12:40 PM EDT, 08/28/2025 (MT Newswires) -- US equity indexes and government bond yields were mixed in midday trading on Thursday as investors weighed Nvidia's ( NVDA ) earnings and Federal Reserve Governor Lisa Cook's lawsuit to fight a move to oust her from the central bank's board.

The Dow Jones Industrial Average was little changed at 45,585.1, while the S&P 500 rose 0.2% to 6,492.5 and the Nasdaq Composite was 0.5% higher at 21,688.2. Healthcare led the decliners intraday, while the communication services sector was the top gainer.

In company news, Nvidia's ( NVDA ) shares rose 1.3% after the company reported Q2 results overnight.

While overall revenue rose year-over-year, Nvidia's ( NVDA ) data center compute products, such as its graphics processing units, declined 1% from the previous quarter, according to an AFP news report published in the Jakarta Post. The drop was driven by a $4 billion decrease in sales of H20 chips-specialized processors the company designed for the Chinese market, the AFP report said, citing Nvidia's ( NVDA ) earnings. For the current quarter, Nvidia ( NVDA ) projected $54 billion in revenue but said its forecast assumes no H20 sales.

Liz Claman of Fox Business wrote Thursday in a post on X that Nvidia ( NVDA ) Chief Executive Officer Jensen Huang has said that he is in talks with the Trump administration about selling the Blackwell artificial intelligence chips to China and his willingness to give the US government a cut of those sales, citing an interview with the CEO.

Meanwhile, Fed Governor Cook filed a lawsuit Thursday in federal court contesting President Donald Trump's attempt to oust her from the Board of Governors over allegations she lied on mortgage applications, Bloomberg reported, citing court records.

Treasury yields were mixed in midday trading, with the 10-year yield down 2.3 basis points to 4.22% while the two-year rate rose 1.6 basis points to 3.64%.

In economic news, gross domestic product was revised upward to a 3.3% jump in Q2 from a 3% gain in the advance estimate, above the 3.1% increase expected in a survey compiled by Bloomberg. GDP fell by 0.5% in Q1.
