Options Mastery Lesson: Straddles

admin — Tue, 26 Jan 2010 02:16:44 +0000

In our previous reports, we discussed option strategies that feature the use of options in combination with stock such as the buy-write and the use of options against each other in the form of spreads. We will focus on the Straddle, which uses options in unison with each other.
Unlike a spread that features a long option versus a short option, the Straddle features one position (either long or short) and two options – a call and its corresponding put. A Straddle is the strategy composed of a long (or short) call and a long (or short) put where both options have the identical strike price and expiration month.
When putting together a Straddle, the construction should be as follows:
-Different options (call and its corresponding put)
-Same stock
-Same strike
-Same expiration
-One-to-one ratio
Straddle positions are referred to as ‘long Straddle’ or ’short Straddle’ depending on whether you purchase the call and its corresponding put (long) or sell the call and its corresponding put (short). For example, we will construct the long Straddle by purchasing both the July 60 call and the July 60 put. We will construct the short Straddle by selling both the July 60 call and the July 60 put. It is important to note that the Straddle is a one-to-one ratio strategy. For every call that you buy (or sell), you must purchase (or sell) exactly one corresponding put.
Straddle Scenarios
The Straddle relies on movements in stock price or in implied volatility to establish profit opportunities. The Straddle buyer looks for the stock to move aggressively in either direction or for the anticipated perception of possible aggressive moves that will bring about an increase in implied volatility.
Sellers of the Straddle hope for the opposite scenario. A lack of stock movement or a perceived lack of movement, causing implied volatility to decrease, will create profitable scenario.
Straddle Mechanics
Let’s look at how a Straddle works. In our illustration, we see the July 65 Straddle. We can either buy or sell the Straddle. If we purchase both the July 65 call and the July 65 put simultaneously in a one-to-one ratio we have a long Straddle. To construct a short Straddle we would sell both the July 65 call and July 65 put simultaneously in a one-to-one ratio.
Continuing with our illustration, we will set the price for each of the options. With our imaginary stock trading at $65.50, the July 65 call trades at $3.13 and the July 65 put trades at $2.47. The combination of these two prices accounts for the $5.60 cost of the Straddle. Fast forward to expiration and observe what happens to the value of the Straddle at different stock prices.
Price Call Put Straddle P & L
50 0.00 15.00 15.00 9.40
55 0.00 10.00 10.00 4.40
60 0.00 5.00 5.00 -.60
65 0.00 0.00 0.00 -5.60
70 5.00 0.00 5.00 -.60
75 10.00 0.00 10.00 4.40
80 15.00 0.00 15.00 9.40
As you can see, the Straddle’s value increases the further the stock moves away from the strike. The closer the stock is to the strike, the lower the value of the Straddle at expiration. The chart clearly shows that the more the stock moves away from the strike, the higher the Straddle’s value becomes. Conversely, the closer the stock finishes to the strike, the lower the value of the Straddle. Owners of Straddles want and need movement while sellers of Straddles want and need stagnation.
How does this example influence your investment strategy? If you feel that a stock is likely to move aggressively in either direction or if you feel that implied volatility is likely to increase, possibly due to impending news (such as earnings, FDA approval, etc.), look into the purchase of a Straddle. If you feel a stock is likely to enter a stagnant phase, or if you feel that implied volatility is likely to decrease, the sale of a Straddle can be a very profitable trade for you.

