To start, I am long ECIG.
I don't have answer to your questions, but my feelings tell me conversions indeed have occurred yesterday and today. The sharp drop has occurred early morning and has ceased. To me it cant be sorting only, rather conversion. I may be wrong though.
Why would anybody short this? Recall, only 15% of the debt has converted so far. 85% is being restructured. So if the company decides to pay with shares, then we will go much much lower.
Long and strong ECIG
