Momenta Pharmaceuticals (MNTA -3.7%) slides after reporting a wider than expected Q1 loss this morning. The company attributes the miss to the January 2012 launch of a competitor's generic Lovenox, causing decreased unit sales and lower market share, which in turn led to lower prices in response to competitor pricing reductions.
