Nortel

Can you imagine that at one time this stock was changing hands for $900 a share? This company was eaten up by Cisco and Juniper which are both down on the day. I would expect that these two will just get larger with one major competitor now extinct and cost of entry into this business very high since companies probably won't be able to borrow like they used to nor issue more shares as well.

Nortel had 2.66bln cash, and 4.49bln debt. But the driver was negative cash flow of -61mln. They just couldn't make a profit.
