1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report - In the context of uncertain Fed rate - cut amplitude next year, significant global economic and geopolitical variables, it's difficult for liquidity to drive a major upward trend. The AI infrastructure faces over - investment doubts, and the AI, lithium - battery, and anti - involution sectors are waiting for certain developments. From a seasonal perspective, high - dividend sectors are expected to have a good performance at the end of the year. Overall, the equity market may enter a wide - range oscillation state, waiting for the spring rally. [2][17] - In the convertible bond market, the capital flow in November had a great impact on the market. The share of convertible bond ETFs showed a "down - up - down" trend, which was consistent with the overall market valuation trend. Due to unclear equity expectations and poor overall cost - effectiveness of convertible bond assets, the premium rate is vulnerable, and the operation of convertible bonds is difficult. [2][17] - For relative - return investors, it is recommended to allocate a small and balanced position in non - callable, high - quality equity - linked convertible bonds with suitable premium rates. For absolute - return investors, it is recommended to focus on convertible bonds below 130 yuan with high odds. [2][17] 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - In 2026, the macro - atmosphere is generally warm. The Fed's interest - rate cut cycle is in the "second half", and China's policies are expected to be positive as it is the beginning of the "15th Five - Year Plan". However, demand still lacks highlights, and supply becomes the key variable. Raw materials face downward pressure, steel prices will fluctuate within a range, and there will be a differentiation between finished products and raw materials [1][2]. 3. Summary According to the Directory 2025 Review 1.1 Market Review - Steel prices fluctuated in a "down - up - down" pattern with a small amplitude. The first decline was due to overseas tariff policies and cost reduction, the rise in July was from anti - involution, and the second decline was from the game between strong expectations and weak reality. The spread between the high and low points of the weighted closing prices of rebar and hot - rolled coils was only about 500 yuan [5]. - The average prices of coking coal and coke dropped significantly, with an annual average decline of over 25%. The average price of iron ore decreased by 8 US dollars/ton (6.88% decline), and the average prices of rebar and hot - rolled coils decreased by about 300 yuan/ton (about 8.5% decline). The cost center of steel products moved down [9]. 1.2 Industrial Pattern - **Demand**: Domestic consumption of crude steel continued to decline, but steel and billet exports maintained high growth. From January to October, the cumulative apparent demand for crude steel decreased by 6.51% year - on - year, steel exports increased by 6.6% year - on - year, and net exports increased by 653 tons. The cumulative export of billets from January to October was 11.9 million tons, a year - on - year increase of 7.27 million tons [15]. - **Supply**: The consumption of scrap steel and the output of crude steel declined. From January to October, the cumulative year - on - year growth rates of pig iron and crude steel output were - 1.8% and - 3.9% respectively. The consumption of scrap steel decreased by 13.3% year - on - year. The output of rebar decreased by 4.8 million tons ( - 2.0% growth rate), and the output of hot - rolled coils increased by 9.8 million tons (5.30% growth rate) [19][23][27]. - **Raw Materials**: The supply of iron ore and coking coal slightly declined, and inventories decreased slightly compared to the beginning of the year. From January to October, the output of iron ore concentrate decreased by 3.70%, and imports increased by 0.62%. The supply of coking coal changed little year - on - year, with domestic production increasing by 1.17% and imports decreasing by 4.73%. The combined inventory of 247 sample steel mills and port trading mines decreased by about 10.65 million tons compared to the beginning of the year, and the coking coal and coke inventory decreased by about 5.5 million tons [31][32]. 2026 Outlook 2.1 Overseas Macroeconomy - The Fed's interest - rate cut cycle is in the "second half". After restarting rate cuts in September and October 2025, it is expected to cut rates again in March and June 2026, bringing the federal funds rate to 3% - 3.25%, providing more room and autonomy for China's monetary policy [40]. 2.2 Domestic Macroeconomy - 2026 is the beginning of the "15th Five - Year Plan", with expected positive policy tones. Boosting consumption and expanding domestic demand may be the key focus [45]. 2.3 Infrastructure Demand - Since the second half of 2025, infrastructure investment growth has declined significantly. Policy tools such as new policy - based financial instruments and increased local government debt quotas have been introduced. Policy effects may be gradually released at the end of 2025 and early 2026, and infrastructure investment is expected to remain stable in 2026 [49]. 2.4 Real Estate Demand - In 2025, real estate data continued to decline. The real estate development model is changing from an incremental to a stock market. In 2026, real estate is expected to remain weak, with an estimated 10% decline in real estate investment and a continued decline in steel consumption for real estate [54]. 2.5 Manufacturing Demand - Since the second half of 2025, the monthly investment growth rate in the manufacturing industry has turned negative, with significant industry differentiation. In 2026, manufacturing investment is still under pressure, but industry differentiation will be severe [58]. 2.6 Import and Export Demand - In 2025, despite anti - dumping and trade wars, steel exports maintained growth due to changes in export destinations and varieties. In 2026, although challenges remain, steel exports are expected to remain high due to corporate expansion overseas and adjustment of export structures [60][62]. 2.7 Supply - In 2026, policy influence on the steel supply side may increase. The "15th Five - Year Plan" emphasizes carbon emission control, and it is possible to restrict steel production through carbon emissions, which may become the main trading logic in the market [66][69]. 2.8 Raw Materials - **Coking Coal**: In 2026, domestic coking coal production may be regulated according to demand. Mongolian coking coal imports are expected to increase by about 7 million tons [74]. - **Iron Ore**: Overseas iron ore supply is expected to increase by about 72 million tons in 2026, while domestic production will remain stable. The supply of overseas iron ore projects is progressing faster than domestic ones [87]. 3. Outlook - Macroscopically, the Fed's interest - rate cut is in the "second half", and China's policies are expected to be positive. Industry - wise, demand lacks highlights, supply is the key variable, and raw materials face downward pressure. Steel prices will fluctuate within a range, and there will be a differentiation between finished products and raw materials. Opportunities in going long on steel and short on iron ore can be considered [88][89][91].

