Another Ponzi scheme

Paul Greenwood and Stephan Walsh, principals of WG Trading Investors, were arrested by Federal Bureau of Investigation agents in February on conspiracy, securities fraud and wire fraud. The FBI alleges that Greenwood and Walsh misappropriated a majority of the more than $668 million invested in WG Trading Investors. The National Futures Association had suspended Greenwood and Walsh's membership earlier in the month for failure to produce records related to their commodity pool. The NFA audit was cited by the FBI in its release.
