Merger news moved stocks last week

Merger news moved stocks last week. An agreement between US BioEnergy Corp. and VeraSun Energy, the third-largest ethanol producer, sent the stock of US BioEnergy up the most. Bidder VeraSun also got a boost, rising 3 percent Thursday and 7.7 percent Friday. MGI Pharma announced Thursday that it would seek strategic alternatives, and hired Lehman Brothers Holdings Inc. to explore a possible sale. Analyst downgrades on Arctic Cat Inc. put a chill on their stock, making it the biggest loser among mid-caps.
