A call option gives the holder the right, but not the obligation, to buy the underlying security at the strike price on or before expiration. A call option will therefore become more valuable as the underlying security rises in price calls have a positive delta. A long call can be used to speculate on the price of the underlying rising, since it has unlimited upside potential but the maximum loss is the premium price paid for the option.

Opposite to call options, a put gives the holder the right, but not the obligation, to instead sell the underlying stock at the strike price on or before expiration. A long put, therefore, is a short position in the underlying security, since the put gains value as the underlying's price falls they have a negative delta.

Protective puts can be purchased as a sort of insurance, providing a price floor for investors to hedge their positions. American options can be exercised at any time between the date of purchase and the expiration date. European options are different from American options in that they can only be exercised at the end of their lives on their expiration date. The distinction between American and European options has nothing to do with geography, only with early exercise.

Many options on stock indexes are of the European type. Because the right to exercise early has some value, an American option typically carries a higher premium than an otherwise identical European option. This is because the early exercise feature is desirable and commands a premium.

Options contracts usually represent shares of the underlying security. The buyer pays a premium fee for each contract. The premium is partially based on the strike price or the price for buying or selling the security until the expiration date.

Another factor in the premium price is the expiration date. Just like with that carton of milk in the refrigerator, the expiration date indicates the day the option contract must be used. The underlying asset will determine the use-by date.

For stocks, it is usually the third Friday of the contract's month. Options spreads are strategies that use various combinations of buying and selling different options for the desired risk-return profile. Spreads are constructed using vanilla options , and can take advantage of various scenarios such as high- or low-volatility environments, up- or down-moves, or anything in-between.

Spread strategies can be characterized by their payoff or visualizations of their profit-loss profile, such as bull call spreads or iron condors. The options market uses the term the " Greeks " to describe the different dimensions of risk involved in taking an options position, either in a particular option or a portfolio.

These variables are called Greeks because they are typically associated with Greek symbols. Each risk variable is a result of an imperfect assumption or relationship of the option with another underlying variable.

Traders use different Greek values to assess options risk and manage option portfolios. In other words, the price sensitivity of the option relative to the underlying.

Delta of a call option has a range between zero and one, while the delta of a put option has a range between zero and negative one. For example, assume an investor is long a call option with a delta of 0. Delta also represents the hedge ratio for creating a delta-neutral position for options traders.

So if you purchase a standard American call option with a 0. Net delta for a portfolio of options can also be used to obtain the portfolio's hedge ratio.

A less common usage of an option's delta is the current probability that it will expire in-the-money. For instance, a 0. Theta Θ represents the rate of change between the option price and time, or time sensitivity - sometimes known as an option's time decay. Theta indicates the amount an option's price would decrease as the time to expiration decreases, all else equal.

For example, assume an investor is long an option with a theta of The option's price would decrease by 50 cents every day that passes, all else being equal.

Theta increases when options are at-the-money, and decreases when options are in- and out-of-the money. Options closer to expiration also have accelerating time decay. Long calls and long puts usually have negative Theta. Short calls and short puts, on the other hand, have positive Theta. By comparison, an instrument whose value is not eroded by time, such as a stock, has zero Theta.

Gamma Γ represents the rate of change between an option's delta and the underlying asset's price. This is called second-order second-derivative price sensitivity. Let's assume an investor is long one call option on hypothetical stock XYZ. The call option has a delta of 0. Gamma is used to determine the stability of an option's delta. Higher gamma values indicate that delta could change dramatically in response to even small movements in the underlying's price.

Gamma is higher for options that are at-the-money and lower for options that are in- and out-of-the-money, and accelerates in magnitude as expiration approaches. Gamma values are generally smaller the further away from the date of expiration. This means that options with longer expirations are less sensitive to delta changes.

As expiration approaches, gamma values are typically larger, as price changes have more impact on gamma. Options traders may opt to not only hedge delta but also gamma in order to be delta-gamma neutral , meaning that as the underlying price moves, the delta will remain close to zero. Vega V represents the rate of change between an option's value and the underlying asset's implied volatility. This is the option's sensitivity to volatility.

