Report Summary 1. Report Industry Investment Rating - The report suggests a temporary wait - and - see approach or a long - position thinking [3] 2. Core View - On the supply side, domestic and foreign zinc ore imports are rising, the growth of zinc ore processing fees is slowing down, the sulfuric acid price has increased significantly, smelters have large profit margins and increased production enthusiasm. New production capacities are being released, and refined zinc production has reached a high level. However, overseas zinc ore is tight, import losses continue to expand, the inflow of imported zinc decreases, and the export window is expected to open.

Domestic social inventories have increased, post - holiday market demand remains weak, and the spot premium is at a low level. LME inventories continue to decline, the spot premium has reached a 27 - year high, and the tight situation has intensified [3] 3.

1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints of the Report - The zinc market shows a neutral - weak strength analysis, with a continuous inventory accumulation trend [2][3] - Domestic zinc supply is expected to increase. Although there is a slight improvement in consumption, it is relatively limited. The inventory accumulation trend may continue, and prices lack upward momentum. In the medium - to - long term, a short - selling approach on rallies is recommended [5] - The contradiction between domestic and foreign markets is prominent, with an increasingly obvious pattern of stronger foreign and weaker domestic zinc prices. There is an opportunity for the export window to open in the fourth quarter, and it is advisable to hold short - to - medium - term (within a quarter) positive spread positions cautiously [5] 3.
