We also provide the derivations of Greek letters for call and put options on both dividends-paying stock and non-dividends stock. Then we discuss some applications of Greek letters. Finally, we show the relationship between Greek letters, one of the examples can be seen from the Black-Scholes partial differential equation. Key words Greek letters, Delta, Theta, Gamma, Vega, Rho, Black-Scholes option pricing model, Black-Scholes partial differential equation 30.1 Introduction Greek letters are defined as the sensitivities of the option price to a single-unit change in the value of either a state variable or a parameter. Such sensitivities can represent the different dimensions to the risk in an option. Financial institutions who sell option to their clients can manage their risk by Greek letters analysis. In this chapter, we will discuss the definitions and derivations of Greek letters. We also specifically derive Greek letters for call (put) options on non-dividend stock and dividends-paying stock. Some examples are provided to explain the application of Greek letters. Finally, we will describe the relationship between Greek letters and the implication in delta neutral portfolio. 30.2 Delta ( EMBED Equation.DSMT4 ) The delta of an option,  EMBED Equation.DSMT4 , is defined as the rate of change of the option price respected to the rate of change of underlying asset price:  EMBED Equation.DSMT4  where  EMBED Equation.DSMT4  is the option price and S is underlying asset price. We next show the derivation of delta for various kinds of stock option. 30.2.1 Derivation of Delta for Different Kinds of Stock Options From Black-Scholes option pricing model, we know the price of call option on a non-dividend stock can be written as:  EMBED Equation.3  (30.1) and the price of put option on a non-dividend stock can be written as:  EMBED Equation.3  (30.2) where  EMBED Equation.3   EMBED Equation.3   EMBED Equation.3   EMBED Equation.3  is the cumulative density function of normal distribution.  EMBED Equation.3  First, we calculate  EMBED Equation.3  (30.3)  EMBED Equation.3  (30.4) Eq. (30.2) and Eq. (30.3) will be used repetitively in determining following Greek letters when the underlying asset is a non-dividend paying stock. For a European call option on a non-dividend stock, delta can be shown as  EMBED Equation.DSMT4  (30.5) The derivation of Eq. (30.5) is in the following:  EMBED Equation.3  For a European put option on a non-dividend stock, delta can be shown as  EMBED Equation.DSMT4  (30.6) The derivation of Eq. (30.6) is  EMBED Equation.3  If the underlying asset is a dividend-paying stock providing a dividend yield at rate q, Black-Scholes formulas for the prices of a European call option on a dividend-paying stock and a European put option on a dividend-paying stock are  EMBED Equation.3  (30.7) and  EMBED Equation.3  (30.8) where  EMBED Equation.3   EMBED Equation.3  To make the following derivations more easily, we calculate Eq. (30.9) and Eq. (30.10) in advance.  EMBED Equation.3  (30.9)  EMBED Equation.3  (30.10) For a European call option on a dividend-paying stock, delta can be shown as  EMBED Equation.DSMT4  (30.11) The derivation of (30.11) is  EMBED Equation.3  For a European call option on a dividend-paying stock, delta can be shown as  EMBED Equation.DSMT4  (30.12) The derivation of (30.12) is  EMBED Equation.3  30.2.2 Application of Delta Figure 30.1 shows the relationship between the price of a call option and the price of its underlying asset. The delta of this call option is the slope of the line at the point of A corresponding to current price of the underlying asset.  Figure 30.1 By calculating delta ratio, a financial institution that sells option to a client can make a delta neutral position to hedge the risk of changes of the underlying asset price. Suppose that the current stock price is $100, the call option price on stock is $10, and the current delta of the call option is 0.4. A financial institution sold 10 call option to its client, so that the client has right to buy 1,000 shares at time to maturity. To construct a delta hedge position, the financial institution should buy 0.4 x 1,000 = 400 shares of stock. If the stock price goes up to $1, the option price will go up by $0.4. In this situation, the financial institution has a $400 ($1 x 400 shares) gain in its stock position, and a $400 ($0.4 x 1,000 shares) loss in its option position. The total payoff of the financial institution is zero. On the other hand, if the stock price goes down by $1, the option price will go down by $0.4. The total payoff of the financial institution is also zero. However, the relationship between option price and stock price is not linear, so delta changes over different stock price. If an investor wants to remain his portfolio in delta neutral, he should adjust his hedged ratio periodically. The more frequently adjustment he does, the better delta-hedging he gets. Figure 30.2 exhibits the change in delta affects the delta-hedges. If the underlying stock has a price equal to $20, then the investor who uses only delta as risk measure will consider that his portfolio has no risk. However, as the underlying stock prices changes, either up or down, the delta changes as well and thus he will have to use different delta hedging. Delta measure can be combined with other risk measures to yield better risk measurement. We will discuss it further in the following sections.  