Shares in the firm shot up three per cent in the first 90 minutes of trading after its half year results showed £210m of quarterly flows into its mutual fund range and £37m of flows into its private clients business.
The company, which has a strong foothold in the retail equity fund market, also revealed it had paid down £33m of debt, leaving it with £110m left to be serviced over the next three years.
Chief executive Edward Bonham Carter said: “There’s lots of reasons to be nervous out there, but the profile of fund flows are better in general.
“That may be because UK investors hold their nerve rather better. It’s a combination of a good customer base and good fund performance.”
Headline figures for the firm were downbeat, with pre-tax profits down from £37.3m a year ago to £31.2m.
Meanwhile a four per cent drop in net management fees also pushed revenues down from £128.3m last year to £117.7m today.
BarCap analyst Daniel Garrod said Jupiter funds’ outperformance was a “differentiator which allows it to continue building assets”.
Analyst Thomas Mills from Keefe, Bruyette & Woods added: “These results confirm that, whilst concentrated, the business is best-in-class in the UK retail space.”
