If you have held for a fair while why would you sell now when the management have identified what needs to change. There is no way to predict where the bottom will be but even if it does fall further the upside potential is far greater if and this may be a big if they can get costs under control. M B has moved pretty quickly so far scapping the Hawkie contract and scaling down R and D expenditure. I'm positive he will have the whole business under the microscope so the next figures we see will shed a lot of light on whats been going on,good things I'm hoping.
