Although this year's cotton production is a bumper harvest, the expected increase may be less than previously thought. The market has entered the off - season after the peak season.

1. Report Industry Investment Rating No information provided in the report. 2.

Although this year's cotton production is a bumper harvest, the expected increase may be less than previously thought. The demand side is entering a relatively off - season after the peak season, with average recent orders. Considering these factors, Zhengzhou cotton is likely to fluctuate, with limited upside and downside potential. Additionally, Sino - US trade negotiations and the expiration of the Sino - US tariff agreement in November may have a significant impact on the market [5]. - It is expected that the future trend of US cotton will mostly be in a sideways pattern, while Zhengzhou cotton is expected to show a slightly stronger sideways movement.
