1. Report Industry Investment Rating - The investment strategy is to wait and see in the short term [3] 2. Core Viewpoints of the Report - The glass market lacks upward momentum before the Chinese New Year. The shipment speed of manufacturers has slowed down, and the middle and lower reaches have limited ability to digest high - level inventories. The market expects the production and sales to continue to weaken, and the price is expected to fluctuate between 1050 - 1070 yuan/ton. There is an opportunity to go long on glass and short on soda ash [3] 3. Summary According to the Directory 3.1 Investment Strategy - The main logic is that last week, the glass futures first fell and then rose, with a mid -阴线 on the weekly line. The supply remained unchanged, the market speculative demand weakened, and the overall inventory of the middle - stream was at a high level. The demand in the north was weak, and some processing plants will gradually have holidays. The production and sales may decline again before the Chinese New Year. The cost center of soda ash is expected to move down, and there is an opportunity to go long on glass and short on soda ash. The technical side shows that the bulls are slightly dominant, and the price is in a shock - adjustment stage [3] - The operation strategy is to wait and see in the short term [3][4] 3.2 Market Review - **Futures and Spot Prices**: As of January 23, the 5mm float glass market price was 1,010 yuan/ton (-10) in North China, 1,060 yuan/ton (0) in Central China, and 1,190 yuan/ton (0) in East China.

1. Report Industry Investment Rating - The investment strategy for the glass industry is to expect a weak and volatile trend [3]. 2. Core View of the Report - Last week, the glass futures weakened, with speculative sentiment cooling down. Although the inventory pressure of float glass factories has eased, the inventory in the middle - stream has reached a high level. The daily melting volume remained unchanged at 149,000 tons. The national factory inventory continued to decline due to the release of local speculative demand, and the inventory was further transferred to the middle and lower reaches. Before the Spring Festival, downstream enterprises will take holidays, and the decline of visible inventory is expected to slow down, with overall production and sales gradually declining. Macro - policy expectations have cooled down, and the market lacks substantial upward momentum. Technically, the short - side still has the upper hand, and the price is at a critical position in the adjustment stage. It is expected that the glass price will continue to operate in a weak and volatile manner, with the upper resistance level at 1130 - 1140 [3]. 3. Summary by Relevant Catalogs 3.1 Investment Strategy - The main logic is that the glass futures weakened last week. With the cooling of speculative sentiment, although the inventory pressure of float glass factories has eased, the middle - stream inventory has reached a high level. The daily melting volume remained stable, and the national factory inventory decreased due to speculative demand. Before the Spring Festival, downstream enterprises will rest, the decline of visible inventory will slow down, and production and sales will decline. Macro - policy expectations have cooled, and there is no substantial upward momentum in the market. Technically, the short - side dominates, and the price is in a critical adjustment position. It is expected that the glass price will be weak and volatile, with the upper resistance at 1130 - 1140. There is an opportunity to go long on glass and short on soda ash [3]. - The operation strategy is to expect a weak and volatile trend [3][4]. 3.2 Market Review: Spot Price Decline - As of January 16, the market price of 5mm float glass was 1,020 yuan/ton in North China (unchanged), 1,060 yuan/ton in Central China (+90), and 1,190 yuan/ton in East China (+10).

