The growth pushed retail assets under management to more than £7.3bn between April and June this year, driven in large part by its completed acquisition of Alliance Trust.
Total AUM at the firm stood at £9.25bn by the end of June, with £945m held for institutional clients and a further £604m in multi-asset strategies.
Despite the solid growth, total net flows amounted to £22m owing to a large £149m redemption from one institutional client.
Chief executive John Ions took the opportunity to give his view on the recently published FCA Asset Management Market Study and said: “We welcome the FCA Asset Management Market Study given that the low savings ratio is a problem for the country.
“As active fund managers, there is a key role for us to play in helping investors meet their financial requirements. The moves to improve transparency, communication and value are steps in the right direction.
“There is a significant role for the asset management industry to play in alleviating the savings problem. I believe Liontrust is in a strong position to achieve this with our focus on active fund management, investment processes along with client service and communications.”
Liontrust completed its acquisition of Alliance Trust in early April, bringing 11 new sustainable investment funds under the Liontrust brand.
It follows a year of rapid growth for the firm which held AUM of £4.8bn at the end of Q1 2016.
