1. Report Industry Investment Ratings No investment ratings are provided in the reports. 2. Core Views - **Natural Rubber**: Short - term macro warming drives rubber price rebound, but under the expectation of increasing supply and weak demand, the rubber price is expected to remain weak. It is recommended to short on rebounds above 14,000. Attention should be paid to the raw material volume in each production area and macro events [1]. - **Industrial Silicon**: The demand for industrial silicon is expected to pick up, but the supply increase is larger. The inventory is expected to accumulate, and the price is under pressure. However, the rebound of coal prices provides some support, and the price may fluctuate at a low level [3]. - **Polysilicon**: In June, there is no obvious improvement in fundamentals. There is a risk of inventory accumulation, and the cost support may decline.

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.

Polysilicon Industry Report Industry Investment Rating Not mentioned in the report. Report's Core View In June, the polysilicon market is expected to remain in a situation of weak supply and demand. If there is no further production cut, there is a risk of inventory accumulation. However, due to the expected contraction of the supply side, if the production decreases and the supply - side pressure eases, the inventory is expected to be gradually reduced. Attention should be paid to the support in the range of 33,000 - 34,000 yuan/ton [4].

Report Summary 1. Investment Rating No investment rating for the industry is provided in the report. 2. Core Views - The pessimistic sentiment in the black commodities market is receding, leading to a bottom - up rebound. The glass and soda ash markets show a divergence between futures and spot prices due to cautious downstream procurement. The double - silicon market has a stabilized sentiment with alloy prices oscillating [1][3]. - Glass has a severe supply - demand contradiction with high inventory and lack of substantial production cuts. Soda ash faces continuous supply - demand surplus pressure and strong de - stocking pressure [1]. - For silicon manganese, low production due to profit issues and high inventory suppress prices, while manganese ore cost provides support. Silicon iron production is at a low level, but demand has some resilience, and short - term prices are affected by costs [3]. 3. Summary by Related Catalogs Glass and Soda Ash - **Market Analysis** - Glass: Futures rebounded significantly yesterday, but spot trading was weak with mainly rigid demand procurement and low speculative sentiment. Soda ash: Futures rose sharply following black commodities, while downstream procurement was cautious with mainly rigid demand replenishment [1]. - **Supply - Demand and Logic** - Glass: The supply - demand contradiction is severe, high inventory suppresses prices, and there is no substantial production cut. Long - term losses are needed to clear excess capacity, and later changes in production lines and raw material prices should be monitored. Soda ash: With new production projects coming online, the supply - demand surplus persists, and there is strong de - stocking pressure. Prices will be under pressure until the surplus situation eases, and attention should be paid to intermittent production line maintenance and new production [1]. - **Strategy** - Glass: Oscillating. Soda ash: Oscillating. No cross - period or cross - variety strategies are recommended [2]. Double - Silicon (Silicon Manganese and Silicon Iron) - **Market Analysis** - Silicon Manganese: Futures oscillated and rebounded with black commodities yesterday. The spot market was stable, and factories were reluctant to sell at low prices. The price in the northern and southern markets was 5400 - 5500 yuan/ton. Silicon Iron: Futures oscillated. The cash - inclusive ex - factory price of 72 - grade silicon iron in the main production areas was 5150 - 5200 yuan/ton, and the price of 75 - grade silicon iron was 5750 - 5850 yuan/ton [3]. - **Supply - Demand and Logic** - Silicon Manganese: Production is at a low level due to industry profits, iron - water production has slightly declined but remains high, and demand has some resilience. High factory inventory and registered warehouse receipts suppress prices, while low - level manganese ore port inventory has slightly increased, and falling manganese ore prices support alloy costs. Attention should be paid to the manganese ore supply side. Silicon Iron: Production has dropped to the lowest level in recent years due to enterprise losses, high iron - water maintains demand resilience, factory inventory de - stocking is weakening, downstream inventory is low, and short - term prices are affected by costs. Attention should be paid to electricity price changes and industrial policies [3]. - **Strategy** - Silicon Manganese: Oscillating. Silicon Iron: Oscillating [4].
