Quantitative Models and Construction Methods 1. Model Name: Brinson Attribution Model - **Model Construction Idea**: The model is used to decompose the excess returns of active equity funds into stock selection and sector allocation contributions, providing insights into the sources of fund performance [16][19][22] - **Model Construction Process**: The Brinson model calculates excess returns as follows: $ R_{excess} = \sum_{i=1}^{n} (W_{i,f} - W_{i,b}) \cdot R_{i,b} + \sum_{i=1}^{n} W_{i,f} \cdot (R_{i,f} - R_{i,b}) $ - $ W_{i,f} $: Fund weight in sector $ i $ - $ W_{i,b} $: Benchmark weight in sector $ i $ - $ R_{i,f} $: Fund return in sector $ i $ - $ R_{i,b} $: Benchmark return in sector $ i $ The first term represents the allocation effect, and the second term represents the selection effect [16][19] - **Model Evaluation**: The model highlights that stock selection contributes more significantly to excess returns than sector allocation, with stock selection accounting for 83.17% of the total contribution on average [16][22] --- Model Backtesting Results 1. Brinson Attribution Model - Average stock selection contribution: 5.38% per half-year [22] - Probability of positive stock selection returns: 69.12% [23] - Probability of positive sector allocation returns: 53.66% [23] --- Quantitative Factors and Construction Methods 1. Factor Name: Fund Stability Factor - **Factor Construction Idea**: This factor measures the stability of a fund's sector allocation and its impact on outperforming benchmarks [10][12] - **Factor Construction Process**: Funds are categorized into 16 groups based on static and dynamic sector allocation characteristics: - Static categories: Highly diversified, diversified, concentrated, highly concentrated - Dynamic categories: Highly stable, stable, rotational, highly rotational The average probability of outperforming benchmarks is calculated for each group [10][12] - **Factor Evaluation**: Funds with highly stable and diversified sector allocations have the highest probability of outperforming benchmarks, exceeding 73% on average [12][14] 2. Factor Name: Style Consistency Factor - **Factor Construction Idea**: This factor evaluates the consistency of a fund's style (e.g., large-cap value) and its correlation with performance [27][30] - **Factor Construction Process**: Funds are classified based on their style consistency over time: - Long-term stable allocation - Majority-time allocation - Partial-time allocation - Rare-time allocation The probability of outperforming benchmarks is calculated for each group [27][28] - **Factor Evaluation**: Funds with long-term stable large-cap value styles have the highest probability of outperforming benchmarks, reaching 79.77% [28][30] --- Factor Backtesting Results 1. Fund Stability Factor - Highly diversified-highly stable funds: - Probability of outperforming benchmark: 73.12% - Probability of outperforming benchmark +10%: 57.29% [12] 2. Style Consistency Factor - Long-term stable large-cap value funds: - Probability of outperforming benchmark: 79.77% - Probability of outperforming benchmark +10%: 69.05% [28]

Core Viewpoint - The current investor enthusiasm for WFG (Wells Fargo Fund) is primarily driven by trust in the personal brand of Fan Yan rather than a comprehensive recognition of the company's investment research system [1][10] Group 1: Company Performance and Strategy - WFG announced a joint investment of no less than 25 million yuan by senior management and proposed fund managers in the upcoming fund product, marking the first public fund launched after Fan Yan joined [1] - WFG's revenue and net profit peaked in 2021 at 8.306 billion yuan and 2.564 billion yuan respectively, but have since faced continuous pressure, with revenues decreasing to 7.359 billion yuan, 6.715 billion yuan, and 6.405 billion yuan from 2022 to 2024 [10][14] - The company has struggled to adapt to industry changes, particularly in the wake of fee reforms, contrasting sharply with leading firms like E Fund and Huaxia Fund that have improved their financial conditions [14] Group 2: Fund Management and Performance - Fan Yan's management of the fund "Yuanxin Yongfeng Youjia Life" resulted in a return of 188.84% and an annualized return of 13.39% before her departure, making it one of the top performers in its category [6][10] - Following Fan Yan's exit, the management scale of the "Yuanxin Yongfeng Youjia Life" fund significantly shrank from 4.655 billion yuan to 1.422 billion yuan, a decrease of 69.45% [10] - Despite a modest return of 2.49% for the "WFG Steady Growth Fund" under Fan Yan's leadership, it attracted substantial net subscriptions of 4.492 billion yuan and 5.731 billion yuan in the fourth quarter of 2024 and the first quarter of 2025 respectively [13] Group 3: Leadership Changes and Market Impact - The appointment of Gao Jian as the new general manager of Yuanxin Yongfeng Fund marked a shift in management, with a strategic focus on fixed-income products, diverging from Fan Yan's emphasis on equity investments [9][10] - The reliance on "star manager" strategies has led to a decline in overall performance for WFG, as evidenced by the shrinking influence of its equity investment products [10][14]