Options Trading Mastery: Rolling the Position

admin — Sun, 24 Jan 2010 02:13:26 +0000

The selection and management of a vertical spread are only two-thirds of the game. Closing out, rolling or morphing the position has to be analyzed and executed with the same due diligence.
Looking at the closing out of a vertical call spread, we find there are three possible outcomes. The spread can finish out-of-the-money and valueless. For a call spread, this scenario occurs when the stock closes at or below the lower strike of the spread. In order to close out the spread, an investor would just let it expire. Both options finish out of the money so there is no residual position left over.
If the spread finishes fully in-the-money (at maximum value), meaning both options in-the-money, both options are exercised. You will exercise your long call and your short call will be assigned. They cancel each other out leaving you with no residual position. This scenario occurs when the stock price closes lower than the lower strike call involved in the spread.
Investors encounter a difficult scenario when a stock closes in between the two strikes of the spread. This creates a situation where one strike winds up being in-the-money while the other ends up out-of-the-money. When both options expire in-the-money, they are both exercised. One creates a long stock option, the other a short position canceling each other out. This is not the case here. The option that is in-the-money leaves a residual stock position. Since the other option is out-of-the-money, it cannot offset the residual stock position created by the expiring in-the-money option.
Two actions are possible in this scenario. One involves trading out of the spread on expiration Friday just before the close. Because of the bid/ask spread of the two options, you will probably have to give away some of your profits in order to close out the position. This may be the best thing to do in order to avoid naked, unlimited risk.
If you only trade out of the in-the-money option, you run the risk that the stock moves adversely and the out-of-the-money option suddenly becomes in-the-money. This risk is short-lived because you are doing this late on expiration day of the expiring month. If this happens, you will be naked in the residual stock position.
If there is still time, you can always trade out of the option, but that is very risky. If the stock is at a relatively safe distance from the out-of-the-money option, you may want to just close out the in-the-money option and let it expire worthless.
The two factors that must be considered are: the combination of the distance of the strike from the stock price in relation to the short amount of time for the stock to get there, and the amount of money saved by not buying back the out-of-the-money option. Remember, this takes place at the very end of the day on expiration day. These options only have minutes of life left. The risk is somewhat mitigated, but still there nonetheless.
The catch is the proximity of the stock to the out-of-the-money option. If the stock is close to the out-of-the-money option, it is best to trade out of the spread entirely.
As stated before, if the stock closes either with the spread fully in-the-money or out-of-the-money, the position will adjust itself through the exercise process leaving no residual position. If the stock price finishes between the two strikes, there will be a residual position.
We discussed how to trade out of this position. Your second choice is not to trade out and allow yourself to go through the expiration process. You must remember that if you are going to accept a residual stock position, you must be able to afford it.
If you have 10 July 50 calls and you exercise them, you will be receiving 1000 shares of stock at $50.00 per share. Thus, you must have $50,000.00 of cash and/or margin in your account to receive the stock. If you do not have enough cash and/or margin to accept delivery of the stock, then you must trade out of the position before it expires.

Options Trading Lesson: Closing the Time Spread Position

admin — Sat, 23 Jan 2010 03:20:18 +0000

It is important to remember that the time spread will leave you with several potential positions that can be altered by other options or stock in numerous ways.
There are a number of decisions you must make to clarify your understanding and goals. Being open to a number decisions can be a very good thing for the flexibility of your position, whether entering or exiting trades. In this example we’ll look at the position you have and the ways you can make your decisions.
First, it is important to understand what position you are going to be left with when the near-month option expires.
Second, you must form your opinion of what you think the stock is going to do (formulate a bullish or bearish lean) and then figure out the best way to take advantage of that opinion.
Next, you must figure out how to adjust your present position and change it into an advantageous position for a profitable outcome. That might mean selling out of the position totally. Your changes to the position must not only be correct, but also done in the most efficient, cost-effective manner including keeping commission prices down.
It is also important to note that you should make sure to go from a hedged position to another hedged position to ensure proper risk management.
Concluding Thoughts
The time spread is an excellent strategy for premium sellers who want to capture premium in a hedged way. It is best used in stagnant periods when a stock is likely to remain in a tight price range. It is less expensive and less risky than most other premium collecting strategies thus is friendlier to investors who are short on capital and experience. It can also be used to take advantage of volatility changes and even some directional stock movements.
The time spread can leave you with a residual naked position that needs to be managed for risk at expiration of the front month option. As always, it is important to fully understand the risks and rewards of the strategy and the potential risks and solutions of the residual position before executing the strategy. Don’t take this too lightly.
The residual position does allow you many choices including closing out the position totally, or continuing the position by combining it with either stock or another option to create a new position that fits the investor’s new expectations for the stock.

