Today’s investors face what seems like an ever growing variety of investment choices, with new mutual funds and exchange traded funds (ETFs) continuing to arrive. In recent years, actively managed, fixed income exchange-traded funds have appeared, combining the ETF structure with the potential to outperform an index.*

Trying to make sense of these different products doesn’t have to be overwhelming. Here is what to expect and some factors to consider as you weigh your investment objectives.

A brief history of funds and ETFs

For decades, investors have turned to traditional actively managed, open-ended mutual funds for an easy-to-use product to help them meet their financial goals and deliver the potential to outperform a benchmark (often a widely followed index).

In the early 1990s, financial product evolution expanded the set of investment vehicles available to investors with the creation of ETFs. ETFs gave investors intraday pricing and more discretion over the timing of their trades. Like stocks, ETFs give investors the ability to choose their market entry and exit points throughout the day, allowing them to try and take advantage of market developments in real time.

Then, in 2008, actively managed ETFs came on the scene. In these vehicles, a portfolio manager attempts to outperform an index versus replicating an index’s performance.

From an investor’s perspective, such ETFs offer a way to combine the potential advantages of active management in the fixed income universe with the trading flexibility of exchange-traded products.

Different products, different experiences

As you consider ETFs and open-ended mutual funds, it is important to recognize how the vehicles’ features can influence your experience. Buying and selling, pricing, disclosure, costs, holding period return, and tax implications can all be different (see the table below). For example, unlike with a traditional open-ended mutual fund, shareholder demand can influence an ETF’s market price, which can result in the shares trading at a premium or a discount to the ETF’s actual net asset value (NAV). The flexibility offered by ETFs—continuous pricing and the ability to place limit orders—means the return measurement is largely based on the market price return during the holding period rather than on the ETF's NAV.

Characteristics for actively and passively managed funds
Exchange-traded funds Open-ended mutual funds
Buying and selling
  • ETFs are continuously priced throughout the trading day, and investors buy and sell them in the secondary market (stock market).
  • ETF investors place orders through a brokerage account, which allows them to place limit, stop-limit, and short-sale orders, and to trade on margin.
  • Investors transact directly with the mutual fund.
  • Mutual fund investing does not require a brokerage account.
  • Investors cannot buy mutual funds on margin, or set price limit orders.
  • Share prices fluctuate intraday on a stock exchange and have bid and offer prices.
  • Price may differ from the NAV and trade above (premium) or below (discount).
  • All shareholder orders receive the same daily price—NAV—calculated at 4:00 p.m. Eastern time.
  • Daily disclosure of portfolio holdings to market participants
  • Indicative Optimized Portfolio Value (IOPV)—released to the exchange every 15 seconds during trading hours
  • Disclosure of the number of days shares traded at a premium/discount for the previous year
  • Disclosure of performance at NAV and market
  • Generally, disclosure of portfolio holdings monthly/quarterly with a lag
  • Disclosure of NAV performance
Trading costs
  • Brokerage commission plus bid/ask spread (difference between) on each buy and sell order
  • None for a no-load fund when bought directly through fund company
Holding period return
  • Market price return (plus distributions)
  • Change in NAV (plus distributions)
Tax implications
  • Possibly more tax efficient because investor trades can be matched on secondary market versus in the fund
  • When investor redemptions are not offset by cash inflows from investors, the redemptions can trigger portfolio trading, which may have tax implications for shareholders.
† ETFs and mutual funds are subject to management fees and other expenses.

Which vehicle is right for an investor?

Typically, the best way for an investor to choose between investment vehicles is to accurately identify his or her personal investment horizon and objectives. Consider the following types of investors and their varied objectives.

Saving for a long-term goal

Are you saving toward a long-term goal such as buying a house in five to seven years in a brokerage account? Some brokers may offer the option to automatically invest a set amount each month from your paycheck, which may be appealing. You may also be able to set up a regular purchase program for an open-ended mutual fund from a bank account. This automatic feature is generally not available on an ETF. In these account types, with an ETF, you would generally have to manually place buy orders for each trade.

In this example, the availability of automatic investing could make a traditional open-ended mutual fund more appropriate to meet the investor’s goals.

Active trader

If you prefer to manage your own accounts and want the flexibility to trade during market hours to implement your preferred investment strategies, ETFs can offer the flexibility to meet your needs. Similar to stocks, ETFs can be traded throughout the trading day and on margin. Investors also have the ability to set limit orders and sell short. Most open-ended mutual funds can only be purchased at their closing prices, or NAVs. ETFs offer daily holdings transparency, allowing investors to review holdings and monitor portfolio risk exposures more frequently than with traditional open-ended mutual funds.

In this example, ETFs may satisfy the investor’s need for more trading flexibility and holdings transparency.

