A Call Option Allows the Buyer to.

Call options are derivatives that, when purchased, give investors the right to buy the underlying security at a specific price up berayun-ayun a specified expiry date. In this article, we will explain the use cases for buying or writing/selling call options, factors that influence call options pricing, and how call options work.

What Is a Call Option?

A
call option
is a contract that gives the buyer of the option the right to purchase a security, such as a specific stock, at a specific price (referred to as the
strike price). The other type of option is called a
put option, which allows the option holder to sell a specific security asset at a specified strike price. Both types of options have expiry dates. Equity/stock options are the most widely known by investors.

Many institutions deal in complex and unusual options on other types of financial securities. Call options can be bought and sold on a wide array of securities, including:

  • ETFs
  • Bonds
  • Interest rates
  • Futures
  • Indexes
  • Currencies
  • Swaps

Importantly, an investor who has bought a call option is not obligated to exercise it and purchase the underlying asset at the strike price. Investors have the choice of if and when they want to exercise options they own, or not exercise them. If, however, at expiry an option is in the money, the option will automatically be exercised at that time.

A distinction can be made between European-style options, which can be exercised only at expiry, and American-style options, which can be exercised at any time before expiry. In all cases though, options provide option buyers the opportunity to generate leveraged exposures to the underlying security.

How Call Options are Created

A call option contract is created on a securities exchange when an option writer/seller transacts with an option buyer. The option seller (also called the option writer) gives the buyer of the option the right, but not the obligation, to acquire a specified quantity of a security, such as a certain stock at a specified price. For equity call options, the quantity of shares tiap-tiap contract is 100, which means that the buyer of 1 option contract can exercise that option to buy 100 shares of the underlying stock at the specified strike price.

The Option Premium

The penanam modal that buys a call option contract pays a price, called the

option premium
, to the writer/seller of the call option contract.

The market value of options is determined by buyers and sellers, just like with stocks or other securities. However, options are derivatives of an underlying security.

In assessing fair option contract value consider:

  • The strike price of the option
  • The current price of the underlying security
  • The time to expiry for the option
  • The expected volatility of the underlying security

In considering these factors, buyers and writers/sellers of options establish a market for options. Frequently, but not always, options trade with much less liquidity than stocks, and the bid-ask spread may be wide on option prices.

Limit orders

are commonly used by options traders, although

market orders

are possible and feasible for options with smaller bid-ask spreads.

The option premium represents the price at which an option (a call or a put) is transacted between the option buyer and the option writer/seller.

How Call Options Work at Expiry

A call option will possess value at expiry if the price of the underlying security is above the strike price of the contract. In such a case, the call option is said to possess intrinsic value, or be trading
in the money. Here, exercising the option would allow the option holder to buy the stock at a price that is lower than that stock’s current market price, benefitting from doing so.

For the option writer/seller, the intrinsic value of the call option at expiry represents a cost. The call option buyer has the right to purchase the underlying security at the strike price, and the call option seller is obligated to sell the underlying security at the strike price. If the market value of the security is higher than the strike price at expiry, the call option writer/seller is required to deliver the underlying security to the call option buyer below its market value. If the option writer/seller doesn’horizon already own the underlying security, they will have to purchase it at market value and then sell it below market value (at the strike price).

At expiry, the intrinsic value of a call option represents a benefit to the option buyer and a cost to the option writer/seller. The value of these will offset each other. For example, if a call option is worth $200 to the option buyer at expiry (or at any time), it is simultaneously a $200 liability to the option seller.



Profits & Losses on Call Options

Created by the writer

Profits and losses on call option positions involve 2 components:

  • The option premium


  • The intrinsic value at expiry (if held to expiry)

To determine the kisa profit of an options trade, option buyers can subtract the cost of the option premium from the intrinsic value at expiry.

Net Profit = Intrinsic Value at Expiry – Cost of the Option Premium

Even if an option expires

in the money, the options buyer can suffer a jejala loss if the intrinsic value is less than the original cost of the option (the option premium). The breakeven price (see above tabel) is the point at which the intrinsic value of the option is equal to the option premium that was paid.

Breakeven Point: Option Premium Paid = Intrinsic Value of the Option

Once the breakeven point is reached, the higher the price of the call option, the greater the net profit will be for the option buyer. There is theoretically no upper limit to the price of the underlying security nor the potential profits for the option buyer.

The net profit/loss picture for the option writer/seller is effectively opposite that of the option buyer.


Option Buyer Profit (Loss) = Intrinsic Value at Expiry – Option Premium Price


Option Writer/Seller Profit (Loss) = Option Premium Price – Intrinsic Value at Expiry

Jala Profit/Loss Example

If an option expires with an intrinsic value of $11/share, and the option premium was $4/share, the owner of the option has earned a net profit of $700 (1 contract = 100 shares).

($11 x 100) – ($4 x 100) = +$700

The option writer/seller will realize a net loss of $700 in this scenario, after receiving an option premium worth $4/share, but incurring an $11/share cost at expiry.


($4 x 100) – ($11 x 100) = -$700

Of course, any trade commissions or other fees incurred represent incremental costs.



Note:
The above profit/loss formulas assume no commissions or fees are incurred

Call Option Example

A call option trade could look like this. Let’s assume it’s October, and an penanam modal believes that Walmart (
WMT
), whose stock is trading for $150/share, will have a widely successful Black Friday sales event that the market is not anticipating. In that case, the investor may want to buy a call option contract for Walmart stock that allows the investor to gain leveraged upside potential in case it turns out that Walmart does indeed have a stronger-than-expected Black Friday event, which would possibly result in a climbing share price. The current call option chain for Walmart, for options expiring mid-December, looks like this:

Call option example table from Walmart

Seeking Alpha

If the penyandang dana decides to acquire one contract with a strike price of $160, they will pay an option premium of $0.96 per share (the ask price), or $96 in total, for one option contract (which covers 100 shares of Walmart). The investor would then possess the right to buy 100 shares of Walmart at $160 each at any time through mid-December.

