Core Viewpoint - The collective failure of traditional price and volume factors since 2026 has led to the emergence of a momentum-based industry rotation model, which provides a potential solution for enhancing portfolio stability and excess returns [1][4][54]. Group 1: Industry Rotation Model Characteristics - The industry rotation factor has shown strong characteristics, with a monthly Information Coefficient (IC) of 5.3% and an Information Coefficient Information Ratio (ICIR) of 4.0, indicating its robust performance [26][54]. - The industry rotation model has been effective in improving performance within traditional multi-factor frameworks, significantly enhancing excess returns and halting the decline in excess performance seen in recent years [2][54]. Group 2: Challenges and Conflicts - The industry rotation factor faces conflicts with the industry deviation constraints commonly used in index-enhanced frameworks, which can negatively impact its effectiveness [2][54]. - When applying the standard industry deviation constraint of 2% and individual stock deviation of 0.5%, the performance of the portfolio has declined, with excess returns turning negative in 2025 [2][54]. Group 3: Optimal Usage Strategy - The best approach for utilizing the industry rotation factor is to maintain the individual stock deviation constraint at 0.5% while relaxing the industry deviation constraint from 2% to 5%, which has shown to improve overall excess returns and reduce maximum drawdowns [3][54]. - Increasing the industry deviation to 4% or 5% has resulted in better overall performance, with maximum drawdowns decreasing, indicating a balanced approach to enhancing excess returns while controlling risk [3][54].

Report Industry Investment Rating No information provided in the content. Core Viewpoints of the Report - The collective failure of traditional quantitative and price factors in 2026 is related to their reverse logic, providing a scenario for the factorization of the industry rotation model with momentum characteristics [2]. - The industry rotation model has long lacked practical use scenarios, but its stability in excess returns meets the requirements of stock - selection factors, laying a foundation for its transformation into a stock - selection factor [2]. - The industry rotation factor has good factor characteristics, with a monthly IC of 5.3% and an ICIR of 0.40, and it can enhance the performance of the traditional multi - factor model [2][30]. - The industry rotation factor conflicts with the industry deviation constraints in the index - enhancement framework, but it still contributes to stock - selection and cannot be replaced by simple industry over - under - weighting or portfolio strategies [2][61]. - Keeping the individual stock deviation constraint at 0.5% while relaxing the industry deviation constraint is currently the best way to use the industry rotation factor [2][62]. Summary by Relevant Catalogs 1. Finding a Usage Scenario for the Industry Rotation Model: Starting from the Failure of Quantitative and Price Factors - Since 2026, index - enhancement funds tracking the CSI 500 index and active quantitative funds' quasi - index products have mostly underperformed the CSI 500 index. As of the end of January, all CSI 500 index - enhancement products underperformed the index, with an average underperformance of 3.46%, and active quantitative products underperformed by 1.96% on average [5]. - The main failed factors are quantitative and price factors such as liquidity, reversal, low - volatility, and market value, whose logic is mostly reverse - oriented. In the context of a rapid rise in the index and continuous driving of some popular sectors and themes in January, these factors not only failed but also reversed [7]. - The industry rotation model is a strongly momentum - driven model. The Shenwan Hongyuan Industry Rotation Model emphasizes momentum in its technical, fundamental, and capital aspects, and can complement traditional quantitative and price factors with reverse logic [10]. - The industry rotation model has long lacked practical use scenarios. Its long - only portfolio performance is not outstanding, and its stable excess return relative to the average of all industries has no practical significance for most investors [13][16]. 2. Factorization of the Industry Rotation Model - Transforming the industry model into a stock - selection model is relatively easy. By splicing the scores of each stock's industry in the industry model, a stock - based score can be obtained. However, due to the large number of stocks belonging to the same industry, the factor shows a segmented score characteristic, and orthogonal processing is required [22]. - The monthly IC of the original industry rotation factor has a correlation of over 0.4 with the growth factor. After orthogonalizing the original industry rotation factor against the growth factor, its performance shows good monotonicity, and its cumulative IC and long - short performance are excellent [23][25]. - From 2017 to January 2026, the monthly average IC of the industry rotation factor reached 5.3%, stronger than other traditional factors, and the ICIR was 0.40, ranking third, indicating excellent factor characteristics [30]. 3. Usage and Comparative Analysis of the Industry Rotation Factor - **Comparison of Four - Factor and Five - Factor Models**: Adding the industry rotation factor to the four - factor equal - weighted model to form a five - factor model can significantly improve the model's performance, especially in recent years, enhancing the model's offensive ability in a bull market and the stability of excess returns [35][38]. - **Factor Equal - Weighting vs. ICIR Weighting**: Changing the factor weighting method from simple equal - weighting to ICIR weighting does not show better results. The five - factor equal - weighted combination with the industry rotation factor performs best in each year and is the only combination with positive excess returns in all years [39]. - **Moving towards the Index - Enhancement Framework: Adding Industry Neutrality and Individual Stock Deviation Constraints**: Adding industry deviation and individual stock constraints to the model makes the industry rotation factor conflict with the industry deviation constraint. Although it can control the maximum drawdown in some years, it also reduces the performance of the five - factor model in terms of returns in some cases. In 2025, the annual excess return becomes negative after adding constraints [41][42]. - **Method of Constraining Industry Deviation Ranking through Industry Scoring**: Using industry scoring to control industry deviation ranking without using the industry rotation factor for stock - selection results in weaker performance compared to the five - factor model with industry and individual stock constraints. This method is not the best option [44]. - **Multi - Strategy Portfolio: Using Industry Rotation as a Satellite Portfolio "Platter"**: Using the industry rotation factor as a separate strategy to form a satellite portfolio and combining it with a four - factor portfolio does not show obvious advantages. The performance of the "platter portfolio" is difficult to outperform, and only the 3:7 ratio combination has a slight competitive edge, but it also shows negative excess returns in January 2026 [50]. - **Current Best Solution: Relaxing Industry Deviation while Maintaining Individual Stock Deviation Constraints**: Keeping the individual stock deviation constraint at 0.5% and relaxing the industry deviation constraint to 4% or 5% can improve the overall excess return of the portfolio, reduce the maximum drawdown of excess returns, and have a negligible impact on tracking error. This is currently the best way to use the industry rotation factor [53][57]. 4. Summary - The industry rotation model has long lacked practical use scenarios, but its stability characteristics provide a basis for its transformation into a stock - selection factor. - The industry rotation factor has good characteristics and can enhance the performance of the traditional multi - factor model, but it conflicts with the industry deviation constraint in the index - enhancement framework. - The industry rotation factor contributes to stock - selection and cannot be replaced by simple strategies. Relaxing the industry deviation constraint while maintaining the individual stock deviation constraint is the best solution [60][61][62].
