One of my shorting stocks, page-16

VH,
Sure, i'm not arguing about the causes of these bubbles, but how they are exacerbated and cruelly played out. There is plenty of reading about this out there. I am also not referring to any individual in particular but the concept of shorting in itself.
Shouldn't share investing, even trading, be about reward for productivity? Isn't the idea of buying a share to gain growth on the perceived or actual gain of productivity? Shorting can only be about greed without the concept that productivity = reward.

I have no problem with a CFD bet between a trading house and a punter. That is an agreement between two parties on price movement, but on market shares is a different story, as shares are a chunk of the company.
