Report Industry Investment Rating - No specific industry investment rating is provided in the report. Core Viewpoints - The demand for both PE and PP remains weak, which continues to limit their upward potential and is still constrained by supply - side pressure. The recovery of demand is slow, and the cost support is insufficient. For PE, the supply is increasing, and the demand realization rate is slow; for PP, the supply pressure is large, and the profit at a low level restricts its downward space [3]. Summary by Relevant Catalogs Market News and Important Data - **Price and Basis**: L main - contract closed at 7,169 yuan/ton (+27), PP main - contract at 6,898 yuan/ton (+21).

Market Analysis - **PE**: Supply increased as many previously - shut - down plants restarted. Demand improved slightly with pre - holiday stocking, but the demand realization rate was slow, and social inventory decreased slowly. Cost support from international oil prices was insufficient [3]. - **PP**: Supply pressure was large due to expected restart of plants, increased coal - enterprise production, and new capacity release. Demand improved marginally but slowly. Cost was supported by firm propane, and low profit limited the downward space [3]. Strategy - **Single - side**: Neutral for L and PP [4]. - **Inter - period**: L01 - L05 reverse spread; PP01 - PP05 reverse spread [4]. - **Inter - variety**: No strategy provided [4].

Report Industry Investment Rating - Unilateral: Neutral; Inter - period: 01 - 05 reverse spread; Inter - variety: None [4] Core View - Recently, the cost - end oil price has rebounded, and the external propane price has risen strongly. With the support of macro - sentiment, polyolefins have rebounded slightly with fluctuations. Some upstream petrochemical plants have shut down for maintenance, and the capacity utilization rate has decreased slightly. There is an expectation of new capacity from ExxonMobil, and Daxie Petrochemical is continuously increasing production, so the supply is still under pressure. The downstream demand is in the "Golden September" seasonal improvement stage, with the overall downstream factory operating rate rising slightly. However, the downstream mainly maintains rigid procurement, and the demand fulfillment rate is still slow. PP production profit has shrunk significantly, and the cost - end support is strong [3] Summary by Related Catalogs Market News and Important Data - **Price and Basis**: L main contract closed at 7,245 yuan/ton (+11), PP main contract at 6,982 yuan/ton (+12).

Supply is under pressure due to potential new capacity and production increases. Downstream demand is in a seasonal improvement stage, but the demand fulfillment is slow, and PP cost - end support is strong [3] Strategy - Unilateral strategy is neutral; inter - period strategy is 01 - 05 reverse spread; no inter - variety strategy [4]

Report Industry Investment Rating - Not provided Core Viewpoints - International oil prices rebounded, and propane prices continued to rise, providing cost - side support for a slight rebound in the polyolefin market. Upstream supply is expected to remain at a high level, but there is significant inventory pressure. Downstream demand is in a seasonally improving phase, with overall downstream factory operating rates rising slightly, but the fundamental situation remains weak [3] Summary by Directory 1.

Report Summary 1. Report Industry Investment Rating - Unilateral: Neutral; Inter - period: None; Inter - variety: None [3] 2. Core Viewpoints - International oil prices rebounded, strengthening the cost support of oil - based production. Propane prices rose slightly, and the profit of PDH - made PP was near the break - even point. The number of PE shutdown and maintenance devices increased, slightly alleviating the supply pressure. However, the overall current operation was still at a relatively high level, with inventory accumulation in production enterprises and certain de - stocking pressure upstream. The PP operation rate was flat month - on - month, and the inventory in the upstream and mid - stream links decreased slightly. The new 900,000 - ton/year Phase II device of Daxie Petrochemical started trial operation, and it was expected to produce qualified products soon. The continuous release of new production capacity would bring greater supply pressure in the long - term. The recovery of downstream demand was slow. The agricultural film entered the seasonal demand conversion stage, with the overall order follow - up slow and the terminal operation recovering slightly [2] 3. Summary According to the Directory a.

Report Industry Investment Rating - Unilateral: Neutral. No strategy for inter - period trading [3] Core Viewpoints - Yulong Petrochemical's three - line maintenance and the upcoming maintenance season for upstream petrochemical plants have led to an increase in maintenance losses, easing market supply pressure and resulting in a slight reduction in production inventory. The anti - involution policy on the macro level has some positive impact, with an expected improvement in the medium - to - long - term supply side, but the short - term fundamentals of polyolefins have not significantly improved. The geopolitical situation in the Middle East is gradually easing, leading to lower international oil and propane prices. The production profit of PDH - made PP has turned from loss to profit, and the cost - side support has weakened. Downstream demand remains in the seasonal off - season, with the agricultural film industry's starting rate rising from the bottom, the plastic braiding industry's starting rate decreasing, and other downstream industries maintaining their starting rates, mainly for rigid - demand procurement [2] Summary by Directory 1.

