Quantitative Models and Construction Methods 1.

It aims to identify stocks with both fundamental support and technical resonance from an analyst-recommended stock pool[14][17] - **Model Construction Process**: 1. **Analyst Recommendation Pool**: Constructed using three types of analyst recommendation events: upward earnings forecast revisions, first-time coverage, and research reports with unexpected positive titles[17] 2. **Dual-Layer Selection**: - **Fundamental Analysis**: Select stocks with strong fundamental support - **Technical Analysis**: Identify stocks with technical resonance 3. **Backtesting**: The backtesting period is from January 1, 2010, to December 31, 2025. The portfolio assumes a fully invested state and considers transaction costs[17] - **Model Evaluation**: The model demonstrates strong performance with significant annualized returns and excess returns over the Hang Seng Index[17] 2. Factor Name: 250-Day New High Distance - **Factor Construction Idea**: This factor measures the distance of the latest closing price from the 250-day high, reflecting the momentum effect in stock prices[21][23] - **Factor Construction Process**: 1. **Formula**: $ 250\text{-Day New High Distance} = 1 - \frac{\text{Close}_{t}}{\text{ts\_max}(\text{Close}, 250)} $ - $\text{Close}_{t}$: Latest closing price - $\text{ts\_max}(\text{Close}, 250)$: Maximum closing price over the past 250 trading days 2. **Interpretation**: - If the latest closing price reaches a new high, the factor value is 0 - If the price falls from the high, the factor value is positive, indicating the degree of decline[23] 3. **Screening Criteria**: - Stocks with high analyst attention (at least five buy or overweight ratings in the past six months) - Top 20% in 250-day price change within the sample pool - Stability and trend continuation metrics, such as price path smoothness and average 250-day new high distance over the past 120 days[24] --- Model Backtesting Results 1.

Market Overview - The three major U.S. stock indices closed mixed, with the Dow Jones up 0.1%, the Nasdaq down 0.22%, and the S&P 500 up 0.05%. The Russell 2000 small-cap index rose approximately 1.2%. All three indices recorded declines over the past week, with the Nasdaq showing the largest drop, indicating cautious market sentiment [1]. - Most popular tech stocks declined, with Nvidia and Apple dropping over 2%, and Google, Meta, and Broadcom falling over 1%. Investor concerns about the potential impact of artificial intelligence on traditional industries have heightened risk-averse sentiment [3]. Economic Indicators - The U.S. January CPI year-on-year decreased from 2.7% to 2.4%, the lowest since May 2025, while the core CPI fell from 2.6% to 2.5%, the lowest since March 2021. The core CPI rose 0.3% month-on-month, slightly above December's 0.2% increase [9][10]. - Following the CPI report, traders increased their expectations for interest rate cuts this year, with a 50% chance of three cuts by year-end.

This represents a significant reversal of nearly RMB 600 billion [16][18]. - The core reason for Meituan's drastic performance change is the profit collapse in its most profitable segment, "core local business," which is expected to incur an operating loss of RMB 68 billion to RMB 70 billion in 2025, compared to an operating profit of RMB 524.15 billion in 2024. This is attributed to unprecedented competition in the industry and strategic increases in ecosystem investments [18][20]. - Meituan plans to increase investments in marketing, rider incentives, and operational efficiency to counteract the losses, while also expanding its overseas business [20]. Market Sentiment and Trends - The Hang Seng Tech Index has shown weakness, declining 6.26% since February, influenced by liquidity shocks. Analysts suggest that the fundamentals and bullish logic for the Hong Kong tech sector remain unchanged [21]. - The performance of the Hang Seng Tech Index in February may be driven by macroeconomic data, policy pricing, and earnings verification, with U.S. inflation and employment data being key factors affecting valuation elasticity in Hong Kong tech stocks [21].
