The latest adjustments to several key Shenzhen stock market indices, including the Shenzhen Component Index, ChiNext Index, and Shenzhen 100, officially took effect on December 15, 2025.

The Shenzhen Stock Exchange and Shenzhen Securities Information Co., Ltd. had previously announced that, in accordance with index compilation rules, periodic sample adjustments would be made to these indices.

The Shenzhen Component Index saw 17 constituent changes, with 10 companies from the main board and 7 from the ChiNext board being removed, including Sinopharm Group Co., Ltd. (000028.SZ), China Tianying Inc. (000035.SZ), and Tibet Mineral Development Co., Ltd. (000762.SZ). Seven main board and 10 ChiNext companies were added, such as Shenzhen Special Economic Zone Real Estate & Properties (Group) Co., Ltd. (000029.SZ) and Shenzhen Sunmoon Microelectronics Co., Ltd. (300548.SZ).

The ChiNext Index replaced 8 constituents, removing companies like Beijing Originwater Technology Co., Ltd. (300070.SZ) and adding new entrants such as Han's CNC Technology Co., Ltd. (301200.SZ).

The Shenzhen 100 Index underwent 7 constituent changes, with additions including Zangge Mining Co., Ltd. (000408.SZ) and Anker Innovations Technology Co., Ltd. (300866.SZ). The ChiNext 50 Index replaced 5 constituents, adding companies like Shenzhen Sunmoon Microelectronics Co., Ltd. (300548.SZ).

The adjustments reflect three core principles: promoting new quality productive forces, strengthening the foundation of the real economy, and guiding long-term value investment.

Post-adjustment, strategic emerging industries now account for 93% of the ChiNext Index's weighting, with constituent companies showing a 13% year-on-year increase in R&D spending. The Shenzhen 100 Index saw its strategic emerging industries weighting rise to 81%, while the ChiNext 50 Index reached 98% in this category.

In terms of economic fundamentals, manufacturing companies now represent 76% of the Shenzhen Component Index's weighting, making it the manufacturing sector's most representative benchmark in China's capital markets. The ChiNext Index constituents reported robust 16% revenue growth and 24% net profit growth year-on-year for the first three quarters.

Regarding investor returns, nearly 60% of the new Shenzhen Component Index constituents have implemented "dual improvement" action plans for quality and returns, while over 30% have launched share repurchase programs. Shenzhen 100 companies distributed RMB 302.2 billion in dividends this year, accounting for 55% of total Shenzhen market dividends.
