A-share pricing needs to be right for overseas investors

"Some overseas investors could not understand why some companies suspended trading during the stock price plunge in the summer," Yu added. "Once (overseas) investors become more familiar with A-share logic, there will be more confidence in the market."

Overall, the Shanghai-Hong Kong Stock Connect link has been a success. It generated turnover of more than $320 billion in October, according to Charles Li Xiaojia, CEO of Hong Kong Exchanges & Clearing Ltd, in a blog post last week.

"The link is like a bridge and its success is not measured on short-term activities but long-term results," Li said.

Kinger Lau at Goldman Sachs (Asia) LLC was just as bullish about the cross-border connection. Lau pointed out that the link has opened China's capital markets to global investors.

"What happened in the past year can be an inspiration for similar links that might be introduced in the near future, such as the Shenzhen-Hong Kong connection, which could be launched in March or April of next year," Lau said.
