Odaily Planet Daily reports that billionaire Ken Griffin’s hedge fund Castle Investment is facing its worst annual return since 2018, following losses in its natural gas bets, which were a major source of profit for Castle Investment. According to an informed source, as of December 18, the flagship fund’s return was 9.3%. The fund profited from stocks, fixed income, credit, and quantitative strategies, and even achieved small gains in commodities (including natural gas), after experiencing losses earlier in the year. Even so, with less than two weeks remaining in the year, 2023 may become the sixth year since Castle Investment’s founding in 1990 to have a return below 10%, highlighting the company’s recent reliance on commodity trading, which has driven its high returns in recent years.
