Weiye Holdings (HKG:1570) flagged a high concentration of shareholding in the firm's shares following a request from the Hong Kong Stock Exchange, according to a filing with the city's bourse Tuesday.

The residential and commercial property developer's shares fell nearly 2% in late morning trade Wednesday.

According to the notice, 20 shareholders collectively controlled 83.50% of the company's issued share capital, while another 13.12% of shares were registered under HKSCC Nominees' name, leaving only 3.38% of the issued shares in the hands of other shareholders.

This meant that the shares may not have a genuine market and prices could fluctuate "substantially" even with a small number of shares traded, the firm said.
