Is Taco Bell About to Help Yum! Brands Deliver a Good Quarter?

Taco Bell has become the bellwether for Yum! Brands (NYSE: YUM), and there are signs it might help the restaurant operator post an earnings surprise yet again when it reports on Thursday.

Even though the Mexican-food chain is the smallest of Yum! Brands' restaurants in terms of number of locations, with only about of third of those for Pizza Hut and KFC, it generates the second-largest amount of revenues and the second-highest operating margins. It's also the only Yum! chain reporting sales growth so far this year.
