Concept


Physical shorting with borrowed securities

To profit from a decrease in the price of a security, a short seller can borrow the security and sell it, expecting that it will be cheaper to repurchase in the future. When the seller decides that the time is right (or when the lender recalls the securities), the seller buys the same number of equivalent securities and returns them to the lender. The act of buying back the securities that were sold short is called covering the short, covering the position or simply covering. A short position can be covered at any time before the securities are due to be returned. Once the position is covered, the short seller is not affected by subsequent rises or falls in the price of the securities, for it already holds the securities that it will return to the lender. The process relies on the fact that the securities (or the other assets being sold short) are
fungible In economics, fungibility is the property of a good or a commodity whose individual units are essentially interchangeable, and each of whose parts is indistinguishable from any other part. Fungible tokens can be exchanged or replaced; for exa ...
. An investor therefore "borrows" securities in the same sense as one borrows cash, where the borrowed cash can be freely disposed of and different bank notes or coins can be returned to the lender. This can be contrasted with the sense in which one borrows a bicycle, where the same bicycle must be returned, not merely one that is the same model. Because the price of a share is theoretically unlimited, the potential losses of a short-seller are also theoretically unlimited.


Worked example of a profitable short sale

Shares in ACME Inc. currently trade at $10 per share. # A short seller borrows from a lender 100 shares of ACME Inc., and immediately sells them for a total of $1,000. # Subsequently, the price of the shares falls to $8 per share. # Short seller now buys 100 shares of ACME Inc. for $800. # Short seller returns the shares to the lender, who must accept the return of the same number of shares as was lent despite the fact that the market value of the shares has decreased. # Short seller keeps as its profit the $200 difference between the price at which the short seller sold the borrowed shares and the lower price at which the short seller purchased the equivalent shares (minus borrowing fees paid to the lender).


Worked example of a loss-making short sale

Shares in ACME Inc. currently trade at $10 per share. # A short seller borrows 100 shares of ACME Inc., and sells them for a total of $1,000. # Subsequently, the price of the shares rises to $25 per share. # Short seller is required to return the shares, and is compelled to buy 100 shares of ACME Inc. for $2,500. # Short seller returns the shares to the lender, who accepts the return of the same number of shares as was lent. # Short seller incurs as a loss the $1,500 difference between the price at which he sold the borrowed shares and the higher price at which the short seller had to purchase the equivalent shares (plus any borrowing fees).


Synthetic shorting with derivatives

"Shorting" or "going short" (and sometimes also "short selling") also refer more broadly to any transaction used by an investor to profit from the decline in price of a borrowed asset or financial instrument. Derivatives contracts that can be used in this way include
futures Futures may mean: Finance *Futures contract, a tradable financial derivatives contract *Futures exchange, a financial market where futures contracts are traded * ''Futures'' (magazine), an American finance magazine Music * ''Futures'' (album), a ...
, options, and swaps. These contracts are typically cash-settled, meaning that no buying or selling of the asset in question is actually involved in the contract, although typically one side of the contract will be a broker that will effect a back-to-back sale of the asset in question in order to hedge their position.


History

The practice of short selling was likely invented in 1609 by Dutch businessman Isaac Le Maire, a sizeable shareholder of the

has written extensively on the development of sophisticated contracts on the Amsterdam Stock Exchange in the seventeenth century, including short sale contracts. Short selling can exert downward pressure on the underlying stock, driving down the price of shares of that security. This, combined with the seemingly complex and hard-to-follow tactics of the practice, has made short selling a historical target for criticism. At various times in history, governments have restricted or banned short selling. The London banking house of Neal, James, Fordyce and Down collapsed in June 1772, precipitating a major crisis that included the collapse of almost every private bank in Scotland, and a liquidity crisis in the two major banking centres of the world, London and Amsterdam.

