1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - Yesterday, the overall atmosphere in the commodity market was strong, with the prices of finished steel products fluctuating upwards. In the medium - to - long - term, the steel price trend remains unchanged under the loosening macro - environment, but in the short - term, the weak real demand for steel is difficult to improve significantly. Attention should be paid to the policy strength and direction around the Fourth Plenary Session [2]. - The price of iron ore is expected to fluctuate weakly, and attention should be paid to the support level of 760 - 765 yuan/ton [5]. - For the black sector, it is more cost - effective to look for callback positions to do long rather than short. The market may first decline and then rise with the "Fourth Plenary Session" expectation [11]. - Manganese silicon and ferrosilicon are likely to follow the black sector's market, with low operation cost - effectiveness [12]. - The price of industrial silicon may rise in the long - term, and it may rise again if there are supply - side disturbances or policy drivers after the macro - risk is digested [15]. - The price of polysilicon rebounds under policy expectations, but the high price's sustainability depends on whether the policy can be implemented, and attention should be paid to risk control [17]. - The glass market lacks positive support and the sentiment is cautiously bearish [20]. - The soda ash market is expected to remain weakly operating in the short - term [22]. 3. Summary by Related Catalogs Steel Market Information - The closing price of the rebar main contract was 3049 yuan/ton, up 15 yuan/ton (0.494%) from the previous trading day. The spot prices in Tianjin and Shanghai were 3120 yuan/ton (down 10 yuan/ton) and 3190 yuan/ton (unchanged) respectively [1]. - The closing price of the hot - rolled coil main contract was 3219 yuan/ton, up 7 yuan/ton (0.217%) from the previous trading day. The spot prices in Lecong and Shanghai were 3230 yuan/ton and 3280 yuan/ton (both unchanged) respectively [1]. Strategy Viewpoints - Rebar production decreased slightly, and post - holiday demand led to a small inventory reduction, but overall demand recovery was insufficient. Hot - rolled coil production continued to decline, post - holiday demand increased, but inventory was still high, and the spread between hot - rolled coils and rebar continued to narrow [2]. - Trump's new tariff remarks affected market sentiment, but the medium - to - long - term steel price trend remained unchanged. In the short - term, the weak demand pattern was difficult to improve, and attention should be paid to policies around the Fourth Plenary Session [2]. Iron Ore Market Information - The main contract (I2601) of iron ore closed at 773.50 yuan/ton, with a change of - 0.39% (- 3.00). The position increased by 27213 hands to 53.56 million hands. The weighted position was 88.95 million hands. The spot price of PB powder at Qingdao Port was 777 yuan/wet ton, with a basis of 52.23 yuan/ton and a basis rate of 6.32% [4]. Strategy Viewpoints - In terms of supply, overseas iron ore shipments decreased seasonally. In terms of demand, the daily average pig iron output decreased, some blast furnaces were shut down for maintenance, and the steel mill profitability rate continued to decline. The terminal inventory pressure was high, and the iron ore price was under pressure. The price is expected to fluctuate weakly, and attention should be paid to the support level of 760 - 765 yuan/ton [5]. Manganese Silicon and Ferrosilicon Market Information - On October 16, the main contract of manganese silicon (SM601) closed at 5754 yuan/ton, up 0.14%. The spot price in Tianjin was 5680 yuan/ton, with a basis of 116 yuan/ton. The main contract of ferrosilicon (SF601) closed at 5456 yuan/ton, up 1.94%. The spot price in Tianjin was 5650 yuan/ton, with a basis of 194 yuan/ton [7][10]. Strategy Viewpoints - Manganese silicon's fundamentals are not ideal, and it may follow the black sector's market. If the black sector strengthens, attention should be paid to manganese ore disturbances. Ferrosilicon's supply - demand fundamentals have no obvious contradictions, and it is also likely to follow the market, with low operation cost - effectiveness [12]. Industrial Silicon and Polysilicon Market Information - The main contract of industrial silicon (SI2511) closed at 8605 yuan/ton, up 0.41%. The weighted position decreased by 463 hands to 429946 hands. The spot prices of 553 and 421 in East China were 9300 yuan/ton and 9700 yuan/ton (both unchanged) respectively, with bases of 695 yuan/ton and 295 yuan/ton [14]. - The main contract of polysilicon (PS2511) closed at 52575 yuan/ton, up 3.36%. The weighted position increased by 13651 hands to 278578 hands. The spot prices of N - type granular silicon, N - type dense material, and N - type re - feeding material were 50.5 yuan/kg, 51.25 yuan/kg, and 52.75 yuan/kg (all unchanged) respectively, with a basis of 175 yuan/ton [16]. Strategy Viewpoints - The price of industrial silicon may rise in the long - term due to factors such as reduced supply in the dry season in the southwest, cost support, and relative undervaluation. It may rise again if there are supply - side disturbances or policy drivers [15]. - The polysilicon price rebounds under policy expectations, but the high price's sustainability depends on policy implementation. Attention should be paid to risk control [17]. Glass and Soda Ash Market Information - The glass main contract closed at 1147 yuan/ton, up 1.59%. The spot prices in North China and Central China were 1210 yuan (down 10 yuan) and 1200 yuan (unchanged) respectively.

The top 20 long - position holders increased 14282 hands, and the top 20 short - position holders increased 7241 hands [21]. Strategy Viewpoints - The glass market has an expected increase in supply and a decrease in production cost, but the terminal demand is less than expected, and the market sentiment is cautiously bearish [20]. - The soda ash market has stable supply, weak demand, and light trading, and is expected to remain weakly operating in the short - term [22].
