Sept 9 (Reuters) - Early gains on Wall Street fizzled out by afternoon on Monday as losses in technology and healthcare stocks overshadowed increased expectations of stimulus from central banks around the world.
Microsoft Corp and Amgen Inc were among the biggest drags on the S&P 500 and Nasdaq.
Amgen fell 3.19% after analysts raised questions about data on the company’s lung cancer drug, dragging the healthcare sector down 0.94%.

“The markets are continuing last week’s positive sentiment but with a reduction in pessimism and fear,” said Scott Brown chief economist at Raymond James in St. Petersburg, Florida.
Stocks gained last week on easing U.S.-China trade negotiations and global political tensions as well as increased hopes of an interest rate cut.
Cementing those expectations, Fed Chairman Jerome Powell said late last week the central bank would “act as appropriate” to sustain economic expansion, a phrase that financial markets have read as a sign of an impending of rate cut.
Earlier on Monday, U.S. Treasury Secretary Steven Mnuchin said he did not see the threat of a recession as the Trump administration seeks to revive trade negotiations with China, adding that he expected a positive year ahead for the U.S. economy.
Energy stocks led gains among the 11 major S&P 500 sectors with a 1.41% rise, as oil prices got a boost from the new Saudi energy minister committing to output cuts.
