Dec 16 - Wall Street rose on Wednesday, with the Nasdaq hitting a record high as investors awaited a potential fiscal economic stimulus package and after the Federal Reserve repeated a pledge to keep its benchmark interest rate near zero.

The S&P 500 was on track to close at its highest level ever after the Fed promised to keep funneling cash into financial markets to fight the recession, even as policymakers' outlook for next year improved following initial rollout of a coronavirus vaccine.

"I don't think there's anything in there that changes their accommodative stance. ... The market's reaction is relatively subdued," said Randy Frederick, vice president of trading and derivatives for Charles Schwab.

Frederick said investors are more focused on fiscal stimulus than the Fed statement following its two-day meeting.

"The expectations for stimulus are built in, so if we don't get one that would be a much more substantially negative reaction that if we get one, which would be very modestly positive," he said.

Gains in tech stocks, many of which have benefited from changes in consumer habits because of the pandemic, pushed the Nasdaq to a record high. Microsoft surged almost 3%.
