Calendar Straddle

The calendar straddle is implemented by selling a near term straddle while buying a longer term straddle with the intention to profit from the rapid time decay of the near term options sold. It is a limited profit, limited risk strategy entered by the options trader who thinks that the underlying stock price will experience very little volatility in the near term.

Limited Profit Potential

Maximum gain for the calendar straddle is earned when the stock is trading at the strike price of the options sold on expiration of the near term straddle. At this price, both the written options expire worthless while the longer term straddle being held will suffer only a small loss due to time decay.

Note that maximum profit is limited only on or before expiry of the near term straddle as the options trader has the option of holding on to the longer term straddle to switch to the long straddle strategy which has unlimited profit potential.

Limited Risk

Maximum loss for the calendar straddle is limited and is incurred when the stock price had moved drastically in either direction on expiration of the near term straddle. At this price, both the near-term straddle sold and the long term straddle held will be almost equal in value. The options trader will typically sell the long term straddle to buy back the near term straddle and thus the maximum loss is equal to the initial debit taken to enter the trade.

Example

In June, an options trader believes that XYZ stock trading at $40 is going to trade sideways over the next month or so. He enters a calendar straddle by buying an OCT 40 call for $200 and an OCT 40 put for $200 while simultaneously writing a JUL 40 call for $100 and a JUL 40 put for $100. The net investment required to implement the strategy is a debit of $200.

On near-term option expiration in July, if the stock is still trading at $40, both the written options will expire worthless while the long call and the long put will still be worth $175 each due to a much slower time decay. Selling this long straddle will net $350 to produce an overall profit of $150 after factoring in the $200 initial debit taken.

If instead, the price of XYZ stock had skyrocketed to $60 in July, the written near term straddle will be worth $2000 since the written put will expire worthless while the written call now has an intrinsic value of $2000. The long straddle will also be worth $2000 because while the put will be too far out-of-the-money to be worth anything, the long call will be very deep in-the-money and be worth $2000 (time value for the long call will be almost nothing since it is very deep in-the-money). As such, the options trader can sell the long straddle to offset the losses from the short straddle. Hence, his overall loss is the $200 from the initial debit taken to enter the trade.

Follow-up Action on Near-Term Expiration

Like all calendar strategies, it is necessary to decide on which follow-up action to take when the near-term options expire. This decision depends heavily on the revised outlook of the underlying stock at that time.

Should the options trader thinks that the underlying volatility will remain low, then he may wish to enter another calendar straddle by writing another near term straddle.

If he thinks that the volatility is likely to increase significantly, he may wish to hold on to the long term straddle to profit from any large price movement that may occur.

However, if the options trader is unsure of what to expect of the underlying, it may be best to take profit (or loss) and move on to evaluate other trading possibilities.

Note: While we have covered the use of this strategy with reference to stock options, the calendar straddle is equally applicable using ETF options, index options as well as options on futures.

Commissions

Commission charges can make a significant impact to overall profit or loss when implementing option spreads strategies. Their effect is even more pronounced for the calendar straddle as there are 4 legs involved in this trade compared to simpler strategies like the vertical spreads which have only 2 legs.

If you make multi-legged options trades frequently, you should check out the brokerage firm OptionsHouse.com where they charge a low fee of only $0.15 per contract (+$4.95 per trade).

Similar Strategies

The following strategies are similar to the calendar straddle in that they are also low volatility strategies that have limited profit potential and limited risk.

Calendar Straddle

Definition:
A put option is an option contract in which the holder (buyer) has the right (but not the obligation) to sell a specified quantity of a security at a specified price (strike price) within a fixed period of time (until its expiration).

For the writer (seller) of a put option, it represents an obligation to buy the underlying security at the strike price if the option is exercised. The put option writer is paid a premium for taking on the risk associated with the obligation.

For stock options, each contract covers 100 shares.

Buying Put Options

Put buying is the simplest way to trade put options. When the options trader is bearish on particular security, he can purchase put options to profit from a slide in asset price. The price of the asset must move significantly below the strike price of the put options before the option expiration date for this strategy to be profitable.

