Maybe I have gone insane - but I just bought 1m shares at £3100.

I think the market may have overcooked the profits warning and the share price could bounce back. I did write to the company sec about the dissapointment in the share price over the 4 years I have held them - and she did reply with a well worded thoughtful reply which offered some light at the end of the tunnel. The pension gap is closing (slowly) and I see the company as being investable in the near future. Maybe it's not so silly to buy in now?
