US Stocks Close Lower: Chip Stocks Face Selling Pressure, Philadelphia Semiconductor Index Drops Over 6%, TSMC ADR Plummets Nearly 7%

US stock markets experienced a significant sell-off in chip-related shares on Wednesday, dragging down major indices. The Philadelphia Semiconductor Index suffered a sharp decline of over 6%, while the Taiwan Semiconductor Manufacturing Company (TSMC) ADR plummeted by nearly 7%.

This downturn in the semiconductor sector is largely seen as a profit-taking move by investors. Semiconductor stocks had surged by more than 80% in the first half of the year, leading to a correction as traders cashed in on their gains. Companies like Micron and SanDisk saw double-digit percentage drops, while Nvidia and Intel also experienced notable losses.

Despite the weakness in chip stocks, some large technology companies posted gains. Meta's stock rose nearly 9% following its announcement of a new cloud computing business and plans to sell idle computing power. Microsoft and Apple also saw increases of 3% and 1.7%, respectively.

Market sentiment was also influenced by upcoming economic data and statements from Federal Reserve officials. Investors are awaiting a key monthly employment report, while Fed Chair Jerome Powell reiterated the central bank's commitment to controlling inflation, suggesting that expectations for looser monetary policy might be disappointed.

The Fed will stay the course on its commitment to bring down inflation and will keep interest rates higher for longer to achieve its 2% inflation target, disappointing those who expect a pivot to looser monetary policy.
