Changxin Technology, a China domestic memory leader, debuted on the Sci‑Tech
Innovation Board and within its first hour set several A‑share records: it
became the first A‑share tech stock to open with a market value above 3 tln yuan
(opening market cap ~3.31 tln yuan); it topped the STAR Market market‑cap
rankings, surpassing SMIC; first‑hour turnover exceeded 100 bln yuan, making it
the first A‑share single‑stock listing day to breach 100 bln yuan turnover, with
full‑day volume likely to set a new record; and it is the first new listing to
combine >100 bln yuan turnover with a turnover rate above 50%, signaling
unusually high liquidity and trading activity.
