GS Downgrades Yankuang Energy A to Sell; Bullish on Copper and Coal

Overview

This report provides a comprehensive update on earnings forecasts for China's commodities and agriculture sectors. The core conclusion is structural divergence: the firm is bullish on coal and copper supply-demand dynamics but believes valuations for certain stocks have already priced in optimistic expectations. The most significant action is downgrading Yankuang Energy A-shares from Neutral to Sell, citing that its share price implies coal prices far above current spot levels. Meanwhile, the report lowers earnings forecasts for steel, cement, paper, and H1 agriculture, but remains optimistic about a pig cycle reversal and phosphate fertilizer margin recovery in H2.

Core views

Coal Sector: The firm holds a positive view on coal, believing increased coal chemical demand, reduced imports, and seasonal factors support improving supply-demand dynamics. Accordingly, 2026 earnings forecasts for Shenhua, China Coal, and Yankuang are raised by 9-17%. However, regarding Yankuang Energy A-shares, the report notes the current share price implies a Qinhuangdao 5,500 kcal coal price of RMB1,244/t, significantly higher than the spot price of RMB863/t and the firm's H2 average forecast of RMB950/t. Deeming the valuation overly optimistic, the rating is downgraded to Sell with a target price of RMB19.0 (implying 24% downside). In contrast, although the TP for Yankuang Energy H-shares is raised to HKD15.0, it implies only 0% upside, maintaining a Neutral rating. Base Metals Sector: Copper is a top pick. Given expected global copper market deficits and slow mine restarts, 2026/2027 copper price forecasts are raised by 4%/14%. Earnings forecasts for Zijin Mining, Jiangxi Copper, and CMOC are raised by 1-21%, maintaining Buy ratings. For aluminum, despite currently robust industry profits, new capacity additions in H2 are expected to squeeze margins; thus, Neutral ratings are maintained for Chalco and Hongqiao Group. For gold, although short-term price forecasts are trimmed by 5%, the long-term bullish thesis remains unchanged, maintaining Buy on Zhaojin Mining. Ferrous & Building Materials Sector: Steel and cement face pressure from weak demand. Due to sluggish construction demand and delayed capacity cuts, unit gross margin forecasts for rebar and HRC are lowered. 2026 earnings forecasts for Baosteel and Magang are cut by 12-40%, while Angang is expected to see losses widen to RMB4.8bn. Cement sector earnings are also trimmed due to weak Q2 pricing, but the firm expects H2 infrastructure financing support to stabilize demand, maintaining Buy ratings on Conch Cement and CNBM. The paper industry sees earnings forecasts lowered due to persistent price declines in containerboard and cultural paper amid overcapacity; Sell ratings are maintained for Nine Dragons Paper and Sun Paper. Agriculture Sector: Hogs and fertilizers face near-term pressure but are expected to improve in H2. Affected by low hog prices in H1, 2026 earnings forecasts for Muyuan and Wens are significantly cut. However, the firm anticipates supply contraction coupled with seasonal demand will drive hog prices up in H2, maintaining Buy on Muyuan. For fertilizers, rising sulfur costs squeezed H1 margins, but profit recovery is expected post-planting season as domestic pricing controls ease; Buy is maintained on Yuntianhua. In the seed sector, Longping High-Tech earnings are cut and Sell maintained due to setbacks in its Brazil business, while DBN maintains a Buy rating leveraging its advantages in biological breeding.

