New York stock exchanges closed Thursday with significant losses, driven by a sharp decline in Tesla shares and broader market anxieties. The Dow Jones experienced a percentage drop, while the Nasdaq Composite fell by 2.2 percent, nearing its largest daily decrease in over a month. The S&P 500 index also declined, losing 1.2 percent. European markets mirrored the trend, with the AEX index closing down 1.3 percent. Tech stocks, including Besi, suffered considerable losses following disappointing results from STMicroelectronics. However, Intel provided a late-day boost to investor sentiment with positive after-hours trading, offering a small counterpoint to the overall negative market momentum.
