[Q&A] Q1: The STAR market threshold is 500,000 RMB. What low-threshold ways are there for retail investors to invest in STAR chips? A: The participation threshold for individual investors in the STAR market is relatively high, requiring investors to have an average daily asset of no less than 500,000 RMB over 20 trading days (excluding margin financing and securities lending), and investment experience of no less than 24 months. For investors who do not meet this threshold, the minimum investment threshold for the STAR Chip Design ETF SPDB (589250) is only 100 shares, allowing for lower-threshold investment participation with convenient trading. Q2: Compared to the STAR 50 ETF, how is the long-term return of the index tracked by this ETF? A: The SSE STAR Chip Design Theme Index (950162) has gained 207.14% since 2023, while the STAR 50 gained 73.27% during the same period, with the latter's gain being less than 40% of the former's (Data source: Wind, as of 2026.6.12). The core difference lies in the fact that the STAR 50 covers all industries in the STAR market, with limited chip exposure; whereas the SSE STAR Chip Design Theme Index focuses on chip design companies in the STAR market, with higher track purity. Q3: What is the difference between chip design indices and semiconductor equipment indices? A: The SSE STAR Chip Design Theme Index (950162) excludes semiconductor materials/equipment, manufacturing, and packaging/testing segments, anchoring only on chip design, the most innovative sub-sector in the semiconductor industry chain—digital chip design 79.6% + analog chip design 15.4% = 95% (Data source: Wind, as of 2026.5.29). If you are bullish on the chip design segment, this index is one of the purest choices among similar ones. Q4: Memory chips have risen so much. Does this index still benefit? A: In the top ten weights of the SSE STAR Chip Design Theme Index (950162), the memory direction (Montage Technology 9.27% + Biwin Storage 7.39% + Puya Shares 3.26%) totals nearly 20% (Data source: Wind, as of 2026.8.7). The global memory chip super-cycle is still ongoing, and South Korea's 4,755 trillion KRW expansion plan points to doubling DRAM capacity in five years. The memory direction remains an important weight component of this index. Q5: Does this index have earnings support? A: The net profit attributable to parents of this index was 13.109 billion RMB in 2025, up 191.96% year-on-year; in the first quarter of 2026, net profit attributable to parents was 6.425 billion RMB, up 260.14% year-on-year (Data source: Wind). High earnings growth, not pure conceptual speculation. Q6: What is the core difference between this fund and other semiconductor ETFs? A: The product's underlying index layout focuses on the chip design segment of the STAR market, excluding semiconductor materials/equipment, manufacturing, and packaging/testing. The combined weight of the top ten constituent stocks is 57.15%, with concentrated computing power leaders. Q7: What standard is the tracking error of this fund controlled at? A: Under normal circumstances, it strives to keep the absolute value of the daily average tracking deviation below 0.2%, and the annualized tracking error does not exceed 2%. Q8: What are the advantages of investing in this fund? A: First, it precisely focuses on the core track of chip design in the STAR market, with digital chips and analog chips accounting for a combined 94.17% (Data source: Wind, as of 2026.8.7, industry classification is Shenwan Level III); Second, it benefits from the dual dividends of explosive growth in the global semiconductor market and accelerated domestic substitution; Third, the news side has received multiple positive catalysts, and industry prosperity continues to rise; Fourth, it allows for one-click layout of chip design leaders through ETF form, dispersing individual stock risks; Fifth, starting from 100 shares, it provides a participation channel for individual investors who cannot meet the 500,000 RMB account opening threshold for the STAR market.
