U.S. stocks dropped on Friday, pulling benchmarks back into the red for the year, as the December jobs report topped expectations but hourly earnings declined, and investors tracked events in France after Wednesday's massacre at Charlie Hebdo magazine in Paris.
Market analysts generally downplayed the notion that Friday's declines had much to do with the labor report.
"It's been such a volatile week, people shouldn't read too much into one-day moves," David Kelly, chief market strategist at JPMorgan Funds, said, referring to a week that has so far had the Dow Jones Industrial Average finishing each day a triple-digit move in either direction.
Others pointed to overseas concerns as a factor.
"We think the market has caught up with the 'terrorism fear.' Since the beginning of the French ordeal the markets have ignored the event. We believe the escalation of the situation gave investors a reason to worry," Peter Cardillo, chief market economist at Rockwell Capital, wrote in an email.
"It was a really positive jobs report. I know the market sold off here in an aftermath reaction, but we just had an incredible rally, it's a Friday, we have the situation in Paris, we're setting up for the upcoming weekend and we have earnings starting next week," JJ Kinahan, chief strategist at TD Ameritrade, said of investor unease.
"And then there's the crude-oil situation, until you see three weeks of stability in crude, it's going to spell volatility in the market," Kinahan added of crude's seventh weekly drop.

Quickly erasing a 7-point opening gain, the Dow Jones Industrial Average dropped as much as 221 points, and ended down 170.50 points, or 1 percent, at 17,737.37, leaving it down 0.5 percent for the week.
