Most US stock indexes declined on Tuesday (except for the Dow Jones), as investors awaited more quarterly earnings results and monitored developments in trade negotiations between the United States and its partners, ahead of the reciprocal tariffs set to take effect in early August.

Commerce Secretary Howard Lutnick confirmed that August 1 is a firm deadline for the start of tariff implementation, though he noted that dialogue with countries could still continue beyond that date.

Investors are closely watching Q2 earnings reports. So far, 88 companies within the SP 500 have reported their results, with 82% of them surpassing analysts expectations, according to FactSet data.

Later this week, several major US tech firms are scheduled to report their results, with Alphabet and Tesla both set to announce on Wednesday.

As of 16:22 GMT, the Dow Jones Industrial Average rose 0.1% (42 points) to 44,365 points. The broader SP 500 fell 0.1% (8 points) to 6,297 points, while the Nasdaq Composite dropped 0.5% (102 points) to 20,872 points.
