Nvidia's Record Buyback Fails to Lift Nasdaq as Stocks Fall 1%

U.S. stocks fell Monday morning, with the Nasdaq Composite dropping 1%, despite Nvidia announcing a record $150 billion buyback expansion, as investors reacted to President Trump rejecting Iran's peace offer and rising Treasury yields. The Dow fell 0.7% and the S&P 500 dropped 0.8%, with energy as the only gaining sector as Brent crude spiked above $108 before settling near $100. Nvidia rose 2.1% alone among chipmakers, while rivals like SK Hynix and AMD fell sharply amid concerns over rate hikes and OpenAI pausing back-end training. The 10-year Treasury yield hit 5.26%, its highest since 2002, pushing gold down nearly 4%. This week brings key data, including job openings, GDP, and September's jobs report, plus Micron's earnings and a U.S.-China tariff cut agreement on $60 billion of goods.
