Prominent Chinese investment banker Bao Fan is missing, his company China Renaissance Holdings said late Thursday.
China Renaissance said it "has been unable to contact Mr. Bao Fan," according to a filing with the Hong Kong stock exchange.
The Beijing-based fund manager and investment bank is operating normally, the filing said.
Bao is the firm's controlling shareholder, as well as chairman, executive director and CEO. He did not immediately respond when contacted by CNBC about the news.
Shares of China Renaissance plunged by more than 20% in Hong Kong trading Friday.
