Premier Asset Management has seen its assets under management increase by 17 per cent to £6.8bn at the end of June 2018.
The company saw total net inflows of £202m in the three months ending in June, meaning Premier has seen 21 successive quarters of positive net inflows.
Total net inflows for the rolling twelve months to 30 June 2018 were £819m.
Mike O'Shea, chief executive of Premier, said: "Net inflows of £202m represent our twenty-first successive quarter of positive net inflows, AUM increased to a record high, and fund performance remains strong.
"These results show that Premier is well positioned in terms of our product range, performance and distribution capability."
He added: "Against a background for investment firms and our clients of economic and political uncertainty, combined with the very fast pace of technological change, we believe our focus on relevant, actively managed investment products, including our multi-asset, equity and absolute return funds, combined with our focus on client service, means we remain well positioned for the future."
Premier said in March it will be launching PremierConnect, a digital service for financial advisers, which will allow them to invest clients directly in Premier funds, offer client specific portfolio reporting, and enable payment to advisers.
