Shares of Dupont rose 2.5% in premarket trading after the industrial materials maker raised its full-year forecast for a second time.

Still, Wall Street’s main indexes have slipped from record highs as investors booked profit amid lofty stock valuations and as concerns over slowing economic growth and rising cases of the Delta variant hit sentiment. A deepening regulatory crackdown in China has also sent jitters across the global technology sector. China’s Tencent Holdings Ltd slumped as much as 10% in Asia after a Chinese state media outlet branded online games as “spiritual opium”.

Dow e-minis rose 0.47%, S&P 500 e-minis added 0.37% and Nasdaq 100 e-minis gained 0.11%. Bond yields steadied after weaker-than-expected manufacturing data in the previous session sent them to their lowest since July 20.

Focus on Tuesday will be on factory orders for June, while later in the week, traders will turn to data on the U.S. services sector and the monthly jobs report for July.
