US stocks failed to make headway higher amid ongoing inflation, tariff and economic worries. Nvidia earnings and inflation data are due this week.

What happens with Nvidia matters for the entire U.S. stock market. The chip company has grown into the second-largest company on Wall Street, which means the stock’s movement carries more weight on the S&P 500 and other indexes than every company except Apple. The tech giant, based in Santa Clara, California, is now worth over $3 trillion.

Nvidia stock was slumping Tuesday following a report about harsher curbs on chip sales to China ahead of a make-or-break quarterly earnings report. Shares of the semiconductor maker has fallen 2.4% to $127.

U.S. equity futures moved higher in early Monday trading, helped by a pullback in the dollar and steady Treasury bond yields, as investors looked to claw back some of last week's sharp declines heading into a key week for tech stocks on Wall Street.
