1. Report Industry Investment Rating - The report does not provide an industry investment rating [1][2][3][4] 2. Core Viewpoints of the Report - In the short - term, PVC's trend is strong due to factors like export rush, the Minamata Convention, stock funds, and future production cut expectations. However, the PVC market has a high - output and high - inventory structure that is difficult to change. Before the 03 contract, the futures contracts face a pattern of high operation and weak demand. The expected significant inventory build - up during the Spring Festival and the contango structure limit the market's trading space for low - valuation factors, and the rapid recovery of the disk profit is not conducive to future production cuts and maintenance in the chlor - alkali industry. Also, PVC warehouse receipts are at a high level, and there is still significant pressure on long - position holders to take delivery. Overall, in 2026, the production cut in the maintenance peak season on the supply side may exceed expectations, which is beneficial for the profit repair of the chlor - alkali industry. Before the Spring Festival, the optimistic expectations are difficult to disprove, and the disk continuously raises the valuation. But if manufacturers do not cut production later, the market will still trade on delivery pressure and excessive forward premium [3] 3. Summary by Relevant Catalogs 3.1 Fundamental Tracking - The 05 - contract futures price is 5063, the East China spot price is 4780, the basis is - 283, and the 5 - 9 spread is - 122. The domestic PVC spot market fundamentals remain dull. Industry supply is slowly increasing, but demand is gradually slowing due to the festival, and the inventory continues to accumulate. The disk was significantly pushed up in the afternoon due to carbon - emission - related remarks, but the spot market transactions were light, and the increase in spot prices was lower than that of the disk [2] 3.2 Market Condition Analysis - Short - term factors support the strong PVC trend, but the high - output and high - inventory structure persists. Before the 03 contract, there is a high - operation and weak - demand pattern. The expected inventory build - up during the Spring Festival and the contango structure limit trading space, and the rapid profit recovery is not conducive to production cuts. PVC warehouse receipts are high, and there is delivery pressure. In 2026, supply - side production cuts in the maintenance peak season may exceed expectations, and before the Spring Festival, optimistic expectations are hard to disprove, but if there are no production cuts later, the market will focus on delivery pressure and forward premium [3] 3.3 Trend Intensity - The PVC trend intensity is 0, with the value range of [- 2, 2], where - 2 means most bearish and 2 means most bullish [4]
