ETFs vs. Mutual Fund: An Overview
Investors face a bewildering array of choices: stocks or bonds, domestic or international, different sectors and industries, value or growth. Deciding whether to buy a mutual fund or exchange-traded fund (ETF) may seem like a trivial consideration next to all the others, but there are key differences between the two types of funds that can affect how much money you make and how you make it.
Both mutual funds and ETFs hold portfolios of stocks and/or bonds and occasionally something more exotic, such as precious metals or commodities. They must adhere to the same regulations covering what they can own, how much can be concentrated in one or a few holdings, how much money they can borrow in relation to the portfolio size, and more.
Beyond those elements, the paths diverge. Some of the differences may seem obscure, but they can make one type of fund or the other a better fit for your needs.
- Both mutual funds and ETFs hold portfolios of stocks and/or bonds and occasionally something more exotic, such as precious metals or commodities.
- Both can track indexes as well, however ETFs tend to be more cost effective and more liquid as they trade on exchanges like shares of stock.
- Mutual funds can provide some benefits such as active management and greater regulatory oversight, but only allow transactions once per day and tend to have higher costs.
Mutual Funds Vs ETFs
As the name suggests, exchange traded funds trade on exchanges, just as common stocks do, and the other side of the trade is some other investor like you, not the fund manager. You can buy and sell at any point during a trading session at whatever the price is at the moment based on market conditions, not just at the end of the day, and there’s no minimum holding period. This is especially relevant in the case of ETFs tracking international assets, where the price of the asset hasn’t yet updated to reflect new information, but the U.S. market’s valuation of it has. As a result, ETFs can reflect the new market reality faster than mutual funds can.
Another key difference is that most ETFs are index-tracking, meaning that they try to match the returns and price movements of an index, such as the S&P 500, by assembling a portfolio that matches the index constituents as closely as possible.
Passive management isn’t the only reason that ETFs are typically cheaper. Index-tracking ETFs have lower expenses than index-tracking mutual funds, and the handful of actively managed ETFs out there are cheaper than actively managed mutual funds.
Clearly, something else is going on. It relates to the mechanics of running the two kinds of funds and the relationships between funds and their shareholders.
In an ETF, because buyers and sellers are doing business with one another, the managers have far less to do. The ETF providers, however, want the price of the ETF (set by trades within the day) to align as closely as possible to the net asset value of the index. To do this, they adjust the supply of shares by creating new shares or redeeming old shares. Price too high? ETF providers will create more supply to bring it back down. All of this can be executed with a computer program, untouched by human hands.
The ETF structure results in more tax efficiency, too. Investors in ETFs and mutual funds are taxed each year based on the gains and losses incurred within the portfolios, but ETFs engage in less internal trading, and less trading creates fewer taxable events (the creation and redemption mechanism of an ETF reduces the need for selling). So unless you invest through a 401(k) or other tax-favored vehicles, your mutual funds will distribute taxable gains to you, even if you simply held the shares. Meanwhile, with an all-ETF portfolio, the tax will generally be an issue only if and when you sell the shares.
ETFs are still relatively new while mutual funds have been around for ages, so investors who aren’t just starting out are likely to hold mutual funds with built-in taxable gains. Selling those funds may trigger capital gains taxes, so it’s important to include this tax cost in the decision to move to an ETF.
The decision boils down to comparing the long-term benefit of switching to a better investment and paying more upfront tax, versus staying put in a portfolio of less optimal investments with higher expenses (that might also be a drain on your time, which is worth something).
Keep in mind that, unless you gift or bequeath your ETF portfolio, you will one day pay tax on these built-in gains. So you are often just deferring taxes, not avoiding them.
When you put money into a mutual fund, the transaction is with the company that manages it—the Vanguards, T. Rowe Prices, and BlackRocks of the world—either directly or through a brokerage firm. The purchase of a mutual fund is executed at the net asset value of the fund based on its price when the market closes that day or the next if you place your order after the close of the markets.
When you sell your shares, the same process occurs, but in reverse. However, don’t be in too great of a hurry. Some mutual funds assess a penalty, sometimes at 1% of the shares’ value for selling early (typically sooner than 90 days after you bought in).
Mutual funds can track indexes, but most are actively managed. In that case, the people who run them pick a variety of holdings to try to beat the index that they judge their performance against.
That can get pricey. Actively managed funds must spend money on analysts, economic and industry research, company visits, and so on. That typically makes mutual funds more expensive to run—and for investors to own—than ETFs.
Mutual funds and ETFs are both open-ended. That means that the number of outstanding shares can be adjusted up or down in response to supply and demand.
When more money comes into and then goes out of a mutual fund on a given day, the managers have to alleviate the imbalance by putting the extra money to work in the markets. If there’s a net outflow, they have to sell some holdings if there’s insufficient spare cash in the portfolio.
The Bottom Line
Given the distinctions between the two kinds of funds, which one is better for you? It depends. Each can fill certain needs. Mutual funds often make sense for investing in obscure niches, including stocks of smaller foreign companies and complex yet potentially rewarding areas like market-neutral or long/short equity funds that feature esoteric risk/reward profiles.
But in most situations and for most investors who want to keep things simple, ETFs, with their combination of low costs, ease of access, and emphasis on index tracking, may hold the edge. Their ability to provide exposure to various market segments in a straightforward way makes them useful tools if your priority is to accumulate long-term wealth with a balanced, broadly diversified portfolio.
