1. Report Industry Investment Ratings No investment ratings are provided in the reports. 2. Core Views Glass and Soda Ash - Macro - warming and coking coal accident news drove the soda ash futures to rebound. Fundamentally, weekly production rebounded significantly, and the inventory continued to build up. With current weekly production, demand was significantly in excess. Recently, spot sales were weak. In the medium - term, after the second - quarter PV glass installation rush, PV glass capacity growth slowed, float glass capacity remained flat, and there was still pressure on supply - demand in the future, with potential for further cold - repair. Overall, there was no growth expectation for soda ash demand. Without actual capacity exit or load reduction, inventory would face more pressure. Track policy implementation and soda ash plant load adjustment [1]. Natural Rubber - Persistent rainy weather in internal and external production areas disrupted upstream supply, keeping raw material prices high. The de - stocking rate of spot inventory in Qingdao slowed, and with the incremental release of alternative plantings in Yunnan, China's social inventory increased, intensifying market bearish sentiment. In terms of demand, although agents' purchase volume might slightly increase at the end of the month to meet monthly targets, downstream buyers mainly continued regular restocking. Adverse external factors might slow down trading in the Beijing - Tianjin - Hebei region and potentially halt some mining and engineering operations, negatively affecting replacement demand. Affected by the Fed's dovish stance, market sentiment improved, driving up rubber prices, but prices were expected to fluctuate within a range. The reference range for the 01 contract was 15,000 - 16,500. Monitor raw material supply during the peak production season in major producing areas and consider short - selling if supply is smooth [3]. Polysilicon - In August, polysilicon supply and demand both increased, but the supply growth rate was higher, still facing inventory build - up pressure. Due to the previous sharp price increase above the full - cost level and the addition of two new delivery brands on the Guangzhou Futures Exchange, future warehouse receipts were expected to increase. Currently, the price would mainly fluctuate at a high level, with the lower limit of the price range rising to 47,000 yuan/ton and the upper limit between 58,000 - 60,000 yuan/ton. Consider buying on dips. When the price is high, buy put options during low - volatility periods to short. Technically, the futures price might choose a direction to break out in a converging triangle, and consider buying straddle options when volatility is low. Pay attention to position control and risk management [5]. Industrial Silicon - From the cost side, raw material prices started to rise, and electricity prices in the southwest region would gradually increase during the dry season, raising the cost center of industrial silicon. Although industrial silicon production increased month - on - month, there were also news of capacity clearance, with small furnaces potentially shutting down. In August, supply and demand both increased, maintaining a tight balance. If some capacity is cleared in the long - term, supply pressure will ease. Strategically, consider buying on dips. However, note that as production increases, inventory and warehouse receipt pressure are emerging. The main price fluctuation range might be 8,000 - 9,500 yuan/ton, and hold long positions established at the previous low of 8,000 - 8,500 [6]. 3.
