Key Data Points
Foolish take
About $30 million of stock sales is a sizable chunk of change, but it was spread across 8 different people who presumably have T-Mobile US shares included in their compensation packages. Moreover, it's barely a blip on the radar in the context of Deutsche Telekom's dominant ownership of its American subsidiary.
So I would hesitate to draw any conclusions from this pre-planned stock sale. It's just another round of stock-based compensation playing out on the open market. Deutsche Telecom remains T-Mobile US's largest shareholder by a mile, firmly committed to the company's long-term success.
And the remote-controlled strategy has worked wonders so far. T-Mobile US started out as a minor player in the American mobile service market, but now boasts the largest market cap among the big 3 networks -- and it keeps growing much faster than AT&T (T 2.18%) and Verizon Communications (VZ +2.26%). The stock isn't cheap, but T-Mobile US earned its premium valuation through superior business results.
