It used to be that one could assume the Market would thru supply/demand and investor knowledge properly price shares in various sectors of the economy. Probably it does a pretty good job during a stable period. Where it really falls down is during short periods of time where everything is out of wack because of panic and serious decoupling with value.
Look at the Yo Yo action on US Market this morning. There are sellers out there, motivated sellers who need money or are panicing. Buyers? well not many with cash they are willing to invest since they want to wait for the eventual turn around.
All we can do know is NOT SELL and wait for things to settle down and that includes the price of Metals as that's been subject to same conditions. Gold this morning acting really weird and C$ down another 2 cents against US which is way out of line with basic economic strenght of Canada.
