The FTSE 250-listed firm said its gross management and other fees rose by 26% to US$423mln in the six months to 30 June, up from US$378mln a year earlier.
Man Group's total assets under management at end June was US$113.7bn, up from US$109.1bn at the end of December, with net inflows of US$8.3bn offset by performance losses and the impact of a stronger US dollar.
The company’s adjusted first-half pre-tax profit was up 5% year-on-year to US$153mln, constrained by investment losses of US$1.7bn and negative currency movements of US$2bn as the US dollar strengthened against most major currencies.
It said trade tensions between the US and China weighed on sentiment in the period and a stronger dollar and higher U.S. interest rates contributed to pressure on emerging markets.
Man Group’s chief executive officer Luke Ellis said: "Given the difficult market backdrop and weaker performance in the first half, funds under management and adjusted profit growth were more limited."
Interim dividend hiked
The hedge fund is paying an interim dividend of 6.4 US cents, up from a 5.0 US cents pay-out at the same stage 2017.
In early afternoon trading, Man Group shares were 5.6% higher at 183.15p.
In a note to clients, analysts at Numis Securities said: “Man looks about fairly valued in our view, albeit we continue to believe that there are cleaner, less volatile companies in the sector with greater long-term shareholder return potential.”
They repeated a ‘hold’ rating and 185p target price on the stock.
