I don't know...
The referenced recent disclosures of material acquisitions were filings on investment firms or funds not the company itself. You hope this is a positive, but without details of the transaction(s)that caused the reporting requirement, you can't be sure (ex. general accumulation, warrant execution, debt to equity conversion, preferred to common conversion, Firm M&A, etc.)
My hopes are that the WLB news regarding stifled negotiations on the debt restructuring between companies coming out during the time of the February market correction may have set off some stop loss triggers creating a domino effect to advance this recent tumble.
Others on this chat board are concerned that the steep drop & sell off could be a sign of more to come.
The big question is do the changes in key management roles help lead the company back to profitability or create confidence in the markets to raise capital during a time that coal futures look a little better. If one or both of these do not happen in the near future, the long term sticking power of the balance sheet is questionable.
Tough call here...
My opinion only
