Chance/BrooksAn Introduction to Derivatives and Risk Management, 9th ed.Ch. 7: 11 Money Spreads (continued) n Collars (continued) F See Figure 7.5 for DCRB July 120/136.165, P 1 = $13.65, C 2 = $13.65. That is, a call strike of 136.165 generates the same premium as a put with strike of 120. This result can be obtained only by using an option pricing model and plugging in exercise prices until you find the one that makes the call premium the same as the put premium. Figure 7.5Figure 7.5 F This will nearly always require the use of OTC options. F Maximum profit = X 2 - S 0. Minimum = X 1 - S 0. F Breakeven: S T * = S 0. © 2010 Cengage Learning.

Chance/BrooksAn Introduction to Derivatives and Risk Management, 9th ed.Ch. 7: 12 Money Spreads (continued) n Collars (continued) u The collar is a lot like a bull spread (compare Figure 7.5 to Figure 7.1). Figure 7.5Figure 7.1Figure 7.5Figure 7.1 F The collar payoff exceeds the bull spread payoff by the difference between X 1 and the interest on X 1. F Thus, the collar is equivalent to a bull spread plus a risk-free bond paying X 1 at expiration. u For different holding periods, compute profit for range of stock prices at T 1, T 2, and T using Black-Scholes- Merton model.

Chance/BrooksAn Introduction to Derivatives and Risk Management, 9th ed.Ch. 7: 15 Calendar Spreads u Buy call with longer time to expiration, sell call with shorter time to expiration. u Note how this strategy cannot be held to expiration because there are two different expirations. u Profitability depends on volatility and time value decay. u Use Black-Scholes-Merton model to value options at end of holding period if prior to expiration. u See Figure 7.9. Figure 7.9Figure 7.9 u Note time value decay. See Table 7.2 and Figure 7.10. Table 7.2Figure 7.10Table 7.2Figure 7.10 u Early exercise can be problem. u Can be constructed with puts as well. © 2010 Cengage Learning. All Rights Reserved.

Chance/BrooksAn Introduction to Derivatives and Risk Management, 9th ed.Ch. 7: 16 Ratio Spreads u Long one option, short another based on deltas of two options. Designed to be delta-neutral. Can use any two options on same stock. u Portfolio value F V = N 1 C 1 + N 2 C 2  Set to zero and solve for N 1 /N 2 = - 2 / 1, which is ratio of their deltas (recall that  Set to zero and solve for N 1 /N 2 = -  2 /  1, which is ratio of their deltas (recall that  = N(d 1 ) from Black-Scholes-Merton model). u Buy June 120s, sell June 125s. Delta of 120 is 0.630; delta of 125 is 0.569. Ratio is –(0.569/0.630) = -0.903. For example, buy 903 June 120s, sell 1,000 June 125s u Note why this works and that delta will change. u Why do this?
