Looking at the chart on this one, my surprise is that it's been a civilised fall. Between here and the key supports at 294 and 212 I would expect to see more volatility because the gains at the end of last year were so rapid. Small volume so far today.
But I have known cawkwell predict these profit warnings before and get them spot on, obviously party to you know what but the fsa never seem to be able to collar him.
