The North Star 50 index surged over 6% in the afternoon. The commercial aerospace sector remained active, with Zaiseng Technology achieving a fourth consecutive trading limit, and over ten stocks, including Aerospace Power, hitting the daily limit. Conversely, the Fujian sector faced significant declines, with nearly ten stocks, including Haixin Food and Sanmu Group, hitting the daily limit. Overall, nearly 4,400 stocks in the Shanghai and Shenzhen markets were in the red, with a total transaction volume of 1.89 trillion yuan [1]. Hot Topics Aerospace - The aerospace sector saw significant gains, with Zaiseng Technology achieving a fourth consecutive limit up, and Sichuan Jinding hitting the limit for the third time. Aerospace Power and Goldwind Technology also reached the daily limit. The catalyst for this surge was Elon Musk's indication that SpaceX might conduct an IPO next year, aiming to raise over $30 billion (approximately 212.3 billion yuan) with a target valuation of $1.5 trillion (approximately 10.62 trillion yuan).
