Practical form of put call parity and why it comes in handy
Published by The Retail Trader · AUG 07, 2026 · Derivatives (F&O)
By combining options, a position can be created that behaves almost like futures. This is called synthetic position, and there is a simple relationship behind it.
Buying a call and selling a put of the same strike together gives a payoff almost like long futures. Like short futures on reverse.
This relationship is called put call parity. He tells that the values of call, put and underlying are tied together – all three are not free.
It is often used mechanically:
• Sometimes liquidity in options is better than futures.
• Margin calculation can be different in both the methods.
• It is useful in changing the direction without closing a position.
• Showing a door price well above parity is often a sign of liquidity, not free money.
Synthetic positions look like "hidden arbitrage" but they are just a different way of taking the same risk. Its payoff is like futures, which means its loss is also like futures.