is the practice of short-selling a tradable asset without first borrowing the security or ensuring that the security can be borrowed – it was this practice that was commonly restricted. Investors argued that it was the weakness of financial institutions, not short-selling, that drove stocks to fall. In September 2008, the Securities Exchange Commission in the United States abruptly banned short sales, primarily in financial stocks, to protect companies under siege in the stock market. That ban expired several weeks later as regulators determined the ban was not stabilizing the price of stocks. Temporary short-selling bans were also introduced in the

Germany placed a ban on naked short selling of certain euro zone securities in 2010. Spain, Portugal and Italy introduced short selling bans in 2011 and again in 2012. During the COVID-19 pandemic, shorting was severely restricted or temporarily banned, with European market watchdogs tightening the rules on short selling "in an effort to stem the historic losses arising from the coronavirus pandemic". Worldwide, economic regulators seem inclined to restrict short selling to decrease potential downward price cascades. Investors continue to argue this only contributes to market inefficiency.

, who is usually holding the securities for another investor who owns the securities; the broker himself seldom purchases the securities to lend to the short seller. The lender does not lose the right to sell the securities while they have been lent, as the broker usually holds a large pool of such securities for a number of investors which, as such securities are fungible, can instead be transferred to any buyer. In most market conditions there is a ready supply of securities to be borrowed, held by pension funds, mutual funds and other investors.


Shorting stock in the U.S.

To sell stocks short in the U.S., the seller must arrange for a broker-dealer to confirm that it can deliver the shorted securities. This is referred to as a '' locate''. Brokers have a variety of means to borrow stocks to facilitate locates and make good on delivery of the shorted security. The vast majority of stocks borrowed by U.S. brokers come from loans made by the leading custody banks and fund management companies (see list below). Institutions often lend out their shares to earn extra money on their investments. These institutional loans are usually arranged by the custodian who holds the securities for the institution. In an institutional stock loan, the borrower puts up cash collateral, typically 102% of the value of the stock. The cash collateral is then invested by the lender, who often rebates part of the interest to the borrower. The interest that is kept by the lender is the compensation to the lender for the stock loan. Brokerage firms can also borrow stocks from the accounts of their own customers. Typical margin account agreements give brokerage firms the right to borrow customer shares without notifying the customer. In general, brokerage accounts are only allowed to lend shares from accounts for which customers have ''debit balances'', meaning they have borrowed from the account. SEC Rule 15c3-3 imposes such severe restrictions on the lending of shares from cash accounts or excess margin (fully paid for) shares from margin accounts that most brokerage firms do not bother except in rare circumstances. (These restrictions include that the broker must have the express permission of the customer and provide collateral or a letter of credit.) Most brokers allow retail customers to borrow shares to short a stock only if one of their own customers has purchased the stock on

. Alternatively, these can also be expressed as the short interest ratio, which is the number of shares ''legally'' sold short as a multiple of the average daily volume. These can be useful tools to spot trends in stock price movements but for them to be reliable, investors must also ascertain the number of shares brought into existence by naked shorters. Speculators are cautioned to remember that for every share that has been shorted (owned by a new owner), a 'shadow owner' exists (i.e., the original owner) who also is part of the universe of owners of that stock, i.e., despite having no voting rights, he has not relinquished his interest and some rights in that stock.


Securities lending

When a security is sold, the seller is contractually obliged to deliver it to the buyer. If a seller sells a security short without owning it first, the seller must borrow the security from a third party to fulfill its obligation. Otherwise, the seller ''fails to deliver,'' the transaction does not settle, and the seller may be subject to a claim from its

Sources of short interest data

Time delayed short interest data (for ''legally'' shorted shares) is available in a number of countries, including the US, the UK, Hong Kong, and Spain. The number of stocks being shorted on a global basis has increased in recent years for various structural reasons (e.g., the growth of 130/30 type strategies, short or bear ETFs). The data is typically delayed; for example, the NASDAQ requires its

member firms to report data on the 15th of each month, and then publishes a compilation eight days later. Some market data providers (like Data Explorers and SunGard Financial Systems) believe that stock lending data provides a good proxy for short interest levels (excluding any naked short interest). SunGard provides daily data on short interest by tracking the proxy variables based on borrowing and lending data it collects.


