Henderson China Holdings' initial public offering was 2.4 times oversubscribed, topping analysts' expectations.
The amount slated for the public had been set at 8.31 million shares but the firm decided to place a further 3.49 million shares to satisfy the demand.
Henderson Land is spinning off its China property assets into the new company, raising $1.5 billion by issuing new shares to the public and to institutional investors.
The extra shares being sold to retail investors will be taken from the 59.3 million shares that were to be available for institutional investors, bringing that number down to 55.81 million.
Analysts had expected the public offering to do poorly as recently as two weeks ago after the Hong Kong market fell more than 7 per cent in one day.
Ten days ago, the firm priced the new shares at $21.50 each at the low end of their projected range, representing a 25 per cent discount to net asset value.
