An Investment Manager (also commonly known as an Asset Manager or Portfolio Manager) is a professional person or firm that makes investment decisions on behalf of clients. Think of them as the captain of your financial ship, hired to navigate the often-choppy seas of the market. Their primary job is to grow a client's Investment Portfolio by buying and selling various securities—like stocks and bonds—according to a specific strategy. They handle all the heavy lifting: the research, the analysis, the trading, and the continuous monitoring. In most jurisdictions, like the US and EU, they operate under a fiduciary duty, a legal obligation to act in their client's best financial interest. This means they must put your needs before their own, a crucial principle that, in theory, protects you from conflicts of interest.
Beyond just buying and selling, a good investment manager's life is a whirlwind of activity. They spend their days devouring financial reports, analyzing industry trends, and building complex models to value businesses. Their goal is to find assets that are undervalued by the broader market and avoid those that are overhyped and overpriced. A day in their life might involve:
They are essentially professional business analysts who use capital as their tool.
Investment managers aren't a one-size-fits-all service. They cater to different types of clients with vastly different needs and capital.
Most ordinary investors interact with investment managers indirectly. When you buy shares in a Mutual Fund or an actively managed Exchange-Traded Fund (ETF), there's a manager (or a team) behind the curtain making the decisions. For wealthier individuals, private wealth managers offer a more personalized, hands-on service. A modern, tech-driven alternative is the Robo-Advisor, which uses algorithms to manage a portfolio, offering a lower-cost approach to asset management.
These are the heavyweights. They manage colossal pools of money for entities like Pension Funds (managing retirement savings for millions), university endowments, insurance companies, and sovereign wealth funds. The strategies can be far more complex, but the fundamental job of growing capital remains the same.
This is where you need to pay close attention. An investment manager's fees can significantly eat into your returns over time. Fees are typically structured in a few ways:
High fees create a high hurdle. If a manager charges 2% a year, they need to generate a return of more than 2% just for you to break even. As a value investor, keeping costs low is paramount.
For most people, the honest answer is probably no. The legendary investor Warren Buffett has long advised that the average person is better off not trying to pick a star manager, but instead investing in a simple, low-cost Index Fund. Why? Because decades of data show that the majority of active investment managers fail to outperform their benchmark index after their fees are taken into account. You often pay more for less performance. However, a truly exceptional manager—one with a rational, repeatable process and a long-term mindset—can be worth their weight in gold. The problem is, they are incredibly hard to find, and past performance is no guarantee of future results. The challenge isn't just finding a winner; it's finding one before everyone else does.
If you do decide to seek an active manager, you must do your homework with the critical eye of a value investor like Benjamin Graham. Don't be dazzled by slick marketing; look for substance.
