Yum Brands (NYSE: YUM) may provide a boost to food and consumer sector exchange traded funds after the fast food giant reported quarterly results after Wednesday’s closing bell and raised its 2011 profit outlook.

The company, which brands include KFC and Taco Bell, has been able to offset slower U.S. sales by expanding in China. Yum shares rose in after hours trading Wednesday.

“I’m pleased to report we are raising our full year earnings-per-share growth forecast to at least 12% based on the continued strength of our international businesses,” Chief Executive David C. Novak said in the earnings release. “We delivered EPS growth of 13% in the second quarter as strong performance in China and other emerging markets, combined with the benefit of a lower tax rate, offset a very disappointing quarter in the U.S.”

Yum shares have risen nearly 40% over the past year, expanding faster than the S&P 500 or broad market. [Consumer ETFs Search Overseas for Profit.]
