Data from Wind reveals that, to date, the A-share market has witnessed the addition of 374 new indices this year, with technology-themed indices emerging as the primary focus of these releases. The product lineup is strategically centered around four key sectors: robotics, semiconductors, artificial intelligence, and new energy systems, extending its reach to pivotal links within the industrial chain. Simultaneously, the trend toward sophistication is evident not only in the introduction of new indices but also in the revisions of rules governing existing flagship indices. Relevant institutions have bolstered the indices' market representation accuracy, risk management capabilities, and their guiding influence on new quality productive forces. This has been achieved through the implementation of mechanisms such as ESG negative screening, adjustments to sample sizes, and refinements in the sample selection processes.
