Shares in Chinese real estate developer Dalian Wanda Commercial Properties Co traded flat in Hong Kong's biggest listing since 2010 as concerns about debt and a high valuation offset optimism over a rebound in China's property market.

Stock in the world's second-largest developer of shopping malls and office buildings was unchanged in the early morning from the initial public offering price of HK$48.00, while the benchmark Hang Seng index gained 0.1 percent.
