Exercise (options)

Last updated

The owner of an option contract has the right to exercise it, and thus require that the financial transaction specified by the contract is to be carried out immediately between the two parties, whereupon the option contract is terminated. When exercising a call option, the owner of the option purchases the underlying shares (or commodities, fixed interest securities, etc.) at the strike price from the option seller, while for a put option, the owner of the option sells the underlying to the option seller, again at the strike price. [1]

Styles

The option style, as specified in the contract, determines when, how, and under what circumstances, the option holder may exercise it. It is at the discretion of the owner whether (and in some circumstances when) to exercise it.[ citation needed ]

Settlement

The option contract specifies the manner in which the contract is to be settled.

Considerations

The following guidelines determine whether and when to exercise an option: [3]

  1. An option should only be exercised if it is in the money by at least as much as the fees associated with the underlying transaction (e.g. the fee for subsequently selling an underlying which has been physically delivered). The exercise usually costs money as well.
  2. In most cases, options should not be exercised before expiration because doing so gives away inherent value. Selling them would almost invariably yield more.
  3. For an American-style call option, early exercise is a possibility whenever the benefits of being long the underlier outweigh the cost of surrendering the option early. For instance, on the day before an ex-dividend date, it may make sense to exercise an equity call option early in order to collect the dividend. In general, equity call options should only be exercised early on the day before an ex-dividend date, and then only for deep in-the-money options.
  4. For an American-style put option, early exercise is a possibility for deep in-the-money options. In this case, it may make sense to exercise the option early in order to obtain the intrinsic value (K-S) earlier so that it can start to earn interest immediately. This is somewhat more likely to be worthwhile if there is no ex-dividend date (which would probably cause the price of the underlying to fall further) between now and the expiry date.

Early exercise strategy

A common strategy among professional option traders is to sell large quantities of in-the-money calls just prior to an ex-dividend date. Quite often, non-professional option traders may not understand the benefit of exercising a call option early,[ citation needed ] and therefore may unintentionally forgo the value of the dividend. The professional trader may only be 'assigned' on a portion of the calls, and therefore profits by receiving a dividend on the stock used to hedge the calls that are not exercised.

Assignment and clearing

Assignment occurs when an option holder exercises his option by notifying his broker, who then notifies the Options Clearing Corporation (OCC). The OCC fulfills the contract, then selects, randomly, a member firm who was short the same option contract; afterwards the firm will be notified by the OCC. The firm then carries out its obligation, and then selects a customer, either randomly, first-in, first-out, or some other equitable method who was short the option, for assignment. That customer is assigned the exercise requiring him to fulfill the obligation that he agreed to when he wrote the option.[ citation needed ]

Exercise by exception

In the U.S., for the convenience of brokers, who would otherwise have to request exercise of all in the money options, the Options Clearing Corporation will automatically exercise any option that is set to expire in the money by 1 cent or more. This is called "exercise by exception". A broker or holder of such options may request that they not be exercised by exception. The price of the underlying security used to determine the need for exercise by exception is the price of the regular-hours trade reported last to the OCC at or before 4:01:30 pm ET on the day before expiration. This trade will have occurred during normal trading hours, i.e., before 4:00 pm. It can be any size and come from any participating exchange. The OCC reports this price tentatively at 4:15 pm, but, to allow time for exchanges to correct errors the OCC does not make the price official until 5:30 pm. [4]

In finance, a call option, often simply labeled a "call", is a contract between the buyer and the seller of the call option to exchange a security at a set price. The buyer of the call option has the right, but not the obligation, to buy an agreed quantity of a particular commodity or financial instrument from the seller of the option at or before a certain time for a certain price. This effectively gives the owner a long position in the given asset. The seller is obliged to sell the commodity or financial instrument to the buyer if the buyer so decides. This effectively gives the seller a short position in the given asset. The buyer pays a fee for this right. The term "call" comes from the fact that the owner has the right to "call the stock away" from the seller.

