Can someone explain this to me?I'm a shareholder, and quite happy with what the price did today. But I don't really understand WHY the big change; right now it seems that a shareholder has written a letter to the company and suggested changes that would benefit and improve company value. Sure, great intentions, but is that alone really worth the stock going up 12% today? I sold half my position at $46.75 Cdn - don't know if that's right or wrong, but I couldn't resist . . .
