丨证券研究报告丨 行业研究丨行业周报丨钢铁 [Table_Title] 回顾反内卷政策，2026 年钢铁分级管理怎么走？ 报告要点 [Table_Summary] 回顾 2025 年，反内卷无疑是钢铁行业最受关注的交易主线。作为低价内卷的典型行业，也是 过往供改的重点行业，市场期待随着反内卷的渐进深化，钢铁的供给侧具有出清的预期。尽管 2025 年暂未看到反内卷的具体举措落地，但通过对重点政策的系统性梳理，可以清晰地理出 "分级管理、扶优劣汰"的调控思路。随着 2026 年政策抓手和配套政策的进一步完善，行业 有望迎来供给侧出清的机遇。考虑到近年来产量压减政策的延续性和"扶优劣汰"的思路，不 规范企业或具有更大的产量压减幅度，从而具有市场化出清的预期。 分析师及联系人 [Table_Author] 王鹤涛 赵超 易轰 吕士诚 SAC：S0490512070002 SAC：S0490519030001 SAC：S0490520080012 SAC：S0490525080005 SFC：BQT626 SFC：BUY139 SFC：BUZ394 请阅读最后评级说明和重要声明 %% %% %% %% research ...

- The report focuses on the performance of stock selection factors in 2025, highlighting the effectiveness of factors such as transaction count, liquidity, crowding, price stability, and reversal in stock selection across the market [1][5][15] - Factors are categorized into two main groups: volume-price factors and growth factors. Volume-price factors are further divided into two representative categories: price stability and reversal, while liquidity, crowding, and transaction count serve as average representatives of volume-price factors [6][24] - The construction of major factors involves market capitalization and industry neutrality, outlier removal, and standardization, followed by equal-weight synthesis into major factors [13] - Sub-factors are detailed with their calculation methods, such as residual volatility derived from the Fama-French three-factor model regression residual volatility, turnover rate variation coefficient calculated as turnover rate divided by the standard deviation over the mean, and entropy of transaction volume proportion using the entropy formula [13] - The report provides statistical data on the performance of major factors, including IC, ICIR, excess returns, maximum drawdowns, IR, long-short returns, long-short maximum drawdowns, and long-short Sharpe ratios. For example, liquidity factor achieved an IC of 9.72%, ICIR of 1.08, excess return of 23.67%, and IR of 3.43 [15][16] - Sub-factors with notable performance include short-term reversal (IC 6.27%, ICIR 1.21, excess return 4.86%), residual volatility (IC 9.42%, ICIR 1.22, excess return 1.53%), and turnover rate (IC 10.75%, ICIR 1.29, excess return 17.46%) [17] - The report highlights the time-series performance of factors, noting that the main profit periods for all factors were concentrated between January and November 2025, with significant drawdowns occurring between September and December 2025. Growth, SUE, and price stability factors had lower profit levels and higher drawdowns, while liquidity factors had higher profit levels and higher drawdowns [19][20][23] - The correlation analysis of excess returns among factors shows that price stability has a high correlation with other factors, while reversal has a low correlation with other factors. Liquidity, crowding, and transaction count factors exhibit low mutual correlation [21][24]

Investment Rating - The investment rating for the industry is "Positive" and maintained [8]. Core Insights - The report analyzes how Wuliangye navigated through a pricing crisis from 2013 to 2015, facing challenges such as declining demand, high inventory, severe price inversion, and low willingness of distributors to make payments. Various strategies were employed to stabilize market prices, but in 2014, the pricing issue persisted. A reasonable adjustment of payment prices was identified as the first step to resolving the price inversion, but comprehensive supply-demand adjustments, including inventory control and marketing reforms, were necessary for long-term solutions [2][4][13]. Summary by Sections 2013: Price Increase Amidst Challenges - In 2013, Wuliangye attempted to maintain brand strength by raising the factory price to 729 yuan, but due to weak demand, they provided a rebate of 70 yuan to distributors, effectively lowering the price to 659 yuan. However, the average market price remained around 580 yuan, leading to reduced payment willingness from distributors [5][15]. 2014: Diverse Subsidy Policies but Continued Price Inversion - In 2014, Wuliangye implemented various measures to address the price inversion, including a dynamic price protection mechanism and a focus on core distributors. Despite these efforts, reliance on core distributors limited the ability to fully develop channel resources. The factory price was directly lowered to 609 yuan in May, but further increases in quotas led to additional price declines, indicating that merely increasing subsidies was insufficient to resolve the issue [6][19]. 2015: Clear Inventory Control and System Reform - In 2015, Wuliangye emphasized inventory control as a key strategy, stating that the total supply would not increase compared to 2014. Internal reforms were initiated to localize marketing personnel and marketize sales staff compensation, transforming them into market-oriented roles. A comprehensive market management system was established, leading to successful price stabilization during peak sales periods in 2015 [7][21].
