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.

冷修环保炒作短期偏强运行:玻璃一月报-20260105
Chang Jiang Qi Huo· 2026-01-05 05:52
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).

On December 30, the operating rate of LOW - E glass was 44.1% (-0.8%). In mid - December, the number of available days for glass deep - processing orders was 9.7 days (-0.4) [34] - **Automobile Demand**: In November, China's automobile production was 3.532 million vehicles, a month - on - month increase of 0.173 million and a year - on - year increase of 0.095 million; sales were 3.429 million vehicles, a month - on - month increase of 0.107 million and a year - on - year increase of 0.113 million. The retail volume of new - energy passenger vehicles was 1.321 million, with a penetration rate of 59.3% [44] - **Real Estate Demand**: In November, China's real estate completion area was 45.9293 million square meters, a year - on - year decrease of 25%; the new construction area was 43.9531 million square meters (-28%); the construction area was 31.2717 million square meters (-42%); the commercial housing sales area was 67.1974 million square meters (-18%). From December 22 to 28, the total commercial housing transaction area in 30 large - and medium - sized cities was 3.44 million square meters, a month - on - month increase of 35% and a year - on - year decrease of 23%. The real estate development investment in November was 502.82 billion yuan, a year - on - year decrease of 31% [49] - **Import and Export**: In November, China imported 310,900 weight boxes of float glass (a year - on - year increase of 27%) and exported 1.69 million weight boxes (a year - on - year increase of 47%) [51] - **Soda Ash - Cost Side**: The spot prices of heavy soda ash were 1,325 yuan/ton (0) in North China, 1,250 yuan/ton (0) in East China, 1,300 yuan/ton (0) in Central China, and 1,450 yuan/ton (0) in South China. 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.

Core Views - The chemical market is generally under pressure from demand, with different products facing various supply - demand situations. Positive and negative factors coexist, and investors need to pay attention to specific product trends and relevant influencing factors [2][3][5][6][7][8] 3. Summaries by Directory Olefins - Polyolefins - Propylene futures had narrow intraday fluctuations. The demand is weak, but the maintenance of Binzhou PDH device may support price stabilization [2] - Plastic and polypropylene futures declined. The supply of polyethylene increased due to reduced maintenance and new production, while demand weakened. Polypropylene faced supply pressure from new capacity and reduced maintenance, and demand was limited by low profit [2] Pure Benzene - Styrene - Pure benzene futures oscillated around 5,500 yuan/ton. The port inventory increased, and there are medium - term negatives. The strategy is mainly month - spread reverse arbitrage [3] - Styrene futures were weak. The cost support was insufficient, and the high inventory pressure continued [3] Polyester - PX and PTA prices fluctuated. Supply increased, and there was a risk of inventory accumulation. The strategy is reverse arbitrage [5] - Ethylene glycol production decreased slightly, but inventory increased. The supply pressure is high, and the strategy is reverse arbitrage [5] - Short fiber had a good spot pattern but may face inventory accumulation in mid - to late November.
