U.S. stocks opened with mixed performances on Thursday. The S&P 500 index opened lower at 7,519.82 points, down 0.01%; the Dow Jones Industrial Average opened slightly higher at 50,660.98 points; the NASDAQ Composite index opened higher at 26,686.53 points, up 0.04%.

In individual stocks, Snowflake was the biggest focus of the day. The company announced a $6 billion procurement agreement with Amazon Web Services (AWS), which propelled the stock to a one-day increase of up to 35%, the largest single-day rise since 2024. The scale of this agreement demonstrates that the competitive landscape of the cloud data platform track is accelerating its reshaping.

Chinese concept stocks showed a clear divergence in performance. Li Auto declined by about 2%, with first-quarter revenue and second-quarter performance guidance both below market expectations, dragging down sentiment. Xiaopeng Group rose against the trend by about 1%, despite a net loss of 1.78 billion yuan in the first quarter, the second-quarter delivery guidance exceeded expectations, boosting market confidence. Futu Holdings also rose by about 1%, however, the company's net profit in the first quarter fell sharply by 61.2% year-on-year to 831 million HKD, and the fundamental pressure cannot be ignored.

At the industry level, the Internet stock index ETF rose by more than 1%, and the energy industry ETF rose by nearly 1%, performing at the forefront; the Global Airline Industry ETF fell by more than 1%, becoming one of the weakest sectors at the opening.

The potential focus for the follow-up lies in whether the agreement between Snowflake and AWS can continue to drive the sentiment of the cloud computing sector, as well as the chain reaction of Li Auto's guidance on the performance of the Chinese concept new energy vehicle sector.
