Market Dynamics - The market is unlikely to form a cohesive force like in 2021 due to the increasing number and speed of project launches [1] - The inherent value of altcoins is zero, but the "shell" has value [2] - The value of "shells" is decreasing [2] Trading Strategy - Projects listed on Binance spot exchanges are generally considered "garbage" because the primary goal is to sell off holdings [4] - Listing on spot exchanges leads to dispersed token ownership, making it difficult to accumulate tokens for price manipulation [4] - Before, main forces would consider going through cycles to collect chips and pull the market in a bull market, but now they just sell as much as they can [2][4] Cryptocurrency Landscape - In 2022, there were only 6-8 projects with market capitalization below 30 million, and most of them increased by at least 3 times [2] - After October 11th, the number of projects with market capitalization below 20 million was approximately 50-60 [3]

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].

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]. PTA - The short - term drive is limited, and it will mainly fluctuate at a low level. It is recommended to wait and see TA, pay attention to the support around 4500, and conduct rolling reverse spreads on TA1 - 5 [9]. Ethylene Glycol - It is expected to accumulate inventory in October, and the supply - demand structure is weak in the far - month. It is recommended to short EG01 on rallies, hold the seller of the out - of - the - money call option EG2601 - C - 4350, and conduct reverse spreads on EG1 - 5 [9]. Short Fibers - The absolute price is still under pressure in the short term, but it is relatively strong compared to raw materials due to low inventory. It is recommended to have the same strategy as PTA for the unilateral position, and widen the processing margin at a low level [9]. Bottle Chips - It is likely to enter the seasonal inventory accumulation channel. PR follows the cost end, and the processing margin improves in the short term. It is recommended to have the same strategy as PTA for the unilateral position, and the main contract processing margin is expected to fluctuate between 350 - 500 yuan/ton [9]. Pure Benzene - The overall supply and demand in October are expected to be loose, and the price drive is weak. BZ2603 follows the fluctuations of styrene and oil prices [10]. Styrene - The supply - demand is expected to be loose, and the price is still under pressure in the short term. EB11 should be treated as a short - selling opportunity on rebounds [10]. 3.
