A-share (mainland China) should not be confused with Class A share.
A-shares, also known as domestic shares, are shares that are denominated in renminbi and traded in the Shanghai and Shenzhen stock exchanges,[1] as well as the National Equities Exchange and Quotations.
These are in contrast to B-shares that are denominated in foreign currency and traded in Shanghai and Shenzhen, as well as H shares, that are denominated in Hong Kong dollars and traded in the Stock Exchange of Hong Kong.
A-shares are generally owned by domestic investors. As of 2023, foreign investors own only 3-5% of China's A-shares equity and bond market.[2]
