The S&P 500 slumped on Tuesday to kick off the first trading day of a holiday-shortened week, weighed by a jump in crude oil prices. The S&P 500 dipped 0.15%, while the Nasdaq Composite hovered near the flatline. Oil prices rose after Saudi Arabia extended its 1-million-barrels per day voluntary oil production cuts. "If you have oil prices moving up that could be inflationary," said Keith Lerner, co-chief investment officer at Truist. Meanwhile, the Dow and the Nasdaq are coming off their best weekly performances since July, while the S&P 500 registered its best week since June.
