Father's Day may have taken on new meaning this year for Lord Jacob Rothschild and his son Nathaniel, who co-chairs Atticus Capital. In June, it became known that Lord Rothschild's investment house RIT Capital had pulled its £36.5 million stake out of Atticus, the troubled event-driven hedge fund managed by Tim Barakett. Atticus performed poorly last year and at one point this year had moved most of its roughly $6 billion in assets into cash. In explaining the decision, RIT argued that its investment in Atticus had "run its course." But familial ties are not completely frayed. Nathaniel remains a director for RIT.
