BlueCrest Capital Management's flagship fund returned less than 2% in the first half, the firm said.
AllBlue rose 1.99% during the first six months of the year, thanks primarily to its investment in BlueCrest's International Fund, which rose 2.64% in the first half.
"Following a satisfactory year in 2010, the company has continued to deliver positive financial performance during the first six months of 2011 despite challenging market conditions," Chairman Richard Crowder said. "With an uncertain backdrop trading strategies have faced a challenging environment where markets have been driven by political factors, often resulting in severe dislocations. During this time, BlueCrest has continued to focus on limiting downside risk and preserving investor capital, whilst taking advantage of trading opportunities that have presented themselves."
Other BlueCrest funds were also in the black for the first half. BlueMatrix was up 3.32%, Multi-Strategy Credit 2.74% and BlueTrend 1.88%.
