After the closing of the Third Plenary Session of the Eighteenth Central Committee, the A-share market danced with different interpretations. At the same time, the international economy is slowly recovering, which also brings more investment opportunities to the capital market. As the basic pillar industry of the national economy, the chemical sector will also get a piece of the cake in this feast. The end of January and the beginning of February are the time points for the publication of Document No. 1 every year, and the capital market also tends to set off related hype. Therefore, eco-agriculture has recently become a hot spot in the market again. In addition, a week ago, the multinational giant Dismann announced a price increase for its vitamin E products. Judging from the current situation of continuous price increase for related products, the domestic vitamin market in the future deserves attention. Just last week, 14 months of domestic pyridine anti-dumping cases were settled, and the future domestic pyridine market pattern is expected to change.
