# Separately Managed Accounts: The HNW Investor's Guide Published: 2026-04-19 Author: Warren Team URL: https://www.heywarren.com/blog/separately-managed-accounts --- When you own a mutual fund, you own a slice of someone else's portfolio. With a separately managed account, you actually own the underlying securities, your own basket of stocks, customized to your tax situation, values, and goals. That ownership distinction unlocks tax-loss harvesting opportunities and customization that pooled funds simply cannot match. For decades, separately managed accounts were the quiet workhorse of high-net-worth wealth management. Family offices, foundations, and ultra-affluent investors used them to gain institutional-quality portfolio management with bespoke tax treatment. Today, thanks to fractional shares, automation, and direct indexing, the SMA structure is reaching investors with as little as $100,000 in taxable assets. The shift matters. An SMA can quietly add 1% to 2% per year in after-tax return through systematic tax-loss harvesting, a benefit that compounds aggressively over decades. Combined with values-based screening, sector exclusions, and concentrated-stock management, separately managed accounts deliver something most fund investors will never experience: a portfolio designed around them rather than the average shareholder. This guide walks through how SMAs work, how they differ from mutual funds and ETFs, what tax advantages they unlock, and how to evaluate managers like Aperio, Parametric, Schwab, and Vanguard. By the end, you will know whether an SMA belongs in your wealth plan, and how to choose one if it does. ## What Are Separately Managed Accounts? Separately managed accounts are individual portfolios of securities owned directly by the investor and managed by a third-party portfolio manager under discretionary authority. Unlike a mutual fund, where you own shares of a pooled vehicle, an SMA puts the underlying stocks and bonds in your name at your custodian. That direct ownership is the defining feature. The manager makes buy and sell decisions on your behalf, but every position sits in your account. You receive cost-basis data on every lot, you control the tax consequences, and you can instruct the manager to exclude specific stocks or industries. ### The legal structure Each SMA operates under an [investment policy statement](/blog/investment-policy-statement), or IPS, that defines the strategy, benchmark, risk tolerance, and any client-specific restrictions. The manager exercises discretionary management within that mandate, while assets remain custodied at a brokerage like Schwab, Fidelity, or BNY Mellon. ### Who uses SMAs Historically, separately managed accounts served high-net-worth families and institutions. Today, lower minimums and direct indexing have opened the structure to mass-affluent investors. Anyone with a meaningful taxable account and a desire for customization is now a candidate. ## Separately Managed Accounts vs Mutual Funds and ETFs The core difference between an SMA and a fund is ownership. In a mutual fund or ETF, you hold shares of a pooled vehicle, and the fund holds the securities. In an SMA, you hold the securities directly. That distinction drives every other meaningful difference in tax control, customization, and reporting. ![SMAs occupy the high-customization, high-tax-control quadrant that funds and ETFs cannot reach.](data:image/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%20720%20480%22%20width%3D%22720%22%20height%3D%22480%22%20role%3D%22img%22%3E%3Ctitle%3EQuadrant%20matrix%3C%2Ftitle%3E%3Crect%20width%3D%22100%25%22%20height%3D%22100%25%22%20fill%3D%22%23f8fafc%22%2F%3E%3Crect%20x%3D%2290%22%20y%3D%2225%22%20width%3D%22300%22%20height%3D%22190%22%20fill%3D%22%23dbeafe%22%2F%3E%3Crect%20x%3D%22390%22%20y%3D%2225%22%20width%3D%22300%22%20height%3D%22190%22%20fill%3D%22%23d1fae5%22%2F%3E%3Crect%20x%3D%2290%22%20y%3D%22215%22%20width%3D%22300%22%20height%3D%22190%22%20fill%3D%22%23ffedd5%22%2F%3E%3Crect%20x%3D%22390%22%20y%3D%22215%22%20width%3D%22300%22%20height%3D%22190%22%20fill%3D%22%23ede