London CNN  —  The head of one of the world’s biggest hedge funds says artificial intelligence systems are unlikely to replace traders anytime soon. London-based Man Group, whose assets under management hit an all-time high of $178.2 billion during the first six months of the year, makes its money by charging investors management and performance fees. That figure climbed by 54% between 2018 and 2023, even as the firm’s average number of employees rose by just 30% — thanks in part to its use of technology.

And it’s the same with technology…I can appreciate the skill and what that tool might provide you, but you still want it in the hands of skilled people.” Publishing earnings Friday, Man Group cited robust growth in its credit business, which includes investments in assets such as private loans, corporate and government bonds. Its revenue from management and performance fees jumped nearly 45% to $733 million during the first half of 2024 compared with the same period last year. Shares in the company, which is listed on the London Stock Exchange, jumped 3% on the news, but had pared some of those gains to trade up 1.6% by 8:05 a.m. ET. In the interview with CNN, Grew said the era of rock-bottom interest rates that broadly defined the decade following the 2008 financial crisis had made way for a period of “volatility and dispersion” ushered in by the rise in inflation after the pandemic. In other words, traders navigating a volatile market can expect to make a greater range of — and possibly bigger — returns across various assets than during more stable times.