Figure 30.2 30.3 Theta ( EMBED Equation.DSMT4 ) The theta of an option,  EMBED Equation.DSMT4 , is defined as the rate of change of the option price respected to the passage of time:  EMBED Equation.DSMT4  where  EMBED Equation.DSMT4  is the option price and  EMBED Equation.DSMT4  is the passage of time. If  EMBED Equation.DSMT4 , theta ( EMBED Equation.DSMT4 ) can also be defined as minus one timing the rate of change of the option price respected to time to maturity. The derivation of such transformation is easy and straight forward:  EMBED Equation.DSMT4  where  EMBED Equation.DSMT4  is time to maturity. For the derivation of theta for various kinds of stock option, we use the definition of negative differential on time to maturity. 30.3.1 Derivation of Theta for Different Kinds of Stock Option For a European call option on a non-dividend stock, theta can be written as:  EMBED Equation.DSMT4  (30.13) The derivation of (30.13) is  EMBED Equation.3  For a European put option on a non-dividend stock, theta can be shown as  EMBED Equation.DSMT4  (30.14) The derivation of (30.14) is  EMBED Equation.3  For a European call option on a dividend-paying stock, theta can be shown as  EMBED Equation.DSMT4  (30.15) The derivation of (30.15) is  EMBED Equation.3  For a European call option on a dividend-paying stock, theta can be shown as  EMBED Equation.DSMT4  (30.16) The derivation of (30.16) is  EMBED Equation.3  30.3.2 Application of Theta ( EMBED Equation.DSMT4 ) The value of option is the combination of time value and stock value. When time passes, the time value of the option decreases. Thus, the rate of change of the option price with respective to the passage of time, theta, is usually negative. Because the passage of time on an option is not uncertain, we do not need to make a theta hedge portfolio against the effect of the passage of time. However, we still regard theta as a useful parameter, because it is a proxy of gamma in the delta neutral portfolio. For the specific detail, we will discuss in the following sections. 30.4 Gamma ( EMBED Equation.DSMT4 ) The gamma of an option,  EMBED Equation.DSMT4 , is defined as the rate of change of delta respected to the rate of change of underlying asset price::  EMBED Equation.DSMT4  where  EMBED Equation.DSMT4  is the option price and S is the underlying asset price. Because the option is not linearly dependent on its underlying asset, delta-neutral hedge strategy is useful only when the movement of underlying asset price is small. Once the underlying asset price moves wider, gamma-neutral hedge is necessary. We next show the derivation of gamma for various kinds of stock option. 30.4.1 Derivation of Gamma for Different Kinds of Stock Option For a European call option on a non-dividend stock, gamma can be shown as  EMBED Equation.DSMT4  (30.17) The derivation of (30.17) is  EMBED Equation.3  For a European put option on a non-dividend stock, gamma can be shown as  EMBED Equation.DSMT4  (30.18) The derivation of (30.18) is  EMBED Equation.3  For a European call option on a dividend-paying stock, gamma can be shown as  EMBED Equation.DSMT4  (30.19) The derivation of (30.19) is  EMBED Equation.3  For a European call option on a dividend-paying stock, gamma can be shown as  EMBED Equation.DSMT4  (30.20) The derivation of (30.20) is  EMBED Equation.3  30.4.2 Application of Gamma ( EMBED Equation.DSMT4 ) One can use delta and gamma together to calculate the changes of the option due to changes in the underlying stock price. This change can be approximated by the following relations.  EMBED Equation.DSMT4  From the above relation, one can observe that the gamma makes the correction for the fact that the option value is not a linear function of underlying stock price. This approximation comes from the Taylor series expansion near the initial stock price. If we let V be option value, S be stock price, and S0 be initial stock price, then the Taylor series expansion around S0 yields the following.  EMBED Equation.DSMT4  If we only consider the first three terms, the approximation is then,  EMBED Equation.DSMT4 . For example, if a portfolio of options has a delta equal to $10000 and a gamma equal to $5000, the change in the portfolio value if the stock price drop to $34 from $35 is approximately,  EMBED Equation.DSMT4  The above analysis can also be applied to measure the price sensitivity of interest rate related assets or portfolio to interest rate changes. Here we introduce Modified Duration and Convexity as risk measure corresponding to the above delta and gamma. Modified duration measures the percentage change in asset or portfolio value resulting from a percentage change in interest rate.  