1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report 2.1纯碱市场 - 纯碱检修计划衔接力度略不及预期及新产能投放取得进展，产量见底回升；前期基差力度不足导致未能形成持续正反馈，当前期现优势出货，厂家间压力分化 [8][9]。 - 供应重回上行，带动库存压力回升；终端备货较充足，终端利润状况较差，驱动偏弱。但阶段性盘面贴水较大，期现大幅出货后持货减少，结合头部厂家产量负荷波动，短期可转观望 [9]。 - 策略建议：前期空头思路可阶段逢低获利，重新等待入场机会 [9]。 2.2玻璃市场 - 需求氛围弱势及部分区域受低价期现货源压制，低价区厂家降价以促出货。部分厂家据自身情况点火复产 [169]。 - 估值角度进入理想布局区间，但须等待市场情绪好转启动。后续跟踪产线变动情况，观察低价期现货源消化进度及主产区现货量价情绪变化 [169]。 - 策略建议：市场暂缺上行驱动，远月合约待情绪缓和逢低做多思路 [169]。 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - For the soda ash market, the industry conference promotes production - cut and price - support plans. Although short - term factory inventory is expected to decrease and the mid - stream may stop reducing inventory, continuous price increases are difficult. The long - term bearish trend remains, but caution is needed before the positive feedback atmosphere ends. Traders are advised to pay attention to new order transaction prices and the implementation of maintenance and price - support plans, and short - term short - covering and then short - selling at high prices are recommended after the upward sentiment calms down [8][9]. - For the glass market, from a valuation perspective, it has entered an ideal layout range, but it is necessary to wait for the market sentiment to improve. A long - position strategy for far - month contracts is recommended, and subsequent attention should be paid to production line changes, the digestion progress of low - price spot and futures sources, and the price - volume sentiment changes of spot in major production areas [173]. 3.
