Liontrust Asset Management enjoyed net inflows of £190m in the final quarter of 2016, bringing its assets under management to £6bn at the end of the year.
In a trading update for the period from October 1 to December 31 2016, Liontrust noted that the quarter's performance had brought net inflows for the financial year to the end of 2016 to £282m.
John Ions, the firm's chief executive, described the Q4 performance as "strong" but warned 2017 could be another difficult year for asset managers.
"The asset management industry is facing a number of significant challenges and opportunities as we enter 2017, including through regulatory, political and economic changes," he said.
"We are well placed to deal with the challenges and to exploit the opportunities during this unprecedented environment given the ongoing development of the business.
“This includes the investment in our internal infrastructure, including a new dealing system, fully integrating our sales and marketing systems, notably through our CRM, and Ian Chimes joining in February as head of global distribution."
Last year it emerged that Mr Chimes, former sales head at Miton, would be joining Liontrust.
The latest move by the firm - a planned acquisition of Alliance Trust Investments announced late last year - is expected to add £2.3bn of assets under management.
