Yes, but from the perspective of tradable shares, the mutual shareholding ratio between securities companies is not large, and the former 10 shareholders of securities companies are generally companies or funds, so they are rarely disclosed.

However, I finally found one. As of September 30th, 20 10, Everbright Securities Co., Ltd. held 6,564,400 shares of Huatai Securities, accounting for 0.84% of the total share capital of Huatai Securities. Everbright Securities is the fourth largest tradable shareholder of Huatai Securities.