Short selling terms

Days to Cover (DTC) is the relationship between the number of shares in a given equity that has been ''legally'' short-sold and the number of days of typical trading that it would require to 'cover' all legal short positions outstanding. For example, if there are ten million shares of XYZ Inc. that are currently legally short-sold and the average daily volume of XYZ shares traded each day is one million, it would require ten days of average trading for all legal short positions to be covered (10 million / 1 million). Short Interest relates the number of shares in a given equity that have been legally shorted divided by the total shares outstanding for the company, usually expressed as a percent. For example, if there are ten million shares of XYZ Inc. that are currently legally short-sold, and the total number of shares issued by the company is one hundred million, the Short Interest is 10% (10 million / 100 million). If, however, shares are being created through naked short selling, "fails" data must be accessed to assess accurately the true level of short interest. Borrow cost is the fee paid to a securities lender for borrowing the stock or other security. The cost of borrowing the stock is usually negligible compared to fees paid and interest accrued on the margin account – in 2002, 91% of stocks could be shorted for less than a 1% fee per annum, generally lower than interest rates earned on the margin account. However, certain stocks become "hard to borrow" as stockholders willing to lend their stock become more difficult to locate. The cost of borrowing these stocks can become significant – in February 2001, the cost to borrow (short)

Naked short selling

A naked short sale occurs when a security is sold short without borrowing the security within a set time (for example, three days in the US.) This means that the buyer of such a short is buying the short-seller's promise to deliver a share, rather than buying the share itself. The short-seller's promise is known as a hypothecated share. When the holder of the underlying stock receives a dividend, the holder of the hypothecated share would receive an equal

Fees

When a broker facilitates the delivery of a client's short sale, the client is charged a fee for this service, usually a standard commission similar to that of purchasing a similar security. If the short position begins to move against the holder of the short position (i.e., the price of the security begins to rise), money is removed from the holder's cash balance and moved to their margin balance. If short shares continue to rise in price, and the holder does not have sufficient funds in the cash account to cover the position, the holder begins to borrow on margin for this purpose, thereby accruing margin interest charges. These are computed and charged just as for any other margin debit. Therefore, only margin accounts can be used to open a short position. When a security's

passes, the dividend is deducted from the shortholder's account and paid to the person from whom the stock is borrowed. For some brokers, the short seller may not earn interest on the proceeds of the short sale or use it to reduce outstanding margin debt. These brokers may not pass this benefit on to the retail client unless the client is very large. The interest is often split with the lender of the security.


Dividends and voting rights

Where shares have been shorted and the company that issues the shares distributes a dividend, the question arises as to who receives the dividend. The new buyer of the shares, who is the ''holder of record'' and holds the shares outright, receives the dividend from the company. However, the lender, who may hold its shares in a

and is unlikely to be aware that these particular shares are being lent out for shorting, also expects to receive a dividend. The short seller therefore pays the lender an amount equal to the dividend to compensate—though technically, as this payment does not come from the company, it is not a dividend. The short seller is therefore said to be ''short the dividend''. A similar issue comes up with the voting rights attached to the shorted shares. Unlike a dividend, voting rights cannot legally be synthesized and so the buyer of the shorted share, as the holder of record, controls the voting rights. The owner of a margin account from which the shares were lent agreed in advance to relinquish voting rights to shares during the period of any short sale. As noted earlier, victims of naked shorting sometimes report that the number of votes cast is greater than the number of shares issued by the company.


Markets

Transactions in financial derivatives such as options and futures have the same name but have different overlaps, one notable overlap is having an equal "negative" amount in the position. However, the practice of a short position in derivatives is completely different. Derivatives are contracts between two parties, a buyer and seller. Each trade results in a "long" (buyer's position) and a "short" (seller's position).


