U.S. nonfarm payrolls rose in December, topping Wall Street expectations, but wages unexpectedly fell.
"There was this tale of two cities, with very strong job gains but on the flip side a continued real moderation in wage growth. I think the market looked at that and was sort of confused about what that means," said Burt White, chief investment officer for LPL Financial in Boston.
"I actually think it's the best-case scenario. It showcases the U.S. economy is continuing to grow and repair the labor market, but at the same time, the muted wage growth means the Fed's going to stay lower for longer."
