Investors have been fleeing European stocks as concerns have mounted over sovereign debt levels on the continent. Fool analyst Jordan DiPietro says there are legitimate concerns about that debt, however, a lot of stocks have been battered unfairly, and foreign telecoms happen to be an area that looks particularly attractive. DiPietro thinks Telefonica, which is a Spanish company, has some great prospects and is trading at a really reasonable price. To see DiPietro's full thoughts on Telefonica, watch the video, then read on below:

Right now, there's definitely plenty of beaten-down foreign telecom companies to choose from. Telefonica competes with Vodafone (NYSE: VOD), France Telecom (NYSE: FTE), America Movil (NYSE: AMX), and a handful of other companies. DiPietro likes Telefonica because it has been lumped in with the Spanish economy, so investors are nervous about it right now. However, about 65% of its revenues come from outside of Spain, and it has a really dominant presence in Latin America. It recently reached an agreement with Portugal Telecom to acquire its 50% stake in Vivo, which is Brazil's largest mobile operator. This makes Telefonica the No. 1 provider in a country that has more than 150 million cell-phone users.

Looking at its forward P/E multiple of 8.9, Telefonica is trading well below its five-year historical average. In addition, shares are around $70, and DiPietro assesses its fair value at about $84, which means there's at least a 20% margin of safety. Add to that a solid 5.8% dividend yield, and you've got a really stable company that's significantly undervalued.