For example, an option with a Vega of 0. Because increased volatility implies that the underlying instrument is more likely to experience extreme values , a rise in volatility correspondingly increases the value of an option. Conversely, a decrease in volatility negatively affects the value of the option.

Vega is at its maximum for at-the-money options that have longer times until expiration. Those familiar with the Greek language will point out that there is no actual Greek letter named vega. There are various theories about how this symbol, which resembles the Greek letter nu, found its way into stock-trading lingo.

This measures sensitivity to the interest rate. For example, assume a call option has a rho of 0. The opposite is true for put options. Rho is greatest for at-the-money options with long times until expiration. Some other Greeks, which aren't discussed as often, are lambda , epsilon, vomma , vera, speed, zomma , color, ultima. These Greeks are second- or third-derivatives of the pricing model and affect things like the change in delta with a change in volatility.

They are increasingly used in options trading strategies as computer software can quickly compute and account for these complex and sometimes esoteric risk factors. As mentioned earlier, call options allow the holder to buy an underlying security at the stated strike price by the expiration date called the expiry. The holder has no obligation to buy the asset if they do not want to purchase the asset. The risk to the buyer is limited to the premium paid. Fluctuations of the underlying stock have no impact.

Buyers are bullish on a stock and believe the share price will rise above the strike price before the option expires.

If the investor's bullish outlook is realized and the price increases above the strike price, the investor can exercise the option, buy the stock at the strike price, and immediately sell the stock at the current market price for a profit. Their profit on this trade is the market share price less the strike share price plus the expense of the option—the premium and any brokerage commission to place the orders.

The result is multiplied by the number of option contracts purchased, then multiplied by —assuming each contract represents shares. If the underlying stock price does not move above the strike price by the expiration date, the option expires worthlessly. The holder is not required to buy the shares but will lose the premium paid for the call.

Luke served as Head of ETF Sales at Cantor Fitzgerald. While in this seat, he began to notice the importance that institutional trading activity had on the movements and direction of stocks.

He spent years observing these activities and in his free time, with a partner, began designing quantitative models to look for unusual trading activity. He later moved to Jefferies, LLC as an SVP of Derivatives. There he published stock research based around the unusual activity signals he was developing. He later left Wall Street to work on this research full time at MAPsignals. Options for Beginners is an outstanding course that is well structured and easy to navigate.

I really valued the professional approach of Luke. I now feel confident to go out and do some basic options trades after taking this course. The course overall was well done and very informative. I feel more comfortable with options after taking the course and it will be an excellent source for reviewing option concepts. I intend to take some other courses soon! As someone looking for a new income path, Investopedia Academy was exactly what I was looking for.

Options for Beginners course and Become a Day Trader provided me a foundation of how to trade. The courses helped me understand the big picture of trading and the risks involved.

I needed an entry-level understanding of the markets, and this course provided me with the crisp and clear information I was after. In the real estate market, call options have long been used to assemble large parcels of land from separate owners; e. In the motion picture industry, film or theatrical producers often buy an option giving the right — but not the obligation — to dramatize a specific book or script.

Lines of credit give the potential borrower the right — but not the obligation — to borrow within a specified time period. Many choices, or embedded options, have traditionally been included in bond contracts. For example, many bonds are convertible into common stock at the buyer's option, or may be called bought back at specified prices at the issuer's option. Mortgage borrowers have long had the option to repay the loan early, which corresponds to a callable bond option.

Options contracts have been known for decades. The Chicago Board Options Exchange was established in , which set up a regime using standardized forms and terms and trade through a guaranteed clearing house. Trading activity and academic interest has increased since then. Today, many options are created in a standardized form and traded through clearing houses on regulated options exchanges , while other over-the-counter options are written as bilateral, customized contracts between a single buyer and seller, one or both of which may be a dealer or market-maker.

Options are part of a larger class of financial instruments known as derivative products , or simply, derivatives. A financial option is a contract between two counterparties with the terms of the option specified in a term sheet.

Option contracts may be quite complicated; however, at minimum, they usually contain the following specifications: [8]. Exchange-traded options also called "listed options" are a class of exchange-traded derivatives. Exchange-traded options have standardized contracts, and are settled through a clearing house with fulfillment guaranteed by the Options Clearing Corporation OCC.