9fe%22%2F%3E%3Cline%20x1%3D%2290%22%20y1%3D%22215%22%20x2%3D%22690%22%20y2%3D%22215%22%20stroke%3D%22%2364748b%22%20stroke-width%3D%222%22%2F%3E%3Cline%20x1%3D%22390%22%20y1%3D%2225%22%20x2%3D%22390%22%20y2%3D%22405%22%20stroke%3D%22%2364748b%22%20stroke-width%3D%222%22%2F%3E%3Ctext%20x%3D%22240%22%20y%3D%22108%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2213%22%20font-weight%3D%22700%22%20fill%3D%22%230f172a%22%3ENiche%3C%2Ftext%3E%3Ctext%20x%3D%22240%22%20y%3D%22128%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2210%22%20fill%3D%22%2364748b%22%3E%E2%80%A2%20Active%20fund%3C%2Ftext%3E%3Ctext%20x%3D%22540%22%20y%3D%22100%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2213%22%20font-weight%3D%22700%22%20fill%3D%22%230f172a%22%3ESMA%20Zone%3C%2Ftext%3E%3Ctext%20x%3D%22540%22%20y%3D%22120%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2210%22%20fill%3D%22%2364748b%22%3E%E2%80%A2%20Direct%20Index%20SMA%3C%2Ftext%3E%3Ctext%20x%3D%22540%22%20y%3D%22136%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2210%22%20fill%3D%22%2364748b%22%3E%E2%80%A2%20Active%20SMA%3C%2Ftext%3E%3Ctext%20x%3D%22240%22%20y%3D%22298%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2213%22%20font-weight%3D%22700%22%20fill%3D%22%230f172a%22%3EPooled%20Funds%3C%2Ftext%3E%3Ctext%20x%3D%22240%22%20y%3D%22318%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2210%22%20fill%3D%22%2364748b%22%3E%E2%80%A2%20Mutual%20Fund%3C%2Ftext%3E%3Ctext%20x%3D%22540%22%20y%3D%22298%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2213%22%20font-weight%3D%22700%22%20fill%3D%22%230f172a%22%3EPassive%3C%2Ftext%3E%3Ctext%20x%3D%22540%22%20y%3D%22318%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2210%22%20fill%3D%22%2364748b%22%3E%E2%80%A2%20ETF%3C%2Ftext%3E%3Ctext%20x%3D%2290%22%20y%3D%22425%22%20text-anchor%3D%22start%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2211%22%20fill%3D%22%2364748b%22%3ELow%20Tax%20Control%3C%2Ftext%3E%3Ctext%20x%3D%22690%22%20y%3D%22425%22%20text-anchor%3D%22end%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2211%22%20fill%3D%22%2364748b%22%3EHigh%20Tax%20Control%3C%2Ftext%3E%3Ctext%20x%3D%22390%22%20y%3D%22453%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2212%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%3ETax%20Control%3C%2Ftext%3E%3Ctext%20x%3D%2280%22%20y%3D%2237%22%20text-anchor%3D%22end%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2211%22%20fill%3D%22%2364748b%22%3EHigh%20Customization%3C%2Ftext%3E%3Ctext%20x%3D%2280%22%20y%3D%22405%22%20text-anchor%3D%22end%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2211%22%20fill%3D%22%2364748b%22%3ELow%20Customization%3C%2Ftext%3E%3Ctext%20x%3D%2235%22%20y%3D%22215%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2212%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%20transform%3D%22rotate%28-90%2035%20215%29%22%3ECustomization%3C%2Ftext%3E%3C%2Fsvg%3E) *SMAs occupy the high-customization, high-tax-control quadrant that funds and ETFs cannot reach.* Mutual funds distribute capital gains to all shareholders, even those who recently bought in. ETFs use in-kind redemption to minimize that issue, but they still cannot give you individual-lot tax control. Only separately managed accounts let you harvest losses on specific stocks while maintaining your target index exposure. Customization is equally one-sided. A fund manager cannot remove a stock because you happen to work there or oppose its industry. An SMA manager can, your IPS governs the rules. Minimums and fees flip the comparison: funds win on accessibility and cost, while SMAs win on personalization and after-tax performance. | Feature | Mutual Fund | ETF | SMA | |---|---|---|---| | Ownership | Fund shares | Fund shares | Direct securities | | Tax control | Low | Medium | High | | Customization | None | None | Extensive | | Minimum | $1K-$3K | One share | $100K-$1M+ | | Fees | 0.05-1% | 0.03-0.75% | 0.25-1% | ## How a Separately Managed Account Is Structured An SMA pairs a discretionary portfolio manager with an independent custodian and a written investment policy statement.