Options Trading Mastery: Vertical Spread Recap

admin — Fri, 22 Jan 2010 15:33:45 +0000

Vertical spreads can have various names. The same vertical spread could be called several different things by several different people. We have used two terms only: vertical call spread and vertical put spread. Each of these two spreads allows for two positions, long and short.
The long vertical call spread is constructed by buying one call option with a lower strike price while simultaneously selling another call option in the same month with a higher strike price. In a one to one ratio this trade, the long vertical call spread, is labeled a bullish trade. This means that when engaging into a long vertical call spread, the investor expects the stock to increase in value. An investor who engages in a trade with the expectation of the stock going up is said to be bullish. Thus, a long vertical call spread is a bullish trade.
For example, you are long a vertical call spread if you buy 10 August 35 calls and sell 10 August 40 calls. The proper way to describe this would be “long the August 35 – 40 call spread.” Using our previous example of the August 35 – 40 call spread, we assume that you bought the spread for $2.80. At expiration, you know that you can lose a maximum of $2.80 if the stock closes at $35.00 or below. At expiration, you will gain your maximum profit if the stock is $40.00 or over. Your maximum profit is defined as the difference between the two strikes minus the amount you paid for the spread.
Vertical spread’s maximum profit = (difference between the two strikes) – (amount paid for spread).
In this case, the difference between the two strikes equals $5.00. That $5.00 minus the $2.80 you spent on the spread leaves you with a maximum potential gain of $2.20, and represents a 78.5% return. The potential maximum loss is $2.80 or the full value of the investment.
The chart below shows what this spread will do over the course of a range of stock values.
A short vertical call spread is constructed by selling a call with a lower strike price, while simultaneously buying a call in the same month with a higher strike price. Since owning a vertical call spread created a long position for the owner, then the seller of the vertical call spread must be short. An investor who takes a short position anticipates a decrease in the price of a stock and is considered to be bearish on the stock. Thus, a short vertical call spread is considered a bearish position.
Using our example, say you are short 10 August 35 calls and long 10 August 40 calls. The short vertical spread is set up in the proper ratio and in the same month. For the sale of the spread you received $2.80. Your maximum potential gain is the $2.80 that you received from the sale and would be obtained if the stock closed $35 or below.
The maximum loss is calculated by taking the difference between the two strikes and subtracting the sales price of the spread from it. The difference between the two strikes is $5.00 (40-35). From that we subtract the price of the spread which is $2.80 and we are left with $2.20. This $2.20 is the maximum potential loss for a seller of this spread. The formula is given as: The difference between the two strikes – the price of the spread = total potential maximum loss.
The maximum profit for the seller of a vertical call spread is attained when the price of the stock closes at or below the lower priced strike. And the maximum loss is attained when the stock closes at the higher strike.
The vertical put spread functions in much the same way as the vertical call spread just in the opposite direction. Like the vertical call spread, the construction of the vertical put is done in a one to one ratio. The vertical put spread is constructed by purchasing one put and simultaneously selling another put in the same month but in a different strike.
A long vertical put spread is considered to be a bearish trade. This means that the purchaser of a vertical put spread is expecting the stock to go down. Further, a long vertical put spread is considered a debit spread which simply means that the purchaser had to put out money to buy the spread. Now, if the stock proceeds down, the spread’s value will expand. As stated before, a spreads maximum value is equivalent to the difference between the strikes. On the other hand a spreads minimum value is $0.
In the case of a put spread, maximum value is attained when the stock trades at or below the lower strike. Conversely, a put spread’s minimum value is attained when the stock trades to the higher strike.
For example, suppose we purchase the August 50-55 put spread for $3.00. To set up this trade, we would have bought the August 55 put and sold the August 50 put. If the stock trades down to 50 or below at expiration, the spread will be worth its maximum value of $5.00 (difference between the two strikes: 55-50).
Since you bought the spread for $3.00 and it is now worth $5.00, you have a $2.00 profit which represents a 66.6% profit on your $3.00 investment.
On the downside, the most you can lose is the $3.00 you spent for the spread and this will happen if the stock closes $55 or above. If the stock was to close at $55, the August 55 put would be worthless because it would be equal to the stock price thus valueless. The August 50 put would also be worthless being that it is $5.00 out-of-the-money. The difference between these two values would obviously be $0. Below, the chart shows the value of the spread at different stock prices.
A short vertical put spread is constructed by purchasing a put with a lower strike price while simultaneously selling a put with a higher strike in the same stock in the same month and in a one to one ration. For example buying one Feb 65 put while selling one Feb 70 put or buying 10 May 20 put while selling 10 May 30 put. It is considered to be a bullish trade because the seller expects the stock to go up or increase in value. Further, it is considered a credit spread meaning that you receive cash into your account upon execution of the trade.
Say you were to sell the June 50 – 60 put spread for $5.50. As the seller, your maximum profit will be the $5.50 you received for the sale of the spread. The maximum profit will be attained if the stock closes at $60.00 or above. At that level, both the June 50 and 60 puts will be worthless because both will be out-of-the-money. Thus, the spread will have no value.
The maximum loss of the trade will be defined by the difference between the two strikes minus the amount you received from the sale of the spread. In this case, the difference between the strikes is $10.00 (60 strike – 50 strike). The spread was sold for $5.50 so $4.50 is the maximum loss of the position to the seller.
In conclusion, vertical spreads provide the buyer and the seller an excellent percentage return while, at the same time, provide limited loss scenarios. Vertical spreads allow for two types of bullish trades, the purchase of a vertical call spread or the sale of a vertical put spread. On the other hand, vertical spreads offer two bearish trades; the purchase of a vertical put spread and the sale of a vertical call spread.
So, if you want to take advantage of a directional stock movement (either up or down) but you are not interested in taking a longer term, possibly capital intensive position, then look to using the vertical spread due to its favorable risk reward scenario.

