The telecom titan

Given the low-risk nature of its business and its stock's current 4.2% dividend yield, Verizon Communications (VZ 0.03%) offers investors two important benefits: capital preservation and income generation.

The telecom giant's subscription-based, utility-like business generates strong and stable cash flow that helps to insulate its stock from wild price swings. This lower volatility makes it less likely an investor will suffer a large loss should an unexpected need to sell shares arise in the near-term.

Moreover, Verizon's cash flows remain well insulated from the competition. Verizon's network consistently ranks as the best in the industry, even as rivals such as T-Mobile US (TMUS 0.19%) and Sprint (S) claim that they're chipping away at its lead. That's helped Verizon continue to add postpaid wireless subscribers -- who are generally the most profitable and sought-after customers -- despite heavy promotions from T-Mobile, Sprint, and other competitors.

Looking ahead, Verizon offers investors a safe-yet-attractive play on increasing internet connectivity and rising data usage. The company is well positioned to lead the transition to 5G networks, which could provide it with exciting new opportunities in the home broadband market. Additionally, Verizon has been steadily acquiring assets to strengthen its Internet of Things technology. The company is making clear progress in the segment, with revenue growth from IoT services rising 24%, to $217 million, in the third quarter. And although the business is currently small (by Verizon's standards), the massive potential of the Internet of Things could help this segment develop into a significant source of Verizon's revenue and profits in the years ahead.

Together, these growth opportunities ought to help Verizon improve its already impressive cash flow generation, which should, in turn,  allow the telecom titan to continue to do what it's done consistently over the past decade: reward its shareholders with steadily rising stream of dividend income.
