On August 30 Petro Canada (pca on TSX) closed at about $95.00.
Today it started trading at about $47.00

I cannot figure out that the hell happened. I don't see any stock splits and nothing major in the news regarding petro canada. Can anyone tell me what happened. I would think a major Canadian oil company dropping $50.00 in one night would be fairly significant. Their own website investor information doesn't say anything about the drop as well.

What am I missing here??

Thanks!

   

maybe coz of the ongoing gas crisis

   

so as the price of the stocks drop, the execs. raise the prices so they'll have even mor ebillions to buy even more stocks for cheaper.
