What Is a Separately Managed Account? You Own the Securities, Not a Slice of a Pool
A separately managed account holds individual securities in your name, run by a manager to a stated strategy. You own the stocks or the bonds directly. You do not own a share of a pooled fund.
A separately managed account holds individual securities in your name, run by a manager to a stated strategy. You own the stocks or the bonds directly. You do not own a share of a pooled fund.
That one difference drives everything else. Tax treatment, customization, transparency, minimum size, and the amount of administrative work behind the scenes all follow from direct ownership.
I run an ETF business and I have run separately managed accounts for advisers for years. What follows is how one actually works, including the parts that rarely make the brochure.
How does a separately managed account work?
You open an account at a custodian. Schwab, Fidelity and Pershing are the common ones. The account is yours. Then you hire a manager and give them trading authority on it.
The manager runs a model. When the model says buy Microsoft, the manager trades it in your account, and in every other account on that model.
Trades are usually placed as one block and allocated across accounts, which keeps execution fair. Your holdings still drift a little from the model, because you funded on a different day at a different price.
Your statement lists the actual shares. Not a fund name.
What is the difference between an SMA and a fund?
A fund pools everyone’s money. You buy a share of the pool. The pool carries one cost basis history and one set of realized gains, and you inherit both on the day you buy in.
An SMA gives you your own copy of the strategy. Your cost basis is yours. Nobody else’s redemption creates a taxable event in your account.
| Pooled fund | Separately managed account | |
|---|---|---|
| What you own | A share of the pool | The securities themselves |
| Tax lots | A shared history you inherited | Your own, starting the day you funded |
| Customization | None | Exclude a stock, a sector, an industry |
| Transparency | Holdings on a lag | Daily, on your own statement |
| Minimum | One share | Commonly $100,000 to $250,000 |
Why does direct ownership matter at tax time?
Because losses inside an index are invisible when you own the index as one line.
An index can be down for the year while a third of its members are up. Own the fund and you see one number. Own the names and you can sell the losers, book the loss, then buy something similar and stay invested.
That is tax-loss harvesting, and it is the main reason advisers move taxable money into an SMA.
A worked example: inside the S&P 500 in 2022
The S&P 500 fell about 18% on a total-return basis in 2022. One line on a statement. One loss.
Underneath, the spread was enormous. Meta finished the year down about 64%. Tesla fell about 65%. Amazon fell about 50%. In the same index over the same twelve months, Exxon Mobil rose about 80% and Chevron rose about 53%.
Own the index fund and you have one lot showing a loss. Hold the 500 names and you have dozens of lots deep in the red, beside winners you never had to touch.
You harvest the losers in March, again in June, and again in October. The strategy stays intact and the losses go on Schedule D.
2022 was unusual in the size of the drop. It was not unusual in its dispersion. Even in a strong year, roughly a third of index members finish lower.
The benefit front-loads
Harvesting needs lots trading below what you paid for them, and those are thickest early, while the account still sits near its funding price. Most of the benefit lands in years one through five.
A ten-year-old account in a market that went up is mostly embedded gain, with very little left to sell at a loss. The fee keeps running either way, which is a calculation worth redoing every few years rather than once at the open.
Why doesn’t everyone run one? Start with the minimum
Two portfolio managers who ran SMAs for decades before launching ETFs put the same number on it, independently, on Behind the Ticker.
Kirk McDonald is a portfolio manager at Argent Capital Management, which ran separately managed accounts for 24 years before it launched a fund. His description of the entry ticket: "when you’re doing separately managed accounts, you need, you know, a hundred thousand dollars to $250,000 at a time". The fund, he said, was how the firm gave people access "for a few dollars at a time".
Jeff Cullen, Managing Director at Schafer Cullen Capital Management, quotes the same figure on a strategy his firm has run in SMA form for 14 years. Because it writes options on the underlying names, "it’s a $250,000 minimum per account". Advisers came to him asking for the strategy in IRAs and in smaller accounts, "because it’s easier to implement and I can get it at a lower minimum".