Options Trading Mastery: Time Decay and Volatility Trading Opportunities

admin — Fri, 22 Jan 2010 02:39:19 +0000

When vertical spreads are mentioned, they quite often come with monikers such as ‘bull’ and ‘bear’. This lends most to think of vertical spreads as directional plays which is true. However, vertical spreads can be used to take advantage of two other potential trading opportunities – time decay and volatility movement.
If you are looking for a fully hedged way to take advantage of time decay, a vertical spread can be an excellent tool. Knowing a little about them now, you will recall that a vertical spread has a limited profit potential but also a limited loss scenario for both the buyer and the seller. So, how do we use this covered trade to take advantage of time decay.
At-the-money options have more extrinsic value than their similar month in-the-money or out-of-the-money options. Since it is an option’s extrinsic value that decays away over time, you could set up a vertical spread by selling an at-the-money option and buying either the out-of-the-money option (creating a credit spread) or buying an in-the-money option (creating a debit spread). If the stock holds tight to the out-of-the-money option, the option’s extrinsic value will decay away at a faster rate than either the in-the-money option or the out-of-the-money option due to the fact that the at-the-money option has more total extrinsic value to decay in the same amount of time as the others.
Creating the vertical spread by selling an at-the-money option and buying an out-of-the-money or in-the-money option as a hedge looks like a good idea, but now there are a couple choices. Should you do the put spread or the call spread? Should you buy it or sell it? The decision of what to do from here should first be based on which way you think the stock will move. Although you are playing for time decay and you are assuming an overall lack of movement, you can’t expect the stock not to move at all. So even though you are playing time decay, you still want to form an opinion about in which direction the stock is most likely to move. By doing this, you’ve now give yourself another way of making the trade profitable. You are playing for a lack of movement but now you can still win if you pick the right direction. This scenario presents you with two ways to win and only one to lose.
Now that you have picked which at-the-money strike you are going to sell and you’ve picked your anticipated stock position you still have a decision to make. Do you do the call vertical spread or the put vertical spread? Remember both the vertical call spread and a vertical put spread allow you to participate in either stock direction. For the bulls, you can buy a vertical call spread or sell a vertical if you think that the stock will go up. For the bears, you can buy a vertical put spread or sell a vertical call spread. For each direction there are two choices to decide from. One is a purchase, one is a sale. The best way to decide which to do, other than your own style or comfort ability is a simple risk/reward analysis.
By selecting an at-the-money option to sell as part of a vertical spread, an investor can execute a time decay play with a hedged position.
Much in the same way that a vertical spread can be used as a time decay play, it can be used as a volatility play. We stated earlier that an at-the-money option has more extrinsic value than any other option in its expiration month. This is due to a number of contributing factors including time but it is in no small way due to volatility. Volatility is a huge component of an option’s extrinsic value. An option’s dollar sensitivity to movements in implied volatility is known as vega. Obviously, an at-the-money option will have a higher vega (volatility sensitivity) then will an in-the-money or out-of-the-money option in the same month.
As volatility increases, the at-the-money option will increase in price to a greater degree than will an in-the-money or out-of-the-money option in the same month. As volatility increases, the at-the-money option will increase in price to a greater degree then will an in-the-money or out-of-the-money option whose vega’s will be less. Conversely, the at-the-money option will lose value at a greater rate than an in-the-money or out-of-the-money option should implied volatility decrease. The question now is how to use the vertical spread to take advantage of anticipated movements in implied volatility. Remember, the vertical spread affords you the luxury of being hedged on either side of the trade – both as a buyer and a seller of the spread.
So, if you think that implied volatility is likely to increase, you can set up a vertical spread by buying an at-the-money option and selling either the in-the-money or out-of-the-money option against it. Conversely, if you feel implied volatility will decrease; you can set up a vertical spread by selling an at-the-money option and buy either an out-of-the-money or an in-the-money option against it.
As to how to set it up, you would follow the same guidelines as you would for setting up a vertical spread to take advantage of time decay. Decide which direction you feel the stock would most likely move. If you feel the stock would most likely rise, you will have to decide between buying a vertical call spread and selling a vertical put spread.
Either way, the spread will have to be constructed with the at-the-money option being long if you feel volatility will increase or short if you feel volatility will decrease. If you feel the stock would most likely fall, you will have to decide between buying a vertical put spread and selling a vertical call spread. Again, either way, the spread will have to be constructed with the short option being the at-the-money.
As you can see, the vertical spread does not have to be used only in directional scenarios. It is very versatile allowing the investor several choices among a diverse group of potential uses. It also affords limited risk, albeit limited profit potential, to both the buyer and the seller.

