United States stock markets experienced their sharpest single-day selloff in over two years on the first trading day of September. The S&P 500 plummeted 4.2 percent to close at 5,247, while the Dow Jones Industrial Average fell 3.8 percent and the tech-heavy Nasdaq Composite dropped 5.1 percent. The broader market rout erased approximately 1.8 trillion dollars in market capitalization. Declining equities outnumbered advancers on the New York Stock Exchange by a ratio of twelve to one, reflecting widespread liquidation across all eleven S&P sectors. Technology giants, financial institutions, and consumer discretionary firms led the losses. The downturn was triggered by fresh economic data showing U.S. manufacturing activity contracted for the sixth consecutive month, with the Institute for Supply Management manufacturing index falling to 46.2 in August. The employment component dropped to 44.3, stoking recession fears and driving investors into safe-haven assets such as U.S. Treasury bonds and gold.
