Summary
Point72 Asset Management, L.P. established a new $341.2M equity position in T-Mobile US during the third quarter of 2025, according to SEC 13F filings released on November 14, 2025. The position reflects Point72's holdings as of September 30, 2025, and marks a notable addition to the multi-billion-dollar hedge fund's portfolio, which also includes substantial holdings in NVIDIA, Amazon, and other technology and infrastructure stocks.
The $TMUS investment comes at a complex time for the telecom sector, characterized by mixed institutional sentiment. Over the most recent quarter, 911 institutional investors added shares of T-Mobile while 842 reduced their positions, indicating no clear consensus among the professional investment community. However, several high-profile institutional moves have been substantial. Most notably, SoftBank Group reduced its stake by 21.5 million shares (a 25.2% decline) for an estimated $5.1 billion in Q2 2025, signaling a significant de-risking by one of the company's largest historical shareholders. Conversely, Wellington Management increased its position by 4.3 million shares (+47.5% to approximately $1.04 billion) in Q3, while Jane Street and D.E. Shaw & Co. made aggressive moves, increasing their stakes by 1,283.5% and 1,336.0% respectively.
The insider trading activity presents a potentially cautionary signal for prospective investors. Over a six-month period, T-Mobile insiders executed 413 transactions, but the distribution was heavily skewed toward selling: only 1 purchase versus 412 sales. This overwhelming insider selling pressure, while not uncommon in equity markets, may warrant monitoring by portfolio managers evaluating the risks associated with telecom equities.
Notable exits by established institutional investors have also occurred. Berkshire Hathaway completely liquidated its $TMUS position during Q2 2025, selling 3.9 million shares for approximately $925 million, while Ghisallo Capital Management exited its entire position in Q3, liquidating 2.25 million shares valued at roughly $539 million. These departures by established value-oriented investors contrast with Point72's entry and Wellington's expansion, suggesting divergent long-term outlooks on the company's fundamentals and valuation.
