Market Supervision Division

This division controls and supervises clearing houses and stock market activities.

Intermediaries and Investment Products Division

It defines the approval conditions relating to the financial integrity of listed intermediaries.

This is also a key point in the difference between Hong Kong and China stocks.
  • Secondly, the Hong Kong stock market is also known for being highly volatile most of the time. This is why it attracts many investors, especially those who use CFDs and ETFs. Not only that, but there are also binary options users looking to invest in the benchmark Hang Seng index.
