Readers of this space know that the investment bias favors U.S.-based companies, but there are exceptions, and America Movil SAB de CV (NYSE: AMX) is one.

America Movil, or just Movil, the largest cell phone service provider in Latin America, is another one of those large caps that was rudely treated by Wall Street, which took shares down to about $25 from the mid-$60s in FY2008.

While domestic phone companies battle for market share, non-US firms are building dominant positions in markets considered by many to offer higher growth potential, such as Latin America. And despite their foreign operations, several of these stocks are traded through ADRs on the New York exchange.

John Christy III, editor of the Forbes International Investment Report is a fan of America Movil (NYSE: AMX), the dominant mobile phone company in Mexico, with operations in a dozen other Latin American countries. The company is controlled by billionaire Carlos Slim Helu, the world's third-richest man (following Bill Gates and Warren Buffett).

Says Christy, "American Movil has had a stellar record of growth and profitability over the past five years. With cellular penetration rates in Latin America hovering in the 40% range (versus 90%+ in Europe), there is a lot more room for growth."

The shares have risen 15% since he first added it to his portfolio two months ago, and he cautions that they might pull back. However, he says, "Use dips as an opportunity to scoop up more shares. AMX is trading at less than 15 times next year's consensus earnings forecast of $2.90. With estimated earnings growth running at a 35%+ clip, AMX still looks extremely attractive."
