The world’s largest listed hedge fund Man Group reversed outflows from its most lucrative trading division in the first half of the year, sending its shares up as much as 7 per cent.

The FTSE 250 group reported $2.3bn of quarterly net inflows into its absolute return unit, reversing several quarters of outflows after its most profitable hedge fund strategies misfired in a volatile 2025, tanking profits and its share price. Performance has since improved, lifting pre‑tax profits for the first six months to $264mn from $77mn a year earlier.

Under chief executive Robyn Grew, Man has diversified into long‑only investing and private credit. Assets under management hit a record $254bn at the end of June, with the long‑only division pulling in $6.8bn and positive returns adding $16.7bn. However, margins on management fees fell 7 per cent as the mix shifts toward lower‑fee long‑only strategies.

The firm is expanding its multi‑strategy fund Man 1783, hiring around six trading teams to compete with US giants Millennium and Citadel. The fund, managing the bulk of the $3.8bn multi‑strategy segment, was up 7.9 % in the first half.
