Report Summary 1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Core Views - **Methanol**: High imports are being realized, inventory accumulation has begun, and the futures price is undervalued. It is currently in a period of negative factors being realized. With unstable macro - environment and weak methanol prices in Europe and the US, the unilateral direction is hard to determine. Given the low valuation, it is advisable to consider buying at low prices [1]. - **Plastic (Polyethylene)**: The overall inventory of polyethylene is neutral. The 09 basis is around 0 in North China and +120 in East China. Import profits are around - 400 with no further increase for now. The domestic linear production has increased month - on - month in June. Attention should be paid to the LL - HD conversion and new device commissioning [2]. - **PP (Polypropylene)**: The upstream and middle - stream inventories of polypropylene are decreasing. The basis is +100, non - standard price differences are neutral, and import profit is around - 500. Exports have been good this year. The supply in June is expected to increase slightly month - on - month. The 09 contract is expected to face moderate to excessive supply pressure, which can be alleviated if exports continue to grow or PDH device maintenance increases [2]. - **PVC**: The basis remains at 09 - 150, and the downstream start - up rate is seasonally weak. The inventory reduction of the middle and upstream has slowed down. Attention should be paid to production commissioning and export sustainability from July to August. The current static inventory contradiction is accumulating slowly, costs are stable, and the downstream performance is mediocre [2]. 3.

1. Report Industry Investment Rating - No information provided in the content. 2. Core Viewpoints of the Report - After the holiday, polysilicon showed a weak and volatile trend. The main contract 2506 closed at 36,410 yuan/ton, with an intraday decline of 2.39%, and the open interest decreased by 510 lots to 53,756 lots. The SMM N-type polysilicon price was 40,500 yuan/ton, and the spot premium over the main contract widened to 4,090 yuan/ton. Industrial silicon also showed a weak and volatile trend. The main contract 2506 closed at 8,325 yuan/ton, with an intraday decline of 2.57%, and the open interest increased by 12,934 lots to 17,950 lots. The Baichuan industrial silicon spot reference price was 9,637 yuan/ton, down 128 yuan/ton from the last trading day before the holiday. The price of the lowest deliverable 553 grade dropped to 8,650 yuan/ton, and the spot premium widened to 280 yuan/ton. Before the holiday, traders cleared their inventories and pressured prices, and the downstream's willingness to stock up was lower than in previous years. After the holiday, the downstream demand still faced the pressure of a slowdown. Industrial silicon was affected by the negative feedback from the downstream and was difficult to get out of the bottom-finding rhythm. The adjustment flexibility of polysilicon production was relatively high, and the space for a sharp decline after the holiday was relatively limited compared with industrial silicon, mainly showing a narrow correction. Opportunities for the convergence of the spread between near and far months could be considered. Attention should be paid to whether large-scale infrastructure or mandatory photovoltaic installation assessment policies will be newly introduced after the decline of distributed photovoltaics, which may trigger an oversold rebound [2]. 3.
