1, the decline in crude oil shows that demand is decreasing, macroeconomic growth is slowing down, and the general trend is unfavorable. 2. When crude oil rises, the company said that it would take measures to increase its inventory in advance, which is equivalent to the company buying low-priced raw materials in advance. The price increase of crude oil and asphalt is beneficial to the company. So now the price of crude oil is falling. If the company mismanages and digests the high-priced inventory in time, the price of asphalt will fall with the decline of oil price, which is equivalent to the company buying high-priced raw materials in advance, which is also unfavorable to the company in the short term.
