Buyback? Impossible. It would be illegal. And COWI doesn't have enough money to buy a cup of coffee, much less any of its own stock.
COWI is insolvent. They can't pay their bills - they are nothing but a pump and dump to help the toxic death spiral lenders get back the money they have been lending COWI for over a decade which remain unpaid and in default. By law, they can't buy back a single share. That isn't going to change, regardless of the stock price.
Before people start throwing money away on worthless stocks like COWI, they should take a few minutes to understand how the stock market works and the basic laws and regulations which govern public companies.
