Shanghai Securities News · www.cnstock.com (Reporter Qi Doudou) - On August 29, the reporter learned from the Shanghai Stock Exchange (SSE) and China Securities Index Co., Ltd. that in accordance with the index compilation rules, the samples of the SSE STAR Market indices such as the SSE TAR 50 Index (STAR 50) will undergo regular quarterly adjustments, with this adjustment to be implemented after the market close on September 12.

STAR 50, STAR 100, and STAR 200 represent the performance of large-, medium-, and small-cap securities on the SSE STAR Market respectively, and the three indices together form the SSE STAR Market Size Index Series. Since the beginning of this year, relying on technological breakthroughs and the support of the SSE STAR Market’s “1+6” policy, the SSE STAR Market has attracted accelerated inflows of market funds into the “blue ocean” of “hard technology”. The STAR Market Composite Index, STAR 50, STAR 100, and STAR 200 have risen by 43.3%, 35.6%, 46.8%, and 54.9% respectively, all reaching new highs since September 24 last year.

Shengyi Electronics will be added to the STAR 50, and 5 securities including EFORT and Bluetrum will be added to the STAR 100. After this sample adjustment, on the one hand, the representativeness of the broad-based SSE STAR Market indices to the SSE STAR Market will be further enhanced. After the adjustment, the total market value of the STAR 50 stands at RMB 3.1 trillion, with a coverage rate of 38.9%; the total market value of the STAR 100 is RMB 1.9 trillion, with a coverage rate of 24.4%. The combined total market value coverage rate of STAR 50, STAR 100, and STAR 200 reaches 84.6%, an increase of 0.5% compared with that before the sample adjustment, which well represents the performance of large-, medium-, and small-cap securities on the SSE STAR Market. On the other hand, the top five constituent stocks of the STAR 50 and STAR 100 Indices remain basically unchanged. The number of adjustments has not reached the proportional limit for several consecutive quarters, indicating that the market value structure of the SSE STAR Market securities is relatively stable. Before and after the sample adjustment, the combined weight of the top five weight stocks in STAR 50 is 39.1%, and that in STAR 100 is 13.9%. The new generation of information technology, biomedicine, and high-end equipment are all among the top three industries.

Since the release of the Eight Measures for the SSE STAR Market, the SSE STAR Market indices have been continuously enriched, and the quality of index samples has been constantly improved. The reform of the SSE STAR Market has evolved from a “pilot field” to a “demonstration field” for high-quality development. Since the release of the Eight Measures for the SSE STAR Market, 16 indices including the STAR 200 and the STAR Market Composite Index have been launched one after another. At present, the number of the SSE STAR Market indices has reached 32, forming a SSE STAR Market index system covering the entire market value and industrial chain, represented by the SSE STAR Market Composite Index and STAR 50. This system provides diversified investment options for medium- and long-term funds. Currently, the total scale of the SSE STAR Market index products has exceeded RMB 320 billion, and the scale of the flagship index product (STAR 50) has exceeded RMB 190 billion, making it the fifth-largest broad-based index product in China and the largest single-market ETF product.

In the next step, with the implementation of the “1+6” policy measures for the SSE STAR Market, index-based investment will further play a positive role in better supporting high-level technological self-reliance and self-strengthening as well as the development of new quality productive forces.
