Huaan Securities· 2025-08-28 11:06
Quantitative Models and Construction - **Model Name**: Active and Passive Rebalancing Metrics **Construction Idea**: Decompose quarterly portfolio weight changes into active discretionary decisions and passive return-driven changes to analyze fund manager behavior [38][40][42] **Construction Process**: - Formula: $W_{i,j,t}-W_{i,j,t-1}=\underbrace{W_{i,j,t}-\widehat{W}_{i,j,t}}_{\text{Active}_{i,j,t}}+\underbrace{\widehat{W}_{i,j,t}-W_{i,j,t-1}}_{\text{Passive}_{i,j,t}}$ $\widehat{w}_{i,j,t}=\frac{\left(1+r_{i,t}\right)\,w_{i,j,t-1}}{\sum\left(1+r_{i,t}\right)\,w_{i,j,t-1}}$ - **Active**: Residual weight changes after removing mechanical effects, capturing discretionary rebalancing [40][42] - **Passive**: Weight changes driven by market returns assuming no trading activity [40][41] **Evaluation**: Captures fund managers' preferences for managing portfolio concentration and distinguishes between minor adjustments and large-scale asset rotation [42][43] - **Model Name**: Threshold Demand **Construction Idea**: Focus on concentrated positions exceeding 2% of fund AUM to measure diversification-driven demand [82][83] **Construction Process**: Formula: $Threshold Demand_{i,t}=\frac{\sum_{j}\left(\widehat{w}_{i,j,t}-w_{i,j,t-1}\right)\cdot I(w_{i,j,t-1}>2\%)\cdot\text{Shares}_{i,j,t-1}}{\sum_{j}\text{Shares}_{i,j,t-1}}$ - Uses only concentrated positions (10% of fund holdings) where portfolio size and concentration matter [82][83] **Evaluation**: Effectively isolates positions where diversification constraints are most impactful [83] - **Model Name**: Fitted Demand **Construction Idea**: Use spline coefficients from weight ranges to construct demand metrics based on rebalancing intensity [83][84] **Construction Process**: Formula: $Fitted Demand_{i,t}=\frac{\sum_{j}\left(\widehat{W}_{ij,t}-W_{ij,t-1}\right)\cdot\beta_{weight}\cdot\text{Shares}_{i,j,t-1}}{\sum_{j}\text{Shares}_{i,j,t-1}}$ - $\beta_{weight}$ represents rebalancing intensity coefficients for different weight ranges [83][84] **Evaluation**: Focuses on positions within 2%-6.5% of fund AUM, capturing nuanced rebalancing behavior [83][84] Model Backtesting Results - **Active and Passive Metrics**: - Contemporaneous Active adjustment for 1% Passive weight change: -0.234% [44][49] - Next-quarter Active adjustment for 1% Passive weight change: -0.171% [44][49] - **Threshold Demand**: - Standard deviation: 0.15% - Predicts equity fund sell probability increase by 1.28%-2.20% [85][86] - **Fitted Demand**: - Standard deviation: 0.03% - Predicts equity fund sell probability increase by 0.5%-0.67% [85][86] Quantitative Factors and Construction - **Factor Name**: Rebalancing Demand **Construction Idea**: Aggregate passive-driven portfolio changes to measure demand for large-cap stocks [81][82] **Construction Process**: Formula: $Rebalancing Demand_{i,t}=\frac{\sum_{j}\left(\widehat{w}_{i,j,t}-w_{i,t-1}\right)\cdot\text{Shares}_{i,j,t-1}}{\sum_{j}\text{Shares}_{i,j,t-1}}$ - Aggregates passive-driven changes across all observed mutual funds [81][82] **Evaluation**: Predicts short-term price pressure and subsequent reversals for large-cap stocks [82][88] Factor Backtesting Results - **Rebalancing Demand**: - Predicts short-term returns: -0.44% (t=-3.21) for first 35 trading days [88][89] - Predicts subsequent reversals: +0.27% (t=2.60) for remaining quarter [88][89] - **Threshold Demand**: - Predicts short-term returns: -0.348% (t=-3.719) for first 35 trading days [88][89] - Predicts subsequent reversals: +0.178% (t=2.508) for remaining quarter [88][89] - **Fitted Demand**: - Predicts short-term returns: -0.460% (t=-3.598) for first 35 trading days [88][89] - Predicts subsequent reversals: +0.253% (t=2.616) for remaining quarter [88][89] Additional Observations - **Impact on Momentum Portfolios**: - Adjusting for rebalancing demand improves momentum portfolio returns by 230% for large-cap stocks [114] - Suggests diversification-driven demand weakens traditional momentum strategies [114] - **Price Pressure and Reversals**: - Large-cap stocks experience V-shaped return patterns due to rebalancing demand [93][94] - Short-term price pressure followed by reversals aligns with non-fundamental demand effects [93][94]
