周度报告—工业硅/多晶硅 smingfTable_Title] 工业硅现实与预期存分歧，多晶硅新增交割 品牌 | | | 有 色 金 属 8 月第一周现货成交清淡，成交价格变化不大，致密料主流价 格 42-47 元/kg，致密复投 45-50 元/kg，颗粒硅 43-46 元/kg。截 至 8 月 7 日，中国多晶硅工厂库存 23.3 万吨，周环比+0.4 万 吨。虽然多晶硅限价已经落实，但是减产仍未启动，预计 8 月 多晶硅产量提升至 12.5-13 万吨，导致单月过剩 1.5-2 万吨。本 轮多晶硅"反内卷"一阶段价格调控于协会公布指导价格后基 本确定；二阶段多晶硅价格继续上冲的力量或来自于纾困基金 和产能重组计划，后续产能退出与减产动作或将逐步落实，使 得基本面向政策目标靠拢，关注后续进展。 ★投资建议 工业硅：基于新疆大厂复产不及预期和多晶硅大量增产的现 实，工业硅基本面边际好转进入去库状态。但若基于新疆大厂 终将复产、多晶硅反内卷之下终将减产的预期，则工业硅基本 面又难言乐观。考虑到遏制通缩仍将是下半年政策主旋律，不 排除后续有二次交易"反内卷"的可能，短期之内我们仍推荐 逢低做多策略，风险在于大厂 ...

Report Industry Investment Rating - Industrial silicon: Volatility [6] - Polysilicon: Volatility [6] Core Viewpoints of the Report - The "anti-involution" sentiment has declined, but polysilicon still has policy support. The industrial silicon market may see marginal improvement, and it's difficult to reach previous low prices. The polysilicon spot price increase provides a lower limit for the futures market, and the price is expected to fluctuate between 45,000 - 57,000 yuan/ton in the short term [1][4] Summary by Relevant Catalogs 1. Industrial Silicon/Polysilicon Industry Chain Prices - The Si2509 contract of industrial silicon decreased by 1,225 yuan/ton to 8,500 yuan/ton week-on-week. The spot price of SMM's East China oxygenated 553 decreased by 400 yuan/ton to 9,700 yuan/ton, and the price of Xinjiang 99 decreased by 450 yuan/ton to 9,000 yuan/ton. The PS2509 contract of polysilicon decreased by 1,825 yuan/ton to 49,200 yuan/ton. The transaction price of N-type reclaimed feedstock increased by 300 yuan/ton to 47,100 yuan/ton [10] 2. "Anti-involution" Sentiment Declines, Polysilicon Still Has Policy Support - **Industrial Silicon**: The price of the main industrial silicon futures contract dropped significantly this week. The weekly output was 78,600 tons, a week-on-week increase of 4.59%. The social inventory increased by 5,000 tons, and the sample factory inventory decreased by 6,000 tons. Xinjiang's large factories have unstable operations, and production is expected to increase slightly. Sichuan and Yunnan's silicon factories are also expected to have a small increase. The 7 - month industrial silicon balance sheet is estimated to have a de - stocking of about 30,000 tons, and it may still de - stock in August [12] - **Organosilicon**: The price of organosilicon fluctuated this week. The overall enterprise operating rate was 72.26%, the weekly output was 47,800 tons, a week - on - week increase of 4.82%, and the inventory was 46,800 tons, a week - on - week increase of 2.41%. The price is expected to fluctuate [12][13] - **Polysilicon**: The main polysilicon futures contract first rose and then fell this week. The average spot transaction price increased. The main prices of silicon materials this week were 42 - 47 yuan/kg for dense materials, 45 - 50 yuan/kg for dense reclaimed materials, and 43 - 46 yuan/kg for granular silicon. As of July 31, the inventory of Chinese polysilicon factories was 229,000 tons, a decrease of 14,000 tons month - on - month. The production in August is expected to reach 125,000 - 130,000 tons, resulting in a monthly surplus of 20,000 - 30,000 tons [14] - **Silicon Wafers**: The price of silicon wafers increased as expected this week. The mainstream transaction prices of M10/G12R/G12 silicon wafers were 1.20/1.35/1.55 yuan/piece, with an average increase of 0.1 yuan/piece. The price is expected to increase slightly [15] - **Battery Cells**: The price of battery cells increased as expected this week. The mainstream transaction prices of M10/G12R/G12 battery cells were 0.29/0.285/0.285 yuan/watt, with increases of 0.02/0.015/0.015 yuan/watt respectively. The price should continue to rise, but the acceptance of the component end needs to be considered [16] - **Components**: The price of components fluctuated this week. The price of centralized components was stable, and the price of distributed components increased but with low trading volume. The component production in August is not expected to decrease significantly. The short - term component price is expected to fluctuate [17] 3. Investment Advice - **Industrial Silicon**: The "anti - involution" trading declined rapidly, and the industrial silicon futures price fell. In the short term, the decline sentiment has not been fully released, but the fundamentals have improved marginally. There may be a second "anti - involution" trading. Short positions can consider gradually taking profits, and then consider long positions after the macro - sentiment stabilizes. The risk lies in the resumption of production of large factories [19] - **Polysilicon**: The increase in the average spot transaction price provides a lower limit for the futures price. The price is expected to fluctuate between 45,000 - 57,000 yuan/ton in the short term. The overall strategy is to be bullish on dips, and one can consider selling out - of - the - money put options [20] 4. Hot News Sorting - The Guangzhou Futures Exchange added three polysilicon futures designated quality - inspection institutions on August 1. - The Guangzhou Futures Exchange adjusted the trading limits of some contracts of industrial silicon, polysilicon, and lithium carbonate futures on August 1 [21] 5.