Since the contracts are standardized, accurate pricing models are often available. Exchange-traded options include: [9] [10]. Over-the-counter options OTC options, also called "dealer options" are traded between two private parties, and are not listed on an exchange. The terms of an OTC option are unrestricted and may be individually tailored to meet any business need. In general, the option writer is a well-capitalized institution in order to prevent the credit risk.

Option types commonly traded over the counter include:. By avoiding an exchange, users of OTC options can narrowly tailor the terms of the option contract to suit individual business requirements. In addition, OTC option transactions generally do not need to be advertised to the market and face little or no regulatory requirements.

However, OTC counterparties must establish credit lines with each other, and conform to each other's clearing and settlement procedures. With few exceptions, [11] there are no secondary markets for employee stock options. These must either be exercised by the original grantee or allowed to expire.

The most common way to trade options is via standardized options contracts that are listed by various futures and options exchanges. By publishing continuous, live markets for option prices, an exchange enables independent parties to engage in price discovery and execute transactions.

As an intermediary to both sides of the transaction, the benefits the exchange provides to the transaction include:. These trades are described from the point of view of a speculator. If they are combined with other positions, they can also be used in hedging. An option contract in US markets usually represents shares of the underlying security. A trader who expects a stock's price to increase can buy a call option to purchase the stock at a fixed price strike price at a later date, rather than purchase the stock outright.

The cash outlay on the option is the premium. The trader would have no obligation to buy the stock, but only has the right to do so on or before the expiration date.

The risk of loss would be limited to the premium paid, unlike the possible loss had the stock been bought outright. The holder of an American-style call option can sell the option holding at any time until the expiration date, and would consider doing so when the stock's spot price is above the exercise price, especially if the holder expects the price of the option to drop.

By selling the option early in that situation, the trader can realise an immediate profit. Alternatively, the trader can exercise the option — for example, if there is no secondary market for the options — and then sell the stock, realising a profit.

A trader would make a profit if the spot price of the shares rises by more than the premium. For example, if the exercise price is and premium paid is 10, then if the spot price of rises to only the transaction is break-even; an increase in stock price above produces a profit. If the stock price at expiration is lower than the exercise price, the holder of the option at that time will let the call contract expire and lose only the premium or the price paid on transfer.

A trader who expects a stock's price to decrease can buy a put option to sell the stock at a fixed price strike price at a later date. The trader is under no obligation to sell the stock, but has the right to do so on or before the expiration date. If the stock price at expiration is below the exercise price by more than the premium paid, the trader makes a profit. If the stock price at expiration is above the exercise price, the trader lets the put contract expire, and loses only the premium paid.

In the transaction, the premium also plays a role as it enhances the break-even point. For example, if the exercise price is and the premium paid is 10, then a spot price between 90 and is not profitable. The trader makes a profit only if the spot price is below The trader exercising a put option on a stock does not need to own the underlying asset, because most stocks can be shorted.

A trader who expects a stock's price to decrease can sell the stock short or instead sell, or "write", a call. The trader selling a call has an obligation to sell the stock to the call buyer at a fixed price "strike price". If the seller does not own the stock when the option is exercised, they are obligated to purchase the stock in the market at the prevailing market price.

If the stock price decreases, the seller of the call call writer makes a profit in the amount of the premium. If the stock price increases over the strike price by more than the amount of the premium, the seller loses money, with the potential loss being unlimited. A trader who expects a stock's price to increase can buy the stock or instead sell, or "write", a put. The trader selling a put has an obligation to buy the stock from the put buyer at a fixed price "strike price".

If the stock price at expiration is above the strike price, the seller of the put put writer makes a profit in the amount of the premium. If the stock price at expiration is below the strike price by more than the amount of the premium, the trader loses money, with the potential loss being up to the strike price minus the premium. Combining any of the four basic kinds of option trades possibly with different exercise prices and maturities and the two basic kinds of stock trades long and short allows a variety of options strategies.

Simple strategies usually combine only a few trades, while more complicated strategies can combine several. Strategies are often used to engineer a particular risk profile to movements in the underlying security.

