In finance, short selling (also known as shorting or going short) is the practice of selling assets, usually securities, that have been borrowed from a third party (usually a broker) with the intention of buying identical assets back at a later date to return to that third party. The basic principle followed is that selling something high now, to buy lower later, is profitable. The short seller hopes to profit from a decline in the price of the assets between the sale and the repurchase, as the seller will pay less to buy the assets than it received on selling them. The short seller will incur a loss if the price of the assets rises (as it will have to buy them at a higher price than it sold them), and the loss that can be incurred by a short seller is only limited by the total strike price. Other costs of shorting may include a fee for borrowing the assets and payment of any dividends paid on the borrowed assets. "Shorting" and "going short" also refer to entering into any derivative or other contract under which the investor similarly profits from a fall in the value of an asset. Mathematically, short selling is equivalent to buying a negative amount of the assets.

Short selling is almost always conducted with assets traded in public securities, commodities or currency markets, as on such markets the amount being made or lost can be monitored in real time and it is generally possible to buy back the borrowed assets whenever required. Because such assets are fungible, any assets of the same type bought on those markets can be used to return to the lender.

Going short can be contrasted with the more conventional practice of "going long", whereby an investor profits from any increase in the price of the asset.
