Industry Investment Ratings - Two-olefin: ★☆☆ [1] - Plastic: ★☆☆ [1] - Polypropylene: ★☆☆ [1] - Pure benzene: ★☆☆ [1] - Styrene: ★☆☆ [1] - PTA: ★★★ [1] - Ethylene glycol: ★☆☆ [1] - Short fiber: ★★★ [1] - Bottle chip: ★☆☆ [1] - Methanol: ★☆☆ [1] - Urea: ★☆☆ [1] - PVC: ★☆★ [1] - Caustic soda: ★★★ [1] - Soda ash: ★★★ [1] - Glass: ★★★ [1] Core Views - The futures of olefins and polyolefins declined. Propylene prices were supported, while plastics and polypropylene faced supply pressure and weakening demand but had a technical rebound need [2]. - Overseas pure benzene rebounded, but the domestic market faced pressure. Styrene maintained a tight balance with high port inventory but a de - stocking expectation [3]. - PX supported PTA, but PTA faced weakening demand. Ethylene glycol had supply growth pressure and a bearish outlook. Short fiber and bottle chip faced demand weakening [5]. - Methanol was weak due to high inventory and weak demand. Urea might be strong before the Indian tender but could decline later [6]. - PVC continued to decline with high supply and low demand. Caustic soda was in a downward trend with high supply and insufficient demand [7]. - Soda ash declined with a long - term oversupply. Glass continued to decline with high intermediate inventory [8].
