This certificate is called CDR. Investors buy CDRs, which is equivalent to buying shares of these companies.
The so-called strategic placement fund (unicorn fund) we heard recently serves for these overseas listed companies to return to A shares, mainly by investing the funds raised from retail investors in CDRs.
I sorted out the flow of funds: retail investors → unicorn funds →CDR→ domestic banks → overseas (including Hong Kong) listed companies.
In other words, in fact, the mode of CDR is to let these overseas listed companies return to A shares, and the overseas listed companies in China participating in CDR this time are all Internet giants: Xiaomi, Tencent, Alibaba, JD.COM, Baidu and Netease.
