RE: Could care less about yesterday....Don't beat yourself up too much over CS. The base metal sector is out of favour right now, since it's deemed to be economically sensitive and investors are not thrilled with the current economic climate - there goes the base metal mining stocks in the tank.
If you have the patience, base metal will comeback. When? None of us know. I also own QUX and TCK.B, same story there. So it's a matter of voting with your feet. In fact I did something yesterday. I sold some QUX and bought more CS. Just because I think CS can likely bounces back sooner than QUX. I'm getting bored so I felt compelled to do something.
This may be a "prison laudry day" type of swap. In case you don't know, here's the story. "The good news is today's laundry day in the prison, the bad news is Bob you swap your cloths with Joe, and Joe you swap your cloths with Bob......." .
Hey CS looks cleaner than QUX yesterday, so I made that swap.
