Could anyone in the know explain how "shorting" works?
Imagine you think widgets that are worth $1 today are going to be worth $0.50 tomorrow. You say to me, "Hey jpdb, can I borrow 100 widgets and give them back to you tomorrow?" I say sure and you turn around and sell those widgets. Tomorrow, we meet up and you take your $100 and buy 100 widgets for the new price of $0.50 each. You return the 100 widgets you borrowed and you now have $50 in your pocket. In this example you have "shorted" widgets.
