(FINANCE) borrowing securities for immediate sale, in anticipation of a sharp decline. Short selling requires strong nerves and excellent market timing; it also requires the ability to locate tranches of securities to borrow. If the short seller is correct, then she can buy back the securities at a much lower price, and lock in very high profits with very little initial investment.

Closely related to the concept of a short position. However, a short position includes buying put options (for example), while a long position could include short selling put options. So they are not exactly the same.

If a short sellers are wrong about the market, they are left hastily covering shorts, or buying the item they borrowed at a HIGHER price than they sold it for.
Jim Fisk was a master of the short squeeze; he appeared to cooperate with short selling until he was able to call in loans, forcing his counterparties to cover their shorts.

Get the short selling mug.
1) To sell something (usually a stock) that one does not own, with the anticipation that the item's value will decline and they will be able to buy it back at a later date for a lesser price.
2) To deny someone credit that they deserve. This is generally something a person does to him/herself.
I sold your sister short last year for $100, then bought her back this year for a can of Skoal and a junior bacon cheeseburger. Damn that rag has really started to circle the drain.
You: "So you're not going to let me beat it up, are you?"
Girl: "Nope, sorry. Denied! But don't sell yourself short...3 inches isn't really that small. At least you've got my chihuahua beat...I think."
