The Standard & Poor's 500 Index rose to a new record overnight on expectations the Federal Reserve will maintain its massive stimulus programme amid signs the world's biggest economy is stumbling.
The S&P 500 gained 0.4 per cent to 1769.21 and the Dow Jones Industrial Average rose 0.6 per cent to 15668.05. In Europe, the FTSEurofirst 300 index was up 0.4 per cent.
As the Federal Open Market Committee began its two-day meeting, more economic data showed the US economy's pace is far from robust. Retail sales fell 0.1 per cent in September, driven by a drop in car sales, Commerce Department figures showed. Excluding autos, sales gained 0.4 per cent.
A separate Labor Department report showed the producer price index fell 0.1 per cent, led by food prices, while consumer confidence recorded its biggest decline in two years this month, based on the Conference Board index, which fell to 71.2 from 80.2 in September. Those reports followed figures this week showing weaker than expected factory production and sales of existing homes.
The US dollar strengthened to 98.17 yen and climbed to $1.3739 per euro on expectations the Fed will retain its US$85 billion a month of bond buying. The Dollar Index rose about 0.5 per cent to 79.634.
