Despite reducing its workforce by 4% earlier this year, mid-sized multi-strategy hedge fund Walleye Capital is still making new hires, including Rupert Graham, formerly head of options at WorldQuant in Switzerland, who has joined as a systematic volatility portfolio manager, according to a report by eFinancial Careers.

Graham, who will be based in Zug, Switzerland, most recently served as head of European options at Citadel Securities.

Graham’s appointment is part of a push by Walleye to expand its computer-driven trading in fixed income products under the leadership of Arnaud de Bevy, who joined from Brevan Howard in January. Bloomberg recently reported that Walleye achieved a 7.2% return in the first half of 2024.

Other recent additions include: Jonathan Gordon, who joined as a portfolio manager specialising in merger arbitrage and relative value from Millennium in London in June; and Brad Lloyd, who joined as a quant portfolio manager from Capstone in May.
