan.
