1. Report Industry Investment Rating There is no information provided regarding the report industry investment rating in the given content. 2. Core Views Industrial Silicon - In the second half of the year, the industrial silicon industry is in a cycle of accelerating the exit of backward production capacity and will enter the de - stocking process. The supply pressure will be continuously released with the implementation of production plans in Southwest China during the wet season. The downstream demand is expected to strengthen, but if the integration of the photovoltaic industry makes substantial progress, it may suppress the demand for industrial silicon in the future. Overall, the price of industrial silicon will show a wide - range oscillation trend [4]. Polysilicon - In the second half of the year, the polysilicon market is at a stage where the fundamental logic and the "anti - involution" logic alternate. From the fundamental perspective, the expected reduction in electricity prices and the expansion of profits may prompt enterprises to increase production capacity, while the demand increment in the second half of the year is limited, and the inventory pressure is high. From the "anti - involution" logic, effective integration agreements or coordinated production - reduction measures may improve the industry situation and drive up prices [11]. 3.

Report Industry Investment Rating - Not provided in the content Core Viewpoints of the Report - The industrial silicon market continues to face issues of oversupply and insufficient effective demand in the long - term. The short - term price increase is mainly driven by the "anti - involution" and supply - side reform 2.0 expectations, which have led to a surge in market sentiment. However, there are signs that the short - term exuberant sentiment may fade, and attention should be paid to the risk of a significant price drop when the sentiment wanes. It is also recommended that relevant enterprises seize hedging opportunities while controlling margin (cash flow) safety [16]. Summary by Directory 1.

At the daily - line level, the short - term rebound trend continued, but the upward momentum became looser. Short - term attention should be paid to the price performance at the resistance level around 10,000 yuan/ton, and be wary of the risk of price decline [63].

Group 1: Report Industry Investment Rating - No relevant content Group 2: Core View of the Report - On July 24, polysilicon fluctuated higher, with the main contract 2509 closing at 53,765 yuan/ton, an intraday increase of 5.15%, and the position increasing by 6,923 lots to 173,000 lots. The price of N-type recycled polysilicon increased to 46,000 yuan/ton, and the price of the lowest deliverable silicon material also rose to 46,000 yuan/ton, with the spot discount widening to 7,740 yuan/ton. The main contract 2509 of industrial silicon closed at 9,690 yuan/ton, an intraday decrease of 0.21%, and the position increasing by 1,498 lots to 336,000 lots. The reference price of Baichuan's industrial silicon spot was 9,807 yuan/ton, remaining stable compared to the previous trading day. The price of the lowest deliverable 421 increased to 9,550 yuan/ton, and the spot discount narrowed to 45 yuan/ton. Affected by the news of coal mine inspections, industrial silicon also has a cost upward logic support. Currently, the country continues to send a strong signal against cut - throat competition. With multiple positive news in the crystalline silicon market, the bulls are quite confident. Supported by macro - policies, the market is more likely to rise than fall. Attention should be paid to the PS/SI price ratio and the potential upward trend before the implementation of policies. In addition, after the increase in polysilicon margin, it is more difficult to chase the rise, so it is necessary to control positions carefully and be vigilant against high - volatility risks [1] Group 3: Summary by Directory 1. Research View - Polysilicon prices rose on July 24, with the main contract showing an increase and the position rising. The prices of different types of polysilicon materials also increased, and the spot discount widened. Industrial silicon prices slightly declined, with the position increasing. The spot price remained stable, and the spot discount narrowed. Industrial silicon has cost - rising support, and the market is likely to rise under policy support, but there are risks in chasing the rise of polysilicon [1] 2.
