Chinese AI firms MiniMax Group and Knowledge Atlas Technology – better known as Zhipu AI – will join the Hang Seng Tech Index next month.

Their inclusion follows investor criticism that the city’s primary technology gauge has underperformed by missing out on the global artificial intelligence boom.
Concurrently, Shanghai-based courier J&T Global Express, lightweight metal giant Aluminum Corp of China and Beijing-founded global drug firm BeOne Medicines will join the benchmark Hang Seng Index. The additions are part of a long-term plan by the compiler to increase the number of blue-chip constituents to 100.

The three companies will be added to the gauge after the market close on June 5, increasing the tally of index constituents to 93 from 90 currently, Hang Seng Indexes Co said in a statement on Friday after the market closed. Meanwhile, there will be no deletions, it said.

Meanwhile, Hansoh Pharmaceutical and Akeso will join the Hang Seng China Enterprises Index of mainland Chinese companies trading in Hong Kong, according to the statement.
