1. Report Industry Investment Rating - For industrial silicon, the unilateral strategy is rated as neutral, while cross - period, cross - variety, spot - futures, and option strategies are not recommended [3] - For polysilicon, in the short - term, a range - trading strategy is suggested, and cross - period, cross - variety, spot - futures, and option strategies are not recommended [8] 2. Core Viewpoints - Industrial silicon futures prices are oscillating weakly, mainly affected by overall commodity sentiment. The current fundamentals have little change, and the spot price has declined [2][3] - Polysilicon futures prices are in wide - range oscillation, mainly influenced by anti - involution policies. In the short - term, they are expected to maintain wide - range oscillation, and it is suitable to buy on dips in the medium - to - long - term [4][8] 3.

The overall industry start - up of monomer plants was at a relatively high load, and the overall output was relatively stable compared with last week, but the implicit pressure on enterprises increased. In July 2025, the export volume of China's primary - form polysiloxane was 46,400 tons, a month - on - month decrease of 6.64% and a year - on - year decrease of 7.01%. From January to July 2025, the cumulative export volume was 325,000 tons, a year - on - year increase of 1.85% [3] Strategy - Unilateral: Neutral - Cross - period: None - Cross - variety: None - Spot - futures: None - Option: None [3] Polysilicon Market Analysis - Futures: On August 20, 2025, the main contract 2511 of polysilicon futures oscillated widely, opening at 51,700 yuan/ton and closing at 51,875 yuan/ton, a change of - 0.52% from the previous trading day. The position of the main contract reached 150,086 (137,977 in the previous trading day) lots, and the trading volume on that day was 704,931 lots [4] - Spot: Polysilicon spot prices remained stable.
