(Original) The ticker symbol is 1688.HK. It opened at HKD 30.00, a big jump from the IPO price HKD 13.50.
I have not looked at its prospectus, as I am not interested in big name IPO, nor am I an expert in B2B. Andy Yu wrote a good blog about B2B, the business Alibaba is involved in.
On the other hand, I do like the other arm of Alibaba group, the Alimama, or Ali Soft. Alimama is an online ad platform for small business. I think at some point it will challenges Baidu and Google.
Alibaba and Alimama are separate divisions of Alibaba group, the group owned and managed by big mouth Ma Yun.
