Communications sector takeaways for investors
The communications sector comprises a diverse range of companies, but they can be divided into two primary groups: telecommunications and information technology (IT). Those who want to invest in this sector could start by narrowing down the type of communications company they're interested in.
Wireless companies are common at the top of this market sector. They make up half of the 10 largest communications services companies. Although they sometimes underperform the overall stock market, these companies are often good dividend stocks. Another point in their favor is that the recent import tariffs don't affect their businesses as much as other types of companies.
IT companies, on the other hand, tend to be growth stocks. Alphabet and Meta are two notable examples, with each having experienced rapid growth. But advertising is a big revenue driver for many of these companies, including Alphabet and Meta. They could see their bottom lines affected by the Trump administration's tariffs, as businesses cut back on ad spending to protect their bottom line.
That could lead to short-term turbulence, but the best communications companies will be able to adjust. Whether you choose telecommunications companies, information technology companies, or both, there are valuable investment opportunities among the best communications stocks.
