Report Industry Investment Ratings - Propylene, Polypropylene, Styrene, PVC, Methanol: ★☆☆ (One star, indicating a bullish/bearish bias with a driving force for price increase/decrease, but limited operability on the trading floor) [1] - PTA, Ethylene Glycol, Short Fiber, Bottle Chip, Urea, Caustic Soda, Glass: ☆☆☆ (White star, indicating a relatively balanced short - term bullish/bearish trend and poor operability on the trading floor, suggesting waiting and seeing) [1] - Pure Benzene: Not rated in the table, but with analysis in the report [3] - PX: ☆☆☆ [1] - Soda Ash: The symbol in the table is unclear [1] Core Viewpoints - The chemical market shows a mixed trend, with different products having different price trends and supply - demand situations. Some products are affected by factors such as inventory, cost, demand, and policies, and their short - term and medium - term trends vary [2][3][5] Summary by Related Catalogs Olefins - Polyolefins - Propylene futures rose, with controllable enterprise inventories and stable offers. Downstream follow - up was okay, and the trading range was stable [2] - Polyethylene futures rose, but the market was waiting for news, with cost support weakening and supply pressure. Sellers mostly offered small discounts [2] - Polypropylene futures rose. Although the supply pressure decreased due to more upstream maintenance, the demand improvement in the peak season was limited, and the high - level inventory was slowly digested. The supply - demand contradiction may increase, and the price may remain low for a long time [2] Pure Benzene - Styrene - Pure benzene futures prices rebounded above 5500 yuan/ton. The spot price in East China rebounded, and the low - level transactions in Shandong improved. The short - term price may rebound, but the high import volume in the medium term is the main pressure [3] - Styrene futures rose, but there were only expected device shutdowns. The inventory remained high, and the upward price momentum was limited [3] Polyester - PX and PTA rebounded with reduced positions. The short - term price may continue to rebound, mainly depending on oil prices. In the medium term, with the weakening demand and expected inventory accumulation, the strategy is mainly reverse arbitrage [5] - Ethylene glycol rebounded with increased positions. The short - term price has a rebound expectation, but there is still inventory accumulation pressure in the medium term, suggesting shorting at high prices [5] - Short fiber continued to be a bullish allocation. The new production capacity was limited, the inventory was decreasing, and the downstream备货 sentiment was improved [5] - Bottle chip demand weakened, with inventory accumulation and pressure on processing margins. The long - term pressure is over - capacity [5] Coal Chemical Industry - Methanol fluctuated at a low level. The short - term coastal market may fluctuate within a range, and the price may be bullish in the medium - to - long term as the import supply pressure is expected to decrease [6] - Urea futures prices rose slightly. The short - term market is expected to fluctuate strongly within a range, supported by the marginal improvement of supply - demand and coal prices [6] Chlor - Alkali - PVC showed a fluctuating trend. The supply may increase, and it may operate at the bottom range due to weak domestic demand and potential export policy pressure [7] - Caustic soda fluctuated narrowly. The supply fluctuated slightly, and it is recommended to be cautious when shorting due to non - aluminum downstream restocking and a high basis [7] Soda Ash - Glass - Soda ash fluctuated strongly. The supply was still high, and it is recommended to short at high prices after a rebound [8] - Glass fluctuated narrowly. The inventory continued to accumulate, and the downward range is expected to be limited. It is advisable to pay attention to selling out - of - the - money put options [8]

Report Industry Investment Ratings No relevant content provided. Core Views Polyolefins - The supply of PE is increasing steadily, with significant profit improvement, continuous increase in the operating rate, and limited planned maintenance. Overseas inventory clearance at the end of the year also brings impacts, highlighting long - term supply pressure. PP's valuation has been significantly repaired due to the sharp decline in propane and crude oil. Although there are more recent overhauls in PP, the new device commissioning pressure in October is large, and the demand side lacks bright performance. The supply - demand structure of polyolefins is loose, and the upside space of the 01 contract is limited. Overall, the macro - environment is pessimistic, and the prices of PP and PE face pressure [2]. Methanol - At the port, due to sanctions, some warehouses do not accept sanctioned vessels, increasing the willingness to hold spot goods. Coupled with supply - side disturbances, the port basis has strengthened significantly. Overseas production has declined, and some devices have stopped. In late October, attention should be paid to the expected supply reduction caused by overseas gas restrictions. Inland supply has a certain bottom - support for prices due to a relatively healthy inventory structure. The demand side is weak. Overall, the price may continue to fluctuate under the supply - demand game, and attention should be paid to the port de - stocking rhythm and the implementation effect of overseas gas - restriction expectations [4]. Benzene - Styrene - For pure benzene, although there are device overhauls, there are also new production capacity commissioning expectations, and the domestic supply is expected to remain at a relatively high level. The downstream demand support is limited, and the inventory in East China ports may continue to decline. The price drive is weak in October. For styrene, under the double pressure of inventory and industry profit, some devices are under overhaul, but new devices are about to be commissioned, and the overall supply will remain high. The demand side support is also limited, and the price drive is weak. In the short - term, the price is still under pressure [6]. Polyester Industry Chain - For PX, the supply has shrunk compared to expectations due to unexpected overhauls or load reductions of some devices, while the demand has increased. However, overall, the supply - demand is still weak, and the price is in a weak oscillation. For PTA, the spot basis continues to weaken, but the downward space is limited. The absolute price is also in a weak oscillation. For short - fiber, the price is supported in the short - term, but the cost - side support is weak. For bottle - chips, it is likely to enter a seasonal inventory accumulation period, and it follows the cost - side fluctuations. For ethylene glycol, the domestic supply is abundant, and it is expected to accumulate inventory in October, with the upper price limit under pressure [7]. PVC and Caustic Soda - For caustic soda, the demand support from the aluminum industry is weak in the short - term, but there may be long - term demand support. The supply is increasing in the short - term, and the price is weak. For PVC, the supply - demand pressure is large, the fundamental contradiction is difficult to resolve, and the price is weak. The cost - side provides bottom support, and short - term short positions can stop profit [8].

