On September 25, 2025, as the U.S. stock market commenced trading, the three major indices—the Nasdaq, the S&P 500, and the Dow Jones Industrial Average—all opened with a downward trajectory. The Nasdaq Composite Index dipped by around 0.9%, the S&P 500 Index experienced a 0.59% decline, and the Dow Jones Industrial Average registered a 0.25% drop.

Among individual stocks, Tesla witnessed a significant slide, with its share price plummeting by over 3%. This downturn was partly attributed to a notable year-on-year decrease of over 36% in new vehicle registrations in the European Union during August. Conversely, Intel saw a modest uptick of 1.5%. Reports surfaced indicating that Intel had approached Apple for potential investment opportunities. Additionally, Intel was planning to implement a price hike of over 10% for its 'Raptor Lake' processor in the fourth quarter.

Oracle, on the other hand, faced a sharp decline of over 4% as it embarked on a substantial $18 billion bond issuance. In contrast, IBM experienced a notable surge of over 2% following the launch of the world's first quantum-enabled algorithmic trading system, developed in collaboration with HSBC.
