China's securities regulator said more than 90% of companies listed in recent years on mainland exchanges were technology-related, lifting the sector's share of market capitalization to over one-quarter - larger than the combined weight of financial and real estate stocks.

Wu Qing, chairman of the China Securities Regulatory Commission, said 24 of the 50 most valuable listed firms are now tech companies, up from 18 at the end of 2020. He was speaking at a State Council press briefing on financial sector achievements under the 14th Five-Year Plan (2021–2025).

Foreign investors hold 3.4 trillion yuan (about US$478 billion) in A-shares, while 269 Chinese companies remain listed overseas. As of end-August, long-term institutional investors - including pension funds, insurers and mutual funds - held 21.4 trillion yuan (about US$3 trillion) in tradable A-shares, up 32% from the end of 2020.

Wu added that regulators had stepped up risk monitoring and coordinated with state-backed investors to stabilize markets, measures he said helped restore confidence amid external pressures.