Core Views The report provides investment strategies and market analyses for various futures products. It takes into account factors such as macroeconomic data, industry events, supply - demand relationships, and international policies. For example, in the macro - financial sector, important meetings and potential Fed rate cuts support the stock market, while in the bond market, the outcome of Sino - US negotiations is crucial. In the black building materials sector, supply and demand factors affect the prices of coking coal, rebar, etc. Each sector's analysis is based on a combination of multiple factors to guide investment decisions [5][7][8]. Summaries by Categories Macrofinance - **Index Futures**: Last week, A - share broad - based indices all had negative weekly returns, with the ChiNext and STAR Market indices having the largest declines. This week, the release of macro - economic data and important events will affect the market. With the approaching of important meetings and the potential Fed rate cuts, the market is expected to be supported. It is recommended to buy on dips in the medium to long term [5]. - **Treasury Bonds**: Interest - rate bond yields declined across all tenors and varieties, and credit - bond yields also decreased. Overseas credit risks led to a decline in risk appetite, but the compound negative factors in the bond market have not been fundamentally resolved. It is advisable to take partial profits during risk - event shocks. The Sino - US negotiations at the end of the month will be the key to determining market risk appetite [5]. Black Building Materials - **Coking Coal and Coke**: During the National Day, supply was temporarily halted and is expected to gradually recover after the holiday. The supply recovery is relatively slow, and coking coal has long - position value. After the holiday, the first round of coke price increases started, supported by steel mills' demand [7][8]. - **Rebar**: Last Friday, rebar futures prices oscillated. The fundamental situation shows that the price is undervalued, and with the improvement of demand and the decline of production, the price is expected to oscillate at a low level. It is recommended to pay attention to the opportunity to go long around 3000 for the RB2601 contract [8]. - **Glass**: After the National Day, environmental protection and macro - policy expectations cooled down, and the market returned to the fundamental logic. Supply is increasing, demand is weak, and the inventory is rising. It is recommended to observe and wait for a reversal to consider going long [9][10].

The domestic supply has recovered, and overseas Iranian devices have resumed production, but future production increases are limited due to winter gas restrictions. It is recommended to pay attention to the strategy of going long on methanol and short on polyolefins and the positive spread strategy between months [6]. - **Polyolefins**: On Thursday, polyolefin prices showed different trends. The short - term supply will remain high, and the marginal increase in demand in October will gradually decline. With the weakening of crude oil prices, polyolefin prices will be weak [6]. - **Polyvinyl Chloride (PVC)**: On Thursday, PVC prices in different regions showed oscillating trends. The supply remains high, domestic demand has slowed down, and exports are expected to be weak. The total inventory pressure is large, and PVC prices are expected to oscillate weakly [8]. 3.2 Daily Data Monitoring - The report provides the basis data of various energy and chemical products on October 16 and 15, including spot prices, futures prices, basis, basis rates, and their changes, as well as the quantile of the latest basis rate in historical data [9]. 3.3 Market News - U.S. President Trump said that Indian Prime Minister Modi promised to stop purchasing Russian crude oil, but India did not comment.

1. Investment Ratings No investment ratings for the industries are provided in the reports. 2. Core Views Methanol - The price may continue to fluctuate under the game of supply and demand. Focus on the stability of overseas device operation, the customs - clearance efficiency of sanctioned vessels, and actual arrival performance. Pay attention to the port destocking rhythm and the implementation effect of overseas gas - limiting expectations [1]. Polyolefins (LLDPE & PP) - The inventory pressure after the holiday is still significant. The supply pressure is prominent in the medium - and long - term, and the demand lacks highlights. The upside space of the 01 contract is limited [5]. Caustic Soda - There is demand support in the medium - and long - term, but it is weak in the short term. It was previously recommended to be bearish, and now the short positions can be temporarily closed as the market stabilizes [8]. PVC - The short - term disk may continue to be under pressure. Although the supply pressure has slightly eased and exports have recovered, the demand in the peak season is weak. Pay attention to cost support and downstream demand performance [8]. PX - The supply and demand are expected to be weak in the fourth quarter. It will mainly fluctuate at a low level in the short term. It is recommended to wait and see and look for short - selling opportunities on rebounds, and mainly conduct reverse spreads on the monthly spread [9].
