Financial Markets Authority officials raided the firm earlier this month, and both it and its director David Ross are being investigated by the Serious Fraud Office.
Bruce Tichbon represents some of the 900 investors who had invested nearly estimated $449 million with Ross Asset Management.
Mr Tichbon says says investors still have more questions than answers following a meeting with the FMA and the receiver on Wednesday.
The receiver, PriceWaterhouseCoopers, says only about $11 million has been found so far.
Receiver John Fisk told Morning Report last Friday that it's likely that investors will get only one or two cents in the dollar.
