In the first half of 2026, Ken Griffin's Citadel reported positive returns across its hedge fund strategies, with the tactical trading fund leading the way with a 14.3% increase through June. This fund, which integrates discretionary equity investing with quantitative methods, managed to avoid a recent downturn in quantitative investing that affected many systematic strategies.
Citadel's equities fund also performed well, returning 11.2%, while its flagship Wellington fund gained 5.7%. The firm's global fixed income fund saw a modest rise of 1.7% in June. These gains occurred during a tumultuous period for financial markets, characterized by fluctuations in oil prices, concerns over artificial intelligence investments, and changing Federal Reserve policy expectations.
The S&P 500 index rose 9.6% in the same timeframe, reflecting a broader market recovery after earlier declines. As of June 1, Citadel managed approximately $69 billion in assets, indicating its substantial presence in the hedge fund sector
