Market Analysis PVC - The PVC market fluctuates with the macro - environment. Supply is abundant due to new production capacity and reduced maintenance losses. Although downstream demand has increased, the export outlook in the fourth quarter is weak, inventory is accumulating, and there is pressure on the futures price [3]. Caustic Soda - The spot price of caustic soda has been continuously decreasing. Production may increase slightly, and demand support is weakening. Attention should be paid to the downstream replenishment rhythm during the peak season and the start - up rhythm of new alumina plants in Guangxi [3].
