Shares of T-Mobile (TMUS) rose sharply in trading on Thursday due to a rumor that the company was the potential target of a takeover. This is not the first time TMUS has been the subject of such rumors in recent history, but just as before there is no confirmation that an actual bidder has emerged. Nevertheless, TMUS shares closed up +3.10% to settle at 60.44. Keep an eye on the stock for further developments. It is also worth noting that David Tepper’s hedge fund Appaloosa Management acquired a 3.86 million share position in TMUS in the fourth quarter of 2017.