Futures and options contracts

When trading
futures contract In finance, a futures contract (sometimes called a futures) is a standardized legal contract to buy or sell something at a predetermined price for delivery at a specified time in the future, between parties not yet known to each other. The asset ...
s, being 'short' means having the legal obligation to deliver something at the expiration of the contract, although the holder of the short position may alternately buy back the contract prior to expiration instead of making delivery. Short futures transactions are often used by producers of a commodity to fix the future price of goods they have not yet produced. Shorting a futures contract is sometimes also used by those holding the underlying asset (i.e. those with a long position) as a temporary hedge against price declines. Shorting futures may also be used for speculative trades, in which case the investor is looking to profit from any decline in the price of the futures contract prior to expiration. An investor can also purchase a put option, giving that investor the right (but not the obligation) to sell the underlying asset (such as shares of stock) at a fixed price. In the event of a market decline, the option holder may exercise these put options, obliging the counterparty to buy the underlying asset at the agreed upon (or "strike") price, which would then be higher than the current quoted spot price of the asset.


Currency

Selling short on the currency markets is different from selling short on the stock markets. Currencies are traded in pairs, each currency being priced in terms of another. In this way, selling short on the currency markets is identical to going long on stocks. Novice traders or stock traders can be confused by the failure to recognize and understand this point: a contract is always long in terms of one medium and short another. When the exchange rate has changed, the trader buys the first currency again; this time he gets more of it, and pays back the loan. Since he got more money than he had borrowed initially, he makes money. The reverse can also occur. An example of this is as follows: Let us say a trader wants to trade with the US dollar and the
Indian rupee The Indian rupee (symbol: ₹; code: INR) is the official currency in the republic of India. The rupee is subdivided into 100 '' paise'' (singular: ''paisa''), though as of 2022, coins of denomination of 1 rupee are the lowest value in use wh ...
currencies. Assume that the current market rate is US$1 to Rs. 50 and the trader borrows Rs. 100. With this, he buys US$2. If the next day, the conversion rate becomes US$1 to Rs. 51, then the trader sells his US$2 and gets Rs. 102. He returns Rs. 100 and keeps the Rs. 2 profit (minus fees). One may also take a short position in a currency using

or options; the preceding method is used to bet on the spot price, which is more directly analogous to selling a stock short.


Risks

Note: this section does not apply to currency markets. Short selling is sometimes referred to as a "negative income investment strategy" because there is no potential for dividend income or interest income. Stock is held only long enough to be sold pursuant to the contract, and one's return is therefore limited to short term capital gains, which are taxed as ordinary income. For this reason, buying shares (called "going long") has a very different risk profile from selling short. Furthermore, a "long's" losses are limited because the price can only go down to zero, but gains are not, as there is no limit, in theory, on how high the price can go. On the other hand, the short seller's possible gains are limited to the original price of the stock, which can only go down to zero, whereas the loss potential, again in theory, has no limit. For this reason, short selling probably is most often used as a

'' with their stockbroker after selling a stock short—an order to the brokerage to cover the position if the price of the stock should rise to a certain level. This is to limit the loss and avoid the problem of unlimited liability described above. In some cases, if the stock's price skyrockets, the stockbroker may decide to cover the short seller's position immediately and without his consent to guarantee that the short seller can make good on his debt of shares. Short sellers must be aware of the potential for a

