Synthetic Long Nifty Midcap Select: Setup, Payoff and Risk Guide

The this strategy works because of the mathematical relationship between calls, puts, and the underlying known as put call parity. Buying a call and selling a put at the same strike and expiry produces a combined position whose value changes with the underlying in almost the same way as owning the underlying directly, or in this case, holding a long futures position.

Unlike the defined risk or partially defined risk strategies covered elsewhere in this series, the synthetic long Nifty Midcap Select carries the same unlimited profit and unlimited loss potential as an actual long futures position. It is not a premium collection or risk reducing strategy; it is a direct substitute for holding the underlying.

What Is the The position?

The synthetic long Nifty Midcap Select is a two leg options position that buys a call and sells a put at the same strike, typically at the money, and the same expiry. Together, these two legs replicate the payoff of a long futures position on Nifty Midcap Select.

The two legs of the this trade are:

• Buy an at the money call at the chosen strike, which provides unlimited upside participation
• Sell an at the money put at the same strike, which creates the downside exposure that mirrors an actual long position

Because the call is purchased and the put is sold at the same strike, the combined position's value moves in close correspondence with Nifty Midcap Select itself. If Nifty Midcap Select rises, the long call gains value while the short put loses value at a similar rate, and the reverse occurs if the index falls, replicating the linear payoff of a futures position through the synthetic long Nifty Midcap Select.

How Does the This options approach Work?

With Nifty Midcap Select at Rs 13,850, a synthetic long Nifty Midcap Select would typically use the ATM strike of approximately 13,850, buying the call and selling the put at that same strike and expiry. The net cost, whether a small debit or credit, reflects the difference between the call and put premiums, which is generally small for at the money options and relates closely to the cost of carry embedded in the futures price.

The spread: Step by Step Setup

1. Identify the ATM strike from the Nifty Midcap Select option chain. With Nifty Midcap Select at Rs 13,850, the ATM strike for the synthetic long Nifty Midcap Select is approximately 13,850.
2. Buy the ATM call at the chosen strike. This is the first leg of the this strategy, providing the upside participation.
3. Sell the ATM put at the same strike. This is the second leg, and it must be placed at the same strike and expiry as the call for the synthetic long Nifty Midcap Select to closely replicate futures like exposure.
4. Calculate the net debit or credit. This equals the call premium paid minus the put premium received, multiplied by the lot size, for the synthetic long Nifty Midcap Select.
5. Treat the position like a futures trade for risk management purposes. Because the synthetic long Nifty Midcap Select has unlimited risk in both directions, apply the same stop loss and position sizing discipline you would use for an actual long futures position.

Illustrative Payoff: Synthetic Long Nifty Midcap Select

Illustrative example for educational purposes only. The synthetic long Nifty Midcap Select carries unlimited profit and unlimited loss potential, similar to a long futures position. Strikes and premiums are hypothetical and should not be interpreted as a trade recommendation.

Hypothetical setup: Buy 13,850 CE at Rs 195 per unit. Sell 13,850 PE at Rs 185 per unit. Net debit: Rs 10 per unit. Lot size: 120 units.

Nifty Midcap Select at Expiry	P&L Per Lot (approx, Rs)	Outcome
1,000 points below 13,850	Large loss, approximately -120,000 (before net premium adjustment)	Position moves against the index one for one, like a short futures loss
At 13,850 (unchanged)	Approximately -1,200 (net premium only)	Both options largely offset; only the net debit or credit remains
1,000 points above 13,850	Large gain, approximately +120,000 (before net premium adjustment)	Position moves with the index one for one, like a long futures gain

This payoff table illustrates why the synthetic long Nifty Midcap Select is described as replicating a futures position: the gains and losses scale directly with the index's movement, without the capped profit or defined loss features seen in spread based strategies covered elsewhere in this series.

Greeks for the Synthetic Long Nifty Midcap Select

Delta: The synthetic long Nifty Midcap Select has a delta close to 1 (or 100 in percentage terms), meaning the position's value changes almost one for one with Nifty Midcap Select, similar to holding an actual futures position.

Gamma: The synthetic long Nifty Midcap Select has relatively low net gamma compared to single option positions, since the long call's positive gamma and the short put's negative gamma largely offset each other.

Theta: Theta for the synthetic long Nifty Midcap Select is generally small in net terms, since the time decay on the long call and the short put tend to offset one another, unlike premium collection strategies where theta is a primary profit driver.

Vega: The synthetic long Nifty Midcap Select has minimal net vega exposure, since the long call's positive vega and the short put's negative vega largely cancel out, making the position relatively insensitive to changes in implied volatility.

When the Synthetic Long Nifty Midcap Select May Be Considered

The synthetic long Nifty Midcap Select may be considered when a trader wants futures like directional exposure but prefers to work within the options market, perhaps due to margin treatment, existing options positions, or strike specific considerations; when the options market offers more favourable pricing or liquidity than the futures market at a given moment; or as a component of a more complex multi leg strategy that requires futures like exposure alongside other options positions.

When NOT to Use the Synthetic Long Nifty Midcap Select

Consider avoiding the synthetic long Nifty Midcap Select when you want defined or limited risk, since this strategy carries the same unlimited loss potential as an actual long futures position; when a simple futures contract would be more straightforward and cost effective; or when you are not prepared to manage a position with futures like risk using options mechanics.

Risk Management

Because the synthetic long Nifty Midcap Select carries unlimited risk in both directions, it should be managed with the same discipline as an actual futures position: a predetermined stop loss level, appropriate position sizing relative to account size, and awareness that both the call and put legs need to be closed together to fully exit the synthetic long Nifty Midcap Select.

Transaction Costs

The synthetic long Nifty Midcap Select involves two option legs, each with its own transaction costs at entry and exit. Brokerage, exchange transaction charges, STT, GST, SEBI charges, stamp duty, and bid ask spread impact on both legs should be compared against the cost of simply trading Nifty Midcap Select futures directly, which may be more transaction cost efficient for pure directional exposure.
