Report Industry Investment Rating There is no information provided in the content about the report industry investment rating. Core Viewpoints The report analyzes the mid - term and short - term structures of various energy and chemical products, and provides corresponding trading strategies based on the fundamental and technical analysis of each product. The overall market shows a complex situation with different trends for different products, and many products are affected by factors such as supply - demand relationship, cost, and geopolitical events [1][2]. Summary by Product Crude Oil - Logic: OPEC+ starts the second - stage 165 barrels/day复产 plan. In October, it will increase production by 137,000 barrels/day. The market has a large surplus expectation after the first - stage复产, and the second - stage复产 will add to the pressure with the demand shifting from peak to off - peak season. Geopolitical events and sanctions expectations bring short - term support, but the fundamental trend is downward [2]. - Technical Analysis: Mid - term and short - term downward structures. The intraday trend is a bit subtle, testing the short - term pressure of 489 (11 contract). It is recommended to observe for one more day. The hourly - level short positions can be held cautiously [2]. Styrene (EB) - Logic: The weekly start - up rate has a slight increase, but there are unplanned maintenance. The downstream profit is poor, the start - up rates of ABS and EPS decline, and the port inventory continues to accumulate, which is a short - term pressure point. After the autumn maintenance peak, there will be new device put - into - production pressure in September - October, and the supply - demand situation is weak. There is also the risk of inventory over - filling [5]. - Technical Analysis: The hourly - level short - term downward structure is being tested. After a sharp fall, it is in a normal repair period. It has reached above the short - term pressure of 7040 (10 contract). The remaining short positions can be held cautiously, with the final stop - profit at 7180 [5]. Rubber - Logic: Seasonal factors are strong, but there is no weather speculation on the supply side. Only short - term typhoons and rainy seasons make raw material prices strong. The import volume in August increases both year - on - year and month - on - month, with a continuous increase expectation. The start - up rate of semi - steel tires decreases significantly, while that of all - steel tires remains high. The current fundamentals are neutral [7]. - Technical Analysis: Mid - term oscillation structure at the daily level, and the hourly - level upward structure is being tested. After an increase in positions and a fall below the support of 15880, the short - term upward trend is under threat. It is close to the lower limit of the August range. It is recommended to wait and see at the hourly level and look for short - selling opportunities on the 15 - minute chart after a rebound fails to break through the pressure of 16000 [7]. Synthetic Rubber (BR) - Logic: There is no major contradiction in the supply - demand of styrene - butadiene rubber. The start - up rate and output of some devices decrease due to maintenance, and the inventory of downstream semi - steel tires also drops. The main contradiction lies in the cost of butadiene. With the arrival of a large number of ships, the port inventory has increased significantly, ending the previous tight situation. In the medium term, the supply pressure of butadiene will gradually appear, and the upstream crude oil will also face surplus pressure [10]. - Technical Analysis: Mid - term oscillation/downward structure at the daily level, and short - term downward structure at the hourly level. Since August 22, the position has increased by 97%. After an increase in positions and a break - through today, it may end the oscillation and turn to a downward trend. The short - term pressure is at 11760. The 15 - minute short positions can be held at the hourly level, with the stop - profit at 11760 [13]. PX - Logic: The profit of PX is restored, and the start - up rate is increasing after the maintenance peak. The domestic PX load is 83%, and the Asian PX load is 75%. The demand - side device maintenance and复产 co - exist, but the overall start - up rate of PTA has declined, and the previous inventory reduction has slowed down. The short - term fundamentals have weakened, and more attention should be paid to the cost of crude oil [17]. - Technical Analysis: The hourly - level short - term downward structure is being tested. The intraday trend is oscillatory, and the small - cycle should pay attention to the pressure at 6770 on the 15 - minute chart. The remaining short positions can be held [17]. PTA - Logic: It lacks its own driving force, and attention should be paid to the cost collapse logic of crude oil [21]. - Technical Analysis: Hourly - level short - term downward structure. The intraday oscillation does not change the downward trend. The short - term pressure is at 4700. The short positions can be held, with the stop - profit at 4700 [21]. PP - Logic: The supply - side start - up rate increases, and new devices will be put into production. The demand enters the peak season, and the supply - demand pressure is not obvious. Attention should be paid to the cost collapse logic [22]. - Technical Analysis: Hourly - level short - term downward structure. The intraday trend is oscillatory. The short - term pressure at the hourly level is 7090, which is relatively far. Attention can be paid to the 6990 pressure on the 15 - minute short - cycle. If it breaks through, partial stop - profit can be made [22]. Methanol - Logic: The domestic and overseas start - up rates are high, and the arrival pressure in September is large. The port inventory continues to accumulate, reaching a record high in the past 5 years. The downstream demand is weak, and the short - term pressure is great [24]. - Technical Analysis: Mid - term downward/oscillation and short - term downward structures. After an increase in positions and a fall, the 15 - minute cycle turns down. Attention should be paid to whether the hourly - level downward slope returns. The short - term pressure is at 2435. The remaining short positions can be held cautiously, with the final stop - profit at 2435 [24]. PVC - Logic: After the previous maintenance, the start - up rate remains at a high level of 75%. The comprehensive profit of chlor - alkali is strong, so the supply is difficult to reduce. The inventory continues to accumulate to the highest level in the same period of history. Before the real estate bottoms out, the demand is difficult to improve, and the fundamentals are bearish [27]. - Technical Analysis: Mid - term upward structure at the daily level and short - term downward structure at the hourly level. The intraday oscillation does not change the downward trend. The short - term pressure is at 4930. The short positions can be held [27]. Ethylene Glycol (EG) - Logic: The port inventory is at a low level in recent years, so the fundamentals are relatively strong compared with other energy and chemical products. But with the increase in domestic start - up rate, it is expected to enter the inventory - accumulation cycle. The short - term situation is strong, but the medium - term expectation is bearish [30]. - Technical Analysis: Mid - term oscillation/downward and short - term downward structures. The intraday oscillation, but the closing price hits a new low, and the short - term decline may accelerate. The short - term pressure is at 4375. The short positions can be held, with the stop - loss at 4375 [30]. Plastic - Logic: The start - up rate of PE is stable, and the demand improvement in the peak season is slow. The fundamental driving force is general [32]. - Technical Analysis: Mid - term oscillation/downward and short - term downward structures. The intraday trend is oscillatory. The short - term pressure at the hourly level is 7365, which is relatively far. Attention can be paid to the 7290 pressure on the 15 - minute small - cycle. The 15 - minute short positions can be held, with the stop - loss at 7290 [32]. Soda Ash - Logic: After the end of the anti - involution hype, the glass - soda ash with the greatest supply - demand pressure starts the spot - futures regression logic before delivery. The anti - involution has no real impact on the supply. The over - capacity trend continues, and the output has further increased after the price increase. The real estate demand is difficult to bottom out, and the supply - strong and demand - weak situation remains unchanged. The large inventory and high - output pressure continue to suppress the price [33]. - Technical Analysis: Hourly - level downward structure. The intraday oscillation does not change the downward trend. The short - term pressure is at 1320. The short positions can be held [33]. Caustic Soda - Logic: Last week, the supply - side output and start - up rate decreased due to autumn maintenance and transportation restrictions during the military parade. After the parade on September 3, the supply - side speculation may end. The export demand is at a high level but the profit is declining, and the domestic non - aluminum demand is rising in the early peak season, while the alumina demand remains flat at a high level. The overall supply - demand is strong, but the supply pressure is greater. The inventory is at a record high in the past 5 years, and there is an over - supply situation after the start - up rate recovers [36]. - Technical Analysis: Hourly - level downward structure. The intraday oscillation does not change the downward trend. The short - term pressure is at 2625. The short positions can be held, with the stop - profit at 2625 [36].
