Hang Seng Index Quarterly Review: Blue-Chip Roster Grows to 95 Stocks
Hang Seng Indexes Company has released the results of its quarterly review for the period ending June 30, 2026. The most notable change is the expansion of the flagship Hang Seng Index (HSI), which will increase its number of constituents from 93 to 95.
New Entrants: Spotlight on Semiconductors and Advanced Manufacturing
The two companies joining the HSI are Hua Hong Grace Semiconductor Manufacturing Co., Ltd. (01347.HK) and Weichai Power Co., Ltd. (02338.HK). The inclusion of Hua Hong Grace underscores the market's continued focus on the strategic semiconductor sector. Weichai Power's addition strengthens the index's representation in the industrial and manufacturing space.
Concurrent Reshuffle for the Hang Seng Tech Index
The Hang Seng Tech Index (HSTECH) will maintain its count of 30 constituents but will see one change. Tianchi Digital Technology Co., Ltd. (09903.HK), a company focused on AI chips, will be added to the index, while Tongcheng Travel Holdings Limited (00780.HK) will be removed. This adjustment highlights the index's responsiveness to evolving technology trends.
Implementation Timeline and Market Implications
All constituent changes for the HSI, Hang Seng China Enterprises Index, HSTECH, and Hang Seng Composite Index will take effect after the market close on Friday, September 4, 2026, and will be implemented from the start of trading on Monday, September 7, 2026.
The review is likely to trigger portfolio rebalancing by passive funds that track these benchmarks. For the newly added companies, inclusion typically brings increased liquidity and investor attention.
