Yelp leaping; Sears spins off Lands End; Questcor boosting biotech


Making the list today as measured by your Yahoo Finance Ticker searches are:

Yelp (YELP): shares of the crowd sourced reviews site are up nearly 2% today after Oppenheimer upgraded the stock to "outperform" from "perform." (VO) Oppenheimer also set a price target of $78 for the stock. After tech high fliers got beaten down last week, Yelp may be the first in a line of buying opportunities in the sector.

Sears (SHLD): hares look to be down more than 17% in the first half of the trading day but it's not quite as bad as it looks. The retailer completed the spin off of its popular Lands End (LE) brand Friday evening and data feed errors are responsible for the scary number. According Yahoo Finance partner CNBC, Sears shares are actually up close to 2% on the news.

Questcor Pharmaceuticals (QCOR): just one of several pharma names popping today, Questcor is up more than 15% after it agreed to be bought for $5.2 billion by Irish drugmaker Mallinckrodt. At the center of the deal is Questcor's popular Acthar Gel, used to treat multiple sclerosis. The big move in the stock helps buoy a biotech sector that has had a really rough month.