The minimum is not a gate the manager invented. Below it, an account cannot hold enough positions to track the model, and the tracking error swamps the tax benefit you came for.
The part nobody budgets for: every account is its own account
A fund is one portfolio with one set of books. A hundred SMAs are a hundred portfolios with a hundred sets of books.
Raymond Holst is a tax attorney at Practus LLP who works on the 351 exchanges that move these portfolios into fund structures. Testing one, he cannot look at the strategy in aggregate: "if you’re running separately managed accounts, maybe you have 50 accounts. You have to look at each account individually. It’s not the aggregate portfolio." Each account’s own cost basis and holding periods then have to travel "from the current custodian into the new fund administrator".
Cullen’s firm manages 13 separate SMA strategies and picked one to run as a fund as well. He describes that version as "very, very easy to implement across the board versus the paperwork and everything that goes involved with a separately managed account".
The tax machinery runs in both directions
Direct ownership means your losses are yours. It also means your gains are yours, in your tax year, whenever the manager trades.
Sal Esposito of Zacks Investment Management ran into that directly. Zacks looked at putting its small and mid-cap portfolios into a fund because of what turnover does inside an account: "they have 100% turnover in them. A lot of advisor pushback on 100% turnover in a separately managed account."
Bob Elliott, co-founder and CIO of Unlimited, makes the same point about a strategy that shifts positions often. Inside a fund the investor sees a single holding, "without the investor having to, you know, absorb short term capital gains that could come from, say, a separately managed account".
The pattern across all four practitioners is the same: an SMA suits a strategy that trades lightly and holds appreciated positions. A strategy that turns over hard is a poor fit for a taxable account you own directly.
What does a separately managed account cost?
You pay the manager a fee on assets, billed from the account each quarter. You also pay the custodian, though trading is commission-free at the major ones now.
Compare that against a fund’s all-in cost, not against zero. A fund charges its fee inside the net asset value where you never see it. An SMA charges it on a statement line where you do. Same money, different visibility.
When is a separately managed account the wrong answer?
Often. Here is when it fails.
In a retirement account. The tax machinery is the main reason to pay for an SMA. In an IRA there is nothing to harvest, so you are paying for an idle machine. Esposito, who sold SMAs at UBS before he moved to ETFs, now says he does not see why anybody would use one "unless they were using an index-based tax-managed fund". Read that as a statement about which job the wrapper is for.
When the account is small. Below roughly $100,000 you cannot hold enough names to track the strategy.
When the strategy trades a lot. Harvesting needs losses. A high-turnover strategy in a rising market realizes gains instead, and the bill arrives every year.
After the first several years. The harvest front-loads, and a long-held account in an up market has little left to sell at a loss.
When the wash-sale rule bites. Buy a substantially identical security within 30 days either side of the loss sale and the loss is disallowed. That includes purchases in your IRA and your spouse’s account. Harvesting badly is worse than not harvesting at all.
Where a risk-managed strategy fits
The same strategy can be delivered either way. THOR runs separately managed accounts for advisers and runs the same systematic signal logic inside its funds.
The approach is rules-based and seeks to reduce drawdowns rather than forecast them. The choice of wrapper is a question about the account, not about the strategy. Taxable money with a long horizon and low-basis stock is an SMA question. A retirement account is a fund question. Most advisers run both, because most clients bring both kinds of money.
Definitions

Unified managed account (UMA). One account holding several SMA models plus funds, coordinated by a single overlay manager.
Direct indexing. An SMA that replicates an index by holding its members, usually to harvest losses.
Tax-loss harvesting. Selling a position below cost to realize a loss, then buying a similar security to stay invested.
Wash sale. A disallowed loss, triggered by buying a substantially identical security within 30 days before or after the sale.
Tracking error. How far the account’s result drifts from the model it copies.
Overlay manager. The party that sequences trades across several models in one account so they do not conflict.
