Separately Managed Accounts: Direct Ownership Explained

Key Takeaways

• A separately managed account holds actual stocks and bonds in your name, not shares of a pooled fund.
• Equity SMA fees typically run 40 to 100 basis points per year, with minimums from 50,000 to 500,000 dollars.
• The most common mistake is assuming an SMA beats index funds, the case is customization and tax control, not alpha.
• SMAs are most valuable in taxable accounts where direct ownership enables tax-lot harvesting and reduces embedded capital gains.

What It Is

An SMA is a private investment account, not a pooled vehicle. Unlike a mutual fund or ETF, where you own shares of a fund that owns the stocks, an SMA holds the actual stocks and bonds directly under your account number. A registered investment adviser or asset manager is hired to run the portfolio against a defined mandate, for example US large cap growth, municipal bonds in a specific state, or a diversified ESG strategy.

Because you own the underlying securities, you see every name, every cost basis, and every tax lot. That direct ownership is the core feature that separates an SMA from a fund.

The Intuition

Pooled funds are efficient but blunt. Every investor in an S&P 500 mutual fund receives the same allocation, the same embedded gains, and the same year-end capital gains distribution, regardless of their personal tax situation or preferences. SMAs solve that by giving each client their own portfolio that can be tailored. The trade-off is higher minimums and higher fees than a plain ETF.

The structure became popular first among pensions and endowments in the 1970s, then spread to high-net-worth private wealth. Technology and fractional shares have pushed minimums down, making SMAs accessible to mass-affluent investors rather than only institutions.

How It Works

A typical SMA relationship has four parties. The client opens a custody account at a broker-dealer or trust company. The financial advisor recommends a strategy. The asset manager (sometimes called the sub-advisor) executes trades inside the account. The platform sponsor, often a wirehouse or turnkey asset management program, handles billing, reporting, and model delivery.

Fees typically run 40 to 100 basis points per year for equity SMAs, higher for niche strategies. Minimum account sizes range from about 50,000 dollars at the low end to 500,000 dollars or more for specialty mandates. Customization options commonly include:

• Tax-lot selection and harvesting of individual losses
• Screens that exclude specific tickers, industries, or ESG categories
• Transition management from a legacy portfolio to avoid realizing embedded gains
• State-specific bond selection for municipal SMAs

The investment manager delivers a model portfolio, and either the manager or the platform trades the model into each client account. Because the holdings live in the client's name, the client keeps the cost basis that results.

Worked Example

Suppose an investor retires with 500,000 dollars in a taxable account holding a large-cap index ETF with 200,000 dollars of embedded capital gains. Selling the ETF to reallocate would trigger a large tax bill.

Instead, the advisor moves the assets in-kind into an SMA mandated to a similar large-cap strategy. The manager keeps most of the existing positions, gradually sells the lots with the smallest gains, and harvests offsetting losses when individual names dip below cost basis. Over the first two years the client realizes only the losses needed to offset other portfolio gains, while the portfolio tracks the intended benchmark within a tight range. The SMA preserved tax efficiency that a fund swap would have destroyed.

Common Mistakes

1. Assuming an SMA always beats a fund. SMAs cost more than index ETFs and do not, on average, outperform a cheap benchmark. The case for an SMA is customization and tax control, not alpha.

2. Ignoring total cost. The headline management fee is only part of the bill. Platform fees, custody charges, and trading costs can add another 20 to 40 basis points. Compare the all-in wrap fee, not just the manager fee.

3. Over-customizing. Heavy restriction lists, such as excluding thirty tickers and tilting toward five themes, can push tracking error against the stated benchmark into a range that no longer resembles the strategy. If you screen out too much, you are no longer buying the manager's process.

4. Forgetting the wash-sale rule. Tax-loss harvesting in an SMA can be undone if the same security is repurchased in another account, including an IRA or a spouse's account, within thirty days. Coordination across household accounts matters.

5. Chasing performance history. SMA composite returns shown to prospects are typically GIPS-compliant averages across many client accounts. Your specific account, with its own customizations and entry timing, will not match that track record exactly.

Frequently Asked Questions

Q: What is a separately managed account in simple terms? An SMA is a private portfolio of individual stocks and bonds held in your own account, managed by a professional firm to a defined strategy. Unlike a mutual fund, you own the underlying securities directly.

Q: How does a separately managed account affect investment decisions? SMAs let advisors customize holdings for your tax situation, exclude companies you want to avoid, and harvest individual losses. These features can meaningfully improve after-tax returns in taxable accounts, but they cost more than index ETFs.

Q: What is a real-world example of a separately managed account? An investor moves a large-cap ETF with 200,000 dollars of embedded gains into an SMA. The manager holds most existing positions, harvests losses on individual names over two years, and reduces the tax bill the investor would have faced from selling the ETF outright.

Q: How can investors use a separately managed account effectively? SMAs work best in taxable accounts for investors with significant capital gains to manage, concentrated positions to diversify around, or values-based screens. They are rarely justified in tax-advantaged accounts like IRAs where the tax features have no value.

Q: How is a separately managed account different from a mutual fund? In a mutual fund you own shares of the fund, not the underlying securities. Gains and losses inside the fund are invisible to you and distributed on the fund's schedule. An SMA lets you control when gains are realized and which specific lots are sold.
