Listed hedge fund Man Group was the biggest riser in early trading, despite reporting a 40% drop in profits over the past nine months.
However, the firm was buoyed by a slowdown in outflows more recently.
Peter Clarke, chief executive of Man, says assets under management have been buoyed by performance, particularly by GLG.
He adds: “Investor sentiment has improved compared to the last quarter of 2011 and lower redemptions have driven a significant reduction in the rate of net outflows.
“But sentiment remains fragile and it is likely to take a longer period of stability in markets and continued performance before this translates into increased sales and net inflows.”
