Why Is AMERICAN TOWER CORP REIT (AMT) Stock Up Today?

American Tower Corp REIT (AMT) shares rose 8.43% to close at $180.78 on Friday. The primary driver of the move was news that SpaceX could become a major new customer for U.S. cell tower operators as it expands into wireless services. This development sent tower stocks soaring while carrier stocks slid, with T-Mobile tumbling 12% in the same session.

The session low was recorded at the open at $166.73. The stock finished the day at $180.94.
