Report Summary 1. Report Industry Investment Rating No information provided. 2. Core Viewpoints - Ethylene glycol's recent fundamental drivers are limited. It was relatively resistant to price drops due to low inventory, but with the cooling of the chemical sector sentiment and lack of policy support, it has seen a compensatory decline.

In the short - term, it oscillates in the 4350 - 4550 range, mainly following the cost side and commodity sentiment. It is recommended to buy on dips within the range. In the long - term, the performance of the downstream polyester peak season needs to be observed, and long positions can be combined with selling out - of - the - money near - month call options for covered operations [3]. 3.
