Alastair [stock price] + Max{0,[excercise price - stock }price] - Max{0,[stock price - exercise price} = S + 0 - S + X = X Or S + X - S + 0 = X
antarctica put-call parity: S+P-C = X/(1+R)^T
=> final date: X
Rotigga Buy underlying stock + Long put + Short call
Suppose that Exercise price is at \$105

Scenario 1: Underlying Stock < Exercise Price
Suppose underlying stock is worth \$100 on the final exercise date
Value: Underlying stock + Long put + Short call
Value = \$100 + \$5 + \$0 = \$105 = Exercise Price

Scenario 2: Underlying Stock > Exercise Price
Suppose underlying stock is worth \$110 on the final exercise date
Value: Underlying stock + Long put + Short call
Value = \$110 + 0 + (-\$5) = \$105 = Exercise Price
frankannor This is put-call parity at maturity
mchu c0 + X/(1 + r)T = p0 + S0. Thus, at day 0, p0 + S0 - c0 = X/(1 + r)T at expiration=X
harpalani Thanks Rotigga! Crystal clear!
gill15 Seriously...that was crystal clear....guys make it simple

P + S - C = X / (1 + R)

what is the right side --- THE BOND --- BUY a BOND

The right side the Bonds value will be X regardless of what happens....
bbadger When thinking about synthetics, think about the call. If you buy a call, sell a put you're long the synthetic. Sell a call, buy a put = short the synthetic.
Shaan23 Gill you're awesome
