"The numbers are mind-boggling: 15 years ago, hedge funds managed less than $40 billion. Today, the figure is approaching $1 trillion. By contrast, assets in mutual funds grew at an impressive but much slower rate, to $8.1 trillion from $1 trillion, during the same period. The number of hedge fund firms has also grown - to 3,307 last year, up 74 percent from 1,903 in 1999. During the same period, the number of funds created - a manager can start more than one fund at a time - has surged 209 percent, with 1,406 funds introduced in 2004, according to Hedge Fund Research, based in Chicago."
