H share

H shares refer to the shares of companies incorporated in  mainland China that are traded on the Hong Kong Stock Exchange. Many companies float their shares simultaneously on the Hong Kong market and one of the two mainland Chinese stock exchanges in Shanghai or Shenzhen, they are known as A+H companies.

H shares are also held by a nominee service company "HKSCC Nominees Limited", which was owned by Hong Kong Exchanges and Clearing.

Price discrepancies between the H shares and the A share counterparts of the same company are not uncommon. A shares generally trade at a premium to H shares as the People's Republic of China government restricts mainland Chinese people from investing abroad and foreigners from investing in the A-share markets in mainland China.

Tsingtao Brewery was the first enterprise to offer H-shares when it became the first Chinese firm listed on the Hong Kong Stock Exchange in June 1993.
