Speculation

A seller intentionally takes on directional risk in the belief that the value of the shorted asset will fall.

Hedging

Hedging often represents a means of minimizing the risk from a more complex set of transactions.

Examples of this are:

• A farmer who has just planted his wheat wants to lock in the price at which he can sell after the harvest. He would take a short position in wheat futures.
• A market maker in corporate bonds is constantly trading bonds when clients want to buy or sell. This can create substantial bond positions. The largest risk is that interest rates overall move. The trader can hedge this risk by selling government bonds short against his long positions in corporate bonds. In this way, the risk that remains is credit risk of the corporate bonds.
• an options trader may short shares in order to remain delta neutral so that he is not exposed to risk from price movements in the stocks that underlie his options

Arbitrage

A short seller may be trying to benefit from market inefficiencies arising from the mispricing of certain products. Examples of this are

• An arbitrageur who buys long futures contracts on a US Treasury security, and sells short the underlying US Treasury security.

Against the box

One variant of selling short involves a long position. "Selling short against the box" is holding a long position on which one enters a short sell order. The term box alludes to the days when a safe deposit box 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). Whether prices increase or decrease, the short position balances the long position and the profits are locked in (less brokerage fees and short financing costs).

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.

The regulatory response

In the US, Regulation SHO was the SEC's first update to short selling restrictions since 1938. It established "locate" and "close-out" requirements for broker-dealers, in an effort to curb naked short selling. Compliance with the regulation began on January 3, 2005.

In the US, initial public offering s (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 brokerages that specialize in penny stock s (referred to colloquially as bucket shops) have used the lack of short selling during this month to pump and dump thinly traded IPOs. Canada and other countries do allow selling IPOs (including U.S. IPOs) short.

In the UK, the Financial Services Authority had a moratorium on short selling 29 leading financial stocks, effective from 2300 GMT, 19 September 2008 until 16 January 2009.

After the ban was lifted, John McFall, chairman of the Treasury Select Committee, House of Commons, made clear in public statements and a letter to the FSA that he believed it ought to be extended.

In the US, a similar response was made by the Securities and Exchange Commission with a ban on short selling on 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.

Soon thereafter, between 19 and 21 September 2008, Australia temporarily banned short selling,, and later placed an indefinite ban on naked short selling . The ban on short selling was further extended for another 28 days on 21 October 2008.Germany, Ireland, Switzerland and Canada banned short selling leading financial stocks, and France, The Netherlands and Belgium banned naked short selling leading financial stocks..

By contrast, Chinese regulators have responded by allowing short selling, along with a package of other market reforms.

An assessment of the effect of a ban on short-selling that was enacted in many countries in the fall of 2008 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. By December, countries in Europe were considering to remove the ban, while the ban in the US was already lifted in October 2008. The SEC [http://paulwilkinson.com/wiki/index.php?title=Short_Selling_Rule#SEC_Proposals_to_Restrict_Short_Sales proposed new restrictions on short selling] in April 2009.
