At the time of writing, the stock market valuation of GM is $11.89 billion. Ninety minutes ago it was $12.08 BN. So the value of America's leading car manufacturer has dropped by $190 million since I logged on. Let's say 6,000 Cadillacs! GM's value is down around 10% so far this week.
I note that the Royal Bank of Scotland is worth $91 billion tonight. Somehow, I think that things are out of balance.