In finance, a put or put option is a derivative instrument in financial markets that gives the holder the right to sell an asset, at a specified price, by a specified date to the writer of the put. The purchase of a put option is interpreted as a negative sentiment about the future value of the underlying stock. The term "put" comes from the fact that the owner has the right to "put up for sale" the stock or index.

In finance, the style or family of an option is the class into which the option falls, usually defined by the dates on which the option may be exercised. The vast majority of options are either European or American (style) options. These options—as well as others where the payoff is calculated similarly—are referred to as "vanilla options". Options where the payoff is calculated differently are categorized as "exotic options". Exotic options can pose challenging problems in valuation and hedging.

<span class="mw-page-title-main">Strike price</span> Options fixed price to exercise it on the expiration date

In finance, the strike price of an option is a fixed price at which the owner of the option can buy, or sell, the underlying security or commodity. The strike price may be set by reference to the spot price, which is the market price of the underlying security or commodity on the day an option is taken out. Alternatively, the strike price may be fixed at a discount or premium.

<span class="mw-page-title-main">Futures contract</span> Standard forward contract

In finance, a futures contract 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 transacted is usually a commodity or financial instrument. The predetermined price of the contract is known as the forward price. The specified time in the future when delivery and payment occur is known as the delivery date. Because it derives its value from the value of the underlying asset, a futures contract is a derivative.

In finance, an equity derivative is a class of derivatives whose value is at least partly derived from one or more underlying equity securities. Options and futures are by far the most common equity derivatives, however there are many other types of equity derivatives that are actively traded.

A rights issue or rights offer is a dividend of subscription rights to buy additional securities in a company made to the company's existing security holders. When the rights are for equity securities, such as shares, in a public company, it can be a non-dilutive pro rata way to raise capital. Rights issues are typically sold via a prospectus or prospectus supplement. With the issued rights, existing security-holders have the privilege to buy a specified number of new securities from the issuer at a specified price within a subscription period. In a public company, a rights issue is a form of public offering.

In finance, the intrinsic value of an asset or security is its value as calculated with regard to an inherent, objective measure; this is in distinction to its price, which is determined relative to other similar assets.

In finance, the expiration date of an option contract is the last date on which the holder of the option may exercise it according to its terms. In the case of options with "automatic exercise", the net value of the option is credited to the long and debited to the short position holders.

Pin risk occurs when the market price of the underlier of an option contract at the time of the contract's expiration is close to the option's strike price. In this situation, the underlier is said to have pinned. The risk to the writer (seller) of the option is that they cannot predict with certainty whether the option will be exercised or not. So the writer cannot hedge their position precisely and may end up with a loss or gain. There is a chance that the price of the underlier may move adversely, resulting in an unanticipated loss to the writer. In other words, an option position may result in a large, undesired risky position in the underlier immediately after expiration, regardless of the actions of the writer.

<span class="mw-page-title-main">Option (finance)</span> Right to buy or sell a certain thing at a later date at an agreed price

In finance, an option is a contract which conveys to its owner, the holder, the right, but not the obligation, to buy or sell a specific quantity of an underlying asset or instrument at a specified strike price on or before a specified date, depending on the style of the option. Options are typically acquired by purchase, as a form of compensation, or as part of a complex financial transaction. Thus, they are also a form of asset and have a valuation that may depend on a complex relationship between underlying asset price, time until expiration, market volatility, the risk-free rate of interest, and the strike price of the option. Options may be traded between private parties in over-the-counter (OTC) transactions, or they may be exchange-traded in live, public markets in the form of standardized contracts.

In finance, a perpetual futures contract, also known as a perpetual swap, is an agreement to non-optionally buy or sell an asset at an unspecified point in the future. Perpetual futures are cash-settled, and differ from regular futures in that they lack a pre-specified delivery date, and can thus be held indefinitely without the need to roll over contracts as they approach expiration. Payments are periodically exchanged between holders of the two sides of the contracts, long and short, with the direction and magnitude of the settlement based on the difference between the contract price and that of the underlying asset, as well as, if applicable, the difference in leverage between the two sides.
