depends on how many customers the original company had, how many of them keep checking their accounts, and if the new buyer could start a service that is exactly the same soon enough. i have paid a premium for a domain name so that i can claim that company xyz has aquired competitorxyz.com. Most people will assume that you aquired the entire company, when all you bought was the domain.
That being said the price would drop sigificantly the longer you wait, since more and more people would realize the company is belly up.
