# A Comprehensive Guide to Investing in the STAR Market Index

**STAR Market Investment Manual - Index Investment Section**

**(1) STAR Market Index System**

The STAR Market includes various types of indices such as broad-based, style, thematic, sub-industry, and cross-market indices. For example, the broad-based index STAR 50 focuses on leading companies by market capitalization in the STAR Market, while indices like STAR AI and STAR Chips focus on specific industries. The STAR Semiconductor Materials and Equipment Index even focuses on specific links in the industrial chain.

As of August 31, **the ETF scale of STAR 50, STAR 100, STAR Entrepreneur 50, STAR Composite Index, STAR AI, and STAR Chips is significantly higher than that of other indices, with the STAR 50 ETF accounting for about 40%.** Most industry-specific indices have relatively small ETF product scales due to their focus on niche areas.

**(2) Review and Comparison of STAR Market Indices**

First, from the review of the mainstream indices in the STAR Market, according to Wind, after September 24, the market significantly warmed up, with all major STAR Market indices rising sharply. Among them, the STAR Chips Index performed particularly well, with a year-to-date increase of 47.64% as of August 31, becoming the leading index, reflecting the AI industry cycle drive.

The STAR 50 Index, as the benchmark broad-based index of the STAR Market, achieved a breakthrough upward, with the core condition being the further improvement in the prosperity of the weighted industries (new generation information technology industry, biotechnology).

According to Wind, on one hand, the expected return of the STAR 50 Index is more easily influenced by the prosperity of the weighted industries, with the market capitalization of the new generation information technology industry in the STAR 50 exceeding 70% by the end of August. On the other hand, the U-shaped performance of the STAR Chips and STAR New Energy relative indices reflects the cyclical changes in industry prosperity from the new energy track to the AI track.

Second, from the horizontal comparison of the STAR Market indices, the following risk-return characteristics are presented: (1) Technology industry indices generally have a higher Sharpe ratio but exhibit greater overall volatility. (2) Broad-based indices have lower overall volatility but a lower Sharpe ratio compared to technology industry indices. (3) The Smart Innovation Value Index has an annualized Sharpe ratio of 0.51, showing good returns with relatively low volatility.

 It is important to note that **the industry concentration of the main indices of the STAR Market is high, and the returns are highly correlated with the prosperity of the weighted industries. For example, the STAR Chip index is more susceptible to the prosperity of the computing power industry, the STAR 100 is more influenced by the prosperity of the innovative drug industry, and the STAR 50 is more affected by the prosperity of the photovoltaic industry.**

**(3) Investment Characteristics of Mainstream Indices of the STAR Market**

We conducted a representative analysis and comparison of the larger ETFs: STAR 50, STAR 100, STAR 200, STAR Composite Index, and STAR Chip Index—

**1\. STAR 50 Investment Characteristics: High Liquidity Weight**

The STAR 50 covers 50 stocks with good liquidity and large market capitalization on the STAR Market, making it an important component of the market's liquidity. The trading volume of the STAR 50 accounts for approximately 20%-40% of the total trading volume of the STAR Market, aggregating the main liquidity of the STAR Market.

**2\. STAR 100 Investment Characteristics: High Weight of Pharmaceuticals**

From the market capitalization distribution of strategic emerging secondary industries, the weight of the biopharmaceutical industry in the STAR 100 is significantly higher than that in the STAR 50.

**4\. STAR Composite Index Investment Characteristics: Strong Representation, Reflects Growth Style**

The STAR Composite Index reflects the growth style of the STAR Market. According to Wind statistics, on one hand, the R&D intensity of the STAR Composite Index in Q1 2025 is far higher than that of other broad-based indices, with R&D expenses accounting for 13% of revenue On the other hand, from the perspective of PEG, the PEG of the STAR Composite Index is less than 1, while its valuation and net profit CAGR are significantly higher than those of other broad-based indices, reflecting distinct characteristics of high R&D investment and high growth.

**5\. Characteristics of Investment in STAR Chips: High Industry Concentration and Strong Correlation with Industry Prosperity**

The STAR Chip Index has a high industry concentration, with its constituent stocks only involving three Shenwan secondary industries, and the weight of the semiconductor industry reaching 96.2%. In addition, the performance of STAR Chips is highly correlated with the prosperity of the semiconductor industry.
