Brewin Dolphin Holdings was in the top spot after appointing former Morgan Stanley boss David Nicol as Chief Executive Officer after Jamie Matheson resigns as Executive Chairman. Matheson, who is stepping down after eight years, will work with Nicol and the management team to ensure a smooth transition to the new leadership, the group said. Premier Farnell was higher despite posting a three per cent decline in fourth quarter sales. Adjusted pre-tax profit fell 7.9% to £18.7m, while adjusted earnings per share declined 10% to 3.6p. It also reported that 2013 had got off to a positive start. Vesuvius fell after it said its trading in 2012 was hurt by a weaker steel and foundry market in the second half. The group, which makes ceramic moulds and linings for steelmakers and foundries, saw revenues fall by 8.1% year-on-year to £1.5m and trading profit plunge 27.5% to £133m.