; others may be forced to cover, subject to the terms under which they borrowed the stock, if the person who lent the stock wishes to sell and take a profit. Since covering their positions involves buying shares, the short squeeze causes an ever further rise in the stock's price, which in turn may trigger additional covering. Because of this, most short sellers restrict their activities to heavily traded stocks, and they keep an eye on the "short interest" levels of their short investments. Short interest is defined as the total number of shares that have been ''legally'' sold short, but not covered. A short squeeze can be deliberately induced. This can happen when large investors (such as companies or wealthy individuals) notice significant short positions, and buy many shares, with the intent of selling the position at a profit to the short sellers, who may be panicked by the initial uptick or who are forced to cover their short positions to avoid margin calls. Another risk is that a given stock may become "hard to borrow". As defined by the SEC and based on lack of availability, a broker may charge a hard to borrow fee daily, without notice, for any day that the SEC declares a share is hard to borrow. Additionally, a broker may be required to cover a short seller's position at any time ("buy in"). The short seller receives a warning from the broker that he is "failing to deliver" stock, which leads to the buy-in. Because short sellers must eventually deliver the shorted securities to their broker, and need money to buy them, there is a credit risk for the broker. The penalties for failure to deliver on a short selling contract inspired financier Daniel Drew to warn: "He who sells what isn't his'n, Must buy it back or go to pris'n." To manage its own risk, the broker requires the short seller to keep a

account, and charges interest of between 2% and 8% depending on the amounts involved. In 2011, the eruption of the massive China stock frauds on North American equity markets brought a related risk to light for the short seller. The efforts of research-oriented short sellers to expose these frauds eventually prompted NASDAQ, NYSE and other exchanges to impose sudden, lengthy trading halts that froze the values of shorted stocks at artificially high values. Reportedly in some instances, brokers charged short sellers excessively large amounts of interest based on these high values as the shorts were forced to continue their borrowings at least until the halts were lifted. Short sellers tend to temper overvaluation by selling into exuberance. Likewise, short sellers are said to provide price support by buying when negative sentiment is exacerbated after a significant price decline. Short selling can have negative implications if it causes a premature or unjustified share price collapse when the fear of cancellation due to bankruptcy becomes contagious.


Strategies


Hedging

Arbitrage

Against the box

One variant of selling short involves a long position. "Selling short against the box" consists of holding a long position on which the shares have already risen, whereupon one then enters a short sell order for an equal number of shares. The term ''box'' alludes to the days when a

was used to store (long) shares. The purpose of this technique is to lock in paper profits on the long position without having to sell that position (and possibly incur taxes if said position has appreciated). Once the short position has been entered, it serves to balance the long position taken earlier. Thus, from that point in time, the profit is locked in (less brokerage fees and short financing costs), regardless of further fluctuations in the underlying share price. For example, one can ensure a profit in this way, while delaying sale until the subsequent tax year. U.S. investors considering entering into a "short against the box" transaction should be aware of the tax consequences of this transaction. Unless certain conditions are met, the IRS deems a "short against the box" position to be a "constructive sale" of the long position, which is a taxable event. These conditions include a requirement that the short position be closed out within 30 days of the end of the year and that the investor must hold their long position, without entering into any hedging strategies, for a minimum of 60 days after the short position has been closed.

) that a short sale could only be made when the price of a particular stock was higher than the previous trade price. The uptick rule aimed to prevent short sales from causing or exacerbating market price declines. In January 2005, The Securities and Exchange Commission enacted Regulation SHO to target abusive naked short selling. Regulation SHO was the SEC's first update to short selling restrictions since the uptick rule in 1938. The regulation contains two key components: the "locate" and the "close-out". The locate component attempts to reduce failure to deliver securities by requiring a broker possess or have arranged to possess borrowed shares. The close out component requires that a broker be able to deliver the shares that are to be shorted. In the US, initial public offers (IPOs) cannot be sold short for a month after they start trading. This mechanism is in place to ensure a degree of price stability during a company's initial trading period. However, some

. Canada and other countries do allow selling IPOs (including U.S. IPOs) short. The Securities and Exchange Commission initiated a temporary ban on short selling of 799 financial stocks from 19 September 2008 until 2 October 2008. Greater penalties for naked shorting, by mandating delivery of stocks at clearing time, were also introduced. Some state governors have been urging state pension bodies to refrain from lending stock for shorting purposes. An assessment of the effect of the temporary ban on short-selling in the United States and other countries in the wake of the financial crisis showed that it had only "little impact" on the movements of stocks, with stock prices moving in the same way as they would have moved anyhow, but the ban reduced volume and liquidity.
