Europe's largest hedge fund manager has sought to address concerns among some investors that it is too large to continue making strong returns in markets that are shallower than they were before the financial crisis.

The managers of the BH Macro fund said in a report last week that some investors in Brevan Howard Asset Management's $16bn (€10.8bn) flagship fund were worried about the fund's future performance because it was too big. BH Macro feeds into the flagship global macro master fund, which has $16bn in assets.
