What Is a Separately Managed Account?
A separately managed account (SMA) is an investment portfolio owned by one investor and managed by a professional investment manager according to a defined strategy. Unlike a mutual fund or ETF, an SMA is not a pooled fund share. The investor directly owns the underlying securities in the account.
That direct ownership is the key distinction. An SMA can offer customization, tax management, and transparency, but it can also require larger account minimums, manager oversight, and a clear understanding of fees and trading authority.
Key Takeaways
- An SMA is a professionally managed portfolio held in an individual investor's account.
- The investor typically owns the underlying stocks, bonds, or other securities directly.
- SMAs can be customized around taxes, restrictions, concentration, or values-based exclusions.
- Fees, minimums, trading practices, and manager discretion vary by program.
- An SMA is not automatically better than a mutual fund or ETF; the value depends on the investor's needs and implementation.
How an SMA Works
An investor opens or uses an account at a custodian or brokerage platform. A manager or advisory program then manages the account under an investment mandate. The mandate may be a large-cap equity strategy, municipal bond ladder, core fixed income portfolio, direct indexing strategy, or another model.
The manager generally has discretion to buy and sell securities within the agreed strategy. The investor receives account-level holdings, transactions, tax lots, and performance reporting. In many programs, the financial adviser helps select the manager and monitors fit.
SMA Versus Mutual Fund or ETF
Feature | SMA | Mutual Fund or ETF |
|---|---|---|
Ownership | Investor owns account securities directly. | Investor owns fund shares. |
Customization | Often can restrict securities or tailor tax handling. | Usually limited to the fund's stated strategy. |
Tax lots | Account-specific lots may support tax-loss harvesting. | Fund-level activity affects taxable distributions. |
Minimums | Often higher. | Often lower. |
Transparency | Holdings are visible at account level. | Holdings disclosure follows fund reporting schedules. |
Where SMAs Can Help
SMAs are most useful when individual ownership changes the result. A taxable investor may value tax-loss harvesting or gain-management flexibility. A concentrated executive may need to avoid adding more exposure to the employer's stock. A municipal bond investor may want a state-specific bond portfolio. A values-based investor may want to exclude certain holdings without buying a separate fund.
They can also help with transition management. If an investor already owns securities with large embedded gains, an SMA may be able to build around those positions instead of forcing an immediate sale.
What to Review Before Using One
Investors should review the advisory fee, manager fee, platform fee, trading costs, account minimum, strategy benchmark, discretion level, restrictions policy, tax-management process, and reporting. The stated strategy matters, but so does the program wrapper around it.
Customization can also create tracking difference. A portfolio that excludes securities, harvests losses aggressively, or works around legacy positions may not match the model strategy exactly. That can be acceptable, but it should be intentional.
Investors should also ask who is responsible for suitability, trading, proxy voting, tax coordination, and ongoing monitoring. An SMA can involve several parties: the investor, adviser, manager, custodian, overlay provider, and platform sponsor. Clear roles help prevent the account from feeling transparent in holdings but opaque in accountability.
Performance reporting should be read carefully as well. An SMA may be compared with a model benchmark, a blended benchmark, or a composite of similar accounts. Because each investor can impose restrictions or enter the strategy at a different time, individual results may differ from the manager's advertised composite. That difference is not automatically a problem, but it should be explained.
The Bottom Line
A separately managed account is a professionally managed portfolio owned directly by one investor. It can be valuable when customization, tax control, and transparency matter enough to justify the added complexity and cost.
