(Sharecast News) - Wall Street stocks turned in a mixed performance on Monday as Q3 earnings season gets set to pick up steam.

At the close, the Dow Jones Industrial Average was down 0.80% at 42,931.60, while the S&P 500 lost 0.18% to 5,853.98 and the Nasdaq Composite saw out the session 0.27% firmer at 18,540.00.

The Dow closed 344.31 points lower on Monday, snapping a three-day winning streak and knocking the blue-chip index off its all-time high.

Although market participants seemingly remain optimistic that US stocks can continue to deliver a solid performance, investors were also dialled in on heightened tensions in the Middle East and the upcoming US general election.

No major corporate earnings were released on Monday, but Tesla, Coca-Cola, Boeing, T-Mobile, and IBM will all report their latest quarterly numbers before the end of the week.

On the macro front, the Conference Board said on Monday that its leading economic indicators fell by more than expected in September, down 0.5% month-on-month after August's revised 0.3% drop.

Also in focus, the yield on the benchmark 10-year Treasury note rose almost 12 basis points to 4.19%, while the two-year note was up more than seven basis points at 4.036%.
