Pfizer's shares rebounded on the failed bid, making it thesecond-largest contributor to a rise in the S&P 500 index afterApple (NasdaqGS: AAPL - news) . Pfizer rose 1.27 percent to $29.49 a share, whileAstraZeneca fell 10.8 percent to 43 pounds in London.
Treasuries, meanwhile, rallied. Yields on the benchmark10-year U.S. Treasury note fell to 2.50 percent, lows last seenin October.
Analysts had expected interest rates to rise, but with ratestouching seven-month lows, the bond rally has helped U.S. stocksfrom falling further.
"It's easy to see why the market is very, very quiet, exceptthe big story is the bond market, that is the one thing thatstands out like a sore thumb," said Stephen Massocca, managingdirector at Wedbush Equity Management LLC in San Francisco.
Tim Ghriskey, chief investment officer of Solaris Group inBedford Hills, New York, said equity investors still see animproving U.S. economy yet the bond market sees otherwise.
"You really have this dichotomy going in and nobody iswinning and we are stuck in neutral a bit because of that,"Ghriskey said.
The pan-European FTSEurofirst 300 index, which lastweek hit a 6-year high of 1,372.81 points, was down 0.17 percentat 1,359.22 points.
U.S. Treasuries prices edged higher on sentiment that bondyields could hit multi-month lows again, leading investors tomainly seek longer-dated bonds to avoid price losses.
"When we get this dropping of yield, the folks that have notparticipated have really lagged from a performance perspective,"said Justin Hoogendoorn, fixed income strategist at BMO CapitalMarkets in Chicago. "You don't want to be caught off-side."
