Wall Street ends higher as tech rebounds before Nvidia results

Wall Street indexes finished higher on Tuesday as technology stocks rebounded before Nvidia's upcoming earnings report. Investors also found some relief from falling oil prices and lower bond yields, which had previously caused concern following a recent bond market rout. The gains may help set the tone for September, a typically weaker month for stocks.

Experts remain cautiously optimistic about the U.S. economy's outlook, with longer-dated Treasury yields falling and traders weighing the implications of Treasury Secretary Scott Bessent's decision to expand Treasury buybacks. Nvidia's results on Wednesday will be a key test for the earnings-driven rally, as any signs of slowing growth could reignite concerns about stretched valuations in the AI boom.

Other tech stocks, including Meta, Micron, and AMD, also saw gains, while retailers like Dick's Sporting Goods and Nike faced declines due to financial missteps. The upcoming Personal Consumption Expenditures report and Fed Chair Kevin Warsh's Jackson Hole speech on Friday will provide further insights into the Federal Reserve's monetary policy stance.
