Going further afield than the US domestic market can find some exciting opportunities, writes Rudy Martin of Latin Stock Investing.

London-based insurance group Aviva (AV) is an insurance group providing long-term insurance and savings, fund management, and general insurance. Aviva serves over 43 million customers with long-term insurance and savings, general and health insurance, and fund management products and services.

Its business stretches from the United Kingdom to Europe, North America, and Asia Pacific, although a recent restructuring has resulted in the firm jettisoning many subsidiaries and affiliates. Under a new CEO appointed by an activist board of directors in November of last year, the trimmed-down firm seems poised for renewed growth.

Global biopharmaceutical giant AstraZeneca (AZN) discovers, develops, and commercializes prescription medicines for six areas of health care: Cardiovascular, Gastrointestinal, Infection, Neuroscience, Oncology, and Respiratory and Inflammation.

It has a range of medicines that includes treatments for illnesses, such as its antibiotic Merrem/Meronem, and Losec/Prilosec for acid-related diseases. AstraZeneca's products include Crestor, Atacand, Seloken/Toprol-XL, Plendil, Onglyza, Zestril, Symbicort, and Zoladex. The company owns and operates a range of research and development, production, and marketing facilities located across the globe.

Headquartered in London, AstraZeneca operates in over 100 countries, and has developed a promising pipeline of new products. Trading at slightly more than 11 times earnings and yielding 5.4%, AZN should produce steady returns to holders of its stock.

International media and education company Pearson (PSO) of London's principal operations are in the education, business information, and consumer publishing markets. The company delivers the content in a range of forms and through a variety of channels, including books, newspapers, and online services.

It offers services, as well as content, from test creation, administration, and processing to teacher development and school software. It publishes Penguin Books and the Financial Times.

The stock's 3.7% dividend yield, as well as its growing presence in testing services for professional designations, makes this a promising stock.

Online media firm SINA (SINA) serves China and the global Chinese communities with a digital media network of SINA.com, a mobile portal of SINA.cn, as well as a social media site, Weibo.com. The firm's capabilities enable Internet users to use their multimedia access to SINA portals to share their interests with other users.

SINA.com offers targeted professional content on each of its region-specific Web sites. SINA.cn provides its wireless users with information and entertainment content. The firm's revenues are primarily generated from online brand advertising, mobile value-added services, and various fee-based services.

The stock had been drifting since mid-January, then picked up in late April, and has recently been reaching new 2013 high ground.
