产需修复持续性有待观察——11月PMI点评
Changjiang Securities· 2025-12-01 23:30
1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report In November 2025, the manufacturing PMI showed a marginal improvement with synchronized recovery in production and demand and accelerated destocking, but the asymmetric recovery of raw material and finished product prices may still restrict corporate profit repair, and the sustainability of external demand contribution remains to be verified. The decline in service - sector sentiment indicates that the resilience of domestic demand also needs to be observed. The bond market has adjusted, and the impact of PMI data is expected to be limited. It is recommended to allocate 10 - year Treasury bonds with a taxable coupon yield above 1.8% when there are adjustments [2]. 3. Summary by Related Catalogs Manufacturing PMI - **Overall situation**: In November 2025, the manufacturing PMI was 49.2%, up 0.2 pct from the previous month, still seasonally weak but with marginal improvement. Production, procurement, and import indices on the supply - side increased, and new order and backlog order indices on the demand - side rose. Inventory destocking accelerated, and some predictive indicators showed improved supply - demand relationships [5][9]. - **External demand contribution**: The new export order index rose 1.7 pct to 47.6%, and the new export order indices of four major manufacturing industries and large, medium, and small enterprises all increased. However, the asymmetric recovery of raw material and finished product prices may pressure corporate profit repair [9]. - **Enterprise size and industry differences**: Small and medium - sized enterprises' sentiment improved, especially small enterprises which rose 2 pct to a nearly 6 - month high of 49.1%, while large enterprises' sentiment declined 0.6 pct to 49.3%. High - tech manufacturing with a high proportion of small and medium - sized enterprises remained in expansion, while the sentiment of equipment and consumer goods manufacturing declined, and their production sides may be stronger than the demand sides [9]. Non - manufacturing PMI - **Overall situation**: The non - manufacturing business activity index was 49.5% in November 2025, down 0.6 pct from the previous month, the first time below the boom - bust line since 2023. The service - sector sentiment was dragged down by factors such as the fading holiday effect, while the construction industry's sentiment improved [5][9]. - **Sub - item structure**: The inventory and new order indices of non - manufacturing declined, while the new export order index rose. The sales price and input price indices increased for two consecutive months. In the service sector, the financial industry and some new - energy industries showed good performance. The construction industry's business activity index increased, possibly boosted by financial activities and policy support [9]. Investment Suggestion The bond market has adjusted, and the impact of PMI data is expected to be limited. It is recommended to allocate 10 - year Treasury bonds with a taxable coupon yield above 1.8% when there are adjustments [2][9].

海外降息预期强化,钢价怎么走?
Changjiang Securities· 2025-12-01 11:42
Investment Rating - The industry investment rating is Neutral, maintained [9] Core Views - The expectation of overseas interest rate cuts is strengthening, which may lead to a corresponding adjustment in domestic monetary policy. The reserve requirement ratio is expected to trend downward, positively impacting short-term steel prices. Historical data shows that after 10 instances of reserve requirement cuts since 2020, the average increase in rebar prices was 20, 42, 45, 41, and 26 CNY/ton in the first five trading days post-cut, indicating a strong likelihood of price increases in the short term [2][6]. Summary by Sections Supply and Demand Dynamics - Steel inventory is being reduced smoothly, and there is a positive outlook for the real estate sector, leading to a slight increase in steel prices. However, the profitability of steel companies has not shown significant improvement due to sustained high prices of iron ore and coke. It is expected that steel production will continue to decline as companies proactively reduce inventory and conduct maintenance towards the end of the year. Demand may also weaken seasonally [4][5]. - The apparent consumption of five major steel products increased by 0.12% year-on-year but decreased by 0.81% month-on-month. The production of five major steel products decreased by 2.20% year-on-year but increased by 0.74% month-on-month, with daily molten iron production dropping to 2.3468 million tons [4][5]. Price Trends - Recent price trends show that Shanghai rebar has risen to 3,260 CNY/ton, an increase of 30 CNY/ton, while hot-rolled steel has reached 3,270 CNY/ton, up by 20 CNY/ton. The estimated profit for rebar is -134 CNY/ton, with a lagging cost profit of -99 CNY/ton [5]. Long-term Outlook - The renewed overseas interest rate cut cycle is expected to stabilize medium-term demand expectations for manufacturing. Although direct export demand for steel is limited, there is significant indirect demand through downstream sectors such as machinery, automotive, and home appliances. If overseas manufacturing recovers, it could stabilize steel manufacturing demand. The demand side for steel is expected to remain stable in 2026, driven by reduced production and improved cost structures [7][8].

The growth in inventory was mainly due to increases in Arcteryx inventory and exchange rate effects, with expectations for inventory growth to normalize by the second half of 2026 [10]. - The company raised its full-year guidance, projecting FY2025 revenue growth of 23% to 24% (previously 20% to 21%).
