As I have been boringly reminding everyone since TRT's near-term peak in Oct, the share price has been under continued downward pressure from shorting & impatient traders and this should be expected to continue until a significant news release breaks the trend. This is normal behaviour. If you've been profiting from running a short position during a vacuum of any real news, you'll be encouraged to retain that position and even increase your exposure during occasional bounces to discourage positive thoughts and so maintain a downward momentum. It doesn't take much selling in a thin market to achieve this and as the price drifts down you're also aided by natural selling of weaker holders. The flipside of course is that this process can be reversed instantly with news or a sudden surge of buying by bargain hunters and you'll likely take a loss closing your short, but that's just a deduction from previous profit - although it can swallow all your prior profit and then some if slow to act.
There's been no evidence of institutional selling, which they normally try to Place and not resort to quick & brutal dumps or the gradual feeding of unwanted shares.
