Summary
FIFTHDELTA, a long-short hedge fund founded by former Citadel traders Niall O'Keeffe and Tio Charbaghi, has recorded year-to-date losses of 25% after a 13% fall in July, according to a report by Bloomberg. The Bloomberg report, citing unnamed sources familiar with the matter, said the fund was down by as much as 29% at one point before paring losses.

The fund was one of Europe's biggest hedge fund launches in 2021. It opened in July 2021 with $1.3bn and was closed to new money on its first day of trading in an effort to limit the amount of capital it was running. The firm currently manages around $1.5bn.

Despite the months of losses, the firm has attracted additional inflows from both founding and new investors, according to Caroline Bradley, a member of FIFTHDELTA's executive committee, as quoted by Bloomberg. "Our largest investors remain very supportive in what has been a challenging few months for the fund," she said.
