Re: Selling airline stocks short --
If enough people do that, it will almost guarantee that they'll lose money and the stocks will go back up. You make money with short selling when everyone else thinks a stock is going up. Because when everyone thinks it's going up, it will have reached its peak.
It's quite possible that airline stocks will take a real tumble now, but in order to sell short, you have to find a buyer, and if everyone is pessimistic, you will have to pay quite a premium to find a buyer for your short sell. Then, when the stocks stabilize and you realize you might lose money, you'll have to enter the market and buy those suckers -- which only lets drive their prices UP more

God I love the stock market. It is virtually a law of how it works that when a huge majority think it will do one thing, it will actually do the opposite!
