China stocks rallied, with the Hang Seng up 0.8 percent and the Shanghai Composite up 2.3 percent overnight. After years of discussion, the Hong Kong Stock Exchange and Shanghai will finally open a formal stock trading link on Nov. 17.
Many mainland China firms already dual list in Hong Kong, mainly large state-owned enterprises, but this trading link will open up many more smaller companies.
Hong Kong investors will be able to buy and sell an additional 568 Shanghai-listed equities. Mainland investors will be able to buy and sell 268 Hong Kong-listed stocks. This opens up many domestic Chinese stocks for the first time.
Some fund managers were already allowed to invest in Chinese stocks through a quota system that was capped at $105 billion. But the new system will allow most investors to buy shares on the Shanghai Stock Exchange, opening up the $2 trillion market fully to foreign investment, though there will be some quotas on inflows into China that will still be applied.