1. Report Industry Investment Rating - Not provided in the content. 2. Core Viewpoints of the Report - Black varieties, especially coking coal, are experiencing a backlash from last month's overvaluation as delivery pressure is fully manifested; the downside space for rebar and hot - rolled coils is limited, but upward movement requires policy and sentiment fermentation; the focus of iron ore is on the impact of long - term agreement negotiations on the market, showing significant box - like characteristics; the downside space for glass spot is limited, but the futures far - month prices are high, and the near - month is mainly centered around delivery, and cash - and - carry arbitrage can be considered [2]. - Total demand remains insufficient. The era of real estate has passed, infrastructure growth is restricted by various factors, and although exports are booming, they are highly uncertain due to factors like anti - dumping; anti - involution is different from supply - side reform, especially the 2016 supply - side reform in the black industry; iron ore faces significant long - term pressure, and current long - term agreement negotiations are intense; many near - month varieties are not overvalued currently, but the previous overvaluation has led to the current backlash; there are many cold repairs in the glass industry, and although there are seasonal factors, the downside space for spot is limited, but the far - month prices are still overvalued [2]. 3. Summary by Relevant Catalogs Strategy Viewpoints - Black varieties, especially coking coal, are facing a backlash from overvaluation, with delivery pressure fully shown [2]. - The downside space for rebar and hot - rolled coils is small, and upward movement depends on policy and sentiment [2]. - The key for iron ore is the impact of long - term agreement negotiations on the market, presenting box - like features [2]. - The glass spot has limited downside space, the futures far - month prices are high, near - month trading is centered around delivery, and cash - and - carry arbitrage can be considered [2]. Operating Logic - Total demand is insufficient, real estate's heyday is over, infrastructure growth is restricted, and export uncertainty is high due to anti - dumping [2]. - Anti - involution is different from supply - side reform, especially the 2016 reform in the black industry [2]. - Iron ore has significant long - term pressure, and long - term agreement negotiations are tense [2]. - Many near - month varieties are not overvalued now, but previous overvaluation causes the current backlash [2]. - There are many cold repairs in the glass industry, the spot's downside is limited due to seasonality, but far - month prices are still overvalued [2].

1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints - From the balance sheet perspective, the polysilicon market maintains a wide - balance pattern. The price support mainly comes from anti - involution expectations and price - holding by major enterprises. However, the inclusion of East Hope in the delivery list by the Guangzhou Futures Exchange may impact the pricing power of the industrial alliance. Next week's market will focus on the transfer of polysilicon pricing power. The contradiction between insufficient domestic demand and unexpected production cuts will strengthen market doubts about platform companies. The root cause lies in the long - term split pattern where high profits in the upstream lead to increased production and inventory accumulation, while low profits in the downstream result in production cuts and low inventory, without substantial improvement in inventory. High industry inventory may not have a substantial short - term impact, but if it forms a negative feedback and suppresses corporate cash flow, enterprises will have to passively reduce inventory and transfer profits to the downstream to achieve industrial chain profit balance. Investors should pay attention to enterprise warehouse receipt quotes. If the whole industry holds prices, the price difference between near - and far - month contracts will still show a BACK structure due to the scarcity of warehouse receipts. They also need to be aware of the increased volatility risk caused by the current polysilicon game [2] 3.
