(Sharecast News) - US stock markets opened mixed on Tuesday with the Dow in the red but the S&P 500 and Nasdaq snapping a three-day losing streak as Nvidia rebounded after recent falls.

As of 0952 EDT, the S&P 500 was rising 0.2% while the Nasdaq gained 0.6%. Both indices have been on the retreat since hitting fresh record highs on 18 June as investors took profits in Nvidia following the stock's eye-watering rise so far this year. Nvidia was up 3.2% in early deals after a 13% drop over the past three sessions.

"There are a few FOMC members speaking this afternoon, but otherwise the calendar is light. That suggests that NVIDIA will continue to pull the focus as analysts debate just how valuable the company could become, given its pole position in the future development of generative AI," said David Morrison, senior market analyst at Trade Nation.

The Dow Jones Industrial Average was 0.2% lower on the back of a drop in the price of heavyweight Boeing, after a Korean Air Boeing aircraft heading for Taiwan dropped 25,000 feet in five minutes following a fault with its pressurisation system.
