On September 19, 2025, the three principal U.S. stock indices commenced trading with a slight upward tilt. The Nasdaq Composite Index climbed 0.37%, the S&P 500 Index advanced 0.23%, and the Dow Jones Industrial Average rose 0.15%. WeRide's stock price experienced a remarkable surge of over 3% after its autonomous minibus successfully obtained an L4 autonomous driving license in Belgium. This achievement marks a significant milestone for the company in the realm of autonomous vehicle technology.

In the same trading session, shares of both Apple and Tesla also witnessed an uptick, each rising by more than 1%. This positive movement could be attributed to a variety of factors, including favorable market sentiment and potential product announcements or financial results.

Conversely, stocks associated with the quantum computing sector exhibited a lackluster performance. Notably, IONQ, QUBT, and RGT all commenced trading at lower prices, reflecting a bearish trend within this niche market segment. This downturn might be linked to concerns over the commercial viability and long-term prospects of quantum computing technologies.
