By rearranging put-call parity:

• Floor = Stock + Put

• Write a covered put = – Stock – Put • Cap = Call – Stock

• Write a covered call = – Call + Stock

Synthetic Forward

Syn. Long forw. = Long call (K ) + Short put (K ) Syn. Short forw. = Short call (K ) + Long put (K )

Bull Spread

• Long call (K 1) + Short call (K 2),K 1 <K 2

forward (K 2),K 1 <K 2

Ratio Spread

Long and short an unequal number of calls/puts with different strike prices

Collar

Long put (K 1) + Short call (K 2),K 1 <K 2

Collared Stock
