(Reuters) - The benchmark S&P 500 opened lower for the first time in 2018 on Monday, as losses in healthcare and financial stocks cut short Wall Street’s strongest start to a year in a decade.
The S&P and the Nasdaq last week recorded its strongest first four trading days in a year since 2006, and the Dow industrials posted its best since 2003.
“We had a strong market in the past week, and what generally happens in the first week sets the trend for the remainder of the year. Now that it’s established, there could be some profit- taking,” said Peter Cardillo, chief market economist at First Standard Financial in New York.
The Dow and the Nasdaq still eked out record highs briefly after open.
The dollar inched higher against a basket of major peers .DXY with data showing that slower U.S. jobs growth did little to dent expectations for further interest rate increases this year.
Comments by some Federal Reserve officials on Friday and over the weekend suggested the U.S. central bank remained on track to raise interest rates in 2018.
“The dollar is reversing and we’re seeing that effect due to some Fed comments,” Cardillo said.
A stronger dollar tends to weaken revenue of U.S. companies that earn much of its income from abroad.

The S&P healthcare index .SPXHC fell 0.5 percent and was the biggest decliner among major S&P sectors, led by 1.6 percent drop in AbbVie’s shares (ABBV.N) and a 1 percent fall in UnitedHealth’s (UNH.N).
