T-Mobile's First Dividend: The End of the Growth Stock Era?

T-Mobile US (TMUS) has been a stellar performer in the American telecom scene, as it gained considerable market share over its rivals - including AT&T (T) and Verizon (VZ) - through the years. Undoubtedly, staying competitive in the wireless and fiber markets does not come cheap, especially in a higher-interest rate environment.
