Watch CNBC’s full interview with Man Group CEO Robyn Grew

Robyn Grew, the CEO of the largest publicly traded hedge fund, says hedge funds are ‘more relevant than ever,’ even as the industry suffers from outflows and underperformance. For its part, Man Group, in the most-recent quarter, reversed two quarters of outflows and drove assets under management to a record $178 billion. In her first CNBC interview, marking her one year as CEO, Grew said that the need for hedge funds is even greater as interest rates remain high, despite recent cuts, because passive investing is “not as reliable as it was before.”
