Wall Street kicked off September with a sharp sell-off, as surging bond yields, renewed trade uncertainty, and disappointing data from major tech firms like Nvidia and Amazon rattled investor confidence.
The Nasdaq Composite dropped 1.3% on Tuesday, erasing all of its August gains in a volatile return from the US Labour Day break. The S&P 500 fell 1% and the Dow Jones Industrial Average shed 0.8%. The sell-off was broad-based but particularly severe in the tech sector, which has been the engine of market gains throughout 2025.
