(Wall Street Journal) London-based hedge fund Roxbury Asset Management, headed by alumni from high profile funds The Children’s Investment Fund and ECM, has raised $47 million for its launch in a tricky environment for start-ups. Based on London’s Savile Row, next to the building where the Beatles performed their famous 1969 rooftop concert, Roxbury will bet on events such as refinancings, restructurings and earnings announcements in credit and equity markets.
