Hedge fund assets had risen to more than $2 trillion (€1.5 trillion) by the end of October and have grown by more than a half in the last 12 months, according to a survey of administrators.

The survey of 57 fund administrators said hedge fund assets had grown 53% from $1.3 trillion at the end of October 2005 to just over $2 trillion a year later, according to HFM Week, a hedge fund industry magazine that commissioned the study.