You always see every holding, every trade, and every cost basis lot. Transparency is built into the architecture. ### Discretionary management and the IPS The investment policy statement is the contract between you and your manager. It spells out the benchmark, asset allocation targets, tax preferences, restricted securities, ESG screens, and rebalancing rules. The manager exercises discretion within those guardrails, no permission needed for individual trades. ### Custody and reporting Assets sit at a separate custodian, typically a major brokerage. You receive monthly statements showing every position, lot-level cost basis, realized and unrealized gains, and after-tax performance. This level of transparency is impossible inside a pooled fund. ## Direct Indexing: The Modern SMA Revolution Direct indexing is the fastest-growing category of separately managed accounts. Instead of buying an index ETF, the SMA manager buys most of the stocks in the index directly, replicating its return while preserving the ability to tax-loss harvest individual positions. The math is compelling. Even in flat or rising markets, individual stocks experience volatility, some go down while the index goes up. A direct-indexing SMA harvests those losers, banks the tax loss, and replaces them with similar exposure. Over a decade, the cumulative tax alpha can exceed 1% per year. Major providers include Schwab Personalized Indexing, Fidelity Managed FidFolios, Vanguard Personalized Indexing, Goldman Sachs (which acquired Folio), Aperio, and Parametric. Minimums have fallen sharply, with several platforms now accepting accounts at $100,000 to $250,000. ### Why direct indexing took off Three forces converged. Fractional-share trading made it economical to buy 200+ stocks in a small account. Automation reduced the cost of running personalized portfolios. And taxable investors woke up to the after-tax advantage that pooled funds cannot deliver. ### Who benefits most Investors in high tax brackets with sizable taxable accounts. The greater your marginal rate and the longer your time horizon, the more direct indexing earns its fee. ## Tax Benefits of Separately Managed Accounts Tax-loss harvesting is the killer feature of separately managed accounts. By selling individual losers and buying similar replacements, the SMA generates capital losses you can use to offset gains elsewhere, without meaningfully changing your portfolio's market exposure. In a mutual fund, that surgical move is impossible. The fund either holds the stock or it doesn't, and you cannot harvest the embedded loss until you sell the entire fund. An SMA inverts that limitation. Every individual lot becomes a potential tax asset. Beyond loss harvesting, SMAs let you manage gains carefully. You can defer realizations, gift appreciated lots to charity, or transition a concentrated stock position over multiple years to spread the tax bill. The manager works within your specific tax situation rather than the fund's average shareholder. A well-run direct-indexing SMA typically delivers 1% to 2% in annual tax alpha for high-bracket investors during the first several years, tapering as the available losses are exhausted. That tax alpha is real money, the equivalent of an extra 100 to 200 [basis points](/blog/basis-points) of pre-tax return without taking additional risk. ## Customization: Building a Portfolio Around You Customization is the second pillar of the SMA value proposition. Because you own the individual securities, the manager can screen, exclude, or weight positions to match your specific values, holdings, and circumstances. Pooled funds offer no such flexibility. The most common customizations involve ESG screens, excluding fossil fuels, weapons manufacturers, tobacco, or private prisons. Religious investors apply faith-based filters. Executives often exclude their employer's stock or related sector exposure to avoid concentration. ### Concentrated stock management If you hold a large position in a single company, common for founders, executives, or long-term employees, an SMA can be designed to complement that holding by underweighting the same sector and overweighting offsetting exposures. This produces a more diversified total portfolio without forcing you to sell the concentrated position. ### Tax overlays and transition management A tax overlay manages the timing and lot selection of trades to minimize realized gains. Transition management gradually shifts a legacy portfolio into a target strategy over multiple tax years. Both services are routine in the SMA world and largely unavailable in mutual funds. ## SMA Fees and Minimum Investments Fees for separately managed accounts typically run 0.25% to 1% annually, depending on strategy and complexity. Direct-indexing SMAs sit at the low end, around 0.25% to 0.40%. Active [equity](/blog/equity-meaning-in-business) SMAs charge 0.50% to 1%. Bond and specialty strategies vary widely.

