NEW YORK - The major US stock indices finished slightly lower Friday as a post-election rally appeared to lose steam.

The Dow Jones Industrial Average, Nasdaq and S&P 500 all finished 0.2 percent lower but they were still up over the prior week. The blue-chip Dow, which hit successive records since President-elect Donald Trump’s surprise victory last week, ended the week at 18,867.93.

The broader S&P 500 finished at 2,181.90 and the tech-heavy Nasdaq closed at 5,321.51. Peter Cardillo of First Standard Financial said stocks could be suffering in part due recent events on the exchange and bond markets. “I do not expect a major pull back but the Trump rally might be fading due to the strong dollar and higher yields,” he said. The Dow was dragged down in part by declining prices for pharmaceuticals. Merck fell 1.3 percent, Pfizer gave up 0.8 percent and Johnson & Johnson lost 0.4 percent. Insurance giant UnitedHealth Group also lost 0.9 percent. While tech stocks rose sharply earlier in the week, they retreated on the final trading day of the week.

 

 Google parent Alphabet sank 1.3 percent, Facebook lost 0.7 percent and the biotech company Amgen was down 1.4 percent.
