1. Report Industry Investment Ratings No relevant information provided in the reports. 2. Core Views of the Reports Glass and Soda Ash - Yesterday, the soda ash futures market sentiment weakened, with the 09 contract dropping about 30 points. Although the overall market sentiment had improved earlier, the supply - demand pattern of soda ash remains in surplus, with continuous inventory accumulation. It is recommended to watch for opportunities to short on rebounds [1]. - The glass futures market sentiment declined yesterday, while the spot market remained strong. Currently, it is the off - season, and the industry needs capacity clearance. It is advisable to wait and see for now [1]. Logs - Yesterday, the log futures market fluctuated slightly stronger. The market is in a situation of weak supply and demand due to the off - season for demand and seasonal reduction in supply from New Zealand. The 09 contract is expected to fluctuate weakly, and attention should be paid to market sentiment and policy expectations [2]. Industrial Silicon - The spot price of industrial silicon increased by 150 - 200 yuan/ton, and the futures price rose by 90 yuan/ton. The supply is expected to increase. In the short - term, the price will fluctuate strongly, but attention should be paid to the risk of price decline due to the increase in warehouse receipts [3]. Polysilicon - The polysilicon spot price stabilized, and the futures price increased. There is still room for the futures price to catch up with the spot price. The market has a wait - and - see attitude, and there are both positive and negative factors. Attention should be paid to the risk of price decline [4]. Natural Rubber - The natural rubber price rebounded due to macro - sentiment, but the fundamental situation is still weak. It is recommended to short at the price range of 14,000 - 14,500 yuan/ton, and pay attention to raw material supply and US tariff changes [5]. 3.

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.
