Jupiter Fund Management’s assets under management have grown by £4bn from 31 December 2014 to 31 December 2015, from £31.9bn last year to £35.7bn this year.
Last year, the fund houses assets under management grew only slightly.
Net mutual inflows were up to £549m in the three months to 31 December 2015 and cumulative net mutual fund inflows were £2.1bn in the year to 31 December 2015.
Jupiter said top selling funds included its European Growth and Dynamic Bond strategies.
Mutual fund assets under management increased across the year to more than £31bn at 31 December 2015, an increase of 13 per cent over the full year.
The fund house added overall net inflows were £496m, held back by the loss of a segregated mandate following the decision by the client to de-risk its portfolio.
Maarten Slendebroek, chief executive of Jupiter, said: “Our mutual fund franchise again delivered healthy net flows of £0.5bn this quarter, resulting in cumulative net mutual fund flows of £2.1bn for the full year.
“2015 has been another good year for Jupiter, reflecting our strategy to diversify by product, client type and geography, all supported by strong investment performance.
“Across the whole of 2015, these combined to deliver organic mutual fund flow growth of 8 per cent and to increase total AUM by 12 per cent to £35.7bn despite broadly flat markets.”
