Core Views Glass and Soda Ash - Soda ash: Production is gradually recovering to a high level, and the weekly output has returned to around 73 - 740,000 tons. There has been a slight reduction in inventory, but with the increase in production, there is still expected to be inventory pressure. The market for soda ash remains under pressure due to the lag in photovoltaic resumption, and the futures market is expected to continue its weak oscillation in the future [1]. - Glass: The spot market is weak, and the macro - level is bearish, which jointly puts pressure on glass prices. The 05 contract is affected by the expansion of the delivery warehouse in Hubei and is showing a weak performance. The 09 contract has a relatively low price, and the market has expectations for stimulus policies, but there is currently no short - term driver [1]. Industrial Silicon The spot price of industrial silicon continues to decline, and the futures price has reached a new low. Supply has a slight increase, demand remains weak, and downstream prices are showing a downward trend, which drags down the price of industrial silicon. There are concerns about inventory accumulation, and the price fluctuation range is further adjusted to 8,500 - 10,500 yuan/ton [3]. Polysilicon The polysilicon futures price has fallen sharply, and the current spot price is at a significant premium to the futures price. There is support from downstream demand in April, but polysilicon inventory has not continued to decline, and downstream prices are starting to weaken. The futures price is expected to have limited room for further decline [4]. Natural Rubber Domestic rubber - producing areas are entering the new tapping season, and overseas areas are also gradually starting to tap after the Songkran Festival. The cost support for rubber prices has weakened. On the demand side, the inventory of semi - steel tires continues to increase, and enterprises are reducing production to control inventory. Short - term rubber prices are expected to face significant pressure [5]. 3.
