Short sell means a sell without owing it... means you are not having the stuff ....but you are making sell to it.....such type of sell you may perform in intraday cash,future and options trading too . In options trading such type of trade is named as put options.
In delivery trades you can not sell short your stuff . for delivery trades first you have to buy it then you may sell it .
But in intraday trading you can sell first and can buy the shares at lower price later on Short selling is beneficial to get quick return as price falls rapidly but climbs slowly slowly. So if you are confident about falling of prices then you may go for short selling and cover it before market closing .Please remember share trading is a high risk /high rewarding profession .So enter in market when you are having sufficient knowledge
