There were a few other interesting stocks that were hit with upgrades and downgrades that I thought I would look in on. Today's highlights include Lululemon Athletica (LULU), Best Buy (BBY), Buffalo Wild Wings (BWLD), and Akeena Solar (AKNS).

• Lululemon Athletica (LULU) was upgraded from "market weight" to "overweight" at Thomas Weisel this morning. Prior to today's upgrade, Zacks reported that LULU had 2 "strong buy" rating and 5 "hold." The shares are up more than 3% today after falling 2.4% on Wednesday. The shares were once again rejected by the 34 level, which stopped the stock's rally on March 27.

• Best Buy (BBY) was cut to "sector perform" at Pacific Crest this morning. As a result, the shares of Best Buy have dropped more than 3%, giving up most of the gains they had racked up during the past couple of trading days. The shares are currently perched on support at their 10-day moving average. BBY isn't particularly well-liked on Wall Street, as Zacks reports that the stock has earned 6 "strong buy" ratings, 8 "holds," and 2 "strong sells."
• Buffalo Wild Wings (BWLD) picked up some fresh coverage today, though the analyst isn't too enthusiastic. Jefferies started Buffalo Wild Wings with a "hold" rating, adding to the bevy of "holds" the stock already has. Zacks reports BWLD has 3 "buy" ratings, 8 "holds," and 1 "strong sell." The security has bounced back from its session low of $25.84 and is currently up 0.68%. The shares are resting just above support at their rising 10-day trendline, which has helped to buoy the equity since March 18.
• Coverage of Akeena Solar (AKNS) was started today at Needham with a "hold" rating. Like most of the solar sector, the shares have edged higher during the past several sessions and are up 0.48% this afternoon. Coverage of the company is extremely light, as Zacks reports that the stock has earned 1 rating a "hold."
