Report Industry Investment Rating - Not provided Core View of the Report - The view is to wait for a long - entry opportunity for MEG, but the downside space may also be large. The recommended contract is eg2505. The logic is that although MEG inventory slightly accumulated in Q1 2025, the medium - to - long - term supply - demand driver is still upward under the current low port inventory. However, the cost of crude oil and coal prices has moved downward weakly. It is recommended to go long at low prices after the cost side stabilizes [4]. Summary by Relevant Catalogs 1.
