Report Summary 1. Report Industry Investment Rating - The mid - term outlook for the industry is "oscillating". Specific ratings for each variety are as follows: - Steel: Oscillating [7] - Iron ore: Oscillating [7] - Scrap steel: Oscillating [7] - Coke: Oscillating weakly [7] - Coking coal: Oscillating weakly [11] - Glass: Oscillating weakly [12] - Soda ash: Oscillating weakly [12] - Silicomanganese: Oscillating [13] - Ferrosilicon: Oscillating [14] 2. Core View of the Report - Overall, the macro - positive sentiment and coking coal news catalyzed a strong rebound after the previous price decline. The steel inventory is in a destocking state, and the iron ore supply - demand is in a tight balance, leading to more optimistic voices in the market. However, the domestic construction and manufacturing industries are about to enter the off - season, and the "rush to export" is also under - performing, with limited demand growth. So the rebound height is still limited, and attention should be paid to subsequent policy guidance [5]. 3. Summary by Directory Iron Element - Supply: Overseas incremental release is lower than expected, with a year - on - year decline in cumulative shipments throughout the year, and the new project ramp - up has slowed down, reducing the annual increment [2]. - Demand: Steel mills' profitability is stable, and hot metal production has slightly decreased, expected to remain at a high level in the short term. Under the tight supply - demand balance, the inventory accumulation pressure before September is small, and the real supply - demand contradiction is not prominent. The iron ore price is expected to oscillate in the short term [2]. Carbon Element - Coking Coal - Supply: Although there are expectations of supply tightening due to safety accidents in Shanxi and the news of Mongolia's coal export tariff increase, currently, most coal mines in the production area are operating normally, and the coking coal output remains high. The news of Mongolia's export tax rate change is unconfirmed, and the port clearance continues at a high level, so the overall supply is still loose [3]. - Demand: Coke production remains high but is expected to decline due to increased inventory pressure and shrinking coking profits. During the price cut cycle, coke enterprises' enthusiasm for raw material replenishment decreases, increasing the upstream inventory pressure of coking coal. Overall, the coking coal supply - demand remains loose, and the price lacks upward momentum [3]. - Coke: Steel mills have initiated the third round of price cuts. The supply is stable, but the demand is weakening due to the decline in hot metal production and the approaching off - season of steel consumption. With the continuous decline of coking coal prices and weakening demand, the coke price is expected to be weak in the short term [10]. Alloys - Silicomanganese: The market sentiment is cautious. The cost of manganese ore is under pressure as the south32 Australian ore is arriving at the port this week. The domestic market has not reacted significantly to Gabon's ban on manganese ore exports starting in 2029. The supply is expected to increase slightly, and the demand is weak due to the off - season. The price is expected to oscillate in the short term [13]. - Ferrosilicon: The supply has increased slightly, and the downstream is in the off - season with a strong willingness to destock. The demand is expected to weaken further, and the cost may still have a negative impact. The price is expected to be under pressure in the short term [14]. Glass - Demand: In the off - season, the demand is declining, and the deep - processing demand is still weak year - on - year. - Supply: There are both cold - repair and restart plans, and the supply pressure remains. The upstream inventory is accumulating, and the mid - stream inventory is decreasing. The price is expected to oscillate weakly in the short term, and attention should be paid to the price cuts of Hubei manufacturers [5]. Soda Ash - Supply: The over - supply situation remains unchanged, and the maintenance is gradually resuming. - Demand: The heavy - soda demand is expected to be mainly for rigid procurement, and the growth of photovoltaic glass daily melting may not be sustainable. The price is expected to oscillate weakly in the short term and decline in the long term [5].

