Report on Industrial Silicon 1. Investment Rating Not provided. 2. Core View The industrial silicon futures fluctuated strongly. Although the demand is increasing, the supply is increasing even more. Pay attention to the change of the spot - futures arbitrage window. The increase in the production of polysilicon and silicone is beneficial to the demand for industrial silicon and inventory digestion, as well as the arbitrage of buying industrial silicon and shorting polysilicon. But if the demand weakens again, the inventory pressure will suppress the price of industrial silicon [6]. 3. Summary by Directory - **Spot Price and Main Contract Basis**: On June 24, the price of East China oxygen - passing S15530 industrial silicon remained unchanged at 8,150 yuan/ton.

Pay attention to the production release of polysilicon. If there is continuous resumption of production, the price will be under pressure. Hold short positions cautiously [7]. 3. Summary by Directory - **Spot Price and Basis**: On June 24, the average prices of N - type re -投料, P - type cauliflower - like material, and N - type granular silicon remained unchanged. The N - type material basis (average price) decreased by 470 yuan/ton to 3,415 yuan/ton, with a 12.10% decrease; the cauliflower - like material basis (average price) decreased by 470 yuan/ton to 9,415 yuan/ton, with a 4.75% decrease [7]. - **Futures Price and Inter - month Spread**: The PS2506 contract increased by 470 yuan/ton to 31,085 yuan/ton, with a 1.54% increase.

1. Report Industry Investment Ratings No relevant content provided. 2. Core Views of the Reports Natural Rubber - In the context of expected supply increase and weak demand, the subsequent rubber price is expected to remain weak. Hold the short position at 14,000 and monitor the raw material supply in each production area and macro - event disturbances [2]. Industrial Silicon - In June, industrial silicon still faces a weak fundamental situation of oversupply, and the price remains under pressure. Recently, the rebound in coal prices brings an expectation of rising raw material prices, which supports the price, and the price may fluctuate at a low level [4]. Polysilicon - The fundamentals have not significantly improved, and the atmosphere at the Shanghai PV exhibition is bearish. However, due to the low price, hold short positions cautiously and pay attention to the pressure level around 35,000 yuan/ton. If the polysilicon production increases, it is beneficial for the arbitrage of buying industrial silicon and shorting polysilicon [5]. Glass and Soda Ash - For soda ash, the excess pattern is obvious, and there will be further profit - reduction. After the photovoltaic rush - installation, the growth of photovoltaic capacity has slowed down, and the overall demand has not increased significantly. After the maintenance, inventory accumulation may accelerate. - For glass, it still faces over - supply pressure in the future, and the industry needs capacity clearance. The 09 contract fluctuates around 1000 points, and a short - term bearish strategy can be considered [6]. 3.

Group 2: Glass and Soda Ash Report Industry Investment Rating Not provided Core View - **Soda Ash**: In the short term, the decline of the futures market has slowed down, and it is more likely that the inventory will remain flat.
