Sept 23 (Reuters) - U.S. stocks jumped more than 1% on Thursday as investors appeared relieved about the Federal Reserve's stance on tapering stimulus and raising interest rates.

Upbeat outlooks from Accenture (ACN.N) and Salesforce (CRM.N) helped to bolster the market, while the U.S. Food and Drug Administration late Wednesday authorized a booster dose of the Pfizer-BioNTech (PFE.N) , COVID-19 vaccine for those 65 and older. read more

Also helping sentiment, concern about contagion from China Evergrande (3333.HK) continued to ease.

The Fed said on Wednesday it could begin reducing its monthly bond purchases by as soon as November, and that interest rates could rise quicker than expected by next year. The November deadline was largely priced in by markets.

In a press conference after the statement, Fed Chair Jerome Powell said the bar for lifting rates from zero is much higher than for tapering. read more

"This is a follow-on rally from a very good Fed meeting," said Tim Ghriskey, chief investment strategist at Inverness Counsel in New York.

"To me that showed there were no surprises and things were as expected," he said. "Any Fed rate hike is still quite a ways off and so much can change between now and then."
