When the fast-food giant behind KFC, Taco Bell and Pizza Hut reports quarterly earnings Tuesday after the close, Wall Street will be watching to see how the China factor could impact results.

Yum Brands, which has a massive presence in China, is still coping with a 2014 food scare and a challenging economy. Just this year, same-store sales have fallen by more than 10 percent versus a year ago.

"This is the first quarter that the company will report comps in China excluding the impact of the supplier incident," said Karen Short, Deutsche Bank research analyst Karen Short on Monday's "Fast Money. She believes overall profit in that region could return.

Short, who has a "hold" rating and a $90 price target on the stock, said the stock should move favorably on the results because expectations are reasonably low.

"We expect Taco Bell to perform extremely well. We expect KFC to be in-line and fairly positive. And we expect Pizza Hut to continue to struggle, " Short noted.

Shares of Yum Brands are down more than 9 percent in the past three months, but the company's shares have traded positive four out of the past five sessions.

The Street is forecasting Yum Brands will report earnings of $1.07 per share on $3.67 billion in revenue, according to FactSet.
