British hedge fund firm Man Group said on Tuesday that its assets under management rose 19 percent in the first half of 2017, but cautioned growth is set to slow over the next six months.

Total assets under management at the end of the first half of the year were $95.9 billion, up from $80.9 billion at the end of December.

Asset growth was boosted by new investment at lower margins and the acquisition of real estate fund Aalto, which added $1.8 billion.

“The first half was unusual in both the scale of net inflows, and the level of margin compression,” said Luke Ellis, Man Group Chief Executive.

“We would expect both to moderate in the second half, particularly given the uneven nature of institutional flows.”

Man Group’s long-only funds, which aim to profit when markets rise, and its alternatives strategies took in the majority of new assets, adding $4.5 billion and $3.7 billion, respectively, over the first six months.

The only strategy to lose money was discretionary stock-picking unit GLG, from which investors pulled $900 million during the same time period, despite improved performance, with two GLG funds making double-digit returns.

Most of Man Group’s funds posted a positive performance with the exception of quantitative unit AHL, which racked up losses in three of its four funds.

Adjusted profit before tax increased by 48 percent to $145 million compared to the first six months of 2016.
