Quantitative Models and Construction Methods - **Model Name**: "One-sentence" automated backtesting framework **Model Construction Idea**: The framework leverages AI programming tools and a rules-driven workflow to transform natural language strategy descriptions into structured data queries, stock screening, portfolio construction, and backtesting results[7][10][13] **Model Construction Process**: 1. **Natural Language Input**: Users describe strategies in plain language, e.g., "monthly strategy, select stocks with market cap < 40 billion, ROE and ROA in the top 50%, and choose the 30 stocks with the lowest PE"[24] 2. **Data Mapping**: The system uses a standardized database query interface and a WIND data dictionary to map strategy elements (e.g., market cap, ROE, ROA, PE) to specific database tables and fields[7][13][22] - Example tables: - **AShareEODDerivativeIndicator**: Fields include `S_VAL_MV` (market cap) and `S_VAL_PE` (PE ratio)[24] - **AShareFinancialIndicator**: Fields include `S_FA_ROE` (ROE) and `S_FA_ROA` (ROA)[24] 3. **Portfolio Construction**: The system generates standardized portfolio data with three key elements: `date`, `asset`, and `weight`. It automatically adjusts for user-defined rebalancing frequencies (daily, weekly, monthly, quarterly)[13][15] 4. **Backtesting**: The framework runs backtests using the constructed portfolio and outputs performance metrics, risk analysis, and detailed reports[7][24] **Model Evaluation**: The framework is innovative in bridging natural language and structured data, enabling rapid strategy validation. However, its reliance on WIND data quality and AI model accuracy may introduce risks[7][13][24] Model Backtesting Results - **"One-sentence" automated backtesting framework**: - **Annualized Return**: 2020: 18.96%, 2021: 16.70%, 2022: 8.21%, 2023: 15.66%, 2024: 7.15%, 2025: 37.70%[29] - **Annualized Volatility**: 2020: 20.95%, 2021: 23.41%, 2022: 24.94%, 2023: 13.94%, 2024: 33.71%, 2025: 17.02%[29] - **Sharpe Ratio**: 2020: 0.91, 2021: 0.71, 2022: 0.33, 2023: 1.12, 2024: 0.21, 2025: 2.21[29] - **Maximum Drawdown**: 2020: -5.90%, 2021: -9.59%, 2022: -18.31%, 2023: -6.72%, 2024: -14.18%, 2025: -3.76%[29] - **Win Rate**: 2020: 66.67%, 2021: 66.67%, 2022: 66.67%, 2023: 50.00%, 2024: 50.00%, 2025: 75.00%[29] - **Calmar Ratio**: 2020: 3.21, 2021: 1.74, 2022: 0.45, 2023: 2.33, 2024: 0.50, 2025: 10.03[29] Quantitative Factors and Construction Methods - **Factor Name**: Small-cap value factor **Factor Construction Idea**: Select stocks with small market capitalization and strong financial performance, then rank by valuation metrics[24] **Factor Construction Process**: 1. **Stock Pool Definition**: Limit to stocks listed on Shanghai and Shenzhen exchanges with market cap < 40 billion[24] 2. **Financial Screening**: Filter stocks with ROE and ROA in the top 50% of the defined pool[24] 3. **Valuation Ranking**: Rank remaining stocks by ascending PE ratio and select the top 30[24] **Factor Evaluation**: The factor effectively combines size, profitability, and valuation metrics, aligning with traditional value investing principles[24] Factor Backtesting Results - **Small-cap value factor**: - **Annualized Return**: 2020: 18.96%, 2021: 16.70%, 2022: 8.21%, 2023: 15.66%, 2024: 7.15%, 2025: 37.70%[29] - **Annualized Volatility**: 2020: 20.95%, 2021: 23.41%, 2022: 24.94%, 2023: 13.94%, 2024: 33.71%, 2025: 17.02%[29] - **Sharpe Ratio**: 2020: 0.91, 2021: 0.71, 2022: 0.33, 2023: 1.12, 2024: 0.21, 2025: 2.21[29] - **Maximum Drawdown**: 2020: -5.90%, 2021: -9.59%, 2022: -18.31%, 2023: -6.72%, 2024: -14.18%, 2025: -3.76%[29] - **Win Rate**: 2020: 66.67%, 2021: 66.67%, 2022: 66.67%, 2023: 50.00%, 2024: 50.00%, 2025: 75.00%[29] - **Calmar Ratio**: 2020: 3.21, 2021: 1.74, 2022: 0.45, 2023: 2.33, 2024: 0.50, 2025: 10.03[29]

Core Viewpoint - The sell-side research business in China's securities industry is considered the "crown jewel," reflecting a brokerage's professional capability and comprehensive influence, despite not generating significant profits [2][3]. Summary by Sections Sell-Side Research Capability Measurement - The measurement of sell-side research capabilities among brokerages is primarily based on the total amount of commission allocated by public funds and their rankings. The recent commission ranking, following the public fund commission reform, highlights the strengths and weaknesses of research and service capabilities [3][4]. Top Tier: Expected Reshuffling and Surprises - The merger of two traditional institutions, Guotai Junan and Haitong Securities, into Guotai Haitong Securities has created a reshuffling opportunity in the top tier of sell-side research. However, the merged entity did not surpass CITIC Securities, which remains the leader with a significant gap in commission income [4][5]. Commission Rankings - CITIC Securities leads with a total commission of 319 million yuan, holding a market share of 7.13%. Guotai Haitong Securities follows with 268 million yuan, while GF Securities ranks third with 250 million yuan [5][6][8]. Competitive Landscape - The competition for the second and third positions in the sell-side research market is expected to be intense, particularly between Guotai Haitong and GF Securities, given their close commission figures [7]. First Tier: Strong Contenders - The top ten brokerages are characterized by complete systems, strong teams, and significant influence. The rankings are subject to change based on performance in the latter half of the year [9][10]. Rising Institutions - Zhejiang Securities, Shenwan Hongyuan, and CICC have shown significant improvements in their rankings without the benefit of mergers, indicating genuine growth in their research capabilities [11][12]. Second Tier: The "Billion Club" - The second tier of brokerages, ranked 11th to 20th, is highly competitive, with many firms vying for the "billion club" threshold. The top three in this tier are Tianfeng Securities,招商证券, and东吴证券, all closely matched in commission income [14][15]. Notable Exceptions - Guolian Minsheng Securities, which also underwent a merger, is uniquely positioned in the rankings due to its late merger timing, potentially affecting its future standings [16]. Bottom Tier: Rare Positive Growth - Among the bottom ten brokerages, there are rare examples of positive growth, particularly华源证券 and华福证券, which have seen significant increases in their commission income due to strategic hires and team expansions [17][19].
