Verizon's stock price rose 29% to $50.14 as of last Friday's close, outperforming the S&P 500's 13% gain, and the company raised its full-year adjusted EPS guidance to $4.99-$5.04. During the same period, AT&T's stock price increased by 7% to $25.68, and it accelerated share buybacks to approximately $10 billion. T-Mobile's stock price fell 9% to $181.52, despite a 7.9% increase in second-quarter revenue, due to narrowing subscriber growth advantages and intensified competition.