If, for example, Walmart shares were to trade at $165 by mid-December on the back of strong retail sales, the call option would have an intrinsic value of $5 masing-masing share and be worth $500 in total. After considering the cost of the option premium, the option buyer would realize a sauk-sauk profit of $404, excluding any commissions or fees. The writer of the call option, meanwhile, would suffer a net loss of $404.

If, however, Walmart does not trade above $160/share in mid-December, the option will expire worthless, and the option buyer will be out their $96 option premium. In this scenario, the option writer would pocket the $96 gain.

In an extreme scenario where Walmart shares close at $240/share in mid-December, the intrinsic value of the option would be $8,000. Here, the option writer would suffer significant losses at the hands of the option buyer.

Naked Call Writing vs. Covered Call Writing

As seen above, options writing/selling can expose investors to significant losses. In fact, since there is no theoretical ceiling to the price of a security, writing call options exposes the investor to the potential for unlimited losses. Investors who write call options can protect against such potential losses by employing what’s referred to as

covered call writing
.

Investors who own shares of the underlying security can sell calls that are “covered”. In essence, they are protected against significant losses because they can deliver the underlying security from their holdings, should the call option be exercised against them.

Another way to view this is from the perspective that the covered call writer earns profits from the underlying security that they hold if it rises in value. The gains from holding the underlying security serve to offset the losses on writing/selling the call option—so long as the quantity of the underlying security owned is not fewer than the shares represented by the option. If an penanam modal writes 2 call options on Walmart but owns 200 shares of Walmart stock, this investor is “covered”.

Call option writers/sellers who do titinada own the underlying security are referred to as

naked call writers
.

Closing a Call Option Position Before Expiry

Both buyers and sellers of options contracts can seek to close out their option positions prior to the expiration date of the contract. The buyer of an option contract can eliminate the position by selling it, and the writer/seller of an option contract can close out the position by repurchasing the option they sold originally.

The transaction price of the closing trade will determine whether the buyer or writer/seller of an option has generated a profit or loss. If an option buyer closes their position at a higher price than the option was purchased for, a profit has been made. If an option seller closes their position at a lower price than the option was originally sold for, they will have made a profit.


Option Buyer Profit (Loss) = Closing Trade (sell) Price – Original Purchase Price


Option Writer/Seller Profit (Loss) = Original Selling Price – Closing Trade (buy) Price

Understanding Call Option Market Values

The market value of a call option will continue to change throughout the lifetime of the option as market participants adjust to changes in:

  • The current price of the underlying security,

  • The expected volatility of the underlying security

  • The remaining time to expiry

Prior to their expiration date, options (both calls and puts) typically trade for more than their intrinsic value. This is due to what’s called the

time value


of the option
. If there is a lotre of time remaining until the expiry date of an option, this means there is a lot of time for the underlying security price to move in favor of the option owner. As time passes, an option’s


time value


decreases. At expiry, an option will be worth its

intrinsic value
. The market value of an option is equal to the sum of its intrinsic value and time value.


Option Market Value = Intrinsic Value + Time Value

Call Options Should Increase In Value

  • If the underlying security increases,

    while expected volatility and time to expiration remain unchanged

  • If expected volatility increases,

    while the underlying security price and time to expiration remain unchanged

Call Options Should Decrease In Value

  • If the underlying security decreases,

    while expected volatility and time to expiration remain unchanged

  • If expected volatility decreases,

    while the underlying security price and time to expiration remain unchanged

  • As time passes

    while the underlying security price and expected volatility remain unchanged

In reality, however, the underlying security price, expected volatility, and the time to expiration are often moving at the same time. The combination of these three elements contributes to the market’s determination of fair value for a call option. Investors who trade options may wish to utilize an option pricing teladan like Black Scholes.

4 Ways Investors Use Call Options


1. Speculate on a Price Increase

Investors that want to speculate on a price increase in an underlying security may benefit from buying call options on that security. While such an penyandang dana could alternatively just buy the underlying security, options offer leverage that increase potential % gains should the underlying security price move upward.

2. Invest Using Less Capital

Call options can allow investors to gain exposure to a security using less capital. For instance, purchasing 100 shares of a $1,000 stock would require $100,000 in capital. As an alternative, investors could gain exposure to 100 shares of that same stock by purchasing 1 option contract for a much smaller cash outlay. WARNING: Call option prices include time value, which erodes as time passes. Investors of call options will suffer losses if the underlying security trades rumah.

3. Exit Stocks at Specific Prices

An investor wishing to exit an existing stock position might choose to sell an option contract at a strike price equal to their take profit level. This can result in the generation of extra income, via option premiums, while waiting for the stock to reach the strike price. Note however that this investor remains exposed to losses on the underlying security from downward price movements.

4. Generate Income By Selling Out-of-the-Money Covered Calls

Investors wishing to generate income can regularly (or periodically) sell covered call options that are out of the money. By doing so, they can receive a steady stream of option premiums, so long as the underlying security doesn’horizon get called away. Investors trying to generate income through covered calls will often choose strike prices that are significantly higher than the current price of the underlying security, in order to minimize the likelihood of shares getting called away.

Bottom Line

Call options operate as derivatives of an underlying security and can offer investors an array of strategies across a wide array of securities. Leveraging one’s exposure to upward price movements in specific stocks or commodities is a core use case for buyers of call options, while other investors will enjoy the additional income they can generate by selling covered out-of-the-money calls from time to time.
