Feb 1 (Reuters) - The S&P 500 held near an eight-week high on Friday as stronger-than-expected U.S. job growth in January allayed concerns about a slowdown, although disappointing outlook from e-commerce giant Amazon capped gains.
The Labor Department data showed nonfarm payrolls jumped by 304,000 jobs last month, the largest gain since February 2018, handily beating an estimated rise of 165,000, according to economists polled by Reuters.
The report also showed no "discernible" impact on job growth from a 35-day partial government shutdown. However, the longest shutdown in history, which ended a week ago, pushed up the unemployment rate to a seven-month high of 4 percent.
The data came two days after the Federal Reserve signaled that its three-year interest rate hike campaign might be ending because of rising headwinds to the economy.
"The payroll number was significantly stronger than what was expected, so a lot more people are finding jobs," said Randy Frederick, vice president of trading and derivatives for Charles Schwab in Austin, Texas.
"There is a huge concern about the growth rates in China and this certainly eases some amount of concern domestically."
Data from China showed that the manufacturing sector shrank for the second straight month in January, pointing to further strains on the economy that could heighten risks for global growth.
January ended on a high-note for U.S. markets, with the S&P 500 posting its best month since 2015, boosted by the Fed's dovish remarks and as hopes of a U.S.-China trade deal improved.
President Donald Trump said he would meet Chinese President Xi Jinping soon to try and seal a comprehensive trade deal.
