Call Ratio Back Spread in Indian Share Market: A Comprehensive Guide

In the Indian share market, advanced trading strategies such as the Call Ratio Back Spread offer traders a way to manage risk while taking advantage of market volatility. This strategy is popular among experienced options traders looking for a potential profit during both sharp upward and downward price movements.

In this detailed guide, we will explore the Call Ratio Back Spread, including how it works, when to use it, and what its advantages and disadvantages are. Historical data and real-world examples will also be provided to give you a better understanding of this complex strategy.

What is a Call Ratio Back Spread?

The Call Ratio Back Spread is an options trading strategy that involves buying more call options than selling. It is designed to benefit from significant price movements in either direction, though it is primarily a bullish strategy. Unlike simpler options strategies, the Call Ratio Back Spread offers a limited loss potential and unlimited profit potential if the underlying stock price rises significantly.

Components of a Call Ratio Back Spread:

Selling Call Options: The trader sells a smaller number of call options at a lower strike price.
Buying Call Options: The trader buys a larger number of call options at a higher strike price.

This strategy is typically set up in a 1:2 or 1:3 ratio, meaning that for every call option sold, two or three are bought. The idea behind the strategy is to cover the cost of the purchased options using the premium earned from selling the options.

How Does the Call Ratio Back Spread Work?

The Call Ratio Back Spread relies on the volatility of the market. If the price of the underlying stock increases significantly, the trader can profit from the extra call options purchased. If the stock price stays relatively stable or decreases slightly, the losses are limited to the net premium paid for the strategy.

Example Setup: Assume that a stock is trading at ₹500, and a trader expects significant volatility. They execute a Call Ratio Back Spread by:

Selling 1 call option with a strike price of ₹520.
Buying 2 call options with a strike price of ₹540.

The premium collected from selling the ₹520 call helps offset the cost of buying the ₹540 calls. If the stock price rises sharply above ₹540, the trader stands to make a significant profit. However, if the stock remains between ₹520 and ₹540, the trader incurs a loss limited to the net premium.

Break-Even Points: There are typically two break-even points in this strategy:

Lower Break-Even: Calculated based on the net premium received or paid.
Upper Break-Even: Calculated using the formula: UpperBreak−Even=StrikePriceofLongCall+(PremiumPaid/NumberofCallsBought−1)Upper Break-Even = Strike Price of Long Call + (Premium Paid/Number of Calls Bought – 1)UpperBreak−Even=StrikePriceofLongCall+(PremiumPaid/NumberofCallsBought−1)

Payoff Structure: The payoff of a Call Ratio Back Spread can be visualized as follows:

Stock Price at Expiration (₹)	Net Premium (₹)	Profit/Loss (₹)
< 520	Premium Earned	Loss Limited
Between 520 and 540	Net Premium Paid	Small Loss
> 540	Significant Profit	Unlimited Profit

When to Use a Call Ratio Back Spread?

A Call Ratio Back Spread is best used in the following scenarios:

Expecting High Volatility: The strategy thrives when traders expect significant movement in the stock price but are uncertain about the direction.
Bullish Sentiment: Though the strategy can profit from downward movements, it is generally more effective in bullish markets where large upward price movements are anticipated.
Hedging Strategies: Traders use this strategy as a hedge against existing short positions.
