Put Ratio Back Spread

The Put Ratio Back Spread is a strategic options play used when you expect significant downward movement in the underlying asset but want to limit potential losses if the asset price increases. This strategy involves selling a lower number of put options at a higher strike price and buying a greater number of put options at a lower strike price. The result is often a net credit or minimal cost and offers the potential for substantial profit if the asset declines sharply, while limiting losses on an upward price move.

How It Works​

  1. Sell Higher Strike Put:

    • Collect a premium by selling fewer in-the-money or near-the-money put options.

  2. Buy More Lower Strike Puts:

    • Use the premium to buy a greater number of out-of-the-money put options.
    • This position profits significantly if the asset price drops below the lower strike price.

  3. Net Credit or Minimal Cost:

    • The strategy often results in a net credit, but sometimes a small debit depending on the strike prices and premiums.

Example​

Consider a stock trading at ₹100:

  • Sell 1 Put Option with a ₹100 strike for ₹5.
  • Buy 2 Put Options with a ₹90 strike for ₹2.5 each.

Net Cost:​

  • ₹5 (collected) - ₹5 (paid) = ₹0 (no cost).

Outcomes:​

  1. If the stock drops well below ₹90:

    • The ₹90 puts gain significant value, leading to large profits.

  2. If the stock remains above ₹100:

    • All options expire worthless, and no profit or loss occurs.

  3. If the stock drops only slightly:

    • You incur a limited loss as the value of the sold put offsets part of the gain on the purchased puts.

When to Use It​

  • Market Outlook:

    • Ideal when you expect significant volatility and are highly bearish on the asset.
    • Provides protection if the decline is moderate or the price increases.

  • Volatile Conditions:

    • Best used before major announcements, earnings releases, or events that could trigger sharp price movements.

Advantages and Disadvantages​

Advantages:​

  • Unlimited profit potential if the underlying asset declines sharply.
  • Minimal or no cost to initiate the strategy, often generating a net credit.
  • Limited loss if the price moves against you.

Disadvantages:​

  • Loses money if the asset price drops only slightly and stays between the strike prices.
  • Requires a strong directional view; profits are limited if the asset remains range-bound.
