Oct. 6 (Bloomberg) — Hedge funds such as Atticus Capital LLC are betting that Archipelago Holdings Inc. and Nasdaq Stock Market Inc. will dominate the business of U.S. stock trading as markets combine.
Atticus raised its stake in Archipelago by 20 percent since June, according to a regulatory filing last week. The fund, led by Timothy Barakett, became the third-largest investor in the electronic market, being bought by the New York Stock Exchange.
Andreas Halvorsen’s Viking Global Investors LP, another hedge fund, is the eighth-largest holder of Nasdaq, which is expanding in electronic trading by buying Instinet Group Inc.
