The firm witnessed net inflows of £189 in the six months to the end of September, three times the sales of £59m seen in the equivalent period last year.
Revenues also increased by 59% over the six-month period versus the same period last year.
John Ions, chief executive of the firm, said: “Liontrust continued to make good progress in the first six months of our financial year to 30 September 2012. Fund performance and distribution capability are key to this trend continuing.
“Since the funds were launched or the current fund managers were appointed, all bar one of our nine actively managed unit trust funds have outperformed their benchmark and the average fund performance in their respective sectors.
“While there has been much focus recently on the cost of fund management, we continued to believe investors will be prepared to pay for active managers who can deliver outperformance and in our case this has been achieved across our fund management teams.”
The acquisition of Walker Crips Asset Managers, which cost £4.9m led to a pre-tax loss from continuing operations of £4m, but adjusted pre-tax profit was £900,000 compared to £22,000 in 2011.
An Analyst note from N+1 Singer gave Liontrust an intrinsic valuation of 142p (its current share price is 103p) based on a peer group valuation multiple and said it remains a strong buyer on a long-term view.
