I have lost probably 15% of my savings with this company..because I'm an idiot. I kept trying to catch the falling knife, believing a turnaround was coming.
I feel 10c or lower is coming, but I'm scared that if I sell it'll go up and I'll have made another brilliant [not] decision. But what I really want to know is, what should we be looking out for as a warning sign that the wrighting is not only on the wall, but now it's underlined with exclamation marks. I.e. the rats are about to suck it dry
