An unnamed retail investor has called on other investors to sue the Securities and Futures Commission for compensation to cover his losses arising from the commission's share suspension policy. The investor advertised in a Chinese newspaper on Tuesday saying he had bought shares in a listed company last July - a company which was then suspended by the SFC for four months. When the share resumed trading, the price dropped 70 per cent. The investor accused the SFC of abusing its power. He said he would sue the watchdog and asked other investors to contact him via his appointed lawyer.
