What is air canada shareholders reasoning?.I don't get it. With all the positives a.c. share plummet.Is this stock continually getting shorted? It seems the downward spiral , no matter what the news just continues. Google finance is totally on another page than me when they say , how long can air Canada's upward spiral continue. Where the heck do they see this. Always negative for air Canada but they have all positives for westjet. I prefer 'marketwatch'. How low can it go, before investors wake up. This isn't blackberry.
