U.S. stock indexes closed mostly higher Friday, though the S&P 500 posted its first weekly loss in four weeks.

The benchmark index eked out a 0.3 percent gain after another day of wobbly trading. The Dow Jones Industrial Average finished with a small loss. Gains in communication services, health care and other sectors outweighed a decline in technology and energy companies.

Treasury yields remained near their highest levels since June.

The indexes bounced between small gains and losses after a sluggish start as investors weighed another batch of corporate results from the summer earnings period. The up-and-down moves have been a familiar pattern recently as traders keep an eye on the ongoing negotiations between Republican and Democractic leaders in Washington over more economic aid for the pandemic-stricken economy.

“It’s generally been a little more of a selling market, and a lot of that has to do with waiting to see whether or not we get a fiscal stimulus package before the election,” said Sal Bruno, chief investment officer at IndexIQ. “The odds of that are getting lower and lower the closer we get to the election.”

The S&P 500 won 11.90 points to 3,465.39, it’s second straight gain. The Dow Jones Industrial Average dropped by 28.09 points, or 0.1 percent, at 28,335.57. The Nasdaq composite, which is heavily weighted with technology stocks, gained by 42.28 points, or 0.4 percent, at 11,548.28. The index had been down 0.6 percent.

Small company stocks continued to best the rest of the market. The Russell 2000 index rose 10.25 points, or 0.6 percent, at 1,640.50. The index ended the week with a 0.4 percent gain, while the major U.S. indexes fell.-AP
