UK-listed alternatives manager RAB Capital this morning revealed assets under management doubled to $5.2bn (€4bn) last year and that it expects to buy its third hedge fund manager in the next 12 months.

The firm said its revenues had also doubled, from £56.9m (€87m) in 2005 to at least £116m, according to unaudited estimates, and that pre-tax profits increased from £25.6m to more than £50m.
