The stock market was flat on Thursday ahead of a key House vote on the Republicans’ healthcare bill, which was delayed until Friday as GOP lawmakers failed to gather enough votes to proceed. The Dow Jones Industrial Average lost just 5 points, or 0.02%, while other broader market indexes saw similar small declines. But several individual stocks delivered outsized positive returns today, including FireEye (NASDAQ: FEYE), Penn National Gaming (NASDAQ: PENN), and SUPERVALU Inc. (NYSE: SVU).
