Report Industry Investment Rating No relevant content provided. Core Viewpoints - The market sentiment is cautious, and the black commodity market shows a weak and volatile trend [1]. - For glass and soda ash, the downstream procurement is cautious, with glass opening high and closing low, and soda ash showing a narrow - range oscillation [1]. - For silicon - manganese and silicon - iron, the supply side is frequently disturbed, with silicon - manganese rising strongly and silicon - iron moving in a volatile manner [3]. Summary by Related Catalogs Glass and Soda Ash Market Analysis - Glass: The glass futures opened high and closed low yesterday. The spot market had dull trading, and the downstream procurement sentiment was average. This week, the national weekly average price of float glass was 1,251 yuan/ton, a decrease of 17.35 yuan/ton compared to the previous week. The enterprise operating rate was 75.34%, an increase of 0.34%. The manufacturer's inventory was 67.769 million heavy boxes, a decrease of 0.46% [1]. - Soda Ash: The soda ash futures showed a narrow - range oscillation yesterday. The spot market demand was average, mainly for rigid - demand procurement. This week, the capacity utilization rate of soda ash was 78.63%, a decrease of 1.64%. The output was 663,800 tons, a decrease of 2.04%. The inventory was 1.6768 million tons, a decrease of 2.06% [1]. Supply - Demand and Logic - Glass: Recently, the glass output has slightly increased. Due to the insufficient recovery of real - estate and deep - processing demand, the restocking intensity and sustainability are weak. Although the glass inventory has slightly decreased, the de - stocking pressure is large, and the price lacks upward momentum. In the later high - temperature and rainy season, it is not conducive to glass storage, and enterprises may have a stronger intention to reduce prices for sales and inventory reduction [1]. - Soda Ash: Affected by the increase in alkali plant maintenance, the recent soda ash output has declined but remains in a loose state. Currently, the growth of the photovoltaic industry has slowed down, and the room for increasing soda ash demand is limited. The de - stocking pressure is still large. Attention should be paid to the summer maintenance of alkali plants and the progress of annual new - capacity production [1]. Strategy - Glass: Volatile [2] - Soda Ash: Weakly volatile [2] Silicon - Manganese and Silicon - Iron Market Analysis - Silicon - Manganese: The market oscillated upward yesterday, with an increase of 14,243 open positions and a rapid expansion of trading volume. In the spot market, the mainstream steel tenders started to quote, and the market enthusiasm was average. Factories basically stopped quoting. Affected by industry profits, the silicon - manganese output continued to decline and was at a low level in previous years. The hot - metal output declined from a high level, and the demand for silicon - manganese weakened. The silicon - manganese manufacturer's inventory and registered warrants were at a high level, suppressing the silicon - manganese price. However, considering that the manganese ore port inventory was at a low level, the continuous decline in manganese ore prices had dragged down shipments, which supported the alloy cost. Attention should be paid to the supply side of manganese ore in the later stage [3]. - Silicon - Iron: The silicon - iron futures moved in a volatile manner yesterday, with a decrease of 7,875 open positions. In the spot market, the silicon - iron market was weak, with mostly cautious operations and little change in transaction prices. Against the background of enterprise losses, the silicon - iron output remained at a medium - low level. The hot - metal output reached the peak and then declined, and the demand for silicon - iron began to weaken. The manufacturer's inventory continued to be depleted, and the downstream enterprise inventory remained at a low level. The silicon - iron production capacity was relatively loose, and the short - term price was dragged down by costs. Attention should be paid to the impact of electricity price changes and industrial policies on the black sector in the future [3]. Strategy - Silicon - Manganese: Volatile [4] - Silicon - Iron: Volatile [4]
