On July 23, the Hong Kong stock market's aluminum sector experienced a broad-based surge.
By the market close, CHALCO (02600.HK) had risen by 6.28%, NANSHAN AL INTL (02610.HK) was up 3.89%, CHINAHONGQIAO (01378.HK) gained 3.37%, and CHUANGXIN IND (02788.HK) advanced 3.63%, with nearly all stocks in the sector finishing in positive territory.
This rebound in aluminum stocks is not merely a short-term speculative move, but the result of multiple favorable factors converging.
First, industry inventories have been consistently declining, leading to a stronger-than-expected recovery during the traditionally slow season.
Analysis indicates that while China is currently in the traditional low-demand season for primary aluminum, market demand has shown unexpected resilience.
Inventories have continued to fall against the seasonal trend, resulting in tight availability of spot material in the market and providing solid support for the floor price of aluminum.
Second, escalating geopolitical risks are increasing the supply-side premium for the sector.
Recent tensions in the Middle East have raised market concerns about potential disruptions to the global aluminum supply chain from regional conflicts.
Coupled with the ongoing implementation of bauxite export control policies in Guinea, uncertainty regarding the supply of this key upstream raw material has significantly increased.
These persistent supply-side constraints are further elevating the risk premium priced into aluminum, driving up valuations across the sector.
Examining the Broader Industry
Looking at the wider industry, the supply-demand dynamics for primary aluminum are continuously improving, with a clear long-term growth narrative.
On the supply side, China strictly enforces a production capacity ceiling policy for primary aluminum, leaving the industry with very low supply elasticity and limited potential for incremental output.
On the demand side, burgeoning sectors like new energy vehicles and photovoltaics are generating sustained and growing demand for aluminum products.
This effectively offsets the pressure from weak demand in the traditional real estate sector, allowing the overall industry to enter a favorable state of tight supply-demand balance.
Financial Performance Underpins the Move
From an earnings perspective, leading companies such as CHALCO and CHINAHONGQIAO possess strong profit elasticity during periods of rising aluminum prices, thanks to their low-cost production advantages and comprehensive, integrated industrial chains.
For the first half of 2026, CHALCO reported net profit attributable to shareholders of 11.2 to 12.2 billion yuan, representing a year-on-year increase of 58% to 73% and marking its best-ever profit level for the same period.
CHINAHONGQIAO is expected to report a 39% increase in net profit compared to the same period in 2025, confirming the realization of the industry's favorable conditions.
Outlook for the Sector Rally
Overall, the current rebound in Hong Kong's aluminum sector is the result of multiple factors aligning, including fundamental support from inventory drawdowns and a tight supply-demand balance, amplified by geopolitical event-driven momentum.
This suggests the rally may have considerable sustainability.
Going forward, the market should closely monitor the pace of inventory reduction, the potential upside for aluminum prices, and the strength of the recovery in downstream end-user demand.
It is also noteworthy that preparations for the upcoming selection of the "Top 100 Hong Kong Stocks" are progressing in an orderly manner.
As core leaders in China's primary aluminum industry, CHALCO and CHINAHONGQIAO, with their robust industrial competitiveness and operational strength, have been regular fixtures on past Top 100 lists.
Given their impressive financial performance, whether these two giants can once again secure a place in the latest ranking remains a key topic of ongoing market discussion.
