Nothing has changed at China Vanke except where its shares are trading, but that's enough to cause a 10 per cent bump.
China's largest residential property developer delisted from the Shenzhen exchange earlier this month and has now debuted in Hong Kong.
Immediately, the shares jumped to HK$13.66.
Vanke is the third major company to move its listing away from the mainland, where stock markets are sleepy and increasingly struggling to maintain investor enthusiasm. China International Marine Containers was the first, in December 2012, followed by Livzon Pharmaceutical in January.
Among dual-listed companies, shares traded in Hong Kong hit their most expensive level compared to those in Shanghai since 2006 earlier this month, reflecting the lack of appetite for stocks on the mainland.
