Buffalo Wild Wings  (BWLD) shares were  slightly higher Friday morning after analysts at Maxim Group upgraded the company's stock to "buy" from "hold" while also raising its price target to $180 from $175. 

The firm made a valuation call on the company, noting that the stock has fallen significantly from its all time high above $200 less than two years ago. Given that pullback, caused by slowing sales and a high-profile campaign by activist firm Marcato Capital, the firm believes that the stock's upside is very attractive. 

Buffalo Wild Wings stock has fallen more than 4% this week, and currently traded at $154.50.
