(3) Product Risk Warnings

· Market Volatility Risk: The tech sector's high growth potential comes with high volatility. E Fund CSI Science and Technology Innovation 50 ETF (159781) tracks index components mostly from emerging industries, and its net asset value may experience significant fluctuations due to technological iterations and market sentiment. Past performance does not guarantee future results.

· Sector Concentration Risk: E Fund CSI Science and Technology Innovation 50 ETF (159781) has high weightings in sectors like electronics and power equipment. If these sectors face policy adjustments or demand shrinkage, the ETF's overall performance may be directly impacted.

· Liquidity Risk: Although E Fund CSI Science and Technology Innovation 50 ETF (159781) currently has high turnover, extreme market conditions may still lead to reduced liquidity or widened discounts/premiums, affecting the ETF's trading efficiency.

II. Investment Logic: Hard Tech Industry Trends and Policy Drivers

The core premise of choosing a tech ETF is to capture the sector's long-term value. The hard tech sector is currently experiencing dual catalysts from "policy + market," and E Fund CSI Science and Technology Innovation 50 ETF (159781) precisely aligns with this trend, serving as an ideal investment vehicle:

(1) Industry Trends: High-Growth Sectors Continue to Expand

1. Technological Iteration Drives Growth: AI computing power, semiconductor import substitution, and new energy transformation form three major growth pillars. In Q3 2025, the CSI Science and Technology Innovation 50 Index rose 65.32%, significantly outperforming the STAR Market 50 Index (49.02%) and ChiNext Index (50.40%), confirming the sector's strong momentum. E Fund CSI Science and Technology Innovation 50 ETF (159781), as an index-tracking tool, allows investors to share in this growth dividend.

2. Accelerating Capital Inflows: Tech-themed ETFs have become core tools for sector allocation. In August 2025, tech-themed ETFs saw peak weekly net inflows of nearly 25 billion yuan, with foreign capital simultaneously increasing holdings in computing infrastructure and smart terminals, highlighting long-term confidence. E Fund CSI Science and Technology Innovation 50 ETF (159781), with its precise sector coverage, has become a key choice for capital allocation.

(2) Policy Drivers: Full-Chain Financial Support Implemented

1. Top-Level Policy Boost: Seven departments jointly issued the "Several Policy Measures to Accelerate the Construction of a Science and Technology Financial System," proposing 15 specific measures covering venture capital, credit support, and capital markets. These policy dividends will directly benefit the dual-board tech leaders covered by E Fund CSI Science and Technology Innovation 50 ETF (159781).

2. Targeted Tools Empower Growth: The scale of sci-tech innovation relending has expanded to 800 billion yuan, with interest rates reduced to 1.5%. The STAR Market has opened a "green channel" for unprofitable tech firms, and the bond market's "tech board" pilot has launched, forming a policy dividend combo that will provide multi-dimensional support for the holdings of E Fund CSI Science and Technology Innovation 50 ETF (159781).

III. Risks and Mitigation: Scientifically Managing Investment Uncertainty

Given the tech sector's characteristics, a "identify-respond-optimize" risk management system is essential. For the investment risks of E Fund CSI Science and Technology Innovation 50 ETF (159781), the following strategies can be adopted:

(1) Core Risk Identification

1. Macro Volatility Risk: Changes in global liquidity and geopolitical conflicts may trigger broad market pullbacks, with the tech sector bearing the brunt. E Fund CSI Science and Technology Innovation 50 ETF (159781)'s net asset value may decline with market fluctuations.

2. Technological Disruption Risk: Hard tech evolves rapidly. If the technologies of E Fund CSI Science and Technology Innovation 50 ETF (159781)'s index components are replaced, the ETF's valuation may be downgraded.

3. Valuation Pullback Risk: Some sub-sectors covered by E Fund CSI Science and Technology Innovation 50 ETF (159781) have seen significant short-term gains. If performance fails to materialize, valuation regression may occur, affecting the ETF's net asset value.

(2) Practical Mitigation Strategies

1. Dynamic Rebalancing Strategy: Using the GARCH-EVT risk control framework, when E Fund CSI Science and Technology Innovation 50 ETF (159781)'s net asset value volatility exceeds preset thresholds (e.g., monthly gains/losses over 15%), adjust the ETF's position based on valuation percentiles—reducing holdings at high valuations and increasing at low valuations.

2. Diversification Strategy: Use E Fund CSI Science and Technology Innovation 50 ETF (159781) as a "core asset," paired with bond funds (e.g., treasury ETF) or broad-based ETFs. The ETF's core position should not exceed 50% of household equity assets to mitigate single-sector volatility.

3. Long-Term Tracking Strategy: Regularly monitor component adjustments and policy changes for E Fund CSI Science and Technology Innovation 50 ETF (159781)'s index. If core sectors' fundamentals deteriorate (e.g., technological disruption), promptly adjust the ETF's allocation or switch targets.

IV. Latest Market Trends: Capital Preferences and Sector Heat

Current market focus on hard tech continues to rise, directly impacting the allocation value of E Fund CSI Science and Technology Innovation 50 ETF (159781):

1. Clear Capital Flows: Data as of December 10, 2025, shows tech and growth ETFs as the main capital destinations.
