What Is a Call Ratio Spread in Options? Strategy, Payoff, Risk and NIFTY Example

What Is a Call Ratio Spread?

A Call Ratio Spread uses different quantities of call options at different strikes.

A common 1×2 structure is:

•Buy one lower-strike call

•Sell two higher-strike calls

All options normally have the same expiry.

The additional short call creates an asymmetric payoff.

NIFTY Example

Suppose NIFTY is around 25,000.

A trader creates:

•Buy 25,000 Call

•Sell 2 × 25,300 Calls

Assume:

•25,000 Call premium = ₹180

•25,300 Call premium = ₹90 each

Premium received:

₹90 × 2 = ₹180

Net premium:

₹180 − ₹180 = ₹0

This is an illustrative zero-cost ratio spread before transaction costs.

Payoff Above 25,300

Suppose NIFTY expires at 25,500.

Long 25,000 Call:

25,500 − 25,000 = 500 points

Each short 25,300 Call loses:

25,500 − 25,300 = 200 points

Two short calls:

200 × 2 = 400 points

Net payoff:

500 − 400 = 100 points

Ignoring premium and costs.

Payoff Around the Short Strike

At 25,300:

•Long 25,000 Call = 300 points

•Short calls = 0

The structure can therefore have its strongest payoff around the short strike, depending on premium.

The Key Risk

Above the upper short strike, the additional short call causes the payoff to decline.

If NIFTY continues rising substantially, losses can become large.

A standard 1×2 Call Ratio Spread should therefore not be treated as a simple defined-risk spread.

Call Ratio Spread vs Bull Call Spread

A Bull Call Spread uses equal quantities:

•Buy lower-strike call

•Sell higher-strike call

A Call Ratio Spread uses unequal quantities:

•Buy 1 lower-strike call

•Sell 2 higher-strike calls

The extra short call changes the risk profile.

Main Risks

•Strong upside move

•Gap risk

•Implied-volatility changes

•Liquidity and slippage

•Margin requirements

•Expiry sensitivity

Breakevens

Breakevens depend on:

•Strike spacing

•Quantity ratio

•Net premium

Always calculate the complete expiry payoff before entering.

Practical Checklist

1.Identify every leg.

2.Confirm the quantity ratio.

3.Calculate net premium.

4.Map maximum profit.

5.Calculate breakevens.

6.Identify the unlimited-risk region.

7.Stress-test a large NIFTY rally.

8.Check margin.

9.Check liquidity.

10.Define an exit or adjustment plan.

Frequently Asked Questions

Is a Call Ratio Spread bullish?

It can be structured for a mildly bullish or range-bound view, depending on strikes and premiums.

Is the upside risk limited?

Not necessarily. The extra short call can create substantial upside risk.

Is it the same as a Bull Call Spread?

No. The quantities are different.

Can it be used on NIFTY?

Yes, provided suitable contracts and liquidity are available and current specifications are checked.

Final Thoughts

A Call Ratio Spread demonstrates how option quantity changes can create asymmetric risk.

Always consider the payoff near the target strike alongside the risk created by the additional short call.