Group 4: Rubber Report Industry Investment Rating Not provided. Core Viewpoints In the short - term, the macro - economic recovery drives the rubber price to rebound. However, with the expectation of increasing supply and weakening demand, the rubber price is expected to remain weak. It is recommended to short on rebounds above 14000. Attention should be paid to the raw material supply in each production area and macro - event disturbances [5]. Summary by Directory - **Spot Prices and Basis**: The price of Yunnan state - owned whole - latex rubber increased by 1.12%, and the basis increased by 101.96%. The price of Thai standard mixed rubber decreased by 0.74% [5]. - **Inter - month Spreads**: The 9 - 1 spread decreased by 5.39%, the 1 - 5 spread decreased by 40.00%, and the 5 - 9 spread increased by 6.40% [5]. - **Fundamental Data**: In April, the production of Thailand, Indonesia, and India decreased, while China's production increased.

1. Report Industry Investment Rating - The mid - term outlook for the black building materials industry is "oscillating" [5][9][16] - Specific product ratings: - Steel: oscillating [7] - Iron ore: oscillating [7][9] - Scrap steel: oscillating [8] - Coke: oscillating weakly [8][10] - Coking coal: oscillating weakly [11][13] - Glass: oscillating weakly [12] - Soda ash: oscillating weakly [12][14] - Ferrosilicon: oscillating [15][16] - Silicomanganese: oscillating [14] 2. Core View of the Report - The expectation of supply contraction in the coking coal market has increased, and the prices of the black series have rebounded as a whole. However, due to the approaching off - season of domestic construction and manufacturing industries and the under - expected "rush for exports", the demand is difficult to increase, so the rebound height is limited. Attention should be paid to the subsequent policy orientation [2][3][5] 3. Summary by Relevant Catalogs 3.1 Overall Black Building Materials Market - **Supply and demand situation**: The domestic demand is seasonally weakening, and the "rush for exports" in the manufacturing industry is under - expected. The off - season trend remains unchanged. Electric furnaces and some blast furnaces have started to make losses, and the molten iron is expected to decline, but the overall profitability provides some support to the cost side [2][3][5] - **Rebound driver**: Low valuation combined with news speculation brings rebound drive, but the height is limited [2][3][5] 3.2 Specific Product Analysis 3.2.1 Steel - **Core logic**: The prices of raw materials rebounded, but the fundamentals changed little. The domestic policy is in a vacuum period, and there are still expectations of tariff risks. The demand for the five major steel products rebounded this week, but the domestic demand expectation is still weak. The molten iron is at a high level, and the steel output has increased. The overall supply - demand fundamentals have improved this week, and the inventory has decreased, but the falling raw material prices and the pessimistic expectation of domestic demand suppress the futures price [7] - **Outlook**: The fundamentals have improved this week, but the expectation is still pessimistic, and the raw material prices are weakening. It is expected that the steel price will oscillate in the short term [7] 3.2.2 Iron Ore - **Core logic**: The overseas supply increment is lower than expected, the cumulative annual shipment has decreased year - on - year, and the new project ramp - up has slowed down. The steel enterprises' profitability and order status are still good, and the molten iron is expected to remain at a high level. The supply - demand is in a tight balance, and the inventory accumulation pressure before September is small. Affected by the coking coal news, the iron ore price has also increased slightly [3][7] - **Outlook**: If the molten iron can stop falling around 240,000 tons per day as expected and the macro sentiment warms up, the price is expected to continue to rise, but the upside space is limited, and the 09 contract will oscillate in a wide range [7] 3.2.3 Scrap Steel - **Core logic**: After the holiday, the arrival volume is low, and the electric furnace valley - electricity is in a loss state. The apparent demand for rebar has rebounded slightly, and the total inventory has decreased slightly. The supply of scrap steel is tight, and the demand has decreased. The inventory in the factory has increased slightly [8] - **Outlook**: The market is pessimistic about the off - season demand, the finished product price is under pressure, and the electric furnace valley - electricity loss has intensified. It is expected that the price will oscillate in the future [8] 3.2.4 Coke - **Core logic**: The expectation of coking coal supply tightening has increased, but the actual supply - demand remains