The Nasdaq Set a Record and the Dow Lost 270 Points on the Same Morning

The Dow and S&P 500 experienced a slight decline on Tuesday as oil prices remained stagnant near $100 a barrel, while the Nasdaq Composite achieved a record close, according to Reuters. The S&P 500 dropped 0.43 points, or 0.01%, to 7,764.27 points, whereas the Nasdaq Composite surged 121.15 points, or 0.45%, to 27,243.24. The Dow Jones Industrial Average experienced a 0.36% decrease, settling at 51,863.89.

Chip stocks continued to outperform, while consumer-focused software companies witnessed declines as investors evaluated the strong performance of Meta Platforms' new AI assistant, Muse. Launched earlier this month, Muse can send emails and execute transactions on behalf of users. Its early success boosted AI-related chip stocks, but it also raised concerns about the potential disruption of AI technology in various sectors like retailers, online brokerages, and consumer businesses.

Amazon briefly blocked Muse from conducting shopping on its platform on Monday. Market observers noted that a multitude of tech stocks experienced declines due to fears surrounding Muse's capabilities to manage insurance relationships, book travel, and search for purchases.

Uber Technologies and Lyft both experienced a drop of approximately 1%, while Expedia declined by 4% and Charles Schwab decreased by 5.5%. Stock prices of Micron and SanDisk increased by 3.9% and 7.2%, respectively.

Oil prices fluctuated around $100 a barrel, and the yield on the benchmark 10-year Treasury note hovered near 4.94% following US President Donald Trump's warning during a speech at the UN General Assembly that he would consider annihilating the Islamic Republic if a deal to resolve the Middle East conflict was not reached.

Investors also focused on Thursday's US-China summit, speculating that the trade truce with Beijing might be prolonged, and the talks could encompass AI regulation. Market experts expressed optimism that the talks may lead to the establishment of a global framework for AI regulation rather than a prolonged competition.

JPMorgan Chase and Wells Fargo both witnessed a decline in their stock prices. Meanwhile, Susan Collins, the Boston Federal Reserve President, supported the recent interest-rate increase due to inflation risks. John Williams, the New York Fed President, stated that the Federal Reserve's framework for managing short-term rates had effectively supported financial markets.

Traders estimated a 53% probability that the central bank would raise interest rates by at least 25 basis points in October, as per CME Group's FedWatch Tool.
