@cicerone imposter,
exceptions that prove the rule, though I think all that you list do have a good stash of cash. The thing we don't know though is were was it? They may have lost a bunch of it already, depending one where it was parked. A lot of money was placed in safe places that proved not to be very safe.
Ya, i know the bought their own stock, and drove up the price....and later they issued new stock to replace it, so the market cap went up. If the true value of the stock was $30 but the company was buying it, the price may have gone to $35 because of the buyinf demand imposed by the company itself, you know, the laws of supply and demand. They then would issue new stock and get $35 for it, and big chunk of that would go to the wall street furm handling the issue as well as all of their friends. Then repeat, maybe get the stock up to $40.
The company is still worth only $30 a share, and now with the crash maybe $20.
