1. Report Industry Investment Ratings - No industry investment ratings are provided in the report. 2. Core Views - The fundamentals of the glass industry are currently weak in the short - term, and attention should be paid to the demand during the peak season. For the soda ash industry, the fundamentals have not improved, and it will experience short - term fluctuations [1]. - For soda ash, the industry pattern has not significantly improved. Supply - side production has rebounded and remained at a high level, while demand is mostly for rigid needs. Short - term upstream inventory has increased again, and the absolute inventory level is high, which is difficult to provide sufficient support based on fundamentals. Attention should be paid to market sentiment changes and coal price fluctuations. For glass, the fundamentals have deteriorated in the short - term, and there have been frequent regulatory actions by the exchange recently. Short - term risks should be vigilant, and attention should be paid to the replenishment intensity in late August [4][36]. 3.