A Simplified Example

Suppose the stock of XYZ company is trading at $40. A put option contract with a strike price of $40 expiring in a month’s time is being priced at $2. You strongly believe that XYZ stock will drop sharply in the coming weeks after their earnings report. So you paid $200 to purchase a single $40 XYZ put option covering 100 shares.

Say you were spot on and the price of XYZ stock plunges to $30 after the company reported weak earnings and lowered its earnings guidance for the next quarter. With this crash in the underlying stock price, your put buying strategy will result in a profit of $800.

Let’s take a look at how we obtain this figure.

If you were to exercise your put option after earnings, you invoke your right to sell 100 shares of XYZ stock at $40 each. Although you don’t own any share of XYZ company at this time, you can easily go to the open market to buy 100 shares at only $30 a share and sell them immediately for $40 per share. This gives you a profit of $10 per share. Since each put option contract covers 100 shares, the total amount you will receive from the exercise is $1000. As you had paid $200 to purchase this put option, your net profit for the entire trade is $800.

This strategy of trading put option is known as the long put strategy. See our long put strategy article for a more detailed explanation as well as formulae for calculating maximum profit, maximum loss and breakeven points.

Protective Puts

Investors also buy put options when they wish to protect an existing long stock position. Put options employed in this manner are also known as protective puts. Entire portfolio of stocks can also be protected using index puts.

Selling Put Options

Instead of purchasing put options, one can also sell (write) them for a profit. Put option writers, also known as sellers, sell put options with the hope that they expire worthless so that they can pocket the premiums. Selling puts, or put writing, involves more risk but can be profitable if done properly.

Covered Puts

The written put option is covered if the put option writer is also short the obligated quantity of the underlying security. The covered put writing strategy is employed when the investor is bearish on the underlying.

Naked Puts

The short put is naked if the put option writer did not short the obligated quantity of the underlying security when the put option is sold. The naked put writing strategy is used when the investor is bullish on the underlying.

For the patient investor who is bullish on a particular company for the long haul, writing naked puts can also be a great strategy to acquire stocks at a discount.

Put Spreads

A put spread is an options strategy in which equal number of put option contracts are bought and sold simultaneously on the same underlying security but with different strike prices and/or expiration dates. Put spreads limit the option trader’s maximum loss at the expense of capping his potential profit at the same time.

Understanding Put-Call Parity

Put-call parity is an important principle in options pricing first identified by Hans Stoll in his paper, The Relation Between Put and Call Prices, in 1969. It states that the premium of a call option implies a certain fair price for the corresponding put option having the same strike price and expiration date, and vice versa. [Read on. ]

Calendar Straddle

Put-call parity is an important principle in options pricing first identified by Hans Stoll in his paper, The Relation Between Put and Call Prices, in 1969. It states that the premium of a call option implies a certain fair price for the corresponding put option having the same strike price and expiration date, and vice versa. Support for this pricing relationship is based upon the argument that arbitrage opportunities would materialize if there is a divergence between the value of calls and puts. Arbitrageurs would come in to make profitable, riskless trades until the put-call parity is restored.

To begin understanding how the put-call parity is established, let’s first take a look at two portfolios, A and B. Portfolio A consists of a european call option and cash equal to the number of shares covered by the call option multiplied by the call’s striking price. Portfolio B consist of a european put option and the underlying asset. Note that equity options are used in this example.

Portfolio A = Call + Cash, where Cash = Call Strike Price

Portfolio B = Put + Underlying Asset

It can be observed from the diagrams above that the expiration values of the two portfolios are the same.

Call + Cash = Put + Underlying Asset

Eg. JUL 25 Call + $2500 = JUL 25 Put + 100 XYZ Stock

If the two portfolios have the same expiration value, then they must have the same present value. Otherwise, an arbitrage trader can go long on the undervalued portfolio and short the overvalued portfolio to make a riskfree profit on expiration day. Hence, taking into account the need to calculate the present value of the cash component using a suitable risk-free interest rate, we have the following price equality:

Put-Call Parity and American Options

Since American style options allow early exercise, put-call parity will not hold for American options unless they are held to expiration. Early exercise will result in a departure in the present values of the two portfolios.

Validating Option Pricing Models

The put-call parity provides a simple test of option pricing models. Any pricing model that produces option prices which violate the put-call parity is considered flawed.