For example, buying a butterfly spread long one X1 call, short two X2 calls, and long one X3 call allows a trader to profit if the stock price on the expiration date is near the middle exercise price, X2, and does not expose the trader to a large loss. A condor is a strategy that is similar to a butterfly spread, but with different strikes for the short options — offering a larger likelihood of profit but with a lower net credit compared to the butterfly spread.

Selling a straddle selling both a put and a call at the same exercise price would give a trader a greater profit than a butterfly if the final stock price is near the exercise price, but might result in a large loss.

Similar to the straddle is the strangle which is also constructed by a call and a put, but whose strikes are different, reducing the net debit of the trade, but also reducing the risk of loss in the trade. One well-known strategy is the covered call , in which a trader buys a stock or holds a previously-purchased long stock position , and sells a call. This can be contrasted with a naked call. See also naked put. If the stock price rises above the exercise price, the call will be exercised and the trader will get a fixed profit.

If the stock price falls, the call will not be exercised, and any loss incurred to the trader will be partially offset by the premium received from selling the call. Overall, the payoffs match the payoffs from selling a put. This relationship is known as put—call parity and offers insights for financial theory. Another very common strategy is the protective put , in which a trader buys a stock or holds a previously-purchased long stock position , and buys a put.

This strategy acts as an insurance when investing on the underlying stock, hedging the investor's potential losses, but also shrinking an otherwise larger profit, if just purchasing the stock without the put. The maximum profit of a protective put is theoretically unlimited as the strategy involves being long on the underlying stock.

The maximum loss is limited to the purchase price of the underlying stock less the strike price of the put option and the premium paid. A protective put is also known as a married put. Another important class of options, particularly in the U. Other types of options exist in many financial contracts, for example real estate options are often used to assemble large parcels of land, and prepayment options are usually included in mortgage loans.

However, many of the valuation and risk management principles apply across all financial options. Because the values of option contracts depend on a number of different variables in addition to the value of the underlying asset, they are complex to value. There are many pricing models in use, although all essentially incorporate the concepts of rational pricing i.

risk neutrality , moneyness , option time value , and put—call parity. The valuation itself combines a model of the behavior "process" of the underlying price with a mathematical method which returns the premium as a function of the assumed behavior. The models range from the prototypical Black—Scholes model for equities, [16] [ unreliable source?

The term option refers to a financial instrument that is based on the value of underlying securities such as stocks. An options contract offers the buyer the opportunity to buy or sell—depending on the type of contract they hold—the underlying asset.

Unlike futures , the holder is not required to buy or sell the asset if they decide against it. Each options contract will have a specific expiration date by which the holder must exercise their option. The stated price on an option is known as the strike price. Options are typically bought and sold through online or retail brokers. Options are versatile financial products. These contracts involve a buyer and seller, where the buyer pays a premium for the rights granted by the contract.

Call options allow the holder to buy the asset at a stated price within a specific timeframe. Put options , on the other hand, allow the holder to sell the asset at a stated price within a specific timeframe.

Each call option has a bullish buyer and a bearish seller while put options have a bearish buyer and a bullish seller. Traders and investors buy and sell options for several reasons. Options speculation allows a trader to hold a leveraged position in an asset at a lower cost than buying shares of the asset. Investors use options to hedge or reduce the risk exposure of their portfolios.

In some cases, the option holder can generate income when they buy call options or become an options writer. Options are also one of the most direct ways to invest in oil. For options traders , an option's daily trading volume and open interest are the two key numbers to watch in order to make the most well-informed investment decisions. American options can be exercised any time before the expiration date of the option, while European options can only be exercised on the expiration date or the exercise date.

Exercising means utilizing the right to buy or sell the underlying security. A call option gives the holder the right, but not the obligation, to buy the underlying security at the strike price on or before expiration.

A call option will therefore become more valuable as the underlying security rises in price calls have a positive delta. A long call can be used to speculate on the price of the underlying rising, since it has unlimited upside potential but the maximum loss is the premium price paid for the option. Opposite to call options, a put gives the holder the right, but not the obligation, to instead sell the underlying stock at the strike price on or before expiration.

A long put, therefore, is a short position in the underlying security, since the put gains value as the underlying's price falls they have a negative delta. Protective puts can be purchased as a sort of insurance, providing a price floor for investors to hedge their positions.