Polyolefin Inventory - The text mentions that production inventory has a slight reduction, but no specific inventory data is provided [2]

Report Industry Investment Rating - Unilateral: Neutral; Inter - period: None [3] Core Viewpoints - The market trading of macro - positive factors has ended, and the atmosphere of waiting and seeing prevails. Downstream factories have low purchasing sentiment, and most end - users make purchases based on rigid demand. Upstream petrochemical plants will enter the maintenance season, and the maintenance loss is on the rise, alleviating the market supply pressure and leading to a slight reduction in production inventory. The geopolitical situation in the Middle East is gradually easing, international oil prices and propane prices are falling, the production profit of PDH - made PP has turned from loss to profit, and the cost - side support has weakened. The downstream demand remains in the seasonal off - season, with the bottom - up recovery of the agricultural film industry's start - up rate and the decline of the plastic weaving industry's start - up rate [2] Summary by Directory 1.

Polyolefin Inventory - Upstream petrochemical plants will enter the maintenance season, and production inventory has a slight reduction [2]

Report Industry Investment Rating - The report suggests a cautious and bearish stance on plastics for unilateral trading, with no specific strategy for inter - period trading [3] Core Viewpoints - It is the off - season for downstream demand, with limited boosting effects. The agricultural film industry has low operating rates, and other end - user industries are running weakly. Upstream inventory is being depleted, while inventory reduction in the mid - stream trading sector is slow. International oil and propane prices have dropped significantly, weakening the cost support for polyolefins. Some previously shut - down and overhauled plants have resumed operation, and new supply has slightly increased. However, petrochemical plants are about to enter the traditional overhaul season, and future intensive overhauls of existing plants will relieve some of the new supply pressure [1][2] Summary by Directory 1.

Polyolefin Inventory - Upstream inventory is being depleted, while inventory reduction in the mid - stream trading sector is slow. No specific inventory data is provided [2]

Report Industry Investment Rating No information provided Core View of the Report The supply of polyolefins is under pressure due to the expected restart of multiple previously shut - down plants and the ramp - up of new production capacities. The cost support for polyolefins has increased with the rising international crude oil prices. The propane price has been weakening, leading to a slight increase in the start - up rate of PDH - based PP production. It is the traditional off - season for polyolefin downstream demand, with the agricultural film start - up rate continuing to decline and other terminal start - up rates being weakly volatile. Terminal factories have low enthusiasm for raw material procurement, mainly making rigid - demand purchases. The inventories of upstream factories and traders are being slowly depleted. The strategy for plastics is to be cautiously bearish on the single - side, and there is no strategy for the inter - period [1][3][4] Summary According to Relevant Catalogs 1. Polyolefin Basis Structure The L main contract closed at 7106 yuan/ton (+28), the PP main contract closed at 6941 yuan/ton (+9), the LL spot price in North China was 7140 yuan/ton (+50), the LL spot price in East China was 7120 yuan/ton (+20), the PP spot price in East China was 7080 yuan/ton (+10), the LL basis in North China was 34 yuan/ton (+22), the LL basis in East China was 14 yuan/ton (-8), and the PP basis in East China was 139 yuan/ton (+1) [2] 2.

Report Investment Rating - No investment rating provided in the report Core Viewpoints - The terminal downstream demand for polyolefins has entered the traditional off - season, with limited market demand, general restocking enthusiasm, mainly rigid - demand procurement, and a cold market trading atmosphere. The supply side continues to increase, and the supply - demand contradiction has not been significantly improved. Currently, the number of PE inventory maintenance devices has increased, alleviating the PE supply side. The previously shut - down PP devices have gradually restarted, and the upstream production inventory of polyolefins has been depleted. It is expected that the future supply will increase. The downstream demand is in the off - season, the agricultural film operating rate is at a low level, the packaging film operating rate fluctuates slightly, and the operating rates of industries such as plastic weaving and BOPP have increased slightly [2] - For the trading strategy, it is recommended to be cautiously bearish on plastics for single - side trading, and there is no strategy for inter - period trading [3] Summary by Directory 1.
