Report Summary Industry Investment Ratings No industry investment ratings are provided in the reports. Core Views - **Oils and Fats**: Overall, a phase of bearish sentiment is maintained. Palm oil may test the support around 9000 yuan, and the market is expected to gradually stabilize if it can find support at this level. Soybean oil has a mix of bullish and bearish factors, and the domestic futures market may maintain a narrow - range shock adjustment. The spot basis quotation may have limited fluctuation space [1]. - **Sugar**: The raw sugar price has limited rebound momentum due to supply expectations. It is expected to fluctuate between 15 - 16 cents per pound. The 9 - month production and sales data is moderately bearish, and the market is expected to maintain a shock - weak pattern [3][4]. - **Meal Products**: The spot price of domestic soybean meal is expected to have limited upward movement this year, but the downward space is also limited. If the market does not purchase US soybeans, the M2601 contract has support around 2900, and attention should be paid to the uncertainty of arrivals [6]. - **Pigs**: In the long - term, the supply pressure of pigs in the fourth quarter will continue to be released, and the pig price is not optimistic. The policy - driven industry capacity reduction effect needs time to materialize, and the spot price is expected to face pressure until the first half of next year. The short - term disk operation may be strong, but the upward space is limited [9]. - **Corn**: In the short - term, the slow increase in corn supply supports the price, but it is under pressure from the supply side. The disk is expected to maintain a low - level shock [12][14]. - **Cotton**: In the short - term, cotton prices will fluctuate within a range. The Zhengzhou cotton main contract has cost support at low levels, but there is also increasing hedging pressure above 13500 - 13600. The downstream terminal demand is weak, but textile enterprises have demand for cotton raw materials at current prices [15]. - **Eggs**: The egg price is expected to rise slightly this week and then stabilize for observation, but there is still overall pressure due to sufficient supply and improving demand [19]. Summary by Related Catalogs Oils and Fats - **Price Changes**: On October 22, compared with October 21, the prices of soybean oil, palm oil, and rapeseed oil all decreased to varying degrees.

Meal Products - **Price and Inventory**: The prices of domestic soybean meal, rapeseed meal, and soybeans showed minor changes. The inventory of domestic soybeans and soybean meal is still at a high level, and the recent purchase has slowed down due to poor crushing margins [6]. - **Market Influencing Factors**: The improvement of the US soybean export expectation, the smooth sowing of Brazilian new - crop soybeans, and the high domestic soybean import volume all affect the market. The uncertainty of soybean arrivals also needs attention [6]. Pigs - **Market Conditions**: On October 22, the futures price of pigs decreased slightly, while the spot price increased. The slaughter volume increased slightly, and the prices of piglets, sows, and other indicators also changed. The breeding profit decreased significantly [9]. - **Influencing Factors**: The short - term rebound of pig prices is mainly due to secondary fattening, but the long - term supply pressure is still large, and the policy - driven capacity reduction effect needs time to be reflected [9]. Corn - **Price and Inventory**: On October 22, the price of corn futures decreased, and the basis increased. The inventory of corn and corn starch changed, with the corn warehouse receipt increasing significantly [12]. - **Market Influencing Factors**: The weather in different regions affects the corn harvest and price.

Cotton - **Market Conditions**: On October 22, the price of cotton futures decreased slightly, and the spot price increased slightly. The commercial inventory increased significantly, while the industrial inventory decreased slightly. The import volume increased [15]. - **Influencing Factors**: The firm purchase price of Xinjiang machine - picked seed cotton provides cost support, but the weak downstream terminal demand and increasing hedging pressure limit the upward space of cotton prices [15]. Eggs - **Market Conditions**: On October 22, the price of egg futures decreased, and the spot price remained unchanged. The price of egg - laying chicken seedlings remained unchanged, and the price of culled chickens decreased. The egg - to - feed ratio and breeding profit decreased [18][19]. - **Influencing Factors**: The high inventory of laying hens, the improvement of egg - laying rate and egg weight, and the increasing demand from downstream trade - ups all affect the egg price [19].

