Still, analysts expect quarterly earnings to decline 2.9%.CVS Health Corp surged 4.7% on its $9.5 billion cash buyout offer for Oak Street Health Inc. Oak Street Health rose 4.5%.Declining issues outnumbered advancers for a 2.41-to-1 ratio on the NYSE and for a 2.42-to-1 ratio on the Nasdaq.The S&P index recorded nine new 52-week highs and two new lows, while the Nasdaq recorded 63 new highs and 27 new lows.
