Ken Griffin says Citadel unwound more than 80% of risk tied to Situational Awareness portfolio
Ken Griffin said Citadel has unwound more than 80% of the portfolio’s risk through over 100 block trades worth more than $4 billion.
- On Friday, Ken Griffin confirmed Citadel unwound more than 80% of aggregate risk from the Situational Awareness portfolio purchased in late July, executing over 100 block trades totaling more than $4 billion in market value.
- Situational Awareness, a hedge fund run by Leopold Aschenbrenner, sold public stock positions after heavy losses triggered margin calls and compulsory sales, with holdings in Micron and other companies losing more than 35% of their market value.
- Griffin credited the rapid transfer to the "extraordinary cooperation of the trading and prime brokerage teams at the banks serving both firms," while Citadel's flagship Wellington fund returned 5.94% in July, its best monthly performance since 2022.
- Bolstered by the acquisition, the Wellington fund's July gains pushed Citadel's year-to-date performance to 12%, marking the flagship fund's strongest monthly return since 2022.
- Before the market downturn, Aschenbrenner's fund had grown to approximately $45 billion by early July, betting that an AI boom would drive sustained demand for chips, memory, data centers, and power infrastructure.
