A123 Systems (AONE) -8.4% premarket after Goldman Sachs reduces its rating to Sell from Hold and cuts its price target to $2.50 from $5, citing “risk to transportation segment unit volumes and thus the potential for another capital raise in challenging market conditions." Shares spiked recently after AONE received a contract to supply battery systems for GM's new Spark electric car.
