Introduction
• Put-call parity: replication of positions in the underlying.
• Allow for very flexible types of payoffs (portfolios of options).
• Risk management:– Hedging risks.– Portfolio insurance: Stock + Put.

Relationship with Underlying
• Remember the put-call parity:
P + S = C + PV(X)
• PV (X) is independent of underlying.
• Long Stock + Long Put ~ Call.
• Short Stock + Short Put ~ Short Call.
• Short Stock + Long Call ~ Long Put.
• Long Stock + Short Call ~ Short Put.

Bull Spread with Calls (Example)
• Prices of securities:– S = 47.
– C(X=45) = 3.
– C(X=50) = 0.54.
• Buy a call with strike price 45 and write a call with strike price 50. Cost: 3-0.54 = 2.46.
• When S is lower than 45, both calls are out of the money and we lose the investment in the portfolio.
• When S is above 45, but below 50, only the call we bought is in the money. Net payoff:
S - 45 - 2.46 = S - 47.46

Bull Spread (Example, cont.)
• When the stock price is above 50, both options are in the money. The net payoff is,
S – 45 – (S – 50) – 2.46 = 2.54• In summary,
Net Payoff S < 45 -2.46
45 < S < 50 S - 47.46 50 < S 2.54
• And the break-even point is S = 47.46
