The telecom sector is booming in general. Verizon and AT&T (T 1.63%) crushed their Dow Jones (^DJI 0.39%) peers this year. Smaller rival Sprint Nextel (S) skyrocketed even higher thanks to a turnaround story based on smartphones and high-speed data connections. Verizon's story is similar, except the company didn't have a near-death experience in 2011, as Sprint did. Instead, the company is building a long-term success story, brick by boring brick. Sprint might be exciting, but Verizon is the kind of reliable performer that builds wealth while helping you sleep at night.

These gains still leave plenty of room for further growth. You pay just $7.20 for every dollar of Verizon's free cash flow. That's the kind of deep discount that makes value investors reach for their wallets. Let's put the ratio in the context of telecom rivals and a familiar value-hound favorite:

Sprint appears well on its way to a major cash infusion from Japanese peer Softbank -- and a subsequent merger with data network operator Clearwire (NASDAQ: CLWR). T-Mobile found another partner in MetroPCS (TMUS -0.83%). The pack of smaller networks chasing Ma Bell and Big Red just isn't going away.
