1. Report Industry Investment Rating - No information provided in the document. 2. Core Viewpoints - The "anti-involution" sentiment drives the price of silicon-based products to remain firm. The industrial silicon and polysilicon futures prices show an upward trend, and the short - term prices may continue to be strong, but there are still pressures in the medium - to - long - term [1]. - For industrial silicon, the supply may be less than expected, and the demand from polysilicon may increase due to potential restarts. The price rebounds from a low level, and short - term operations are recommended. In the long - term, the selling pressure on the upper side of the market may stimulate the resumption of production in the southwest region [1]. - For polysilicon, under the influence of supply - side reform expectations and market sentiment, the price may continue to be strong in the short - term. However, considering the limited improvement in fundamentals, price fluctuations may intensify, and short - term operations are also recommended [1]. 3.

It is recommended to focus on short - term operations. In the medium - to - long - term, the selling pressure on the upper side of the market may stimulate the resumption of production in the southwest region, and continuous attention should be paid to the actual production dynamics of silicon enterprises [1]. - **Polysilicon**: In the short - term, the price may continue to be strong, but price fluctuations may intensify. It is recommended to focus on short - term operations, and continuous attention should be paid to the actual start - up of the upstream and downstream of the industrial chain and the implementation of supply - side reform [1].