EMBED Equation.DSMT4  Using the modified duration,  EMBED Equation.DSMT4  we can calculate the value changes of the portfolio. The above relation corresponds to the previous discussion of delta measure. We want to know how the price of the portfolio changes given a change in interest rate. Similar to delta, modified duration only show the first order approximation of the changes in value. In order to account for the nonlinear relation between the interest rate and portfolio value, we need a second order approximation similar to the gamma measure before, this is then the convexity measure. Convexity is the interest rate gamma divided by price,  EMBED Equation.DSMT4  and this measure captures the nonlinear part of the price changes due to interest rate changes. Using the modified duration and convexity together allow us to develop first as well as second order approximation of the price changes similar to previous discussion.  EMBED Equation.DSMT4  As a result, (-duration x P) and (convexity x P) act like the delta and gamma measure respectively in the previous discussion. This shows that these Greeks can also be applied in measuring risk in interest rate related assets or portfolio. Next we discuss how to make a portfolio gamma neutral. Suppose the gamma of a delta-neutral portfolio is  EMBED Equation.DSMT4 , the gamma of the option in this portfolio is  EMBED Equation.DSMT4 , and  EMBED Equation.DSMT4  is the number of options added to the delta-neutral portfolio. Then, the gamma of this new portfolio is  EMBED Equation.DSMT4  To make a gamma-neutral portfolio, we should trade  EMBED Equation.DSMT4  options. Because the position of option changes, the new portfolio is not in the delta-neutral. We should change the position of the underlying asset to maintain delta-neutral. For example, the delta and gamma of a particular call option are 0.7 and 1.2. A delta-neutral portfolio has a gamma of -2,400. To make a delta-neutral and gamma-neutral portfolio, we should add a long position of 2,400/1.2=2,000 shares and a short position of 2,000 x 0.7=1,400 shares in the original portfolio. 30.5 Vega ( EMBED Equation.DSMT4 ) The vega of an option,  EMBED Equation.DSMT4 , is defined as the rate of change of the option price respected to the volatility of the underlying asset:  EMBED Equation.DSMT4  where  EMBED Equation.DSMT4  is the option price and  EMBED Equation.DSMT4  is volatility of the stock price. We next show the derivation of vega for various kinds of stock option. 30.5.1 Derivation of Vega for Different Kinds of Stock Option For a European call option on a non-dividend stock, vega can be shown as  EMBED Equation.DSMT4  (30.21) The derivation of (30.21) is  EMBED Equation.3  For a European put option on a non-dividend stock, vega can be shown as  EMBED Equation.DSMT4  (30.22) The derivation of (30.22) is  EMBED Equation.3  For a European call option on a dividend-paying stock, vega can be shown as  EMBED Equation.DSMT4  (30.23) The derivation of (30.23) is  EMBED Equation.3  For a European call option on a dividend-paying stock, vega can be shown as  EMBED Equation.DSMT4  (30.24) The derivation of (30.24) is  EMBED Equation.3  30.5.2 Application of Vega ( EMBED Equation.DSMT4 ) Suppose a delta-neutral and gamma-neutral portfolio has a vega equal to  EMBED Equation.DSMT4  and the vega of a particular option is  EMBED Equation.DSMT4 . Similar to gamma, we can add a position of  EMBED Equation.DSMT4  in option to make a vega-neutral portfolio. To maintain delta-neutral, we should change the underlying asset position. However, when we change the option position, the new portfolio is not gamma-neutral. Generally, a portfolio with one option cannot maintain its gamma-neutral and vega-neutral at the same time. If we want a portfolio to be both gamma-neutral and vega-neutral, we should include at least two kind of option on the same underlying asset in our portfolio. For example, a delta-neutral and gamma-neutral portfolio contains option A, option B, and underlying asset. The gamma and vega of this portfolio are -3,200 and -2,500, respectively. Option A has a delta of 0.3, gamma of 1.2, and vega of 1.5. Option B has a delta of 0.4, gamma of 1.6 and vega of 0.8. The new portfolio will be both gamma-neutral and vega-neutral when adding  EMBED Equation.DSMT4  of option A and  EMBED Equation.DSMT4  of option B into the original portfolio.  EMBED Equation.DSMT4   EMBED Equation.DSMT4  From two equations shown above, we can get the solution that  EMBED Equation.DSMT4 =1000 and  EMBED Equation.DSMT4 = 1250. The delta of new portfolio is 1000 x .3 + 1250 x 0.4 = 800. To maintain delta-neutral, we need to short 800 shares of the underlying asset. 30.6 Rho ( EMBED Equation.DSMT4 ) The rho of an option is defined as the rate of change of the option price respected to the interest rate:  EMBED Equation.DSMT4  where  EMBED Equation.DSMT4  is the option price and r is interest rate. The rho for an ordinary stock call option should be positive because higher interest rate reduces the present value of the strike price which in turn increases the value of the call option. Similarly, the rho of an ordinary put option should be negative by the same reasoning. We next show the derivation of rho for various kinds of stock option. 