Analysis framework

The report employs a dual analytical framework of 'top-down commodity price drivers + bottom-up valuation validation.' First, via a mark-to-market mechanism, full-year price assumptions for various commodities (coal, copper, steel, hogs, etc.) are updated based on actual YTD price trends, directly feeding into EPS forecasts for covered companies. Second, an 'implied commodity price' reverse-engineering method is introduced for rating decisions. Particularly in resource stock valuation, beyond absolute earnings, the current share price is used to back out the market-implied commodity price assumption, which is then compared against the firm's own spot price forecast. When the implied price significantly exceeds fundamental forecasts (as in the Yankuang A-share case), a negative rating is issued even if industry fundamentals are sound, reflecting a principle prioritizing valuation safety margins. Additionally, the report applies cyclical and seasonal analysis paradigms. In assessing agriculture and cyclical goods, it clearly distinguishes between H1 and H2 rhythms (e.g., weak H1 hog prices/high fertilizer costs vs. H2 pig cycle upturn/fertilizer profit recovery), avoiding linear extrapolation of short-term data and emphasizing inflection point opportunities.

Methodology notes

• Valuation MethodologyPB valuation

  Historical P/B vs. ROE Regression Valuation

  Target prices for resource stocks like Yankuang Energy are not set using simple P/E ratios. Instead, they are derived from a regression of the company's historical P/B ratio against ROE to determine a justified P/B multiple, which is then multiplied by the forecast ROE to arrive at the target price. This method dynamically reflects how changes in cyclical profitability support valuation.

• Event Arbitrage & Behavioral Finance

  Reverse-Engineering Implied Commodity Prices from Share Price

  An effective tool for testing valuation bubbles in resource stocks. By dividing current market cap by production volume or profit sensitivity to commodity prices, the commodity price implied by current market pricing is backed out. If this implied price far exceeds spot and forward curves, it indicates the share price has excessively priced in positives, serving as a key anchor for assessing valuation risk.

• Industry/Sector Analysis FrameworkVolume-price decomposition

  Mark-to-Market Earnings Revision Mechanism

  A core methodology in commodity research. Full-year average price assumptions are adjusted proportionally based on actual YTD spot price movements to quantitatively revise EPS. This ensures earnings forecasts promptly reflect the latest market reality rather than adhering to outdated annual outlooks.

• Cycle & Prosperity FrameworkProsperity Inflection Point Analysis

  H1/H2 Rhythm Divergence in Agriculture and Cyclicals

  When analyzing industries like hogs and fertilizers, the report focuses on identifying intra-year prosperity inflection points (e.g., 2H26E hog price rally, fertilizer profit recovery) rather than just full-year averages. This approach alerts investors to timing mismatches, preventing misleading full-year investment judgments based on weak H1 data.

Asset mapping & comparison

Impact & implications

For the coal sector, the report's view suggests investors must distinguish between 'strong industry fundamentals' and 'expensive individual stocks.' While coal supply-demand basics support earnings upgrades, valuations for some A-share leaders embed excessive premiums, making H-shares relatively better value or safer. For copper, the global supply deficit logic reinforces medium-to-long-term allocation value, with related miners likely to sustain earnings elasticity. For traditional cyclicals like steel and building materials, investors must endure a demand bottoming process in the near term; the investment window may require waiting for H2 policy implementation or tangible supply-side clearing signals. The agriculture sector offers left-side positioning opportunities, suggesting investors watch for expectation gaps regarding H2 cycle reversals during the H1 earnings trough.

Risks

• Commodity price volatility: Deviations in coal, copper, gold, and steel prices from forecasts directly impact earnings
• Macro economy and demand miss expectations: Real estate and infrastructure drag ferrous metals; weak consumption affects agriculture
• Policy and regulatory risks: Environmental/safety production restrictions, pace of new energy substitution, export tariff adjustments
• Company-specific operational risks: Geopolitics in overseas mines, delays in new project commissioning, disease outbreaks
• Valuation vs. market expectation gap: Share prices may have embedded overly optimistic or pessimistic commodity price assumptions

What to watch

• Whether Yankuang Energy A-share price corrects to a reasonable valuation range, or spot coal prices rally significantly to support current levels
• H2 hog inventory and slaughter data validating the pig cycle inflection point
• Implementation of domestic infrastructure financing and marginal changes in cement/steel demand
• Progress in global copper mine supply recovery and China copper destocking
• Correlation between coal chemical product prices and oil prices, plus progress on Yankuang's new projects
