What Is the The position?

The call ratio backspread Nifty IT is a multi leg options strategy that sells calls at one strike and buys a larger number of calls at a higher strike, all on the same expiry. The most common version, the 1 by 2 this trade, sells one call and buys two calls.

The legs of a 1 by 2 call ratio backspread Nifty IT are:

• Sell one call at the lower strike, generating premium and defining part of the risk profile
• Buy two calls at the higher strike, providing unlimited upside exposure through the uncovered extra long call

The first bought call is offset by the short call, forming a standard vertical spread in reverse. The second bought call is uncovered on the upside, meaning the this options approach carries unlimited profit potential if the index rallies significantly, similar to holding an extra outright long call beyond the vertical spread structure.

How Does the Call Ratio Backspread Nifty IT Work?

With Nifty IT at Rs 38,548, a 1 by 2 the spread might sell a call near 38,500 and buy two calls near 38,750. Between the two strikes, the position can show its maximum loss, but beyond the long strike, the uncovered extra long call drives unlimited profit potential as Nifty IT continues to rise.

Nifty IT at Expiry	P&L Per Lot (approx, Rs)	Outcome
At or below 38,500	-0 (net debit lost)	All calls expire worthless; net credit or debit determines outcome
Near 38,750	-6,250 (maximum loss, illustrative)	Short call losses not yet offset by the two long calls
Well above 38,750	Growing profit, unlimited	Extra uncovered long call drives unlimited upside profit
