Although weekend sales volume boosts the overall price of the industrial chain, it doesn't change the medium - term weak trend. PXN has short - term support starting from late August [7]. - PTA has a weak unilateral trend. Hold the mid - term position of long MEG and short PTA. Under low processing fees, pay attention to the support of unplanned production cuts on PTA processing fees, and conduct 1 - 5 reverse arbitrage. PTA supply decreases while demand increases, but high坯布 inventory and weak crude oil prices affect its performance [8]. - MEG has a weak and oscillating unilateral trend. Hold the mid - term position of long MEG and short PTA. Keep the 9 - 1 spread in the range of - 50 to 0 and pay attention to 1 - 5 reverse arbitrage.

Trump deployed two nuclear - powered submarines on August 1 in response to a "highly provocative statement" by a Russian senior official. If secondary sanctions or tariffs are implemented, 4 million barrels per day of oil could be removed from the market, pushing crude oil prices above $100 per barrel [3][5].

Views and Suggestions - **PX**: In August, there are no new PX maintenance plans, but some units are set to restart, while PTA device operating rates are expected to decline. PX supply - demand turns to a loose pattern, and the short - term suggestion is to short on rallies [5]. - **PTA**: The polyester factory operating rate is at a low level, and the willingness to hold raw materials has decreased. PTA factories sell at high - low basis, and the 09 contract has a bearish situation. It is recommended to conduct monthly spread long arbitrage at low levels [6]. - **MEG**: From a valuation perspective, the impact on the black sector is fading, and the overall valuation of coal - chemical industry is falling. The domestic device operating rate will continue to rise. It is recommended to conduct monthly spread long arbitrage at low levels, while being vigilant about the long - squeeze situation [7].
