The second quarter results, ending 31 March, showed the firm had increased funds against last year from £29.7bn to 34.4bn an increase of 8.7% over the quarter and 15.7% over the year.
Inflows were down on the previous year’s results from £1.5bn to 1.4bn.
Over the quarter the FTSE All Share Index rose by 8.3% and the MSCI World Index rose by 9.4%.
Ian Taylor, chief executive, said: “I am pleased to report that funds under direction have shown strong growth, reflecting positive net flow growth in the quarter and the upward movements in world equity markets.
“Political and economic uncertainties have not gone away, however, and still give rise to unhelpful background noise.”
The company says it expects to announce half year results on 17 May.
