2 of Wednesday's Big Stock Winners Could Have Further to Rise

Wednesday brought more volatility to Wall Street, as substantial early gains for the Dow Jones Industrial Average (DJINDICES: ^DJI), S&P 500 (SNPINDEX: ^GSPC), and Nasdaq Composite (NASDAQINDEX: ^IXIC) gave way to worries after Federal Reserve Chair Jerome Powell and the Federal Open Market Committee made their latest pronouncement on interest rates. Although the central bank didn't make any immediate moves, Powell said in no uncertain terms that investors needed to be prepared for a rate hike in March. Corning (NYSE: GLW) announced earnings results that gave investors something to smile about, while Groupon (NASDAQ: GRPN) rose on reports concerning one of its investments.
