The Theory of Interest - Solutions Manual Chapter 13 6. ( a ) The shorter-term option should sell for a lower price than the longer-term option. Thus, sell one $5 option and buy one $4 option. Adjust position in 6 months. ( b ) If 50 S in 6 months, profit is: $1 if 48 S = in one year. $1 if 50 S = in one year. $3 if 52 S = in one year. If 50 S is 6 months, profit is: $3 if 48 S = in one year. $1 if 50 S = in one year. $1 if 52 S = in one year. 7. See answers to the Exercises on p. 623. 8. P increases as S decreases, the opposite of calls. P increases as E increases, the opposite of calls. P increases at t increases, since longer-term options are more valuable than shorter- term options.
