(Yicai Global) Sept. 22 -- Hang Seng Indexes has introduced a new stock market index the Hang Seng Shanghai-Shenzhen-Hong Kong (Selected Corporations) 300 Index, which aims to mirror the overall stock market performance of the 300 largest listed companies by total market caps that operate in the Chinese mainland, Hong Kong and Macau, the indexer announced yesterday.

The index company cherry picked the 300 firms based on main business location and market liquidity, in addition to market cap. Each of those selected must have derived over half of their income, assets or profits from the mainland, Hong Kong or Macau in the most recent fiscal year and average at least CNY20 million (USD2.9 million) or HKD20 million (USD2.6 million) in daily turnover in the last six months.

Shares of those listed in both Hong Kong and the mainland only include those traded in the mainland.

Famous companies including Alibaba Group Holding, JD.Com, Tencent Holdings, Meituan Dianping, Evergrande Group, Bank of China Hong Kong and Hong Kong Exchange and Clearing have had their Hong Kong-listed shares included, while Kweichow Moutai, BOE Technology Group, Contemporary Amperex Technology, BYD and Beijing-Shanghai High Speed Railway have also had their domestically-traded A-shares inducted.
