The Chicago firm hopes to raise $2 billion in coming months and is saying it ultimately could raise $5 billion for its new Citadel Global Macro Fund, overseen by former Moore Capital Management trader Kaveh Alamouti, according to marketing documents seen by the publication.

Insiders say turbulent markets and hedge-fund shakeups will make the $2 billion goal harder to reach, the WSJ said, citing unnamed sources. Hedge-fund investors globally are withdrawing money.

Nevertheless, Citadel hopes to benefit from the relatively strong performance of macro funds last year, one of the few strategies to make money. Citadel started building a focused macro team last year. Some money from its long-operating Kensington and Wellington hedge funds was allocated to the strategy in the summer, helping to offset losses elsewhere, according to documents.
