1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report - On July 21, industrial silicon fluctuated strongly, with the main 2509 contract closing at 9,260 yuan/ton, an intraday increase of 4.99%, and the position decreased by 3,956 lots to 383,000 lots. The reference price of Baichuan industrial silicon spot was 9,297 yuan/ton, up 186 yuan/ton from the previous trading day. The price of the lowest deliverable 421 grade rose to 8,900 yuan/ton, and the spot discount widened to 185 yuan/ton. Polysilicon fluctuated higher, with the main 2509 contract closing at 45,850 yuan/ton, an intraday increase of 3.36%, and the position increased by 16,518 lots to 172,000 lots. The price of N-type polysilicon refeed material rose to 45,550 yuan/ton, and the price of the lowest deliverable silicon material rose to 45,500 yuan/ton, with the spot discount widening to 385 yuan/ton [2]. - Large industrial silicon manufacturers have not yet resumed production. The increase in the southwest is less than the decrease in the northwest. After the cancellation of the electricity price subsidy in Xinjiang, the cost support strengthening and the resumption of production expectation have entered a game, returning to the range - oscillation mode, with the upper limit being the position where the capacity enters the market after the profit in the southwest is repaired. The photovoltaic industry chain is boosted by the anti - involution policy, but there is no actual improvement in supply and demand. The bulls trade on the confidence that if the spot price does not fall, the futures price will not fall, and the overall support of the disk is relatively strong. After both industrial silicon and polysilicon rose to high levels, large - scale hedging positions entered the market, and there were cases where polysilicon long positions left the market with profits. The margin of polysilicon has been increased, further increasing the difficulty of chasing the rise. Attention should be paid to the PS/SI ratio and the policy implementation rhythm to see if there will be a new wave of upward pull after the callback [2]. 3.
