The market is going to narrow in the month ahead as we move into summer, and that means investors are going to become more selective in their stock picks. Investors are only going to reward the companies with the best forecasted sales and earnings growth, and are going to move into larger companies with greater international sales to decrease their exposure to potential market shocks in any one country.

There’s a lot going on in the world, but the complexity of the global economy only means that there are several opportunities to profit. Even in Europe where the financial leadership is bogged down by bailout packages and debt reduction, there are several stocks that have popped up on my screens. So today, I have three exciting global stock names to share with you today

Global Stock #1 – Novo Nordisk A/S (NVO)

Novo Nordisk A/S (NYSE: NVO) is the first global stock I’d recommend for this summer, and it comes from Denmark. The company is the world’s largest producer of insulin, the hormone used to treat diabetes, an ever-growing disease worldwide. As developing nations become more prosperous, middle-class citizens are developing more Western-style tastes and, in turn, this is leading to higher rates of diabetes. While this is a major concern for global health advocates, for companies that develop diabetes drugs, this is a positive development. And there is little evidence that this trend will reverse course anytime soon.

The numbers tell the story here. In its most recent quarter, NVO announced a 23% earnings increase. Its blockbuster insulin drug, Victoza, experienced 191% sales growth in the quarter. The company will launch this drug in China in the second half of 2011, and this will provide a further sales boost. NVO is an excellent stock to own this summer, and I expect continued strong performance from the company as it reports more stellar earnings.

Global Stock #2 – CPFL Energia S.A. (CPL)

CPFL Energia S.A. (NYSE: CPL) is another strong summertime global stock. This company is an electric utility based in Sao Paulo, Brazil. Brazil is one of the fastest-growing economies right now, and as it produces more, it is consuming more energy. This is great news for energy sector plays like CPFL.

The company distributes electricity to 6.4 million customers in 570 communities in the states of Sao Paulo and Rio Grande do Sul in Brazil. The company also owns hydroelectric power plants and trades wholesale power in the open market.

On top of its remarkable growth potential, the company offers an outstanding dividend of 3.81%. This will give you a nice steady stream of income over the summer months. The company has been in talks to merge with another energy company in Brazil, and the successful completion of a merger could really boost shares.

Global Stock #3 – Chunghwa Telecom Co. Ltd. (CHT)

Chunghwa Telecom Co. Ltd. (NYSE: CHT) is my third summer global stock pick. This company is the top telecommunications provider in Taiwan. The company offers local and long-distance phone services, wireless services and Internet access to subscribers across Taiwan. In addition, the company is expanding into new industries, most notably cloud computing. Chunghwa’s data center services include multi-tier storage, firewall security and redundant bandwidth.

The Chinese telecommunications market is incredibly strong right now as more customers look to sign up for wireless phone services and Internet access. In its latest quarter, the company reported a revenue increase of 5.8%, with a 38.6% sales gain in its mobile value-added services segment. This is among the higher-growth segments that have propelled major telecommunication companies in the United States, like Verizon Communications (NYSE: VZ) and AT&T (NYSE: T).

This is an excellent play and a perfect pick to wade you through any summertime volatility.
