Hedge fund activism made a high-profile return to Europe on Tuesday when it emerged that Jana Partners and co-investor Alberta Investment Management Corporation had taken a 5% stake in Dutch postal services giant TNT – a move seen as a prelude to the sale of the group. Jana’s move, disclosed by the Dutch market regulator, marks a return to activism, with echoes of its boom-time peak in 2007 when hedge funds triggered the sale of ABN Amro to RBS.
