CHALCO's stock fell sharply by 5.17% intraday, extending recent losses for the aluminum producer.

The decline is attributed to broad-based weakness in the aluminum sector, which has been under sustained selling pressure across multiple trading sessions. Peer companies in the sector have also experienced significant declines, reflecting a sector-wide correction that is outweighing individual company performance.

Despite CHALCO reporting strong first-quarter fundamentals with net profit up 56.35% year-over-year, and positive corporate developments including increased holdings by BlackRock and authorization for share buybacks, the broader aluminum sector downturn has continued to negatively impact the stock's near-term performance.
