Hong Kong's Hang Seng Index down 1.18% at close, Hang Seng Tech Index down 0.74%

The Hang Seng Index and the Hang Seng Tech Index both experienced a decline on July 2, 2025. The Hang Seng Index closed down by 1.18%, while the Hang Seng Tech Index fell by 0.74%.

The market movements were influenced by several factors, including the semi-annual review results of the Hang Seng Composite Index, which were announced on August 22, 2025 [1]. Two companies, CaoCao Inc. and Mirxes, were added to the index, with the changes taking effect on September 8, 2025 [1][2].

CaoCao Inc., a shared mobility platform incubated by Geely, was added to the Hang Seng Composite Index due to its strong market position and growth potential. The company has seen significant growth in its Gross Transaction Value (GTV) and has introduced all-electric vehicle models specifically designed for shared mobility scenarios [1]. This addition is expected to broaden CaoCao Inc.'s investor base and attract additional capital from Mainland China.

Mirxes, a Singapore-headquartered biotech firm, was also added to the Hang Seng Composite Index. The company focuses on microRNA-based cancer detection and expects its inclusion in the index to increase its visibility and trading liquidity [2]. This addition may enable Mirxes to tap into a broader pool of investors, including those in mainland China through the Shanghai-Hong Kong Stock Connect and Shenzhen-Hong Kong Stock Connect schemes.

The inclusion of these companies in the Hang Seng Composite Index is likely to have an impact on the broader market, as passive funds tracking the index adjustment may carry out concentrated buying. This could contribute to noticeable volume growth and upward momentum in the share prices of the added companies.

However, the market's reaction to these index adjustments was mixed. While some investors welcomed the changes, others remained cautious due to broader market uncertainties and geopolitical risks. The overall market sentiment was neutral, with a slight bias towards caution.
