Short selling, also known as going short, is the opposite of going long, where you buy first and sell later. In a short sale, you sell first and buy later (after borrowing). The short seller borrows shares from a broker, sells them when the price is high, then buys them back at a lower price to return to the lender. The lower the price is driven, the more profit the short seller makes.
