Jupiter Fund Management has seen net inflows of £1.3bn in the past quarter.
Its assets under management ended the three months to 30 September at £48.4bn, which is a year-to-date increase of 19 per cent
Maarten Slendebroek, chief executive of Jupiter, said: "We are pleased to report another quarter of healthy flows following on from a strong first half.
"Total net inflows were £1.3bn, including £1.2bn of net inflows into our mutual funds across a number of different investment strategies.
"The business momentum from our pursuit of business diversification allied with positive investment performance after fees has driven a 3 per cent increase in AUM over the quarter and a 19 per cent increase since the beginning of the year."
According to the results, net mutual fund inflows were £1.2bn during the third quarter, with significant inflows into its Fixed Income strategy as well as "meaningful" inflows into its European Growth, UK Value, Absolute Return and Global Emerging Markets strategies.
This was partially offset by outflows in its Fund of Funds strategy.
Geographically, it saw net inflows across all regions, with Europe and the UK being the highest contributors.
The news comes after the company launched the Jupiter Global Emerging Markets Short Duration Bond fund in September, which developed its newly-established emerging market debt offering following the launch of the Jupiter Global Emerging Markets Corporate Bond fund in March.
This fund was launched for Alejandro Arevalo, who Jupiter hired from Pioneer Investments last year.
Mr Slendebroek said Jupiter now aims to build on this momentum.
He said: "We believe that diversification and investment in maintaining our scalable operating model, supported by a strong and sustainable balance sheet, provides resilience to our business.
"This approach leaves us well-placed to deliver asset growth for our clients and value for our shareholders."
