共享基经丨与AI一起读懂ETF（十九）：科创芯片、科创半导体主题，有何不同？

Core Viewpoint - The article discusses the performance and characteristics of two indices related to the semiconductor sector on the STAR Market, namely the STAR Chip Index and the STAR Semiconductor Materials and Equipment Index, highlighting their differences and similarities in terms of sample selection, industry focus, top-weighted stocks, performance, and valuation levels [1][16]. Group 1: Differences - Sample Selection: The STAR Chip Index includes 50 stocks related to semiconductor materials, equipment, chip design, manufacturing, and testing, with an average market capitalization of approximately 235 billion yuan. In contrast, the STAR Semiconductor Materials and Equipment Index consists of 30 stocks focused on semiconductor materials and equipment, with an average market capitalization of about 149 billion yuan [1][2][3]. - Industry Focus: The STAR Chip Index emphasizes the chip design segment, with over 50% weight in integrated circuit design, while the STAR Semiconductor Materials and Equipment Index focuses on semiconductor materials and equipment, with over 50% weight in semiconductor equipment [4][6]. - Top Ten Weights: The cumulative weight of the top ten stocks in the STAR Chip Index is 58.42%, with companies like Haiguang Information and SMIC having weights exceeding 8%. The STAR Semiconductor Materials and Equipment Index has a cumulative weight of 72.42% for its top ten stocks, with companies like Hu Silicon Industry and Hwa Hai Qing Ke also exceeding 8% [8][10]. Group 2: Performance and Valuation - Index Performance: Over the past year to five years, the STAR Chip Index has outperformed the STAR Semiconductor Materials and Equipment Index. However, the STAR Chip Index has shown slightly higher volatility in the past year, while the latter has had higher annualized volatility over three and five years [11][12]. - Valuation Levels: The STAR Chip Index's price-to-book ratio has risen to above the historical 70th percentile, indicating a high valuation, whereas the STAR Semiconductor Materials and Equipment Index remains around the historical 30th percentile, reflecting a significant difference in market perception between chip design and manufacturing segments [13][16]. Group 3: Similarities - Sample Space: Both indices consist of stocks listed on the STAR Market, requiring a listing period of over six months and excluding stocks with delisting risk warnings, ensuring a focus on established companies [17]. - Industry Category: Both indices belong to the semiconductor industry theme, representing a detailed depiction of the semiconductor sector on the STAR Market, which includes many leading companies in this field [17].
