BlueCrest Capital Management's BlueTrend fund, one of the world's biggest computer-driven hedge funds, has suffered one of its worst ever peak-to-trough losses over the past six weeks, according to a report by Reuters.

A listed feeder fund that channels capital into the $16bn BlueTrend fund lost 16.9 percent between May 17 and June 28, regulatory filings show.

The feeder fund closely replicates the performance of BlueTrend's flagship fund. The feeder fund's performance equates to a loss of roughly $2.7bn in the main fund, which was launched in 2004 and has never had a losing calendar year.
