Context
OUR TAKE Given these circumstances, it is imperative for investors and analysts to keep a close eye on forthcoming economic indicators and corporate earnings reports. These insights will be crucial in determining whether this downturn represents merely a temporary correction or marks the onset of a prolonged period of market weakness. As we navigate the uncertain waters of September, it remains clear that the coming weeks could bring continued volatility, making it essential to remain vigilant and prepared for further market shifts. –Vicky Wu, BTW reporter Wall Street witnessed a significant downturn on Tuesday as major indices suffered their steepest single-day declines since early August. The S&P 500 tumbled more than 2%, while the tech-heavy Nasdaq Composite plummeted over 3%.

Analysis
The decline was driven by a weakening of investor confidence in artificial intelligence and unfavourable economic data. Among the hardest hit were chip stocks, with AI leader Nvidia experiencing a near 10% nosedive, contributing to an 8% slump in the PHLX chip index. This sell-off has heightened concerns among traders, especially as September is historically a challenging month for equity markets. According to Dow Jones Market Data, since 1928, the S&P 500 has averaged a monthly decline of 1.2%, with positive returns seen only 44.3% of the time during this month. Carol Schleif, chief investment officer of BMO family office said, “Sept / Oct are notoriously volatile months for markets, particularly in presidential election years. This year in particular, investors seem anecdotally even more concerned given the big swings in polls and rapidly see-sawing potential outcomes.” Also read: Nvidia shares drop 9.5%, leading record market value loss as AI optimism dims
