Short Straddle


Short Straddle Strategy - High Risk? Not Necessarily!

The short straddle strategy is normally considered to be a risky option trade, due to it's potential unlimited risk should the price action of the underlying move dramatically in either direction. However, as we shall see, if you use the this strategy in combination with a plan to trade the underlying as well, it can not only be minimal risk but quite profitable as well.

Defining the Short Straddle Strategy

In direct contrast to the long straddle where you buy an equal number of both call and put options at the same at-the-money (ATM) strike price and with the same expiration date ... a short straddle involves selling the same number of ATM calls and puts with same expiration date and strike price.

The benefit is that you receive a double credit to your account for the sold options, which can be offset against any adverse movements. Since your objective here is for the price of the underlying to remain as neutral as possible until expiration, you would want your time to expiration to be as short as possible. This is where weekly and short term binary options, some of which have only hours to expiration, may prove a distinct advantage.

If you know anything about options, you'll immediately recognize the risk. Whichever way the underlying moves from now on will put either the call or put options "in-the-money". If your option strikes prices are say $30 and the price suddenly jumps to $45 your call options will be $15 in the money. This means you have to purchase the underlying at $45 in order to deliver it to the market which may "call" it from you at only $30, thus making a $15 per share loss in the process. The further north the price of the underlying goes, the more you lose. The loss is potentially unlimited. In this scenario, you will only have the credit you received from executing the short straddle, to offset the loss.

Short Straddle Option Strategy

One option strategy is to modify the straddle trade so that you protect your risk with buying an equal number of call and put options which are out-of-the-money (OTM). This combination of short and long positions is called a long iron butterfly spread. It is in effect, a double credit spread, facing opposite directions with one set of strike prices laid upon another. You sell the body and buy the wings.


However, there is another strategy where the short straddle can be used in conjunction with trading in the underlying. You can do this with stocks, commodity futures options or forex options.

Let's use a vanilla forex option trading example. The current price of the GBPUSD pair is 1.40. You purchase an ATM short straddle with a very short time to expiration and receive a credit. Immediately, you set up a pending order to either buy the underlying spot market at a price above, or sell it at a price below the straddle. In deciding where to execute your potential spot trades, you take into account the credit from your straddle plus brokerage commissions.

Should the price of the underlying tank, you will automatically enter a spot forex "sell" trade with leverage of 100:1 to the downside. The further it goes south, the more your spot position will make and it will cover losses from the short put option position. Same deal for the upside. If the market remains within the strike prices until expiration time, you keep the initial credit.
