1. Report Industry Investment Rating There is no information about the industry investment rating in the report. 2. Core View of the Report The domestic caustic soda plants are still in the recovery phase, with few recent shutdown plans, and the capacity utilization rate is expected to maintain an upward trend. The expected new production capacity from July to August is relatively high, and the medium - to - long - term supply pressure may increase. The price of downstream alumina has rebounded, driving an increase in the enthusiasm of enterprises for复产, and there is still some room for the alumina operating rate to rise. The off - season for non - aluminum downstream industries continues, with weak demand. In the short term, the supply - demand contradiction of caustic soda in the spot market is not significant, and the price is expected to fluctuate slightly. Attention should be paid to the support around 2470 and the pressure around 2700 on the daily K - line of SH2509 [1]. 3.

Report Summary 1. Report Industry Investment Rating - Not provided in the content 2. Core View of the Report - SH2509 fell 2.10% to close at 2466 yuan/ton. The supply - side saw new device overhauls in Central and East China last week and increased load in some devices in South and North China. The caustic soda capacity utilization rate decreased by 0.1% to 80.4% with little change. On the demand side, the alumina start - up rate increased by 1.72% to 83.28% last week, and the average profit of alumina was 300.3 yuan/ton. The viscose staple fiber start - up rate increased by 2.63% to 77.80% last week, and the printing and dyeing start - up rate decreased by 1.29% to 59.9%. In terms of inventory, the liquid caustic soda factory inventory decreased by 2.58% to 37.43 tons last week with little inventory pressure. The planned overhaul capacity of caustic soda in July decreased. Recently, the downstream start - up of liquid chlorine increased, and the inverted situation of liquid chlorine in Shandong was alleviated, which repaired the chlor - alkali profit and opened up the room for the increase of the caustic soda start - up rate. There are many stop and restart devices this week, and the capacity utilization rate is expected to rise slightly. The non - aluminum off - season demand is weak, and downstream purchases are mainly for rigid needs. In the short term, SH2509 is expected to show a volatile trend, and the daily K - line should pay attention to the support around 2420 [3]. 3.
