Magnus Peterson, boss of failed London hedge fund Weavering Capital, pleaded not guilty to all 16 charges of fraud, false accounting and forgery in his trial at a London court on 14 October.
Peterson's purposeful "dishonesty" resulted in the collapse of his $600m (£377m, €474,) hedge fund, prosecutors told a London court on 13 October, the trial's opening day, reports said.
The high-profile trial is expected to last 12 weeks.
Weavering Capital's collapse is the subject of an ongoing probe by the UK's Serious Fraud Office (SFO).
The SFO has accused Peterson, a Swedish-born hedge fund manager, of fraudulent trading, fraud by misrepresentation, forgery, abuse of position, false representation, furnishing false information and obtaining a money transfer by deception between 2003 and 2009.
In September, liquidators of the collapsed hedge fund sold a house belonging to Peterson for about £1m, in a bid to recover the $450m in damages that they were awarded in a civil case two years ago.
The SFO re-opened its case against the firm in July 2012, after Weavering was ordered by Britain's High Court to pay the $450m following its 2009 collapse, which followed the banking crisis at the end of 2008.
