The tech-heavy Nasdaq composite index fell 6.85 points to 1,956.47, and the blue-chip Dow Jones industrial average rose 117.69 to 10,416.25.
Friday's lackluster tech performance follows a slight rally at the end of Thursday's session, as buyers bid the Dow into positive territory and the Nasdaq up from its session lows, but failed to drive it above 2,000.
A much-anticipated producer price index (PPI) gave investors a surprise; the Labor Department's report showed prices paid to U.S. producers fell in July at the fastest pace in eight years. The index, considered the main reader on inflation, tumbled 0.9 percent last month, mostly due to dropping energy prices. The core PPI, which excludes the volatile food and energy sectors, rose 0.2 percent in July after posting a 0.1 percent increase in the prior month.
Economists expected the PPI to fall 0.3 percent last month and the core rate to rise 0.1 percent.
"The PPI data provided a mixed picture for equities. They were down more than expected, mainly in the energy sector," Jack Regan, chief market strategist with Josephthal, told Reuters. But the core rate was higher than expected.
The news was mostly positive for investors, since it gives the Federal Reserve the go-ahead to cut interest rates again at the next meeting, scheduled for Aug. 21.
