Since closing down his fund in 1997, he began trading for his own account again in 1998, after mortgaging his house and selling his antique silver collection. This original fund is called Wimbledon Fund, the name reflecting his love of tennis. He began managing money for offshore clients in February 2002, with the Matador Fund. Niederhoffer employs proprietary computer programs that purports to predict short-term moves using multivariate time series analysis. In a five-year period beginning in 2001, Niederhoffer's fund returned 50% a year (compounded). His worst year in this period was 2004, returning 40%. In 2005, he returned 56.2% (as reported in eFinancial News). On April 6, 2006, the industry group MarHedge awarded Matador Fund Ltd. and Manchester Trading, two funds managed by Niederhoffer, the prize for best performance by a commodity trading advisor (CTA) in the two years 2004 and 2005.
