Mutual funds are investments that combine money from many investors to invest toward a common goal.
Mutual funds allow investors to pool their money to invest in a diverse portfolio of stocks, bonds, or other assets. They can be a great way to get exposure to the stock market and other types of asset classes, without the need to research and select individual stocks.

Mutual funds are more hands-off investments than building a portfolio of individual stocks and bonds. That's for sure. However, there's a lot you should know before you invest in your first mutual fund.
With that in mind, here are some things you should consider as you get started. By the time you have read through this article, you will be in a much better position to invest.
1. Active versus passive funds
First, you should understand the difference between an actively managed and a passively managed mutual fund.
An actively managed mutual fund employs managers who select investments for the fund. A passive mutual fund simply tracks a benchmark index, such as the S&P 500.
Let's be clear: The goal of a passively managed mutual fund is to match the performance of a benchmark index. An actively managed mutual fund aims to beat a benchmark. For this reason, passive mutual funds are also known as index funds.
In practice, however, the majority of active mutual funds don't outperform index funds. In any given year, 40% to 50% of actively managed funds beat their benchmarks. There are some excellent active mutual funds, but it's essential to take a close look at a fund's track record before investing.
2. Expense ratio and other costs
Before you invest, you should know how much a mutual fund costs. The main type of fee you should be aware of is the expense ratio, which is the percentage of the fund's assets that goes toward annual fees. For example, a 1% expense ratio means you'll pay $100 in annual investment fees on a $10,000 account.
Passive mutual funds tend to have expense ratios in the 0.03% to 0.25% range. Active mutual funds tend to have higher expense ratios, often in the ballpark of 1%. This is because they have the added expense of paying investment managers.
The other consideration is how much of your portfolio should be in mutual funds. If you want to keep your investments on autopilot, there's absolutely nothing wrong with having a portfolio made up entirely of mutual funds. However, if you want to buy stocks as well, mutual funds can help form a nice core for your portfolio.
5. Open an account
When it comes to actually buying mutual funds, you have two choices. First, you can open an online brokerage account and place your mutual fund orders there.
Alternatively, you can open an account and buy mutual funds directly through the companies that offer them. For example, if you want to invest in a mutual fund offered by T. Rowe Price (TROW -1.43%), you can do so directly through the company.
The brokerage route is a great choice if you want to own mutual funds from several different firms. Plus, there is value in holding a portfolio of mutual funds and stocks in one place. Many top online brokers provide excellent mutual fund screening and research tools.
Alternatively, a direct account with the fund provider can be an excellent way to avoid paying a commission for funds that don't appear on your broker's no-transaction-fee (NTF) list.
6. Keep an eye on your mutual funds after you buy them
Finally, it's worth discussing what you should do after you invest in mutual funds. Specifically, it's important to occasionally assess your portfolio and rebalance if needed. Through the natural course of market movements, you might find that your asset allocation shifts.
For example, if you're targeting an allocation of 60% stocks and 40% bonds with your mutual funds, strong stock market performance could push this to 70% and 30%. To keep your portfolio's risk level appropriate to your situation, it's important to conduct this checkup every year or so.
