How to Construct a Put Option Ratio Spread in the Futures MarketBuild Futures Options Spread Strategies

Options are eroding assets; therefore, it isn't necessarily wise to spend a substantial amount of money to purchase an option that will face depreciation, as well as dismal odds of success. Instead, it is often a better idea to sell options of different types or strike prices to pay for those that you would like to purchase. A put ratio spread does just that. A trader that is interested in buying a put option in hopes of a market decline, or to simply protect other positions in their trading portfolio, may finance their purchase through the sale of two distant strike priced puts. Here are the details of a put option ratio spread. 

Put Ratio Spread

Buy 1 at-the-money Put
Sell 2 or more out-of-the-money Puts

When to Use a 1 by 2 Ratio Put Spread

Moderately Bearish Option Strategy - When you expect the market to market to move lower, but believe that the downside is limited
Low Cash Outlay in Exchange for Downside Risk - The objective is to put this trade on as a credit, a free trade or very cheap. This occurs when a trader collects more premium for the short options that is put forth for the long options. Free does not entail a lack of transaction costs, margin or risk.

Ratio Put Spread Profit Profile

Possible Profit even if the Option Spread Expires Worthless - If executed at a credit the profit is limited to the premium collected if the market is above the long put at expiration
Limited Profit Potential, but Unlimited Risk - Profit on the down side is limited to the difference between the long and short puts plus the net credit or minus the net debit.  The risk is theoretifcally unlimited on the downside.

What is the Risk of Trading a Put Ratio Write?

• If the market expires above the long put your risk is limited to any premium paid for the spread if executed as a debit
• Because this trade involves more short puts than long the down side risk is unlimited below the short puts
• Having unlimited risk this trade needs to be watched closely


Example of a Commodity Put Ratio Spread:

Perhaps one of the most opportune markets to employ a put ratio spread strategy in the futures market is in the stock indices. This is because of a concept known as the “volatility smile” which tends to keep the value of puts, particularly deep out-of-the-money puts, overvalued. This is because traders know equity markets tend to take the stairs up, but the elevator down. It is a market than can, and will, see precipitous declines from time to time; accordingly, speculators are willing to bid the price of puts higher to increase their odds of being at the right place at a the right time.

Compliments of the volatility smile, it is often possible to construct a put ratio spread strategy using the e-mini S&P futures options providing the trader with a relatively large profit zone at little cost, or maybe even a credit. For instance, with the e-mini S&P 500 futures price near 2185 it might have been possible to purchase a 2050 put with roughly 60 days to option expiration for 32.00 points, or $1,600. The dollar amount is determined by multiplying the premium by $50 (32.00 x $50 = $1,600).

Obviously paying $1,600 for a single option speculation is a rather expensive venture. A trader might opt to finance the purchase of the 2050 put with the sale of 2 1980 puts for 17.00 per option, or 34.00 points. We now know that the dollar value is figured by multiplying the premium by $50; accordingly, selling the 1980 puts would bring in a total premium of $1,700. This creates a credit of $100 to the trader. Simply put, the “market” is paying the trader $100 to participate.

A put ratio spread such as this one be used by the bears as a way to enter the market without the immediate risk that comes with the strategy of selling a futures contract. Put ratio spreads might also be used as a means of hedging existing bullish strategies, in this case it can often be looked at as cheap insurance. For example, a trader that is short a put outright faces unlimited risk, but adding a ratio spread beneath it can be a way to cheaply hedge some of the downside risk. However, this insurance policy has a deductible in the form of downside price risk should the market drop extremely sharply. Let us explain the mechanics by looking at the recommended trade in detail.

Planning and Implementing a Ratio Put Spread

We will assume that the trade above could have been executed at a credit of $100, or at worse even-money. “Even-money” simply means that the trader is collecting the same amount of premium for the short options as is being paid out for the long option. In other words, from a cash outlay standpoint the trade is free. Should the spread be executed as a credit of $100 as expected, the position is better than free in that if it expires worthless the trader still gets to keep the initial $100 in premium collected. Keep in mind that a free trade, or one that provides a credit to the trader, doesn't imply without risk of loss or margin.

This trade involves a long put and two short puts; thus, it faces theoretically unlimited risk beyond the reverse breakeven point. Likewise, the exposure of the short puts creates limited profit potential in that gains on the long put will eventually be offset by losses in the two short puts should the market decline substantially. In this instance, the profit is limited to a handsome sum of $3,600; calculated by multiplying the distance between the long put and the short put by the multiplier for the contract ($50) and adding a credit of $100 ((2050.00 – 1980.00) + 2.00) x $50 = $3,600)).

The simplest way to explain the payout diagram of this trade is based on the potential payout at expiration. Upon expiration of this spread, and assuming a fill of a 2.00 point credit, it will be profitable with the futures price trading anywhere from 2052.00 to 1908 without regard to transaction costs. In essence, the spread makes money as from 2050.00 down to 1980.00. If the e-mini S&P 500 futures price at option expiration is at 1980.00 the option spread trader reaps the maximum profit of $72.00, or $3,600.

If the futures price is below 1980.00 at option expiration, the trade is giving back profits until it runs out of money near 1908.00; this level is known as the reverse break-even point. As the futures price drops below 1980.00, the trader faces theoretically unlimited risk. Such a scenario is similar to being long a futures contract from 1908.00. For every point that the futures price moves below the reverse breakeven point, the trader loses $50. I would like to point out that there is only one way for this trade to be a loser at expiration and that is if the futures market is trading beneath 1908.00, which is 142 points beneath the price of the e-mini S&P 500 futures at the time the trade was initiated. To reiterate, ignoring transaction costs, at any point above 1908 through infinity, the trade is either breaking-even or profitable.




Keep in mind that while this trade does face unlimited risk, the risk is distant from the market price at the time of entry. This is in stark contrast to the risk faced by a futures trader. I have learned that you can never underestimate the markets, but the odds of a 142 point drop in the e-mini S&P in the next 60 days prior to option expiration, isn’t necessarily high.
Put Ratios for Risk Management

As mentioned above, this trade can be used as an insurance policy. I have been known to point clients toward a trade similar to this one as a means of providing a quasi-hedge against short put positions that are under pressure. At expiration, this spread insures a move below 2050.00 to 1980.00 tick for tick. As explained, below 1980.00 the trade gives back profits...thus the insurance policy begins to become less valuable. Below 1908, the trade that was intended to be a hedge short put options, now becomes a burden that results in even more losses. Therefore, when using ratio spread as a means of risk management you should be aware of major support and resistance levels and place the strike prices of the spread accordingly. You don’t want your “cheap” risk management technique to become an expensive lesson.

Disadvantage of Ratio Put Spreads

It is important to note that a ratio spread can sometimes involve unintended consequences at any point prior to expiration. At option expiration, there is no time value in the options and the profit and loss will be strictly dependent on the aforementioned calculations. Nevertheless, due to the time value still present in the option premium, it is possible for a spike in volatility to create a scenario in which the combined value of the short puts gain in value faster than that of the long put. In other words, it is possible for the market to move in the anticipated direction but create a loss to the trader. Assuming that the futures contract is trading above the reverse break even at expiration the losses will be only temporary; however it is never fun to be a part of an explosion in volatility which turns a good directional speculation into a losing trade.

Conclusion on Ratio Write Option Trading

Ratio spreads can be a powerful trading tool but proper construction and execution are key in producing favorable results. Poor timing in terms of volatility and price, along with incorrect strike price placement, might result in a very unpleasant trading experience.
