U.S. Stock Movement: Comcast spinoff sparks competition concerns, leading to sharp declines among the three major U.S. mobile carriers

Glonghui, June 29 | After Comcast announced a spin-off plan, the three major U.S. mobile operators experienced a collective sell-off. Verizon led the decline with a drop of 4.9%, followed by a 4.1% drop for AT&T, and a 2.9% drop for T-Mobile. The market is concerned that Comcast, by spinning off NBCUniversal and Sky, will focus more on its cable communications business, which could reshape industry competition and put pressure on traditional mobile operators.
