How The Streak Compares With The Market
Over the same 6 trading days, the S&P 500 returned +0.7% including dividends, so the run is mostly T-Mobile US’s own story rather than the market’s. 3 other S&P 500 stocks are currently on winning streaks of 6 days or longer. Over the past three months the stock is down 5.6%, a window that includes the streak; over the other 57 sessions of that window it was down 15.3%.
Is The Business Keeping Up With The Stock?
On the fundamentals, revenue grew 9.3% over the last twelve months, against a median of 9.1% for S&P 500 Communication Services stocks; its operating margin is 20.7%, versus a median of 21.1%; and the stock trades at 16.3 times trailing earnings against a median of 18.1. The read is mixed: revenue growth above the median and a multiple below the median on one side, margins below the median on the other.
A climb like this is worth respecting, and worth testing. Our Guidance Momentum screen tracks the stocks whose companies just raised their own forward numbers.
Prefer the theme to the single name? A communication services ETF like XLC holds the whole group, not just this stock. It is still a concentrated bet on one theme, which is the gap the portfolio below is built to close.
Momentum Is A Tailwind, Not A Plan
Riding a stock that rises every day feels effortless, and that is precisely the danger: the same momentum that built this run can reverse without notice, and one name’s reversal should never be able to reset your whole year.

It has a track record of outpacing a benchmark that combines the S&P 500, the S&P MidCap 400, and the Russell 2000. Watch the runs; own the resilience.