Retirement investor

Consider investors weighing options for their established retirement portfolio. With a long-term view, they may not want to devote a lot of time to worrying about the intricacies of an active trading strategy and they want to avoid the potential of buying (selling) shares at a premium (discount). Open-ended mutual funds are available with no loads, no commissions, and no transaction fees. Moreover, mutual funds are bought and sold at their NAV, so there are no premiums or discounts. While an ETF also has a daily NAV, shares may trade at a premium or discount on the exchange during the day.2 Investors should evaluate the share price of an ETF relative to its indicative NAV.

In this example, a traditional open-ended mutual fund could be an investor’s preferred option due to its simplicity.

(Fidelity believes that workplace savings plan participants and savers using other tax-advantaged accounts seeking passive market exposure should weigh the features and benefits of index mutual funds and index ETFs carefully. The potential features an investor may experience when holding index ETFs—tax advantage, intraday trading, trading at a premium or a discount to NAV—are either not meaningful to 401(k) investors (tax advantage) or pose opportunities that Fidelity believes are not in line with sound retirement-savings practices: intraday trading and trading at a potential premium/discount to NAV.)

Investors in a high tax bracket

Investors in a high tax bracket may be interested in investments that offer tax efficiency for their taxable assets. In this scenario, if an investor finds that an open-ended index mutual fund and an index ETF are similar relative to his or her investment objectives, the passively-managed ETF, in general, has the potential to be more tax efficient than the index mutual fund. Actively managed fixed-income ETFs, as well as some actively managed equity ETFs also have these same potential tax advantages versus actively-managed mutual funds.3 However, we caution investors against making long-term investment decisions based solely on any potential tax benefits. Investors should evaluate how an investment option fits with their time horizons, financial circumstances and tolerance with market volatility, as well as cost and other features.

In this example, the investor may choose ETFs to take advantage of the potential for a greater degree of tax efficiency.


While mutual funds and ETFs are different, both can offer exposure to a diversified basket of securities and can be good vehicles to help meet investor objectives. What is important is for investors to pick the best choice for their specific investing needs, whether an ETF, an open-ended mutual fund, or a combination of both.

Here are some points to consider when weighing vehicle options:

  • Is the ability to execute fund trades at prevailing prices throughout the trading day important? Consider ETFs.
  • Is there a preference for trading a fund at NAV without paying a load and avoiding the potential of paying a premium at purchase (discount at sale)? Consider no-load mutual funds.
  • Is the flexibility of trading on margin important? Consider ETFs.4
  • Is dollar cost averaging part of your investment strategy? Consider the automated savings features of mutual funds.
  • Is it important to know a fund’s holdings each day? Consider ETFs.
  • Make sure to consider all costs and expenses related to any investment vehicle.
  • Do the benefits of both ETFs and mutual funds have the potential to help meet investment goals? Consider building a portfolio incorporating both types of vehicles to gain exposure to different asset classes.

*Although actively managed mutual funds and ETFs have the potential to outperform an index, this is not guaranteed and the funds may trail the index.
ETFs are subject to market volatility and the risks of their underlying securities which may include the risks associated with investing in smaller companies, foreign securities, commodities and fixed income investments. Foreign securities are subject to interest rate, currency- exchange rate, economic and political risk all of which are magnified in emerging markets. ETFs that target a small universe of securities, such as a specific region or market sector are generally subject to greater market volatility as well as the specific risks associated with that sector, region or other focus. ETFs which use derivatives, leverage, or complex investment strategies are subject to additional risks. The return of an index ETF is usually different from that of the index it tracks because of fees, expenses and tracking error. An ETF may trade at a premium or discount to its Net Asset Value (NAV). The degree of liquidity can vary significantly from one ETF to another and losses may be magnified if no liquid market exists for the ETF’s shares when attempting to sell them. Each ETF has a unique risk profile which is detailed in its prospectus, offering circular or similar material, which should be considered carefully when making investment decisions.
Short selling and margin trading entail greater risk, including but not limited to risk of unlimited losses and incurrence of margin interest debt, and are not suitable for all investors. Please assess your financial circumstances and risk tolerance prior to short selling or trading on margin.

2. An ETF that is trading at a premium has a market price higher than its NAV; therefore, an investor would pay more for the ETF than its holdings are actually worth. And if an ETF is trading at a discount, its market price is lower than its NAV, so the investor would buy the ETF for less than the value of its holdings.
3. Regular ETF investors trade shares with other investors through the stock exchange instead of with the fund. As a result, many investor trades do not trigger transactions in the fund, which could result in capital gains. If an investor sells in a traditional open-ended mutual fund, the transaction is between the investor and the fund, which may create the need for the portfolio to sell securities to raise the cash needed to meet the redemption, which may trigger a capital gain for all the mutual fund’s shareholders.
4. Certain ETFs are not marginable until 30 days from settlement.
