For 25 years, Steven Halpern, editor of TheStockAdvisors.com, has surveyed the leading financial newsletter advisors asking for their favorite stocks for the coming year. This article is one of 100+ ideas in the Best Stocks for 2008 report.

"My favorite conservative investment idea for 2008 is Millicom International Cellular S.A. (NASDAQ: MICC)," says Nick Vardy, editor of The Global Stock Investor.

"The explosion in cell phone usage is one of my favorite 'top down' themes in global investing. No technology has spread wider and more quickly than cell phones. While it took TV 30 years to penetrate households across the globe, cell phones managed to achieve this in less than a single decade.

"My top pick to profit from this theme is Luxembourg-based Millicom International Cellular S.A., the 'Indiana Jones' of the cell phone industry. The company is one of a handful of global players that are profiting from expansion in cell phone markets where others fear to tread.

"Millicom's strategy has been unique and daring. It has cobbled together a patchwork empire that consists of 16 countries in Central America, South America, Africa, South and Southeast Asia. Today Millicom has 20 million subscribers.

Last December, over 100 stocks were featured in our Top Picks for 2007 report. Now, at mid-year, we turn to the 20 advisors whose picks showed the strongest gains to get an update on their previous picks, as well as a new favorite stock for the second half of the year.

Nick Vardy, editor of the Global Stock Investor, chose América Móvil (NYSE: AMX) as his favorite stock for 2007, which rose 38% as of 6/1/07. Here is his original recommendation for AMX and his current opinion on the stock.

For his new favorite idea for the second half of 2007, the advisor looks to Millicom International Cellular (NASDAQ: MICC), which he calls, the "Indiana Jones" of the global cell phone industry. He explains, "Luxembourg-based Millicom is one of a handful of global players that are profiting by expanding in cell phone markets where others fear to tread.

"Its strategy has been unique and daring. While the Vodafones and América Móvils of the world slug it out in big cell phone telecommunications markets such as Brazil and India, Millicom has cobbled together a patchwork empire that consists of 16 countries in Central America, South America, Africa, and South and Southeast Asia.

"In total, Millicom's cellular operations are licensed to serve a combined population of approximately 278 million people -- roughly the population of the United States. Millicom has focused on offering prepaid cell phone services in countries where landlines are inadequate.

"Although most of Millicom's sales growth occurs in traditional Latin American markets, more than half of Millicom's customers are in Africa and Asia. And that's where much of Millicom's future growth lies. Given the relatively low cell penetration rates, Africa is the fastest-growing region of the world for cell phone use.
