A utility exchange-traded fund (ETF) offers an efficient way to invest in a broad selection of electric, water and natural gas companies, and other firms operating in the utilities sector of the economy. The top five utility ETFs offer investors unique options to gain exposure to the utility equities that best match their investment needs. These include ETFs focused on American utilities broadly, on small-cap or large-cap American utilities, or on international utilities.
1. Utilities Select Sector SPDR ETF
The Utilities Select Sector SPDR ETF (NYSEARCA: XLU) seeks to track the investment performance of the Standard and Poor's Utilities Select Sector Index. This index is a sectoral subset of the S&P 500 Index, which focuses on large-cap companies in the United States. The Utilities Select Sector Index includes leading American electric utilities, gas utilities, water utilities, power producers and energy traders. XLU attempts to replicate the performance of the underlying index by investing in the same stocks in the same proportions as the index whenever possible. In normal conditions, no less than 95% of the fund's assets match those held in the index.
As of November 2015, XLU has net assets of nearly $6.7 billion across 31 stocks. The top five holdings in the fund are Duke Energy Corporation at approximately 8.6%, NextEra Energy at 8.4%, Dominion Resources at 7.9%, Southern Company at 7.6% and American Electric Power Company at 5.3%. The top 10 holdings together account for 60% of the fund's assets. Electric utilities account for about 56.5% of the fund, while multi-utilities account for 39.8%. Multi-utilities are companies that operate in multiple industries within the sector. XLU has a very low expense ratio of 0.14%.
2. IShares U.S. Utilities ETF
The iShares U.S. Utilities ETF (NYSEARCA: IDU) is a good option for investors looking for wider exposure to the U.S. utilities sector. While XLU focuses only on large-cap utilities, IDU provides some exposure to small- and mid-cap utilities as well. IDU attempts to match the investment results of the Dow Jones U.S. Utilities Index. This index is a subset of the Dow Jones U.S. Market Index, which includes the top 95% of U.S. stocks based on float-adjusted market capitalization. IDU uses a representative sampling strategy to approximate the investment profile of the underlying index rather than attempting to replicate the index in full.
As of November 2015, IDU has net assets of about $571 million across 60 stocks. Since IDU's underlying index is weighted according to market capitalization, the fund's top 10 holdings are all large-cap companies. Among the top five holdings, Duke Energy Corporation has an allocation of approximately 7.7%, while NextEra Energy is allocated at 7%, Dominion Resources at 6.5%, Southern Company at 6.3% and American Electric Power Company at 4.3%. The top 10 holdings together account for about 50% of the fund's assets. The electric utility industry accounts for 52.8% of the fund, while multi-utilities account for 35.2% and natural gas utilities account for 6.6%. IDU has an expense ratio of 0.43%.
3. IShares Global Utilities ETF
The iShares Global Utilities ETF (NYSEARCA: JXI) provides exposure to gas, water and electric utility companies around the world. The fund is designed to track the investment performance of the S&P Global 1200 Utilities Sector Index. This index is made up of utility companies deemed to be important to global equities markets. It is a sectoral subset of the S&P Global 1200 Index. JXI employs a representative sampling strategy to match the investment profile of the underlying index and produce corresponding investment results.

Electric utilities account for 52.5% of the fund, while multi-utilities and gas utilities make up 36.6% and 7.2% of the fund, respectively. JXI has an expense ratio of 0.47%.
4. Invesco S&P SmallCap Utilities ETF

Companies in the index are weighted according to market capitalization under a free-float methodology to account for shares not available on the open market.
