Nasdaq ends lower as Nvidia drags the tech sector for second day

The S&P 500 and Nasdaq closed marginally lower on Friday, weighed down by a decline in Nvidia shares for a second straight day, which dragged down the technology sector.

Technology was the biggest loser among the 11 major S&P 500 sectors, weighed by Nvidia, while communication services led the gain.

"It's Nvidia's game, and the rest of us are just pretending to be here," said Michael Green, chief strategist at Simplify Asset Management in Philadelphia.

"Basically all the activity is now concentrated in Nvidia call options," he added. "Seven million option contracts Nvidia have traded. That's something in the neighborhood of three or four times the quantity of contract volume that would have traded for the market in total five years ago."

According to preliminary data, the S&P 500 lost 5.52 points, or 0.10%, to end at 5,467.65 points, while the Nasdaq Composite lost 28.37 points, or 0.16%, to 17,693.22. The Dow Jones Industrial Average rose 27.48 points, or 0.07%, to 39,162.24.

Shares of megacaps Microsoft, Alphabet, Amazon.com and Apple rose.

"We've had a very strong run, especially in the S&P over the last couple weeks. So not surprised to see things kind of take a pause and settle down," Zachary Hill, head of portfolio management at Horizon Investments in Charlotte, North Carolina.
