申万金工成长组合2.0：非线性倾斜加权提升组合收益弹性

Report Industry Investment Rating No information provided in the report. Core Viewpoints of the Report - The report attempts to upgrade the Shenwan Goldsmith Growth Portfolio by using the industry rotation model, aiming to enhance the portfolio's return performance and build the Shenwan Goldsmith Growth Portfolio 2.0 version [3]. - The nonlinear tilt - weighted method is used to adjust the weights of individual stocks in the portfolio, effectively improving the portfolio's return and enhancing its return elasticity without sacrificing return stability [21][34]. Summary by Relevant Catalogs 1. Shenwan Goldsmith Growth Portfolio 1.1 Construction Logic and Historical Performance of Shenwan Goldsmith Growth Portfolio - The Shenwan Goldsmith Growth Portfolio relies on the prediction of listed companies' future high - performance growth rates. It first selects stocks with the top half of the current one - year profit forecast growth rate from the stocks covered by analysts in the whole market. Then, in October, it eliminates samples with negative cumulative profit growth rates in the first three quarters. Finally, it uses the analyst consensus expectation change factor to select 50 stocks [4]. - The portfolio has achieved good results in predicting performance, with the median of the average net profit growth rate falling between the first and second groups of the net profit growth rate of the whole - market stocks in the following year, that is, in the top 10% - 20% of the whole market [4]. - The portfolio has distinct growth - style characteristics. It achieved returns of over 62%, 58%, and 42% in 2019, 2020, and 2021 respectively, but suffered continuous drawdowns in 2022 - 2023. It began to recover in 2024, with a return of 22.68% in 2024 and 42.85% in 2025 [8]. 1.2 Using the Industry Rotation Model to Further Improve Returns - The industry rotation model with offensive characteristics in the bull market environment can be used to enhance the return elasticity of the growth portfolio. The Shenwan Goldsmith Industry Rotation Model uses fundamental, capital, and technical factors. It also differentiates the handling of congestion and convergence according to momentum - dominant and non - dominant sectors, especially emphasizing the use of momentum [12]. - The Shenwan Goldsmith Industry Rotation Model's long - only portfolio has a relatively stable excess return compared to the average of all industry indices, and its stability can be used to continuously improve the portfolio's performance [15]. 2. Nonlinear Tilt - Weighted to Enhance Portfolio Return Elasticity 2.1 Nonlinear Tilt - Weighted Method - The linear tilt - weighted method has limited impact on the portfolio's return. Therefore, a nonlinear tilt - weighted method is adopted, which over - allocates more to industries with high scores and under - allocates more to industries with low scores, effectively utilizing the information of the industry rotation model [21]. 2.2 Portfolio Performance Improvement - After weight tilting, the portfolio's return is effectively improved. The excess return of the new tilted portfolio compared to the equal - weighted portfolio is relatively stable, indicating that the return improvement is not achieved at the cost of sacrificing return stability [25][27]. 2.3 Statistical Information such as Annual Performance - Except for 2019, the returns of the tilted portfolio have increased in other years. The returns in 2020 and 2021 have both increased to over 60%, and the drawdowns in 2022 and 2023 have decreased. The return elasticity has been significantly enhanced [34]. - The volatility and maximum drawdown of the tilted portfolio are similar to those of the equal - weighted portfolio. The annualized return of the tilted portfolio has further increased, the volatility has slightly increased, and the maximum drawdown has decreased, resulting in a significant improvement in the Sharpe ratio and Calmar ratio [36]. - After weight tilting, the maximum weight of individual stocks can rise to 4%, and the minimum weight can fall to around 0.2%. The upward and downward adjustment ratios are basically symmetrical [38]. 3. Summary - Based on the previous growth portfolio, the report uses the industry rotation model to improve the return. Considering that the linear tilt has limited impact on the portfolio, a nonlinear tilt - weighted method is adopted [41]. - After weight tilting, the portfolio's return has increased in most years, and the overall return has been improved. The excess stability compared to the old portfolio is at a good level, meaning that the return improvement is not achieved by amplifying volatility [42].
