Technology Intern

Citadel is seeking court orders to compel two senior Marshall Wace executives to provide communications regarding the recruitment of Dan Shatz, a former Citadel credit portfolio manager. Shatz joined Marshall Wace as global head of credit in late 2024. Citadel alleges that Marshall Wace partner Anthony Clarke and co-portfolio manager Alan Hofmeyr were heavily involved in recruiting Shatz and met him in London during his noncompete period. The firm claims Marshall Wace has produced limited communications since a June court order. The dispute stems from an arbitration battle between Shatz and Citadel, where he worked until summer 2023. Shatz claims he is owed a "significant eight-figure" amount after raising internal concerns about potential securities violations. Citadel alleges Shatz violated his noncompete agreement. Marshall Wace declined to comment.

Marshall Wace joins hedge fund peers in planning Japan office. U.K. hedge fund Marshall Wace plans to open a small Tokyo office next year with investment staff, joining peers expanding their presence in Japan, people familiar with the matter said. SHARE/SAVE Aug 28, 2026 Marshall Wace, the $90 billion U.K. money manager, plans to open a Japan office next year, joining hedge fund peers putting boots on the ground, people with knowledge of the matter have said. The Tokyo office will initially be small and host investment staff, one of the people said, asking not to be identified discussing private information. Pending regulatory approval, it may open in the second half of 2027, he added. A spokesman for the London-based firm declined to comment. Marshall Wace has long traded in Asia, with Japan being a key market. It opened a Hong Kong office in 2006, bringing to the region its pioneering systematic TOPS market-neutral strategy that farms ideas from equity salespeople. It still runs a Japan-focused strategy. By late October last year, more than 100 of its roughly 750 employees were based in Asia, investing with a variety of regional and global strategies. All of its Japan-focused investment staff, including Partner Daisuke Iwasaki, are currently based in Hong Kong. The firm also maintains offices in Shanghai and Singapore, according to its website. Global hedge funds have been looking for ways to boost their Japan presence and investments, as corporate governance improvements and the return of inflation bolster equity and macro trading opportunities in the market. Brevan Howard Asset Management is also opening a Tokyo office this year, people with knowledge of the matter said in April. Peers including Polymer Capital Management, Millennium Management and Point72 Asset Management have built a sizeable presence in Tokyo. Yet many experienced Japan investment professionals have historically been based elsewhere, such as Singapore and Hong Kong, for reasons including taxes. Executives of various hedge fund firms have expressed dismay over the difficulty to recruit such personnel, either based in Japan or elsewhere, with cultural and language issues exacerbating the supply-demand imbalance as global investors renew interest in the country. Tokyo's ambition to attract more asset managers is now facing additional headwinds, as both Hong Kong and Singapore have proposed tax benefits as incentives to lure them.

Morning Coffee: Intense times at the hedge fund with employee pictures on the wall. Another reason to work for Jane Street in Hong Kong. 44 minutes ago As the wisdom of motivational posters might have it, the culture of a financial institution is a bit like a teabag. You never know how strong it really is until it's in hot water. When everything is going well, lots of companies are keen to about their unique collaborative and collegiate environment. It's easy to get along when everyone's making money. But more troubled times often make the fault lines extremely obvious. And it seems that hedge fund Marshall Wace, particularly in its credit team, might currently be going through those kinds of times when the flavour seeps out. Marshall Wace has always tried to have a slightly different culture from the typical "pod shop". More collegiate, less aggressive, less... American? Paul Marshall, the co-founder, has pointed to its unusually high average employment duration and culture of cooperation and teamwork rather than eating what you kill and quickly cutting underperformers. His concern with creating the right atmosphere goes right down to taking a personal interest in the interior design of global offices, including portraits on the walls of valued employees in the style of a British pub celebrating its regulars. The trouble is that MW has historically been dominated by its market leading long/short equities franchise, and so when it wanted to build up other asset classes and strategies, that meant hiring people from outside. And new hires often come with their own culture and habits; it's one of the best-known problems in the industry that it's difficult to maintain your culture during a period of rapid growth. Adding to the problems, when MW hired Dan Schatz from Citadel to be the head of credit, Citadel got very angry and lawyered up. Lawsuits are, famously, a massive sink for management time and effort that could be better spent elsewhere; whatever your problems are, a bit of litigation will always make them worse. Just at the time when the credit team needed to be concentrating on developing a strong culture and building relationships, they had this unwelcome distraction. And Murphy's Law dictates that just when it would be really helpful to have a good run of luck in the market, the opposite tends to happen. Performance figures aren't separately disclosed for the main credit strategies, but it might be assumed from the Alpha Plus fund to which they contribute that things haven't been stellar. The end result seems to have been a number of departures from the credit unit over the last couple of years. Of course, these aren't unique issues for Marshall Wace; everyone in finance will go through some periods of adversity, and managing the teething troubles of rapid growth is the whole business of multistrategy investing. It might even be argued that tough times are what build a culture, as well as challenging it. When things stabilise at Marshall Wace, everyone on the credit desk will at least know how their colleagues react when the chips are down. That's actually quite useful. Marshall Wace declined to comment. Elsewhere, some very good news for asset managers in Hong Kong. It seems that they may also benefit from a planned change to the tax law which would effectively replicate the "carried interest loophole" beloved of private equity fund managers. The local tax authorities have made it clear that "The scope of the proposed enhanced tax concessions for funds and carried interest is not confined to particular types of funds or asset managers. Rather, eligibility is dependent on whether the relevant conditions and requirements are met". In plain English, that means that employees will benefit from it as long as they are getting a contractual share of the fund's profits, rather than a discretionary bonus. Which means that there might be some quite difficult decisions to make. Lots of firms, including some very big hedge funds, try to incorporate some element of discretionary payment into their employees' compensation, in order to encourage things like teamwork, management development and good compliance habits. But if this makes a big tax difference, the employees will be very resistant. Firms like Jane Street and Citadel are already likely to be on the right side of that line, but many other asset managers and family offices might end up deciding that although they don't like formula-driven compensation, they can't afford not to give it. Meanwhile... Driss Haj Khalifa, formerly head of euro swaps at Bank of America in Paris, has gone to Susquehanna in London. Lots of sell-side traders seem to have made this move to macro and multistrategy hedge funds in the last year.
