12:30 PM EDT, 08/04/2025 (MT Newswires) -- US equity indexes rebounded in a broad-based rally in midday trading on Monday amid declines in both government bond yields and volatility.

The Nasdaq Composite jumped 1.7% to 21,009.7 in midday trading on Monday, with the S&P 500 up 1.3% to 6,318.5 and the Dow Jones Industrial Average 1.1% higher at 44,069.2, rebounding from the dive on Friday. All sectors except energy rose intraday, with technology and communication services leading the gainers.

Most US Treasury yields declined, with the 10-year yield down 1.6 basis points to 4.2% and the two-year rate fell 1.2 basis points to 3.7%.

The CBOE Volatility Index sank 11% to 18.08, after trading above 20 in the sharp sell-off on Friday following an ultra-weak non-farm payrolls report.

In economic news, new orders for US factory goods fell by 4.8% in June, as expected in a Bloomberg-compiled survey and following a revised 8.3% increase in May. Excluding a 22.4% decline in transportation orders, new orders would have been up 0.4% after a 0.3% gain in May, compared with expectations for a 0.2% gain.

In company news, IDEXX Laboratories ( IDXX ) shares soared 27% intraday, the top gainer on the S&P 500 and the Nasdaq, after the company posted stronger-than-expected Q2 earnings and revenue, and boosted its 2025 guidance.

Onsemi (ON) shares slumped 11% intraday, the worst performer on the S&P 500 and the Nasdaq, after the company reported lower fiscal Q2 non-GAAP earnings and sales.
