A managed portfolio is an investment account where a professional (or an algorithm) makes buy, sell, and rebalancing decisions on your behalf based on your financial goals and risk tolerance. Instead of picking individual stocks or funds yourself, you delegate those choices to someone with the expertise and tools to handle them. Managed portfolios come in several forms, from traditional advisor-run accounts to automated robo-advisor platforms, and they vary widely in cost, control, and complexity.
How a Managed Portfolio Works
When you open a managed portfolio, you typically start by answering questions about your financial goals, time horizon, income, and how much risk you’re comfortable taking. Based on your answers, the manager builds a diversified mix of investments, often spanning stocks, bonds, and sometimes alternative asset classes. From there, the manager handles ongoing decisions: rebalancing when your allocation drifts, reinvesting dividends, and adjusting holdings as market conditions or your personal situation change.
The key distinction from a regular brokerage account is that you’re not placing individual trades. You own the underlying investments, but someone else is steering the ship day to day. This frees you from needing to monitor markets, research individual securities, or time your trades.
Discretionary vs. Non-Discretionary Accounts
Managed portfolios generally fall into two categories based on how much authority the manager has. In a discretionary account, the manager can buy and sell investments without asking your permission for each trade. They operate within guidelines you’ve agreed to (often documented in an investment policy statement), but they don’t need to call you before making a move. This allows faster response times when markets shift or rebalancing opportunities arise.
In a non-discretionary account, the manager recommends trades, but you make the final call on every transaction. You retain more control, and fees tend to be lower because the manager carries less responsibility. The tradeoff is speed: if the manager spots an opportunity or a risk, they have to wait for your approval before acting. Non-discretionary arrangements work well if you want professional guidance but prefer to stay hands-on with decisions.
Types of Managed Portfolios
Robo-Advisor Portfolios
Robo-advisors use algorithms to build and manage a diversified portfolio, usually composed of low-cost index funds or exchange-traded funds. After you complete a risk questionnaire, the platform automatically allocates your money and rebalances it over time. Annual fees typically range from 0.25% to 0.50% of your account balance, which works out to roughly $125 to $250 per year on a $50,000 account. Many robo-advisors have low or no account minimums, making them accessible entry points for newer investors.
Human-Managed Accounts
A traditional financial advisor builds and manages your portfolio personally, often with a broader view of your financial life (retirement planning, estate considerations, tax strategy). The median fee is about 1% of assets managed per year, though some advisors charge as low as 0.30%. On a $500,000 portfolio, a 1% fee means you’re paying around $5,000 annually. In exchange, you get personalized attention, the ability to ask questions, and a manager who can factor in nuances that an algorithm might miss.
Separately Managed Accounts
A separately managed account, or SMA, is a portfolio where you directly own the individual securities rather than shares in a pooled fund like a mutual fund. This structure gives you and your manager more flexibility, particularly around taxes. The manager can sell specific losing positions to offset gains elsewhere in your portfolio, a strategy called tax-loss harvesting. With a mutual fund, you have no control over when the fund manager sells holdings inside the fund, which means you can get hit with taxable capital gains distributions even if you didn’t sell anything yourself. SMAs eliminate that problem because every security sits in your name, and trades can be timed to your personal tax situation.
What You Pay Beyond Management Fees
The management fee (often called an AUM fee, short for “assets under management”) is only one layer of cost. The investments inside your portfolio carry their own expenses. If your manager uses mutual funds or ETFs, those funds charge an expense ratio, typically ranging from 0.03% for a basic index fund to over 1% for actively managed specialty funds. Trading commissions have largely disappeared at major brokerages, but some managed accounts still charge transaction fees for certain types of trades.
When comparing managed portfolio options, add the management fee and the underlying fund expenses together to get the true annual cost. A robo-advisor charging 0.25% that uses index funds with 0.05% expense ratios costs you about 0.30% total. A human advisor charging 1% who uses actively managed funds at 0.75% costs you 1.75% total. Over decades of compounding, that difference can amount to tens of thousands of dollars.
Tax Benefits of Professional Management
One of the most concrete advantages of a managed portfolio is tax-loss harvesting. When an investment in your portfolio drops below what you paid for it, the manager can sell it to “harvest” that loss. The loss offsets capital gains elsewhere in your portfolio (or up to $3,000 of ordinary income per year if you have no gains to offset), reducing your tax bill. The manager then reinvests the proceeds in a similar, but not identical, holding to maintain your portfolio’s target allocation.
Doing this manually is tedious and easy to get wrong, especially because IRS wash-sale rules prohibit you from buying a “substantially identical” security within 30 days of selling at a loss. Automated platforms handle this continuously, scanning for harvesting opportunities across every holding and every purchase lot in your account. Vanguard, for example, notes that automated tax-loss harvesting can check for opportunities across dozens of investments and hundreds of individual lots without missing a day.
Who Benefits Most From a Managed Portfolio
Managed portfolios make the most sense if you fall into one of a few camps. If you don’t have the time, interest, or confidence to manage your own investments, even a low-cost robo-advisor can keep your money properly allocated and rebalanced for less than you might spend on a single bad trade. If your financial situation is complex, involving multiple income sources, stock options, real estate, or estate planning needs, a human-managed portfolio lets you coordinate investment decisions with your broader financial picture.
If you have a large taxable account, the tax-loss harvesting and gain-management strategies available in a managed portfolio (especially an SMA) can generate savings that partially or fully offset the management fee. For smaller, simpler portfolios held entirely in tax-advantaged retirement accounts, a target-date fund or a basic three-fund portfolio you manage yourself can accomplish much of the same thing at a fraction of the cost.
What to Look For When Choosing One
Start with fee transparency. Ask for the total cost, including management fees, fund expenses, and any transaction charges. Next, understand the level of control: will the manager act on your behalf (discretionary), or will they consult you before every trade (non-discretionary)? Check account minimums, which can range from $0 at some robo-advisors to $250,000 or more at traditional advisory firms.
Look at how the manager handles rebalancing and tax management. Some platforms rebalance on a fixed schedule (quarterly or annually), while others rebalance whenever your allocation drifts beyond a set threshold. Threshold-based rebalancing tends to be more tax-efficient because it avoids unnecessary trades. Finally, confirm whether the manager operates as a fiduciary, meaning they are legally required to act in your best interest rather than simply recommending “suitable” investments.
