The 01 contract on the futures market offers a risk - free arbitrage opportunity for imports, and it is believed that the 01 contract will end up with high inventory, so it is advisable to do a 1 - 5 reverse spread on rallies [3]. - For polyethylene, the inventory of Sinopec and PetroChina is neutral year - on - year. Upstream Sinopec and PetroChina and coal - chemical enterprises are destocking, social inventory is flat, downstream raw material and finished - product inventories are neutral. The overall inventory is neutral. The 09 contract basis is about - 110 in North China and - 50 in East China. The overseas markets in Europe, America and Southeast Asia are stable. The import profit is around - 200 with no further increase for now. The price of non - standard HD injection molding is stable, other price differentials are fluctuating, and LD is weakening.

Under the background of over - capacity, the 01 contract is expected to face moderate to excessive pressure. If exports continue to increase or there are more PDH plant overhauls, the supply pressure can be alleviated to a neutral level [3]. - For PVC, the basis of the 01 contract is maintained at - 270, and the factory - pickup basis is - 480. The downstream operating rate is seasonally weakening, and the willingness to hold goods at low prices is strong. The inventories of middle and upstream enterprises are continuously accumulating. The summer maintenance of Northwest plants is seasonal, and the load center is between the spring maintenance and the high - production period in Q1. In Q4, attention should be paid to the commissioning and export sustainability. The recent export orders have declined slightly. The coal market sentiment is positive, the cost of semi - coke is stable, and the profit of calcium carbide is under pressure due to PVC overhauls. The FOB counter - offer for caustic soda exports is 380. The PVC comprehensive profit is - 100. Currently, the static inventory contradiction is accumulating slowly, the cost is stable, the downstream performance is mediocre, and the macro situation is neutral.

The demand side is stable, and the overall inventory is flat but with local increases. In the short term, the price may be supported by trading activity and basis, but inventory pressure needs attention. It is expected that the price will fluctuate and consolidate at the current level [37] Group 3: Summary by Directory 1.
