Shares have come under pressure as the recent selloff takes hold, with the 1-year total shareholder return now negative at nearly -12%. Momentum is clearly fading after several years of outperformance. While the company delivered strong multi-year returns of 38% and 63% for three- and five-year total shareholder return respectively, the current pullback suggests investors are reassessing T-Mobile’s valuation in light of cooling growth and shifting market sentiment.
