1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The rebound space of soda ash and glass is limited due to market sentiment disturbances. For soda ash, the futures price has shifted upward due to macro - disturbances and maintenance expectations. Although the high supply currently exerts pressure on prices, there is an expectation of marginal improvement in May. For glass, the sales - to - production ratio has rebounded, but the pessimistic market expectation remains unchanged [1][4][54]. 3.