30.6.1 Derivation of Rho for Different Kinds of stock option For a European call option on a non-dividend stock, rho can be shown as  EMBED Equation.DSMT4  (30.25) The derivation of (30.25) is  EMBED Equation.3  For a European put option on a non-dividend stock, rho can be shown as  EMBED Equation.DSMT4  (30.26) The derivation of (30.26) is  EMBED Equation.3  For a European call option on a dividend-paying stock, rho can be shown as  EMBED Equation.DSMT4  (30.27) The derivation of (30.27) is  EMBED Equation.3  For a European put option on a dividend-paying stock, rho can be shown as  EMBED Equation.DSMT4  (30.28) The derivation of (30.28) is  EMBED Equation.3  30.6.2 Application of Rho ( EMBED Equation.DSMT4 ) Assume that an investor would like to see how interest rate changes affect the value of a 3-month European put option she holds with the following information. The current stock price is $65 and the strike price is $58. The interest rate and the volatility of the stock is 5% and 30% per annum respectively. The rho of this European put can be calculated as following.  EMBED Equation.DSMT4  This calculation indicates that given 1% change increase in interest rate, say from 5% to 6%, the value of this European call option will decrease 0.03168 (0.01 x 3.168). This simple example can be further applied to stocks that pay dividends using the derivation results shown previously. 30.7 Derivation of Sensitivity for Stock Options Respective with Exercise Price For a European call option on a non-dividend stock, the sensitivity can be shown as  EMBED Equation.3  (30.29) The derivation of (30.29) is  EMBED Equation.3  For a European put option on a non-dividend stock, the sensitivity can be shown as  EMBED Equation.3  (30.30) The derivation of (30.30) is  EMBED Equation.3  For a European call option on a dividend-paying stock, the sensitivity can be shown as  EMBED Equation.3  (30.31) The derivation of (30.31) is  EMBED Equation.3  For a European put option on a dividend-paying stock, the sensitivity can be shown as  EMBED Equation.3  (30.32) The derivation of (30.32) is  EMBED Equation.3  30.8 Relationship between Delta, Theta, and Gamma So far, the discussion has introduced the derivation and application of each individual Greeks and how they can be applied in portfolio management. In practice, the interaction or trade-off between these parameters is of concern as well. For example, recall the partial differential equation for the Black-Scholes formula with non-dividend paying stock can be written as  EMBED Equation.DSMT4  Where  EMBED Equation.DSMT4  is the value of the derivative security contingent on stock price, S is the price of stock, r is the risk free rate, and EMBED Equation.DSMT4  is the volatility of the stock price, and t is the time to expiration of the derivative. Given the earlier derivation, we can rewrite the Black-Scholes PDE as  EMBED Equation.DSMT4  This relation gives us the trade-off between delta, gamma, and theta. For example, suppose there are two delta neutral  EMBED Equation.DSMT4  portfolios, one with positive gamma  EMBED Equation.DSMT4 and the other one with negative gamma EMBED Equation.DSMT4  and they both have value of $1  EMBED Equation.DSMT4 . The trade-off can be written as  EMBED Equation.DSMT4  For the first portfolio, if gamma is positive and large, then theta is negative and large. When gamma is positive, change in stock prices result in higher value of the option. This means that when there is no change in stock prices, the value of the option declines as we approach the expiration date. As a result, the theta is negative. On the other hand, when gamma is negative and large, change in stock prices result in lower option value. This means that when there is no stock price changes, the value of the option increases as we approach the expiration and theta is positive. This gives us a trade-off between gamma and theta and they can be used as proxy for each other in a delta neutral portfolio. 30.9 Conclusion In this chapter we have shown the derivation of the sensitivities of the option price to the change in the value of state variables or parameters. The first Greek is delta ( EMBED Equation.DSMT4 ) which is the rate of change of option price to change in price of underlying asset. Once the delta is calculated, the next step is the rate of change of delta with respect to underlying asset price which gives us gamma ( EMBED Equation.DSMT4 ). Another two risk measures are theta ( EMBED Equation.DSMT4 ) and rho ( EMBED Equation.DSMT4 ), they measure the change in option value with respect to passing time and interest rate respectively. Finally, one can also measure the change in option value with respect to the volatility of the underlying asset and this gives us the vega ( EMBED Equation.DSMT4 ). The relationship between these risk measures are shown, one of the example can be seen from the Black-Scholes partial differential equation. Furthermore, the applications of these Greeks letter in the portfolio management have also been discussed. Risk management is one of the important topics in finance today, both for academics and practitioners. Given the recent credit crisis, one can observe that it is crucial to properly measure the risk related to the ever more complicated financial assets.
