The dollar rose after the Nov. 8 U.S. presidential election on expectations that President-elect Donald Trump's plan to boost fiscal stimulus would benefit the currency. A faster than expected pace of rate hikes from the Federal Reserve next year also contributed.

Combined assets under management declined $2.4 billion during the three months to the end of December, with negative market moves accounting for $1.7 billion and net client withdrawals $700 million.

That took total assets to $52.2 billion from $54.6 billion at the end of September.

Despite the tough quarter, emerging markets had chalked up a strong 2016 calendar year, adding 5 percent to Ashmore's assets, said, Ashmore Chief Executive Mark Coombs, and asset prices had strengthened in December and into the new year.

"The combination of attractive absolute and relative returns, accelerating GDP growth, and low allocations all support the expectation of further strong performance in 2017 and a return to the improving flow trend seen for most of 2016," he said in a statement.
