Northern Rock kicks off with its results tomorrow and the shares defied the optimistic urgings of Goldman Sachs, which has set a fair-value price of 710p, by declining 21p to 671p. Abbey National slipped back 26p to 1050p, Royal Bank of Scotland fell 47p to 1793p and Barclays was off 61p at 2241p. With banks representing 20% of the Footsie, the rest of the market goes where they go. A record £30bn worth of earnings could be unequally shared over the next three weeks.
