新能源及有色金属日报：减仓引发盘面扰动，关注持仓变动风险-20250529

1. Report Industry Investment Rating - No specific industry investment rating is provided in the report. 2. Core Views - For industrial silicon, in the context of expected supply increase, low demand, weakened cost support, high industry inventory, and a large number of warehouse receipts, the industry's fundamentals are weak, trapped in a dilemma of "cost collapse + lagging capacity clearance", and prices are continuously hitting new lows. In the short term, there is still no positive driving force, and the market is expected to continue to fluctuate weakly and explore the bottom. Attention should be paid to the volatility risk caused by short - covering and position reduction [2]. - For polysilicon, since May, many enterprises have carried out maintenance or postponed resumption of production, and the short - term supply pressure has been slightly relieved, but the downstream demand is generally low. The current polysilicon market is in a situation of weak supply and demand, and the price trend is highly uncertain. As the first delivery approaches, the long - short game in the market intensifies, and there is a lack of demand driving force in the short term. Prices are expected to fluctuate widely, and range operation is recommended [7]. 3.
