The connection of Shenzhen and Hong Kong stock markets means more free flow of capital. Once the connection is made, mutual stock market access will be available between Hong Kong and Shenzhen through a dual-bound trading link.

The whole program will be ready after four months, after authorities agreed to settle differences on clearance and stock exchange policies. Senior officials from the Hong Kong Exchanges and Clearing Limited expressed hope that the program could enhance connectivity and provide a reliable channel for investment for both HK and mainland markets.

"There are several key points for the Shenzhen-Hong Kong Stock Connect program. For the first time, Hong Kong sees 800 new shares in Shenzhen. Second, there are over one hundred stocks added to the south bond for the Shenzhen connect. Third, the aggregate quota has been completely abandoned. And last, this is the first time the Shenzhen Growth Enterprises Market and Exchange Traded Fund or ETF will be included," Li Xiaojia, chief executive of Hong Kong Exchanges and Clearing Limited, said.
