ETFs Vs. Mutual Funds: What's The Difference?

 | Oct 26, 2022 02:34AM ET

If you’re like many investors saving for retirement or another goal, you’ve heard about portfolio diversification. “Don’t put all your eggs in one basket” is among the most common pieces of wisdom dispensed to investors.

Two typical avenues investors might use for diversification are mutual funds and exchange-traded funds (ETFs). When comparing ETFs and mutual funds, it’s important to note that ETFs and mutual funds are similar in that both represent a professionally managed or index-based “basket” of securities, typically stocks and bonds. Yet, they’re structured differently.

Years ago, the key difference between mutual funds and ETFs seemed simple. Most, though not all, ETFs featured a “passive” management approach, and most, though not all, mutual funds featured an “active” management approach. Since then, things have changed. Today, index-based mutual funds are common, while ETFs have expanded and grown to include some very complex, exotic, and risky products. The expense ratios respective to both instruments may also vary; and the features and functionalities that make either instrument a good match for an individual investor is contingent on the investor’s financial goals, resources, and individual investing preferences.

For investors trying to decide whether mutual funds or ETFs are the right choice, it helps to delve a bit deeper in how they compare and contrast. First, let’s look at the landscape, which has changed dramatically over the last 25 years.

As of fall 2021, Bloomberg reported that there were some 2,500 ETFs compared with around 6,300 mutual funds but noted that from 2020 to August 2021, ETFs took in $1.1 trillion compared with just $24 billion for mutual funds. That said, as of early 2022, there were still a total of $27 trillion in mutual fund assets versus $7.2 trillion in ETFs, according to the Investment Company Institute (ICI).
