Separately, TheStreet Ratings team rates BUFFALO WILD WINGS INC as a Buy with a ratings score of B+. TheStreet Ratings Team has this to say about their recommendation:
"We rate BUFFALO WILD WINGS INC (BWLD) a BUY. This is driven by a few notable strengths, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its robust revenue growth, increase in net income, growth in earnings per share, solid stock price performance and largely solid financial position with reasonable debt levels by most measures. We feel its strengths outweigh the fact that the company shows low profit margins."
