Over the six months to 31 December 2013, assets under management fell 2.7% to $75.3bn (£47.6bn). Meanwhile net outflows stood at $2.9bn (£1.7bn).
The group reported a profit before tax of £79.5m. This is down 34% from £120.2m in the first half of the year.
The second half year nose-dive was attributed to a weaker market backdrop which impacted performance for much of the period.
“Despite the broader environment, investment performance remains strong across the group with 95% of assets outperforming their respective benchmarks over three years and it is particularly satisfying to report the strong outperformance across the equities theme,” Mark Coombs, chief executive officer, said.
He added: “The recent instability in the markets in which Ashmore invests has created attractively valued securities and the economic and political fundamentals remain positive across many of the countries that comprise the diverse emerging markets investment universe.”
