Hedge fund RAB shares plummet as says may delist

``RAB Capital Plc (RAB.L) said its days as a listed group may be numbered after another wave of client departures, underscoring its status as one of the highest-profile hedge fund victims of the credit crisis... Shares in RAB, which has struggled to win back clients after notoriously buying into Northern Rock [NRTRK.UL] just before the UK lender's collapse, were 22 percent lower at 1034 GMT at 7.86 pence, wiping some $17 million off its market value.''
