Wall Street's main stock indexes closed higher on Tuesday, lifted by a renewed surge in artificial intelligence momentum and falling oil prices as investors prepared for a crucial Federal Reserve policy decision and upcoming corporate earnings.

During the session, the Dow Jones Industrial Average edged up 60.34 points, or 0.12%, to reach 52,423.99. The S&P 500 added 51.97 points, or 0.68%, to hit 7,728.74, while the tech-heavy Nasdaq Composite also advanced as chip stocks rebounded for a second consecutive day.

Market sentiment found additional support from declining oil prices, as Brent crude slipped for the second straight session. Meanwhile, investors kept a close watch on macroeconomic conditions, upcoming midterm elections, and the Federal Reserve, which is widely anticipated to hold interest rates steady following a rate increase the previous month.
