As a result of a Piper Jaffray Cos. Buy recommendation on Yahoo! Inc. (NASDAQ:YHOO), the company’s stock gained 1.9%.

Analysts Gene Munster and Douglas Clinton said in a note that though their firm view’s the once-formidable internet company’s core business to be challenged, it’s stake in Alibaba will likely make up for this deficiency. Piper Jaffray also indicated a price target of $43 on Yahoo! Inc. (NASDAQ:YHOO) stock, up $6 from $37.