loose. The supply of coke is stable, but the inventory has accumulated. The demand is weakening, and the cost support is insufficient [8][10] - **Outlook**: The coking coal price is continuously falling, and the demand is weakening. It is expected that the short - term upward trend of the futures price will be difficult to sustain [10] 3.2.5 Coking Coal - **Core logic**: The expectation of supply tightening has increased due to safety accidents in Shanxi and the news of Mongolia's coal export tariff increase. However, the actual supply is still loose, the demand is expected to decline, and the upstream inventory pressure is increasing [4][11] - **Outlook**: The supply - demand of coking coal remains loose, and the high inventory restricts the upside space of the futures price [11] 3.2.6 Glass - **Core logic**: The off - season demand decline is not obvious, the deep - processing demand has improved month - on - month but is still weak year - on - year. The daily melting volume is stable, and the price is low, which inhibits the resumption of production. The inventory in the upstream is expected to increase, and the inventory in the middle reaches has decreased. The futures price oscillates due to news and sentiment [12] - **Outlook**: The actual demand is under pressure in the off - season, the futures price is at a discount to the spot price. The price cut of Hubei's spot goods leads the futures price to decline. It is recommended to pay attention to the price - cut range of Hubei's manufacturers, and the short - term view is oscillating weakly [12] 3.2.7 Soda Ash - **Core logic**: The supply capacity has not been cleared, and the supply pressure still exists. The demand for heavy soda ash is expected to maintain rigid procurement. Affected by the coal market news, the price has fluctuated, and the long - term oversupply pattern remains unchanged [12][14] - **Outlook**: The oversupply pattern remains unchanged, and the maintenance is gradually resuming. It is expected to oscillate weakly in the short term, and the price center will decline in the long term [14] 3.2.8 Ferrosilicon - **Core logic**: Affected by the improved sentiment in the black sector, the futures price of ferrosilicon has rebounded from a low level. The supply has increased slightly, but the demand is weakening, and the market sentiment is cautious [15] - **Outlook**: The supply - demand of ferrosilicon is weak, and the demand is expected to continue to weaken. The cost may still have a drag effect. It is recommended to pay attention to the steel procurement and production situation, and the futures price is expected to oscillate in the short term [15] 3.2.9 Silicomanganese - **Core logic**: Affected by the improved sentiment in the black sector, the futures price of silicomanganese has rebounded from a low level. The cost is weakly stable, the supply is increasing, and the demand is weakening [14] - **Outlook**: The supply of silicomanganese is expected to increase, and the demand is weakening. The supply - demand is becoming looser. The manufacturers are reluctant to sell due to cost inversion. It is expected that the futures price will oscillate in the short term [14]

Report Summary 1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Core Viewpoints - For soda ash, although the overall profit on the supply - side has declined, natural soda ash projects maintain high profits. Traditional backward - capacity maintenance has intensified, and the expansion of natural soda ash project capacity has led to an increase in production and capacity utilization, resulting in significant supply pressure. On the demand side, while futures and spot traders are active and restocking is sufficient, the decline in soda ash spot prices is expected to lead to a slowdown in demand and a decrease in the de - stocking speed. The main downstream industries of soda ash, such as float glass and photovoltaic glass, are not optimistic. Therefore, it is recommended to go short on the soda ash main contract after a rebound [2]. - For glass, on the supply side, the resumption of production lines in some areas has increased the weekly output, but the overall industry profit is poor, and the willingness of enterprises to support prices is limited, so the subsequent resumption of production may decline. On the demand side, the current real - estate situation is not optimistic, and demand will weaken further in the traditional off - season. Downstream deep - processing orders are unstable, and purchases are mainly for rigid needs. The increase in the inventory of automobile glass factories cannot offset the weak demand related to real estate, and photovoltaic glass also faces inventory pressure. It is expected that there is still upward momentum in the short term, and it is recommended to go short after a short - term rebound [2]. 3.
