Today's Market Winners and Losers (6/27/2012)

The market is slightly up slightly following news that U.S. home sales jumped 5.9% in May, reaching a 2-year high.  There weren’t as many big winners and losers for Wednesday’s list. On today’s winners and loser, we once again have a pharmaceutical company likely to receive patent approval for a drug. Meanwhile, earnings estimates changed the fate of two companies, one for better and one for worse.
