@hawkeye10,
That only supports the likelihood of a tsunami in the stock market; the low trade volume shows the big institutions are shy about trades when the future is unknown. Most have figured out how to protect their investments; the smart ones know that some companies with good management will survive this storm. They've proven this over the many ups and downs of the market since the Great Depression.
Finally, it's my personal opinion that if we don't have trust in our economy (investments in our businesses), there is nothing more we can do but to give up. I'm not there, yet. IMHO, I still feel that the US economy is relatively strong compared to the world - including Europe.
It wasn't that long ago that many financial pundits were talking about the Euro taking over the US dollar as the universal currency.
I didn't believe it then, and I don't believe that now.
Look what happened to China. Their major investments is in US treasuries, and several years ago they started buying more Euro bonds because they felt squeamish about too much in US treasuries/securities.
Look what's happened since then to Greece, Ireland, and Portugal - with Italy next in line for bailouts. The US still looks pretty good to this observer.
