Ken Griffin’s Citadel posted positive returns across its various hedge fund strategies in the first half of 2026, driven by double-digit gains in tactical trading and equity funds.

Citadel’s tactical trading funds also survived the quantitative shakeout in late June. Quantitative investing relies on mathematical models, statistical analysis, machine learning, and algorithms to identify investment opportunities, construct portfolios, and manage risk.

Citadel’s equity fund returned 11.2% in the first half after gaining 3.5% in June, while the company’s largest flagship multistrategy Wellington fund rose 5.7% through the end of June after gaining 1.8% in June, the people said.
The firm’s global bond fund rose 1.7% in June, little changed for the year.
Citadel’s gains came during a volatile first half of the year in financial markets. of S&P500 Up 9.6% through June, the benchmark recovered to new highs after five consecutive weeks of declines in February and March.

Citadel declined to comment.
