Investment management is the professional handling of financial assets on behalf of an individual or institution. It covers everything from deciding how to split money between stocks, bonds, and real estate to picking specific investments, executing trades, and tracking whether the portfolio is actually meeting its goals. You can get investment management through a human advisor, a robo-advisor, or a large firm that manages pooled funds like mutual funds and ETFs.
How the Process Works
Professional investment management follows a structured sequence, though the specifics look different depending on who’s managing the money and how much you have.
It starts with understanding you as an investor. A portfolio manager’s first job is figuring out your financial goals, your tax situation, and your risk tolerance. Someone five years from retirement with most of their wealth in a single company’s stock needs a very different approach than a 30-year-old with decades of earning ahead and a high appetite for volatility. This discovery step shapes every decision that follows.
Next comes portfolio construction, which breaks into three parts. The first is asset allocation: deciding what percentage of your money goes into broad categories like stocks, bonds, and real assets (real estate, commodities, and similar holdings). This also includes whether to invest domestically, internationally, or both. Asset allocation is widely considered the single biggest driver of long-term returns.
The second part is asset selection, where a manager picks specific investments within each category. This is where a manager chooses which stocks fill the equity portion, which bonds fill the fixed-income portion, and which real assets round out the rest. The third part is execution, the actual buying and selling of those investments. Speed matters here, but so do transaction costs, and managers have to balance the two.
The final stage is performance evaluation. Managers measure returns against a benchmark, like the S&P 500 for a U.S. stock portfolio, to see whether their decisions added value. For professional money managers, this is often the most scrutinized part of the job, since underperformance over time is the fastest way to lose clients.
Discretionary vs. Non-Discretionary Accounts
One of the first choices you’ll make when hiring an investment manager is how much authority to hand over. In a discretionary account (sometimes called a managed account), your manager can buy and sell investments without asking your permission first. They still operate within the strategy and guidelines you’ve agreed on, and you can tell them to leave specific holdings alone, but they don’t need to call you before making a trade. This gives them flexibility to act quickly when they spot an opportunity or need to rebalance.
In a non-discretionary account, your manager can research investments and make recommendations, but they cannot execute a single trade without your explicit approval. You and your manager typically develop a strategy together, and then the manager brings you specific trades that fit that strategy. You sign off before anything happens. This arrangement gives you more control but can slow things down, especially if a time-sensitive opportunity comes up and the manager is waiting for you to respond.
Active and Passive Strategies
Investment management generally falls into two broad camps: active and passive.
Active management aims to beat the market. Active managers buy and sell frequently, hold investments for relatively short periods, and look for pricing inefficiencies or short-term opportunities. They might trade individual stocks, options, mutual funds, or ETFs. The trade-off is higher costs, both in management fees and in transaction expenses from frequent trading. Research consistently shows that most active managers fail to outperform their benchmark index over long periods, though some do add meaningful value, particularly in less efficient markets like small-cap stocks or emerging markets.
Passive management takes the opposite approach. Instead of trying to beat the market, passive investors try to match it. The goal is to capture the market’s long-term tendency to rise. Passive strategies rely heavily on index funds and ETFs that track a specific benchmark. Trading is minimal, which keeps costs low. A passive portfolio tracking the total U.S. stock market, for example, simply holds shares in proportion to each company’s market value and only adjusts when the index itself changes.
Many investors end up with a blend. A portfolio might use low-cost index funds for the core of its stock allocation while hiring an active manager for a smaller allocation to international or alternative investments where the manager’s expertise is more likely to justify the higher fees.
What Investment Management Costs
The most common fee structure is a percentage of assets under management (AUM). This means you pay a set percentage of your portfolio’s value each year. The median AUM fee among human advisors is about 1%, though fees can range from 0.25% to 2% depending on the firm and the size of your account. On a $500,000 portfolio at 1%, that’s $5,000 per year.
Robo-advisors, which use algorithms to build and manage portfolios with minimal human involvement, charge significantly less: typically 0.25% to 0.50% annually. On that same $500,000 portfolio, a robo-advisor at 0.30% would cost $1,500 per year.
Larger accounts often benefit from tiered fee schedules. Instead of one flat rate, the advisor charges different rates on different portions of your assets. For example, the first $1.5 million might be charged at 1.00%, the next $1.5 million at 0.80%, and amounts above $5 million at 0.50%. This means the effective rate drops as your portfolio grows.
Some advisors offer alternative pricing. Flat annual retainers typically run $2,500 to $9,200, while hourly fees for specific projects (like analyzing a business sale or planning around a divorce) range from $200 to $400 per hour. These structures are less common for ongoing portfolio management but can make sense if you mainly need planning rather than day-to-day investment oversight.
Keep in mind that AUM fees are separate from the internal costs of the investments themselves. If your manager puts you in mutual funds or ETFs, those funds charge their own expense ratios, which you pay on top of the management fee.
Fiduciary vs. Suitability Standards
Not all investment professionals are held to the same legal standard, and the difference matters for your wallet.
Registered investment advisors (RIAs) are bound by a fiduciary standard under the Investment Advisers Act of 1940. A fiduciary has a duty of loyalty and care, meaning they must put your interests ahead of their own. In practice, this means they can’t buy securities for their own accounts before buying them for you, they must disclose potential conflicts of interest, and they have to seek the best combination of low cost and efficient execution when placing trades. Their advice must be based on thorough, accurate analysis.
Broker-dealers, on the other hand, follow a suitability standard set by FINRA (the Financial Industry Regulatory Authority). Suitability means their recommendations must be appropriate for your financial situation, but they aren’t required to prioritize your interests above their own. A broker might recommend a mutual fund that pays them a higher commission as long as the fund is still a reasonable fit for your needs. Their primary income comes from commissions on transactions, which creates an inherent tension that the suitability standard doesn’t fully eliminate.
When choosing an investment manager, asking whether they act as a fiduciary is one of the most important questions you can raise. The answer tells you whose interests the law requires them to serve.
Who Uses Investment Management
Investment management isn’t just for the wealthy. Robo-advisors have brought professionally managed portfolios to people with as little as a few hundred dollars to invest. Target-date funds inside 401(k) plans are another form of investment management, automatically shifting your asset allocation as you approach retirement.
That said, the value of a dedicated investment manager tends to increase with complexity. If you have a concentrated stock position from an employer, rental properties, stock options, or assets in multiple account types with different tax treatments, a human manager can coordinate across all of those pieces in ways a simple index fund strategy can’t. The same goes for retirees drawing income from several sources, where the sequence of withdrawals can meaningfully affect how long the money lasts.
For straightforward situations, a low-cost robo-advisor or a simple portfolio of index funds may accomplish most of what a full-service manager would do, at a fraction of the cost. The right level of management depends on what you own, what you’re trying to accomplish, and how much of the work you’re willing to do yourself.
