Core Viewpoint - The ABS market has continued to show weakness since early August, with some spot prices declining, reflecting a challenging supply-demand balance [1][10]. Supply Analysis - Domestic ABS industry load has increased since August, with overall load levels rising from 67% at the beginning of the month to over 71% [3]. - Weekly production is close to 140,000 tons, and inventory levels are stable at 220,000 tons, indicating a continued supply surplus [3]. - The supply side is expected to maintain a loose structure, providing limited support for ABS spot prices [3]. Cost Factors - The upstream materials for ABS have seen slight increases, but the overall impact on ABS costs remains limited [3]. - Some production facilities have reduced output, which may alleviate excess supply pressures in the short term [3]. - Downstream demand from major manufacturers remains stable, but overall cautious buying behavior persists due to ample supply [3]. Demand Analysis - The demand from downstream ABS factories has been moderate, with the market currently in a traditional off-peak season [9]. - The electrical appliance sector has reduced production, leading to further consumption declines [9]. - Geopolitical tensions in Eastern Europe have added to market caution, resulting in slow inventory turnover [9]. Market Outlook - The ABS market is expected to continue its weak consolidation trend, influenced by ongoing supply-demand imbalances [10]. - The market dynamics are unlikely to improve significantly in the short term, with prices expected to remain under pressure [10].

Report Summary 1. Report Industry Investment Rating No relevant content provided. 2. Core Views - The polyolefin market is gradually shifting to a pattern of strong supply and demand. New production capacities are being released, and maintenance devices are restarting, leading to a significant increase in production. Although social inventories are accumulating, they are still at a relatively low level compared to the same period. The start - up rate of agricultural film has improved for three consecutive weeks. Attention should be paid to the restocking rhythm [4]. - The PP market maintains a pattern of weak supply and demand. The upstream operating rate has remained at around 77% for six consecutive weeks, and downstream demand is at the transition point between the off - season and peak season. The inventory structure of the upper and middle reaches continues to diverge, with enterprises and traders' inventories accumulating, while downstream maintains low inventories. Attention should be paid to the restocking rhythm during the peak season [8]. - The propylene market may show a pattern of "both supply and demand increasing", and the price trend is more likely to be range - bound. In August, the weak pattern of the propylene market is difficult to change, and the monthly average price is expected to fluctuate around 6350 yuan/ton [11]. 3. Summary by Directory 3.1 Plastic Market - **This Week's Review**: The L2509 contract fluctuated in the range of [7251, 7344], with an opening price of 7312 yuan/ton and a closing price of 7290 yuan/ton. The market followed cost and sentiment for range - bound fluctuations. The far - month L2601 contract was firm [3][16]. - **Next Week's Outlook**: Production is expected to increase by 1.5 tons week - on - week. The import volume in June decreased by 10% month - on - month, reaching the lowest level in the past five years. Social inventories are accumulating but are still at a relatively low level. The start - up rate of agricultural film has improved for three consecutive weeks [4]. - **Strategy**: Close short positions and look for opportunities to go long on pullbacks. The L2509 contract should focus on the range of [7200 - 7350]. Hold the long LP09 arbitrage. Industrial customers can choose the opportunity to sell for hedging [6]. 3.2 PP Market - **This Week's Review**: The PP2509 contract fluctuated in the range of [7047, 7108], with an opening price of 7098 yuan/ton and a closing price of 7062 yuan/ton. The market followed macro - sentiment fluctuations, with significantly reduced volatility and a downward - shifting center of gravity. The fundamentals showed little supply - demand contradiction, with both supply and demand being weak [7][55]. - **Next Week's Outlook**: The fundamentals remain unchanged, maintaining a pattern of weak supply and demand. The upstream operating rate has remained at around 77% for six consecutive weeks, and downstream demand is at the transition point between the off - season and peak season. The inventory structure of the upper and middle reaches continues to diverge [8]. - **Strategy**: Close short positions and look for opportunities to go long on pullbacks. The PP2509 contract should focus on the range of [7000 - 7200]. Wait and see for arbitrage [9]. 3.3 Propylene Market - **This Week's Review**: The PL2601 contract fluctuated in the range of [6416, 6555], with an opening price of 6480 yuan/ton and a closing price of 6451 yuan/ton [10][83]. - **Next Week's Outlook**: A new propylene plant in Ningbo has produced products and plans to export.

The market may show a pattern of "both supply and demand increasing", and the price is expected to be range - bound [11]. - **Strategy**: Look for opportunities to go long on pullbacks at the current low price level. The PL2601 contract should focus on the range of [6300 - 6500]. Hold the long PP - PL01 spread arbitrage [12]. 3.4 Macro Review and Outlook - **This Week's Review**: The overall weekly increase was PVC > polyolefin = commodity > energy - chemical.
