Maybe I am a little naive about this but at a risk of a flaming here it goes:
I have no issue with covered short selling. You borrowed something that you will pay back later. As long as this is the case then there is no problem.
However naked short selling is fooling the market to me. You are talking about creating supply temporarily out of thin air of shares. If there isn't a supply of shares available for you to sell then you shouldn't sell. Just like anything else in life - how can I sell what I don't have right of ownership borrowed or owned to? I can't sell a house and depress house prices so I can get a bargain now can I? I can't just magically create land and sell it to get cash now can I? Shares aren't tangible; somehow that makes people believe that this excludes them from that right. The right of every long holder to me is to do what they like with their supply including the right to hold it from the market.
In the end it swamps the market with supply that doesn't exist. I can't see how that is an efficient market. It seems like an easy way to play on peoples sentiment and make a quick buck. Sure the smart traders are laughing, but the average person just wanting to be responsible, invest and retire does not like his asset being devalued by non-existant supply of stock.
Good post.
That is exactly what I think
