On CAPS, 91% of the 766 members who have rated American Tower believe the stock will outperform the S&P 500 going forward. These bulls include Clint35 and AcheronRecords.

Earlier this week, Clint35 touched on American Tower's plans to convert into a REIT: "I wanna get in on the upcoming dividends. This one still has a lot of room to grow as well, especially in emerging markets."

American Tower even boasts a rather robust three-year average operating margin of 40%. That's much higher than those of main rivals Crown Castle (29%) and SBA (12.4%).

CAPS member AcheronRecords elaborates on the American Tower bull case:

Moving to REIT status by January 2012 to get the tax benefits and to start distributing income to shareholders. Long term wireless towers are going to be needed more and more to support all the smartphone and tablets coming to market. They also are making inroads in developing countries. It seems pricey now, but I think that the earnings potential are worth it and payouts to shareholders will make it worth the wait.
