And what do they have in common with RPTN? Nothing except they were insolvent.....short term (RPTN's insolvency is not a short term problem)
Perhaps a better question would be, what do they have in common with each other that they don't with RPTN? They were able to reorganize and resolve their problems. They were still viable. RPTN cannot and is not. At least, there is nothing to suggest they can or could be. They have NO ASSETS, NO EMPLOYEES, NO IP so NO PRODUCT and they still have MAJOR LIABILITIES......
Or are you advocating investing in dying companies regardless of circumstances on the off chance? Seems like a silly way to lose money to me.
If that is not what you are suggesting, please explain to us your method of picking which companies you put your money into. Other than reading an article about companies that have come back from the grave, so to speak.
