Review: The Sci-Tech Innovation 50 Index opened high and rose greatly, increasing by over 5%. 20cm, a semiconductor company, hit the daily limit up and reclaimed the throne of stock king.

The three major indexes of A-shares today have mixed performances. As of the close, the Shanghai Composite Index rose by 0.11%, the Shenzhen Component Index fell by 0.09%, the ChiNext Index fell by 0.27%, the SSE 50 Index fell by 0.12%, and the Science and Technology Innovation 50 Index rose by 5.19%. The total market turnover was 2.7592 trillion yuan, an increase of 150.3 billion yuan from the previous day, with over 2800 stocks rising in the entire market. In terms of sector themes, the energy and metal, semiconductor, football concept, copper cable high-speed connection, satellite navigation, military equipment, real estate, Hainan Free Trade Zone, PET copper foil, and education sectors performed well. On the other hand, the graphite electrode, gaming, steel, power, tourism and hotel, dye, gas, and battery sectors performed poorly. On the market, many semiconductor companies reported strong first-quarter results, boosting the domestic computing chip industry chain. Cambricon Technologies surged to the limit for the first time in 8 months, reaching a new historical high and reclaiming the title of "stock king." Stocks such as Montage Technology, CanSemi Technology, and Chipone Technology also surged. Recently, the price of lithium carbonate futures exceeded 180,000 yuan, continuing to strengthen the lithium mining sector, with Yanshan Lithium Industry seeing three consecutive limit-ups and Rongjie Shares seeing two consecutive limit-ups. The commercial aerospace sector was active, with many stocks like Shanghai Huagong and Runbei Aerospace hitting the limit. In addition, there was rotation among real estate, PET copper foil, and football concept stocks. On the other hand, the power sector fluctuated and fell back, with Jinko New Energy and Yueneng Holdings both hitting the limit down. The battery sector weakened in some areas, with HuaSheng Lithium Battery falling by 10%, as the net profit in the first quarter decreased compared to the previous quarter, with gross profit margins also falling, triggering selling pressure due to profit-taking.
