Sushil Wadhwani has closed his flagship global macro hedge fund to concentrate on computer-driven trading after the former Bank of England monetary policy committee member decided he did not have enough time to do both. Wadhwani Asset Management’s Keynes fund raised more than $1bn after it was launched in 2003, making it one of the year’s biggest new European hedge funds. But, after a strong start, performance flagged in 2005 and it made a small loss for investors last year. Since launch its annualised return was just under 6 per cent.
