Fewer than 100 stocks hit new highs Wednesday, and many of them ended lower as the market sold off. Packaged food stocks were the best performers after Kraft Foods (KRFT) said that it would merge with ketchup giant H.J. Heinz, creating one of the world’s largest food companies. Kraft gapped up and soared 21.84 — 36% — to 83.17, clearing a 67.84 flat-base buy point.