Report Industry Investment Ratings - No industry investment ratings are provided in the reports. Core Views Industrial Silicon - Industrial silicon spot prices are stable, while futures prices fluctuate and closed down 60 yuan/ton to 8,505 yuan/ton. September's export volume decreased by 8% month-on-month to 70,200 tons but remained year-on-year growth. In October, the supply of industrial silicon increased significantly, with a risk of inventory accumulation and price pressure. Although some enterprises in the southwest region reduced production, the impact on output was small, and the supply side still increased due to the increase in Xinjiang's output. Considering the potential increase in raw material costs such as coal prices and the rise in electricity prices in November, the future price center is expected to move up. Currently, the price is expected to fluctuate at a low level, mainly in the range of 8,000 - 9,000 yuan/ton. If the price of the 11 - contract falls to the low level of 8,000 - 8,300 yuan/ton, one can consider buying on dips [1]. Polysilicon - The spot price of polysilicon rose by 0.2 yuan/kg to 53 yuan/kg, and the futures price fluctuated and slightly rebounded by 375 yuan/ton to 50,715 yuan/ton, with futures at a discount. On the demand side, the output of silicon wafers increased significantly, and the demand for battery wafers was supported by overseas purchases driven by India's ALMM policy and the demand for high - efficiency wafers in domestic centralized projects. It is highly likely that the output will increase in October. Whether the demand can absorb the increased output during the fourth - quarter rush installation and the increase in export orders will have a significant impact on prices. Currently, the polysilicon market is relatively stable. One should pay attention to policy implementation, production control, and whether there is an increase in demand orders. In the future, the supply in the southwest region will decrease during the dry season, which will support prices, but one should guard against the risk of inventory accumulation due to lower - than - expected demand [2]. Glass and Soda Ash - Soda ash continues to weaken, with manufacturers' inventories and mid - stream delivery inventories increasing, highlighting the surplus. The weekly output is at a high level, and the surplus is obvious compared with the current rigid demand. Most of the inventory has been transferred to the mid - and downstream, and the trade inventory continues to rise. In the medium term, there is no expectation of a significant increase in downstream production capacity, so the overall demand for soda ash will continue the previous rigid - demand pattern. If there is no actual production capacity exit or load reduction, the supply - demand situation will be further pressured. One can track macro fluctuations and the load - control situation of soda ash plants. The overall supply - demand pattern is bearish, and the operation idea is to short on rebounds [4]. - Glass manufacturers' sales are average, and they continue to cut prices. Hubei's price is basically at par with the futures market. In recent days, the futures market has continued to weaken, trading on the logic of a non - prosperous peak season and fundamental surplus. In addition, the mid - stream inventory in some regions remains high without obvious destocking. In terms of industry supply - demand, although the deep - processing orders have improved seasonally, they are still weak, and the LOW - E开工率 remains low without obvious peak - season characteristics. In the long - term, the real - estate cycle is at the bottom, and the industry needs to clear production capacity to solve the surplus problem. Currently, the futures market has been trading on the non - prosperous peak - season logic. In the medium term, one should pay attention to the spot trading rhythm, high - frequency data changes, and macro - level drivers [4]. Natural Rubber - On the supply side, the prices of overseas raw materials have been firm recently, and the significant destocking of dark - colored rubber still provides cost support for rubber prices. However, there is a strong expectation that the weather in northeastern Thailand will improve, and the raw material prices are expected to weaken. One should pay attention to future weather conditions. On the demand side, after the "Double Festival" holiday, most of the enterprises that had maintenance have resumed normal production, but the overall market has not shown obvious improvement. To control inventory growth, some enterprises are still in a state of flexible production control. It is expected that the enterprise equipment will operate stably in the short term, adjusting production according to their own orders. In summary, the short - term macro - environment has improved, and the rubber price has rebounded due to the improvement in fundamentals. One should pay attention to the raw material output in the peak - production season of the main producing areas and macro - level changes. If the raw material supply is smooth, the rubber price may decline further; if not, the rubber price is expected to operate around 15,000 - 15,500 [5]. Logs - The log futures fluctuated yesterday, with the 2601 contract closing at 838 yuan/cubic meter, up 3.5 yuan from the previous day. The spot prices of the main benchmark delivery products remained unchanged, with the price of 3.9 - meter medium - A radiata pine in Shandong being 760 yuan/cubic meter and that in Jiangsu being 780 yuan/cubic meter. Last week, the inventory decreased. As of October 17, the total inventory of coniferous logs in the country was 2.92 million cubic meters, a decrease of 70,000 cubic meters from the previous week. On the demand side, the outbound volume increased. As of October 17, the daily average outbound volume of logs was 63,200 cubic meters, an increase of 5,900 cubic meters from the previous week. On the supply side, this week, 12 New Zealand log ships are expected to arrive at 13 Chinese ports, an increase of 0 from the previous week; the total arrival volume is about 438,000 cubic meters, an increase of 20,000 cubic meters from the previous week, a week - on - week increase of 5%. Currently, there is no obvious driving force in the supply - demand of logs. The 01 contract is relatively strong. The new round of overseas quotes has increased, and the subsequent port fees are expected to rise, providing strong cost support. During the seasonal peak season, there is some support below the futures price, and the 01 contract may be strong [6].
