Synthetic Positions

What you must believe

No market view at all: this card is the grammar of the toolbox. Call, put and future are three spellings of the same exposures, and every position can be rebuilt from the other two.

Construction

Synthetic long future: buy the 25,000 CE at ₹120 and sell the 25,000 PE at ₹110. Net debit ₹10; the position behaves exactly like NIFTY bought at 25,010, one straight line.

The numbers, before entry

• Behaviour: one-for-one with NIFTY, up and down, no curvature
• Breakeven: 25,010
• Margin: the short put prices near naked; this is not a capital saving for retail
• The equation: long call + short put = long future, at any single strike, rearrangeable

Greeks profile

Delta ±1 by construction; gamma, theta and vega cancel to nearly zero. All direction, no optionality: the point of the exercise.

Realistic expectations

Retail traders rarely need to trade synthetics; they need to recognise them. The famous recognition: a covered call's payoff is identical to a short put at the same strike. Every strategy on this shelf has a synthetic twin, and pricing gaps between twins is how professional desks keep the chain honest (which is why the gaps are always nearly zero).

Management rules

• Use parity as a price check: if call minus put differs much from spot minus strike, one quote is stale
• Prefer the real future for pure direction; fewer legs, cleaner margin
• When repairing positions, check whether a synthetic already owns the exposure you are about to buy again

With other strategies

• Covered call = cash-secured put, synthetically: the wheel's two halves are one strategy wearing two costumes, which is why their risk feels identical
• Protective put + holding = long call: Lesson 8's insurance position is synthetically just a call, which explains its payoff shape instantly
• Conversions repair without demolition: adding one leg can flip a position's direction (long call + sell future = long put) instead of paying two tolls to rebuild
• Parity is the fraud detector for "new" strategies: any pitch decomposes into calls, puts and futures; if the decomposition cannot be priced, the pitch is the product

Common mistakes

• Trading synthetics for "cheap futures" while paying naked-short margin anyway
• Missing that an adjusted position has become a synthetic something with different risk
• Treating parity gaps as free money; the toll and stale quotes usually are the gap
