On May 21, Chalco (China Aluminum Corporation) fell 3.02% in regular trading, trading at HK$10.59/share, with trading volume of HK$344 million. The decline marks a continuation of the stock's recent downward trend amid broad aluminum sector weakness.

On the news front, the aluminum sector remained under sustained selling pressure, with peer stocks China Hongqiao falling 2.97%, Xingfa Aluminum down 1.71%, and Nanshan Aluminum International declining 0.93%. At the macro level, elevated U.S. April PPI data fueled expectations of further Fed rate hikes, suppressing upside potential for non-ferrous metal prices. Analysts noted that downstream demand is gradually transitioning into the off-season, leaving the aluminum market in a pattern of strong supply and weak demand.

On the institutional front, CITIC Securities Asset Management sold 12.63 million shares on May 15 at an average price of approximately HK$10.62 per share, reducing its stake to 4.82%. Meanwhile, BlackRock trimmed its long position from 9.18% to 8.40%, intensifying market selling pressure through consecutive net capital outflows.
