Indalo,
You are obviously not much of a pro and a newcomer to the game.
A lot of us got out at 80+ and back in just over 70. Your short earlier in the week was very lucky to come off (just a few to many stop losses hit) but as I said at the time I was and am grateful for the extra bargain price stock.
I never short. Only buy underpriced stock and sell at a profit.
So far this year have done well out of echo, griffin, vernalis, greenich (buying again shortly), and a few others that I prefer not to name now as I am not a tipper and work for myself ( although most of the above will probably go up more yet).
I take my 20%+ and am happy.
I will sell these at 90p+ within 4 weeks, probably sooner.
Be warned, this will happen. Short at your peril. I will buy everything you put out under 68.
