The Sci-Tech Innovation 50 and other indices are about to undergo rebalancing!

On February 27, the Shanghai Stock Exchange and China Securities Index Co., Ltd. jointly announced that they have decided to adjust the sample stocks of the Sci-Tech Innovation 50 and other indices, effective after the market close on March 13, 2026.

Among them, Guodun Quantum, Zhongke Feice, and Zhongke Xingtu will be added to the Sci-Tech Innovation 50 Index. Rejing Biotech, Sirui New Materials, Junshi Biosciences, and other 10 securities will be added to the Sci-Tech Innovation 100 Index.

After this adjustment, on one hand, the Sci-Tech Innovation broad-based index further enhances its representation of the STAR Market. Post-adjustment, the Sci-Tech Innovation 50 Index has a total market capitalization of 4.5 trillion yuan, covering 39%. The Sci-Tech Innovation 100 Index has a total market capitalization of 2.7 trillion yuan, covering 24%. The combined coverage of the Sci-Tech Innovation 50 and 100 indices reaches 63%, an increase of 1.1% compared to before the rebalancing. On the other hand, the adjustment allows for an orderly exchange of sample stocks within the system: stocks added to the Sci-Tech Innovation 50 come from the Sci-Tech Innovation 100, while stocks removed from the Sci-Tech Innovation 50 are transferred to the Sci-Tech Innovation 100. This coordinated linkage jointly reflects the performance of large- and medium-cap securities on the STAR Market.

It is reported that the Sci-Tech Innovation 50 and 100 indices fully cover the six major industries of the STAR Market, with a diversified emerging industry structure. Notably, the weight of the new-generation information technology sector in the Sci-Tech Innovation 50 has increased by about 2%, while the weights of new materials, biomedicine, and other sectors in the Sci-Tech Innovation 100 have increased by about 4%.

In recent years, the Shanghai Stock Exchange has continuously improved the “One Body, Two Wings” index system, accelerating the enhancement of index quality and diversity, strengthening its ability to serve the development of new-quality productivity and high-level technological self-reliance, effectively supporting long-term funds entering the market.

Specifically, the existing indices undergo periodic rebalancing to eliminate underperformers, further improving index quality and their capacity to support national strategies. The industry structure of the SSE 50 and CSI 300 indices has been optimized, with weights of information technology and other “new economy” sectors increasing by 4.9% and 4.7% respectively compared to the end of 2024, reflecting the trend of modern industrial restructuring and better supporting high-quality development of new productivity. The newly launched indices feature diversified layouts: 33 STAR Market indices achieve full coverage of market value and industry chains, guiding over 320 billion yuan of funds into supporting the development of listed companies in the “hard technology” field through index-based investments. In 2025, the Sci-Tech Innovation Composite Index, representing the “panoramic view” of new-quality productivity, was launched to provide investors with a comprehensive and balanced tool for observing the overall operation of the STAR Market and investment targets. Since its release, it has gained 68%, making it one of the best-performing comprehensive indices in the domestic market, now ranking alongside the SSE Composite Index, Shenzhen Component Index, and ChiNext Index as one of the four core broad-based indices of A-shares.

Looking ahead, the Shanghai Stock Exchange will continue to enrich and optimize the index layout, providing investors with diversified channels for frontier technology allocation, and helping to share in the long-term dividends of new-quality productivity development.
