Analysis of Strategy Value Index Win Rate Improvement and Hua Zheng Value Preferred 50 Index Selection Logic

Based on your question, I will conduct an in-depth analysis from two dimensions: the win rate improvement mechanism of strategy value indices and the stock selection logic of the Hua Zheng Value Preferred 50 Index.

According to data analysis, strategy value indices do show a significant win rate improvement advantage over pure value indices in the A-share market:

• Hua Zheng Value Preferred 50 Index
  : Annual win rate reaches
  80%
  , 10-year cumulative return **265.88%
• Pure Value Indices
  : Annual win rate is about
  60%
  , 10-year cumulative return about **120%
• Win Rate Improvement Margin
  : Strategy value indices have a win rate improvement of about
  20 percentage points
  compared to pure value indices.

Strategy value indices adopt a composite factor model, which not only considers traditional valuation indicators (PE, PB, PS) but also integrates:

• Quality Factors
  : Profit quality indicators such as ROE, ROA, and gross profit margin
• Growth Factors
  : Revenue growth rate, net profit growth rate
• Momentum Factors
  : Price trends, capital flows
• Risk Factors
  : Volatility, maximum drawdown control

Unlike the fixed weights of traditional value indices, strategy indices are based on:

• Adjusting factor weights according to changes in market environment
• Industry rotation based on industry prosperity
• Timely position adjustment based on changes in individual stock fundamentals

• Setting maximum drawdown thresholds and automatically reducing positions
• Limiting individual stock concentration to prevent excessive exposure to single stock risks
• Setting industry allocation caps to avoid concentrated industry risks

• Exclude stocks with average daily turnover in the past 6 months lower than 50% of the market average
• Exclude stocks with a total market value below 5 billion yuan
• Ensure constituent stocks have good liquidity

• Valuation Dimension
  (weight 40%):
  • Price-to-Earnings Ratio (TTM): Below industry average
  • Price-to-Book Ratio: More than 20% below historical average
  • Price-to-Sales Ratio: Comparative advantage in the same industry
  • EV/EBITDA: Degree of relative undervaluation

• Quality Dimension
  (weight 35%):
  • ROE: ≥15% for 3 consecutive years
  • Asset-Liability Ratio: ≤60%
  • Cash Flow Ratio: Operating cash flow/net profit ≥0.8
  • Gross Profit Margin: Stable and higher than industry average

• Growth Dimension
  (weight 25%):
  • Compound Revenue Growth Rate: ≥10% in the past 3 years
  • Compound Net Profit Growth Rate: ≥12% in the past 3 years
  • R&D Investment Ratio: ≥3% (for technology enterprises)

• Using the Black-Litterman model for expected return adjustment
• Controlling portfolio risk through risk parity methods
• Considering factor crowding to avoid over-chasing popular factors

The index follows a “value + quality” dual-drive in industry allocation:

• Financial Industry
  (25-30%): Select low-valued, high-rated banks and insurance companies
• Consumer Industry
  (20-25%): Focus on leading enterprises with brand moats
• Manufacturing Industry
  (15-20%): Select companies with cost advantages and technical barriers
• Utilities Industry
  (10-15%): High-dividend targets with stable cash flows

• Quarterly Adjustment
  : Adjust constituent stocks once every quarter
• Temporary Adjustment
  : Adjust immediately when individual stocks have major fundamental changes
• Weight Optimization
  : Dynamically optimize the weights of each constituent stock according to market environment

• Maximum single position does not exceed 5%
• Single industry weight does not exceed 35%
• Monthly turnover rate controlled within 15%

• Setting an 8% maximum drawdown warning line
• Using VIX index for market panic monitoring
• Establishing stress test models to cope with extreme market conditions

1. Systematic Advantage
   : Overcome human weaknesses through scientific quantitative models
2. Adaptability Advantage
   : Can dynamically adjust strategies according to market environment
3. Risk Control Advantage
   : Built-in multiple risk management mechanisms

1. Long-Term Holding
   : Strategy value indices are suitable as core allocations for long-term holding
2. Regular Evaluation
   : It is recommended to evaluate the index performance and strategy effectiveness every six months
3. Portfolio Allocation
   : Can be used with other strategy indices to diversify risks

As the institutionalization of the A-share market and investor maturity increase, strategy value indices are expected to continue outperforming traditional indices and provide investors with more stable long-term returns.
