S&P 500 ticks up on M&A; Nasdaq extends winning streak
The Nasdaq Composite rose for an eighth straight session, a streak not seen since early July.
The Dow Jones industrial average fell 23.99 points or 0.15 percent, to end at 16,130.40. The S&P 500 gained 2.13 points or 0.12 percent, to finish at 1,840.76. The Nasdaq Composite added 28.758 points or 0.68 percent, to close at 4,272.783.
Stock markets around the world edged higher following a fresh round of stimulus from the Bank of Japan, though gains were limited by some tepid data following a recent rally.
The Bank of Japan maintained its expansionary monetary policy, extending special loan programs to help buoy economic growth. Japanese shares jumped 3.1 percent, but other markets in Asia were flat after China's central bank acted to rein in lending and Australia's central bank made hawkish comments about interest rates.
Europe's top shares inched higher, weighed down by retailers, as analysts bet the rally that followed the emerging-market slump has now run out of steam.
The euro zone's blue-chip Euro STOXX 50 was up 0.04 percent, to 3,120.27 points, consolidating further after a slight drop in the previous session.
The pan-European FTSEurofirst 300 was up 0.04 percent, to 1,337.55 points.
