Liontrust Asset Management saw its assets under management leap by 15 per cent in the six months to the end of September 2018, rising to £12bn.
In a trading update, the company said inflows were arriving from a broader spread of clients and into an expanding number of strategies than in previous years.
The company saw net inflows of £723m for the six months ending 30 September, with UK retail new inflows responsible for £707m of that.
John Ions, chief executive of Liontrust, said there had been notably strong client demand over the past five months for funds managed by the Global Fixed Income team.
He said: "This has resulted in David Roberts, Phil Milburn and Donald Phillips now managing nearly £300m across the Strategic Bond, High Yield Bond and Absolute Return Bond strategies."
Mr Ions said investors' appetite for sustainable investing had also continued to grow which had driven a increase in assets managed by Liontrust's sustainable investment team from £2.5bn when they joined the company in April 2017 to £3.4bn.
He added: "We believe our team’s positive and thematic investment approach will continue to drive demand."
An increase in volatility in global bond markets could auger well for Liontrust, Mr Ions said, because the company’s Global Fixed Income and Sustainable Fixed Income teams were "well positioned" to manage investors' money in this environment.
He said: "They are very experienced teams, have strong long-term track records and have flexible investment mandates, and therefore we are confident they will continue to attract inflows into their funds."
The company’s Economic Advantage range also saw inflows, despite concerns related to the UK’s imminent departure from the European Union.
