Speaking of the general trend that investors should pay attention to in the next few years, the global 5G (or fifth generation technology) telecommunication network construction should be close to the peak. After all, as consumers become more and more addicted to smart phones, everything from doorbell to dishwasher can now be connected to your home Wi-Fi to increase digital functions. Recently, we have seen the rapid growth of data consumption. These devices bring a real burden to the network, so the telecommunications industry is racing to keep up with this trend and support the future digital economy. Investors should not choose individual telecom and technology stocks that may benefit from this phenomenon, but should rely on the following 5G exchange-traded funds to gain exposure to this long-term trend.

As one of the largest telecom-related ETFs, the total assets under management are about $3 billion. This pioneer fund is one of the simplest and most liquid ways to participate in the 5G revolution. It has contacted all well-known brands, from service providers such as Verizon Communications (VZ) and Comcast Corp. (CMCSA) to Internet and cloud computing giants such as Google's parent company Alphabet (GOOG, GOOGL). If you want to promote the fact that people rely heavily on data services and will only use more bandwidth in the future, VOX is a simple way to reach out to leading brands in technology and telecommunications. The annual expense rate of this fund is 0. 1%, that is, every investment of 10,000 dollars is10 dollars.

Like VOX, this iShares telecom fund excludes large technology leaders close to the top of VOX, such as Facebook (FB), and focuses entirely on actual service providers. Because the competition in this field is not completely famous in the United States, this means that about 40% of the funds are in Verizon and AT & amp； T (T) is in the hands of two giants. If you are not afraid of this centralized approach, IYZ is the best way to play the role of the actual connection provider. It is worth noting that due to the high yield of large telecom stocks like duo, this iShares fund offered a generous dividend yield of 3% as a sweetener. IYZ's expense rate is 0.42%.

This global telecom fund has expanded IYZ's geographical coverage, set its sights beyond Verizon and Alphabet, and brought Asian Internet giant Tencent Holdings (0700.HK) to its top position. Considering the size of these large American companies, the portfolio is still mainly composed of domestic stocks, because North American companies account for about 70% of the total portfolio. But what about those who don't want to go all out? For those who have invested in some top-heavy funds before, the fund's footprint is slightly more diversified. The expense ratio of 5G ETF is 0.46%.
