1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The global macro situation this week focuses on changes in US dollar liquidity. Although there is short - term tightness, it won't have a significant impact on major asset prices. There are two factors for improvement: marginal easing of monetary policy and normal release of funds in the TGA account when the US government resumes work [7]. - In October, China's export growth was weaker than expected, but there were more positive signs in inflation data, and consumer data may slightly exceed expectations [7]. - In November, the macro environment enters a vacuum period, and major assets may enter a short - term shock period. However, the overall allocation idea in the fourth quarter remains unchanged, and the macro environment is still favorable for risk assets. It is recommended to allocate major assets evenly in the fourth quarter, hold long positions in stock indices, non - ferrous metals (copper, lithium carbonate, aluminum, tin), and precious metals, and increase positions appropriately if there is a correction [7]. 3.

Report Industry Investment Rating - Not provided in the given content Core Viewpoints - For LPG, demand improvement is limited and the futures valuation is high. The supply of domestic civil LPG is at a low level while the supply of etherified C4 remains high. The international propane price is strong. In the short term, there is a drive for the valuation to decline due to factors such as compressed PDH device profits [3][4]. - For propylene, the supply - demand pattern is expected to improve slightly. The current supply - demand is relatively loose, leading to a weak downward trend in prices. Next week, the supply is expected to contract and demand is expected to be stable, so there is an expectation of a stop - fall and rebound [7]. Summary by Directory LPG Part Price & Spread - Domestic spot prices of civil LPG fluctuate narrowly, and import costs increase significantly. For example, the price of Shandong civil LPG decreased by 60 yuan/ton week - on - week. FEI and CP are strong, and the import cost is supported. The FEI discount converges, the US - Far East arbitrage space expands, and the freight rate center moves up [9][22]. Supply - US propane shipments increase, with the increment mainly going to Asia. Middle East LPG shipments show different trends, and the total LPG commodity volume in China is 53.1 tons, a 1.2% week - on - week decrease. The propane supply in China is 71.21 tons, a 89.34% week - on - week increase, mainly due to an increase in international ship arrivals [36][66][78]. Demand & Inventory - The PDH operating rate increases and the MTBE operating rate remains stable. The inventory of LPG refineries is at a neutral level year - on - year with limited changes this week. The inventory of LPG terminals is at a relatively high level year - on - year, and the inventory in East China accumulates significantly [81][90][97]. Propylene Part Price & Spread - The international/US - dollar price of propylene further corrects, and the domestic price declines weakly and hits a new low. The profit of some upstream and downstream industries shows different trends, such as the significant contraction of PDH profit [106][111][119]. Balance Sheet - The operating rates of some units in the propylene industry chain change. The national supply and demand of propylene are expected to change slightly in the future. For example, the supply in November 2025 is expected to decrease slightly, and the demand is also expected to decrease slightly [127][132][136].

Report Industry Investment Rating - Not provided in the content Core Viewpoints - **LPG**: Short - term weak operation. Although PDH profit has improved significantly due to the weakening of propane, the current tense Sino - US trade relationship and strong market wait - and - see sentiment make it difficult to fully realize demand support.
