Understanding ETFs

1. What is the difference between ETFs and mutual funds or stocks?

iShares ETFs combine popular features of both. Like a mutual fund, an ETF is a collection of stocks or bonds.

Quote: Like a stock, you can buy and sell an ETF whenever the market is open

Percent of iShares Core ETFs that have Outperformed Mutual Funds

Chart: Percent of ETFs that Outperform Comparable Mutual Funds

Source: Morningstar, as of 1/31/2016. Post-tax comparison between the 1, 3 and 5 year returns at NAV of the iShares Core ETFs and the oldest share class of active open-end mutual funds within the same Morningstar categories as the iShares Core ETFs. Mutual funds are generally more tax inefficient than ETFs and, as a result, are typically more negatively impacted than ETFs when comparing performance based on post-tax returns rather than total returns. The number of ETFs and mutual funds used for each period varies based on the inception date of the iShares Core ETFs. iShares Core ETFs included in this comparison vary based on the time period analyzed: 1 year (19 Core ETFs existed for the full 1-year period ended 1/31/15); 3 year (15 Core ETFs existed for the full 3-year period ended 1/31/13); and 5 year (9 Core ETFs existed for the full 5-year period ended 1/31/11). iShares Core ETFs outperformed their active mutual fund peers by 80.6% (1955/2426), 83.6% (1804/2157) and 87.8% (1330/1515) over the 1, 3 and 5 year periods ended 1/31/16, respectively. Performance was averaged for Morningstar categories containing more than one iShares fund, and may be different for other time periods. Returns are calculated after taxes on distributions, including capital gains and dividends, assuming the highest federal tax rate for each type of distribution in effect at the time of the distribution. Past performance is no guarantee of future results. For more information on the differences between iShares ETFs and mutual funds, click here.

3. Are ETFs professionally managed?

iShares ETFs are overseen by some of the most experienced portfolio managers in the industry. Our fund managers aim to ensure the ETF does what it’s supposed to do. This includes seeking to closely match the ETF to its benchmark index, and minimizing the potential for unwanted capital gains distributions.

ETFs differ from actively managed funds, in which the manager generally attempts to "beat" the market’s performance, which often comes with higher fees and taxes. Beating the markets – especially after fees – can be quite challenging.

4. How to buy an ETF?

Buying iShares ETFs is easy. They offer the same trading flexibility as stocks, meaning they can be bought and sold during market hours but with the added potential benefit of being diversified.

5. How do you use ETFs in your portfolio?

  • Many investors use them to pursue long term goals, such as funding their retirement or growing wealth.
  • Others take advantage of ETFs to help achieve specific goals, such as generating income or cushioning against jumpy markets.
  • And those with strong market views use ETFs to potentially capture timely new opportunities, instead of picking individual stocks or bonds. Read more about how to use an ETF.

Carefully consider the Funds' investment objectives, risk factors, and charges and expenses before investing. This and other information can be found in the Funds' prospectuses or, if available, the summary prospectuses, which may be obtained by visiting the iShares ETF and BlackRock Fund prospectus pages. Read the prospectus carefully before investing.

Investing involves risk, including possible loss of principal.

Transactions in shares of ETFs will result in brokerage commissions and will generate tax consequences. All regulated investment companies are obliged to distribute portfolio gains to shareholders.

Certain traditional mutual funds can also be tax efficient.

Diversification and asset allocation may not protect against market risk or loss of principal.

Investment comparisons are for illustrative purposes only. To better understand the similarities and differences between investments, including investment objectives, risks, fees and expenses, it is important to read the products' prospectuses.

When comparing stocks or bonds and iShares Funds, it should be remembered that management fees associated with fund investments, like iShares Funds, are not borne by investors in individual stocks or bonds.

The performance quoted represents past performance and does not guarantee future results. Investment return and principal value of an investment will fluctuate so that an investor’s shares, when sold or redeemed, may be worth more or less than the original cost. Current performance may be lower or higher than the performance quoted. Performance data current to the most recent month end may be obtained by visiting the products' respective overview pages.
