Jupiter cited significant flows into its fixed income, absolute return, multi asset and global emerging market strategies, in its trading update on the three months to 31 March.
There were also positive contributions from its recently opened offices in Italy and Spain which helped the growth in Europe, Jupiter said.
The combined impact of these inflows with investment performance and currency effects led to mutual fund asset under management increasing to £38bn as at 31 March 2017, a 7.9% jump over the quarter.
Maarten Slendebroek, chief executive, said: “We are pleased to report a strong start to 2017, driven by our mutual fund franchise which saw net inflows of £1.4bn. The continued strategy to diversify our business by product, client type and geography and delivery of strong investment performance after fees across a broad range of strategies has resulted in good inflows both internationally and within the UK.”
