U.S. cell tower owners rallied today, possibly in response to the MetroPCS/T-Mobile deal. SBAC +2%. AMT +1.4%. CCI +2.8%. While the reverse merger will result in some duplicate cell sites being eliminated - American Tower just announced MetroPCS and T-Mobile share space on ~1,000 of its sites - it also puts T-Mobile's 4G LTE ambitions on better footing, both by increasing its spectrum assets and allowing the carrier to tap U.S. capital markets.
