T-Mobile Plunges 2.56% on $1.22B Volume, Ranking 98th Amid Regulatory and Legal Pressures

T-Mobile US (TMUS) closed 2.56% lower on Oct. 1, 2025, with a trading volume of $1.22 billion, ranking 98th in market activity. The decline followed regulatory scrutiny over spectrum allocation delays and ongoing litigation with Dish Network regarding 5G infrastructure commitments.

Analysts noted mixed sentiment as the carrier faces pressure to accelerate network expansion amid rising competition from satellite broadband providers. A Federal Communications Commission inquiry into its C-band deployment schedule has raised concerns about potential penalties, while a court ruling on its contract obligations with Dish remains pending.

To evaluate the "buy top-500 most-active stocks daily" strategy: The back-testing framework requires either a proxy index (e.g., SPY) for large-cap exposure or a custom portfolio return series. A simplified one-day in-and-out strategy on SPY from Jan. 1, 2022, to present could approximate daily rebalancing. For precise testing, a manually imported dataset of the exact top-500-by-volume basket would be needed. Alternatively, a single-stock analysis of each day's volume leader could provide event-driven return insights.
