Tips & Tactics

Helpful advice for making the most of this Guide

• •  You should understand all of the risks involved before spending hard-earned assets on any financial vehicle. While the Garman-Kohlhagen option pricing model helps alleviate some of this risk in currency option trading, there is still significant risk to your investment.

The Garman-Kohlhagen model is specific to the foreign currency option market. This option market doesn't price its financial vehicles in conventional terms; it states them in terms of implied volatility and then uses Garman-Kohlhagen to determine a price. The Garman-Kohlhagen calculates the fair value of currency option, and in an efficient market fair value will usually equal market value. Being able to understand the Garman-Kohlhagen option pricing key terms will establish a knowledge base to help you understand the more complicated aspect of this formula. Before you start to research, the definitions and context of these key terms are as follows:

FX option

The term FX option represents an abbreviation for a foreign exchange option contract. The buyer of these options contract has the right but not the obligation to exercise the option. The owner will exercise the right when it's to his or her benefit. The Garman-Kohlhagen model is a primary method to price these options, more specifically, for the currency options on foreign exchanges.

I recommend: Review the explanation of currency option or FX options at Oz Forex.

Lognormal distribution

In the Garman-Kohlhagen model, one of the main assumptions is that the option returns follow a lognormal distribution. A lognormal distribution is a solo-tailed probability distribution where the random variable in a model is normally distributed. The lognormal distribution assumption assumes that returns will fall within a normal distribution within the Garman-Kohlhagen option pricing model.

I recommend: Study the definition and examples of a lognormal distribution available at the Risk Glossary.

Fair value

Fair value is the expected result of the Garman-Kohlhagen options pricing model. Fair value is the closest approximation for market value of foreign currency options. The Garman-Kohlhagen uses a complicated formula to convert implied volatility into fair-value pricing.

I recommend: Review the fair-value pricing article offered at the Financial Analysts Journal.

Risk-free interest rate

The risk-free interest rate is in theory the highest return you can attain on investment with zero risk. The Garman-Kohlhagen model assumes that the risk-free interest rate is a known entity throughout the life of the options contract.

I recommend: Examine the risk-free rate explanation available at Investopedia to understand the model assumption. For a full list of the Garman-Kohlhagen assumption, review the information at Montego Data Limited.

Implied volatility

Implied volatility is the initial listing vehicle for foreign currency options. The Garman-Kohlhagen then converts the implied volatility into fair-value pricing.

I recommend: Evaluate the implied volatility tutorial from My Stock Market Power.

Put and call options

A put option is the right, not the obligation, to sell an option, in this case a foreign currency option. Conversely, a call option is the right, but not the obligation, to buy a foreign exchange option. The Garman-Kohlhagen option pricing model has a separate formula for each type of option.

I recommend: Assess the definition of a put and call option from CIBC World Markets.

The Garman-Kohlhagen option formula is a variation on the Black Scholes model but it denotes foreign and domestic interest rates as separate terms. The primary use for the Garman-Kohlhagen pricing model is for put and calls foreign currency options. However, you can use this formula for dynamic hedging of your currency risks. While the Garman-Kohlhagen option pricing model applications and uses are narrow in scope, learning those uses are not.

The Garman-Kohlhagen options put formula differs slightly from the one for a foreign currency call options. When using this formula you must assume that transaction costs and taxes are zero, the distribution of the currency exchange rate is lognormal, arbitrage isn't a possibility, the foreign rates, risk-free rates and currency exchange rate volatility are known over the life of the option and there are no penalties for short sales. Once you make these assumptions, then you can use the Garman-Kohlhagen option valuation model for the following:

1. Use the Garman-Kohlhagen option pricing model information to price a foreign currency call option.

2. Calculate the price of foreign currency put option with the Garman-Kohlhagen option model.

3. Utilize the Garman-Kohlhagen pricing formula for dynamic hedging.

To price a call option you'll need to obtain the inputs for all of the above variables.

I recommend: Examine the trading glossary explanation of a put option. Employ the foreign currency put option formula available at the Risk Glossary.

Apply the Garman-Kohlhagen option formula in a dynamic hedging strategy

Dynamic hedging is when you use an underlying security to limit the risk of the primary security. For instance, in derivatives trading you can price a foreign currency option with the formula, then purchase a short option to offset the risk by purchasing a linear position in the same currency.
