NEW YORK (TheStreet) -- Chipotle Mexican Grill (CMG) - Get Report stock closed up by 1.34% to $466.15 on Wednesday, as the Mexican food chain considers entering the burger chain market, Bloomberg reports.

The Denver-based company filed an application to trademark the "Better Burger" name for a burger-focused restaurant concept, a spokesman told Bloomberg.

"It's a growth seed idea we are exploring," the spokesman said, according to Bloomberg. "We have two non-Chipotle growth seeds open now -- ShopHouse and Pizzeria Locale -- and have noted before that the Chipotle model could be applied to a wide variety of foods."

Chipotle is seeking ways to expand beyond its core brand, which had several E. coli and norovirus outbreaks that have hurt sales and could cause a loss for the 2016 first quarter.

Separately, Chipotle has a "hold" rating and a letter grade of C+ at TheStreet Ratings because of the company's strengths, such as respectable return on equity, and its weaknesses, including generally disappointing stock performance, unimpressive growth in net income and poor profit margins.
