Quantitative Models and Construction Methods 1. Model Name: Wantushi AI Model - **Model Construction Idea**: The Wantushi AI model evaluates indices based on their potential upward probability and selects ETFs with favorable characteristics for investment[6] - **Model Construction Process**: 1. The model assigns a score to indices based on their upward probability. Indices with scores above 0.8 are selected[6] 2. For each selected index, the corresponding ETFs are identified[6] 3. Among these ETFs, those with a 30-day average daily trading volume exceeding 30 million RMB are retained[6] 4. Finally, the ETF with the lowest IOPV premium rate for each index is chosen[6] - **Model Evaluation**: The model systematically filters ETFs based on liquidity and valuation metrics, ensuring a focus on high-quality investment options[6] --- Backtesting Results of Models 1.
