Report Industry Investment Rating - No relevant content provided Core Viewpoint of the Report - The PVC market is in a weak and volatile state recently. Although the termination of India's BIS policy on PVC and the possible cancellation of anti - dumping duties have some positive effects, factors such as the decline in PVC downstream demand, high inventory, new production capacity, and the traditional off - season in December lead to a weak market sentiment [1].

The lowest price was 4,311 yuan/ton, the highest price was 4,383 yuan/ton, and it finally closed at 4,328 yuan/ton, below the 20 - day moving average, with a decline of 1.39%.