Report Industry Investment Rating - The investment rating for the glass industry is "Oscillating with a Bullish Bias" [2][91] Core Viewpoints of the Report - The glass futures strengthened last week, with the weekly line closing as a medium阳线. The cold - repair of multiple production lines at the end of the month, combined with Hubei's environmental protection rectification and gas - conversion plan, drove up the market due to positive supply - side expectations. Considering the supply - side pressure of soda ash and the expected contraction of float glass factory capacity, there is an opportunity to go long on glass and short on soda ash. After the New Year's Day, there are still expectations of some production lines shutting down, and the pre - Spring Festival restocking by spot - futures traders will boost production and sales. Technically, the bullish force is dominant, so the glass price is expected to maintain a short - term bullish trend [2][91] Summary According to the Table of Contents 1. Market Review: Rebound in the Market and Narrowing of the Basis - **Futures Price**: The glass 05 contract closed at 1,087 yuan/ton last week, up 39 yuan from the previous week. As of December 31, the spot prices of 5mm float glass were 1,000 yuan/ton (-20) in North China, 1,060 yuan/ton (0) in Central China, and 1,170 yuan/ton (-10) in East China [13] - **Price Difference**: As of December 31, the soda ash - glass price difference was 122 yuan/ton (-14). The basis of the glass 05 contract was -67 yuan/ton (-59) last Friday, and the 05 - 09 spread was -138 yuan/ton (-31) [14][18] 2. Supply - Demand Pattern: Decline in Daily Melting and Deterioration of Profits - **Profit**: The spot price of glass decreased, leading to a deterioration in gross profit. The cost of the natural - gas production process was 1,572 yuan/ton (-1), with a gross profit of -402 yuan/ton (-9); the cost of the coal - gas production process was 1,164 yuan/ton (+2), with a gross profit of -164 yuan/ton (-22); the cost of the petroleum - coke production process was 1,090 yuan/ton (-1), with a gross profit of -30 yuan/ton (+1) [22] - **Supply**: The daily melting volume of glass last Friday was 151,055 tons/day (-3,050).

The soda ash 05 contract closed at 1,209 yuan/ton (+25), and the basis of soda ash in Central China 05 was 91 yuan/ton (-25) last Friday. The ammonia - soda process cost of soda ash enterprises was 1,312 yuan/ton (-7), with a gross profit of -57 yuan/ton (+9); the co - production process cost was 1,738 yuan/ton (-29), with a gross profit of -21 yuan/ton (+21). As of December 31, the national factory - level inventory of soda ash was 1.4083 million tons (a month - on - month decrease of 30,200 tons), including 676,100 tons of heavy soda ash (a month - on - month decrease of 26,900 tons) and 732,200 tons of light soda ash (a month - on - month decrease of 3,300 tons). The apparent consumption of heavy soda ash last week was 454,300 tons, a week - on - week increase of 45,200 tons; the apparent consumption of light soda ash was 318,400 tons, a week - on - week increase of 11,100 tons. The production - sales ratio of soda ash was 108.54%, a week - on - week increase of 9.23% [58][60][79][88] 3. Investment Strategy: Short - Term Speculation, Oscillating with a Bullish Bias - **Main Logic**: The glass futures strengthened last week. The cold - repair of multiple production lines at the end of the month, combined with Hubei's environmental protection rectification and gas - conversion plan, drove up the market due to positive supply - side expectations. The supply decreased as 3 production lines shut down last week, with the daily melting volume decreasing by nearly 150,000 tons. The demand in the northern market decreased as terminal projects were coming to an end, and the end - of - year demand in the southern market was lower than last year, with poor restocking willingness among middle - and lower - stream enterprises. Most manufacturers focused on collecting payments and were bearish on the market next year. Given the supply - side pressure of soda ash and the expected contraction of float glass factory capacity, there is an opportunity to go long on glass and short on soda ash. After the New Year's Day, there are still expectations of some production lines shutting down, and the pre - Spring Festival restocking by spot - futures traders will boost production and sales. Technically, the bullish force is dominant [2][91] - **Operation Strategy**: Oscillating with a Bullish Bias [2][91]

1. Report Industry Investment Rating - The investment strategy for the glass industry is to be moderately bullish with short - term fluctuations [3]. 2. Core View of the Report - In the short - term, glass prices are expected to fluctuate and be moderately bullish around New Year's Day. Although the supply - demand situation of glass has deteriorated in the medium - to - long - term, there are short - term speculative opportunities due to the planned shutdown of multiple glass production lines around New Year's Day and the mid - stream replenishment before the Spring Festival. Technically, the bulls slightly dominate [3]. 3. Summary by Relevant Catalogs 3.1 Investment Strategy - The main logic is that last week, the glass futures rebounded slightly. With the clear cold - repair of multiple production lines at the end of the month and the rumored shutdown plans in Hubei, the expectation of supply reduction was hyped, slightly pushing up the market. The demand for thin - plate glass from home appliance orders supports the market, but most manufacturers focus on collecting payments and are bearish on next year's market. Given the high supply pressure of soda ash and the expected contraction of float glass production capacity, there is an opportunity to go long on glass and short on soda ash.
