Report Industry Investment Rating - No relevant content provided Core Viewpoints - From September 5th to 11th, China's PE production decreased by 3.12% week-on-week to 612,800 tons, and the capacity utilization rate decreased by 2.51 percentage points to 78.04%.

Steel and iron ore are expected to be volatile, with the impact of production restrictions on steel weakening and iron ore showing an unexpected decline in molten iron production and a slight increase in port inventories [7]. - **Black Building Materials**: Despite the "anti - involution" impact, the prices of varieties in this sector are still supported during the peak season. However, most varieties are expected to be in a volatile state, such as coke starting the first - round price cut after the end of military parade - related production restrictions, and the supply of coking coal significantly decreasing [7]. - **Non - ferrous Metals and New Materials**: Affected by the better - than - expected July China's import and export data, non - ferrous metals were initially boosted. However, most varieties are expected to be volatile, with some facing downward pressure, such as copper due to the rising risk of overseas recession [7]. - **Energy and Chemicals**: The supply - demand situation of crude oil has weakened significantly, and coking coal's decline has dragged down the chemical industry. Most varieties in this sector are expected to be volatile, with some facing downward pressure, such as PP due to the increasing pressure of new production capacity [9]. - **Agricultural Sector**: The agricultural market is in a narrow - range volatile state, waiting for the results of field inspections. Most agricultural products are expected to be volatile, such as livestock products facing a supply - demand imbalance and rubber facing pressure from previous highs [9].

The downstream production rate has also increased slightly. The enterprise comprehensive profit is at a high level this year, the valuation pressure is large, the maintenance volume is small, and the production is at a historical high. The domestic downstream production is at a five - year low, and the export expectation has weakened after the Indian anti - dumping tax rate is determined [14]. - **Strategy**: Given the situation of strong supply, weak demand, and high valuation in the domestic market, it is recommended to consider short - position opportunities on rallies, but also beware of short - covering rallies [14]. 3.6 Benzene Ethylene - **Market Quotes**: The spot price remained unchanged, the futures price rose, and the basis weakened. The BZN spread is at a low level in the same period, with a large upward repair space [16][17]. - **Fundamentals**: The cost of pure benzene production is stable, and the supply is still abundant. The production rate of benzene ethylene has been increasing, and the port inventory has been decreasing significantly. The demand of the three S industries has declined. In the long term, the BZN spread may recover, and the price may rebound when the inventory reaches the inflection point of destocking [17]. - **Strategy**: It is recommended to go long on the pure benzene US - South Korea spread at low prices [17]. 3.7 Polyethylene - **Market Quotes**: The futures price fell [19]. - **Fundamentals**: The market expects favorable policies from the Chinese Ministry of Finance in the third quarter, and the cost has some support.

However, due to the commissioning of new PTA plants, the inventory accumulation of PX is not significant, and the terminal and polyester data are gradually improving. The valuation has limited downward space, but there is no strong upward driving force for PXN currently [22]. - **Strategy**: With the terminal and polyester data gradually improving, it is recommended to follow the crude oil and go long at low prices when the peak season arrives [22][23]. 3.10 PTA - **Market Quotes**: The PTA01 contract fell 10 yuan to 4688 yuan, the East China spot price fell 5 yuan to 4620 yuan, the basis was - 70 (- 7) yuan, and the 1 - 5 spread was - 32 (- 4) yuan [24]. - **Fundamentals**: The PTA production rate has increased, and the downstream production rate has also increased slightly.

The unexpected maintenance volume on the supply side has increased, and the inventory accumulation pattern has changed to destocking, but the processing fee is under pressure. The polyester fiber inventory pressure on the demand side is low, and the downstream and terminal production has improved, but the terminal recovery speed is slow [24]. - **Strategy**: It is recommended to follow PX and go long at low prices after the terminal performance improves in the peak season [24]. 3.11 Ethylene Glycol - **Market Quotes**: The EG01 contract fell 17 yuan to 4302 yuan, the East China spot price fell 25 yuan to 4414 yuan, the basis was 106 (- 11) yuan, and the 1 - 5 spread was - 48 (- 11) yuan [25]. - **Fundamentals**: The production rate of ethylene glycol has increased, and the downstream production rate has also increased slightly. The terminal production rate is flat. The import arrival forecast is 930,000 tons, and the port inventory has increased. The cost of ethylene is stable, and the coal price has increased. The domestic supply is high, and the port inventory is expected to be low in the short term due to low arrivals, but it will turn to inventory accumulation in the fourth quarter as imports arrive in a concentrated manner and the domestic production rate is expected to remain high [25]. - **Valuation Outlook**: The short - term valuation is supported by low arrivals, but there is downward pressure on the valuation in the medium term [25].
