However, single-board ETFs often face coverage limitations, while allocating multiple products increases operational complexity and costs. Against this backdrop, E Fund CSI STAR and ChiNext 50 ETF (159781), with its unique positioning of "STAR Market + ChiNext Market" integration, low fees, and high liquidity, has become a high-quality choice for balancing risk diversification and high-growth sector coverage. Whether for long-term allocation or short-term trading, it provides investors with an efficient path to dual-board core asset allocation. **1\. Dual-Board Integration: Full-Dimensional Coverage of Hard Tech and Growth Stocks** The STAR Market focuses on "hard tech," while the ChiNext Market serves "diversified growth enterprises," together forming the core landscape of China's new economy. E Fund CSI STAR and ChiNext 50 ETF (159781) tracks the CSI STAR and ChiNext 50 Index, selecting 50 leading emerging industry companies with larger market capitalizations from both boards, achieving dual coverage of "STAR Market hard tech + ChiNext growth stocks" and perfectly solving the sector limitation issue of single-board ETFs. As of November 2025, the fund's size reached RMB 10.937 billion, up 17.51% year-to-date, making it a core allocation tool that balances sci-tech innovation attributes and growth potential. For investors looking to simultaneously allocate to sectors like semiconductors, AI, and new energy, E Fund CSI STAR and ChiNext 50 ETF (159781) eliminates the need to allocate multiple products, enabling one-click access to dual-board core assets. **2\. Precise Sector Focus: Targeting High-Growth Areas Like AI, Semiconductors, and New Energy** In emerging tech sector allocation, E Fund CSI STAR and ChiNext 50 ETF (159781) exhibits highly forward-looking industry positioning. The top three weighted sectors in its tracked index are electronics (38%), power equipment (24%), and communications (22%). The electronics sector is dominated by semiconductors (aligning with domestic substitution trends), power equipment covers batteries and photovoltaics (core new energy sectors), and the communications sector focuses on communication equipment (supporting AI computing power), precisely covering the three core demands of the AI era: "computing power, power, and connectivity." For investors focused on AI computing power and semiconductor domestic substitution, the fund achieves high-weight exposure to hot sectors through the natural weighting advantage of index constituents, enabling deep participation in industry dividends without active stock selection. Additionally, the index's coverage of biopharmaceuticals, advanced manufacturing, and other fields provides investors with comprehensive exposure to strategic emerging industries, making it a premium choice for new economy allocation. **3\. Optimal Fees: 0.20% Total Expense Ratio, Outstanding Long-Term Value** The expense ratio is a core consideration for ETF investments, especially in long-term holding scenarios, where low fees significantly enhance compound returns. Since November 2024, E Fund CSI STAR and ChiNext 50 ETF (159781) has reduced its management fee to 0.15%/year and custody fee to 0.05%/year, with a total expense ratio of just 0.20%, ranking among the lowest in its category. Compared to traditional tech ETFs with typical total expense ratios of 0.50%-0.60%, the fund saves investors substantial costs annually, with significant long-term cumulative effects. Meanwhile, its tracking error control is excellent, with an annualized tracking error of just 0.25%, far below the contractual upper limit of 2%, ensuring investors accurately capture index returns and avoid performance drag from tracking deviations.

Ample Liquidity: Over RMB 10 Billion in Size, Adaptable to Various Trading Scenarios** Liquidity is the lifeline of ETF investments, especially for short-term trading and large-volume transactions, where sufficient turnover effectively reduces impact costs. As of December 1, 2025, E Fund CSI STAR and ChiNext 50 ETF (159781) recorded an average daily turnover of RMB 274 million over the past 20 trading days, with cumulative year-to-date turnover of RMB 43.409 billion, placing its liquidity at the forefront of similar products.