A decade ago, $250,000 to $1 million was standard. Today, several direct-indexing platforms accept $100,000, and a few mass-market offerings start lower. Institutional and active equity SMAs still typically require $500,000 to $1 million per strategy. When evaluating cost, focus on the all-in number. Some platforms bundle the SMA fee with a separate advisor wrap fee, which can push the total to 1.5% or more. That stacked structure rarely justifies itself unless the advisor adds substantial planning value beyond portfolio management. ## Use Cases Where SMAs Shine Separately managed accounts are not for everyone. They earn their keep in taxable accounts where customization and tax management produce measurable value. Inside a 401(k) or IRA, the tax-loss harvesting advantage disappears, and a low-cost index fund usually wins. The strongest use cases include high-net-worth families with substantial taxable wealth, executives holding concentrated employer stock, charitable donors who want to gift appreciated lots, ESG-focused investors, and recent liquidity-event recipients transitioning a portfolio over several tax years. In each scenario, the SMA's individual-security ownership unlocks something a fund cannot deliver. ## Top SMA Platforms and Providers The SMA industry consolidated significantly in recent years. The largest dedicated managers include Parametric (owned by Morgan Stanley), Aperio (acquired by BlackRock), and OBP. The major custodians and asset managers, Schwab, Fidelity, Vanguard, and Goldman Sachs, all offer their own direct-indexing SMAs. Parametric and Aperio dominate the customized-equity SMA market and serve both retail and institutional clients through advisors. Schwab Personalized Indexing and Vanguard Personalized Indexing target the mass-affluent direct-indexing segment with low minimums and competitive fees. Fidelity Managed FidFolios and Goldman's Folio platform compete on the same terrain. Most investors access these managers through a registered investment advisor or wirehouse, not directly. Your advisor selects the SMA manager and strategy, handles the IPS, and oversees performance and customization on your behalf. ## Drawbacks of Separately Managed Accounts SMAs introduce complexity that funds avoid. Your statements show hundreds of individual positions, each with its own cost basis and tax history. Tax preparation requires more careful coordination, and the volume of trade confirmations can feel overwhelming. Performance reporting is also more nuanced. Because SMAs prioritize after-tax outcomes, the pre-tax return often lags the benchmark by a small margin, the trade-off for harvested losses. Investors who fixate on pre-tax performance versus the index sometimes miss the larger after-tax win. Finally, SMAs work best with patient capital. Frequent withdrawals or major rebalancing can disrupt the tax-loss harvesting engine and force gain realizations. The structure rewards investors who let the manager work over multiple years. ## How to Choose an SMA Manager Start with track record and transparency. Ask for after-tax performance versus the benchmark over five and ten years, ideally compared to a passive ETF alternative. Demand clarity on fees, including any wrap or platform layers. Request sample reports so you understand what the monthly experience will look like. Evaluate customization depth. Can the manager handle ESG screens, sector exclusions, concentrated-stock complementing, and tax overlays? How quickly do they implement changes? Will they collaborate with your CPA at year-end? The best managers treat tax efficiency and personalization as core deliverables, not optional add-ons. Finally, confirm operational fit. Where will the assets be custodied? What is the onboarding timeline? How does the manager handle cash inflows and withdrawals? A great strategy poorly executed will not outperform a simple ETF after fees and friction. ## Authoritative Sources For deeper background and primary-source data on this topic, the following authoritative sources are useful starting points: - [SEC, Securities and Exchange Commission](https://www.sec.gov/) - [FINRA](https://www.finra.org/) - [Investor.gov](https://www.investor.gov/) - [SEC EDGAR](https://www.sec.gov/edgar) ## Conclusion Separately managed accounts offer something pooled funds structurally cannot: direct ownership of your portfolio's underlying securities, with the customization and tax control that ownership unlocks. For high-net-worth investors with taxable assets, that distinction often translates into 1% to 2% of additional after-tax return per year, real wealth compounded over decades. Five takeaways to keep in mind: 1. SMAs put securities in your name, not in a fund wrapper, enabling individual-lot tax management. 2. Direct indexing has democratized the structure, with minimums now as low as $100,000. 3. Tax-loss harvesting is the most valuable feature, especially for high-bracket investors with long horizons. 4. Customization through ESG screens, sector exclusions, and concentrated-stock overlays is unmatched by funds. 5. Fees run 0.25% to 1% annually, competitive once you account for the after-tax alpha. The future of personalized investing is here. As fractional shares, automation, and AI-driven tax optimization continue to scale, separately managed accounts will become the default structure for serious taxable wealth, not a luxury reserved for institutions.
