Global Hedge Funds Suffer Record October Losses Amid Market Turmoil
Major global hedge funds, including Greg Coffey's Kirkoswald Capital and Steve Mandel's Lone Pine, suffered sharp losses in October amid severe market volatility, triggering widespread job cuts and a harsh reality check across the financial sector.
Greg Coffey, famously dubbed the Wizard of Oz for his exceptional capital markets acumen, could not escape the recent global market turmoil. According to Business Insider, Kirkoswald Capital, the hedge fund founded by the Australian investor in 2018, suffered a staggering loss of over 6% in October, marking the worst month in its history.
To put this unprecedented drop into perspective, Coffey boasts an enviable track record. Since its inception, the fund has generated an average net annual return of approximately 17%, and in 2025 alone, it posted a 21% gain. This consistent success propelled its assets under management to roughly $20 billion. Despite the October setback, Coffey maintains a positive year-to-date return exceeding 16%, yet he is hardly alone in facing severe market headwinds.
Steve Mandel's prominent hedge fund, Lone Pine, offers an even more dramatic cautionary tale. Bloomberg reports that the fund had surged by 44% earlier this year, only to see those gains entirely erased alongside an additional 9% loss in October. By the end of the month, its year-to-date performance had plunged to a negative 7%, placing it among the weakest performers in its peer group.
Broad Market Impact and Job Losses
The volatility extends far beyond a few high-profile managers. Data compiled by Goldman Sachs indicates that tech-focused hedge funds shed more than 4% in a single day on Thursday. Their year-to-date returns have flattened to near zero, a sharp reversal from their peak of 24% in June. Meanwhile, JPMorgan estimates that global hedge funds sustained an average loss of about 3% in October.
This financial squeeze is rapidly altering the labor market within the hedge fund industry, which until recently engaged in fierce bidding wars for top investment talent. According to Business Insider, numerous funds are already parting ways with senior managers and key personnel.
A Harsh Reality Check
In an industry where roughly 20% of portfolio managers typically turn over annually across multi-strategy funds, tolerance for losses remains exceptionally thin. As markets grow increasingly volatile and profits evaporate, pressure on investment managers is mounting.
Elliott Management founder Paul Singer warned earlier this year that the aggressive war for talent had become overextended during the prolonged bull market. "The next significant bear market could lead to a comprehensive rethinking of how investors define excellence," Singer wrote in an investor letter.
Despite the grim landscape, certain funds successfully navigated the turbulence and even turned a profit. However, for managers caught on the wrong side of the market, the current climate has transformed into a high-stakes survival test.
"Now it is strictly a game for the big players," a veteran portfolio manager told Business Insider, noting that he managed to keep his own job—at least for now.
