The stock became the first A-share technology company to open above 3 trillion yuan in market value and topped the STAR Market ranking, while first-hour turnover exceeded 100 billion yuan.
ChangXin Technology set several A-share market records in its first hour of trading, opening with a total market value of about 3.31 trillion yuan. That made it the first A-share technology stock to debut with a market capitalization above 3 trillion yuan and the largest listed company on the STAR Market, overtaking SMIC. Trading activity was also unusually intense: first-hour turnover surpassed 100 billion yuan, making it the first A-share stock to break that threshold in a single day based on early trading, with full-day volume seen as likely to set another record. The debut underscores how large technology listings can quickly reshape benchmark rankings and liquidity across China’s domestic equity market.
