A Backspread can also be called a Ratio Spread. Backspreads are usually referred to this compilation when the strategy results in a net credit.

A Call Backspread is made up of a short ITM call and long two OTM call options.

The Max Loss is limited to the difference between the two strikes plus the net premium (which should be a credit).

The Max Gain is unlimited on the upside and limited on the downside.


When to use: When you are bullish on volatility and bullish on market price. Note though, that you profit when prices fall, although the gains are greater if the market rallies.

A Backspread looks a lot like a Long Straddle except the payoff flattens out on the downside. The other key difference is that Backspreads are usually done at a credit. That is, the net difference for both legs means that you receive money into your account up front instead of paying (debit) for the spread.

Even though the payoff looks like a "long" type position, it is often referred to as a "short" strategy. Generally it is like this: if you receive money for the position up front it is called a "Short" position and when you pay for a position it is called being "Long".

Hi Jim,

Yes, you're right, a mistakenly typed short instead of long in the first sentence. I think it's fair to remove that sentence.

Good point on the breakeven levels for the backspread vs straddle. I'll do a comparison and add it to the page.

In the Characteristics section, you say that it is similar to a Short Straddle with limited loss on the downside – and then later you say it is like a Long Straddle with payoff flattening out on the downside.

The entire first sentence should be stricken: it's wrong, and you say it more correctly a moment later. It is in fact exactly a long straddle with a flat end, and you can do an identical trade by buying a straddle and selling a put a few bucks down (OTM).

You also should mention that what's nice about this trade is that – because of the credit – it's a less expensive way to put on a Long Straddle, and thus, its breakeven points are closer to your strike, giving you a higher probability of profit on each end.

If the options are American style with a delivery settlement, then yes, you can be called and have to sell the stock at the strike price.

If you aren't holding the stock at the time of exercise then you will go short the stock, which means your broker will borrow the stock for you to deliver to the buyer and charge you a stock borrow fee.

As you short an ITM call, could you be assigned?
What would you do at that moment?

Hi MD, the blue line represents the payoff of the option strategy at the expiration date and the pink link shows you your theoretical profit/loss when the options have 60 days left to expiration.

Can you please explain the graph? I can't understand how to read it.

Hi Kartik, try this page for an example of a call backspread.

Can you please provide one example in order to explain this strategies.

Hi Brett,

Yes, it is more than the net premium...the max loss is the difference between the two strikes less the net premium. Or technically plus the net premium...but as the premium is a credit (-ve) you will subtract it.

I have clarified it above too. Thanks!

BrettMay 20th, 2009 at 6:18am

I'm new to options, but couldn't the loss on a call backspread be much greater than just the net premium? If the market moved above the short ITM call you would have to pay and if the rally did not reach the long OTM calls those would expire worthless and you would be on the hook for the difference in the market and the short call, which could be substantial depending on the strike prices and commodity/stock involved. Do I have this right?
