Both MetroPCS (NYSE:PCS) and Leap (NASDAQ:LEAP) suffered losses in share value by as much as 9 percent each following reports of added new subscribers in the last quarter of 2011 that did not meet analysts’ forecasts.

Wednesday afternoon, Leap reported adding 175,000 new customers during that time, while analysts projected additions of 195,000 or more. Thursday, MetroPCS reported similarly disappointing new subscriber numbers, with 197,000 rather than the 214,000-250,000 hoped for by analysts.