Options Trading Mastery: Behavior of the Time Spread

admin — Tue, 19 Jan 2010 14:58:26 +0000

Time spreads can be a profitable investment strategy if you understand the concept of time decay. A time spread is designed to take advantage of the fact that an options decay curve is non-linear, that is, an option’s value does not decay evenly over time. As an option gets closer to expiration, its rate of decay increases meaning the option loses value more quickly. That decay rate increases progressively until expiration.
An option’s decay rate begins to accelerate when the option is about 45 days out. It picks up steam at 30 days out and really comes under decay pressure at about 15 days out. This scenario is similar to a boulder rolling down from a hilltop. As it starts, it rolls slowly, then gains more speed, and momentum the further it gets down the hill until it achieves its maximum speed at the bottom. Option decay acts the same way – gathering speed and momentum as the option approaches expiration.
In time spreads, both options have the same strike price that remains constant. Each option’s value decays at different rates and over different lengths of time. The option, with one month until expiration, experiences value decay at a faster rate than the one with three months until expiration.
If you buy an option with three months to go and sell an option with the same strike but with one month to go, you have set up a spread between the two options values (prices). As time passes, your short option loses value more quickly than your long option that decays more slowly. The value of the spread widens and you profit from that spread’s expansion. This is the fundamental behavior of the time-spread.
Consider that you are long the 60-30 day time spread. That means you are long the 60-day option and short the 30-day option. We will assign a price of $3.00 to the 60-day option and $2.00 to the 30-day option. Since you pay for the one and receive payment for the other, the bottom line cost of what you put out for the spread is $1.00.
During the same 30-day period, it goes from $3.00 to $2.00. Remember, the spread’s bottom line cost was $1.00. The 30-day option (now expired) will be worth $0 while the 60-day option (now a 30-day option) will be worth $2.00. If you had invested in this spread, after 30 days decay you would be holding one option worth $2.00. The investment has provided a nice return!
This is an ideal situation. The stock price and volatility remain constant and you capture the decay. The time spread has worked just as it should. It does work that way sometimes, but nothing works as it should all the time. As we know, stock prices and volatility levels do not remain constant. They are always changing. In the time spread strategy, the investor must choose opportunities carefully. In addition to picking a stock that will be in a stagnant period, the investor should look for two other situations where the spread has profit possibilities: changes in volatility and to a lesser degree stock price movements.

Options Trading Mastery: Understanding Spread Prices

admin — Tue, 19 Jan 2010 01:59:15 +0000

During the life of a vertical call spread, the spread will trade between its minimum and maximum values (between 0 and the difference between the two strikes). In the case of a vertical call spread, the spread will trade closer to zero when the stock trades closer to or lower than the lower strike price. The spread will trade closer to maximum value when the stock trades closer to or higher than the higher strike price.
Starting from a stock price of 37.5, a price located directly between the two strikes, (using our example of the August 35 – 40 call spread) we can see the approximate value of the spread is roughly $2.5 dollars. This is because the August 35 calls and the August 40 calls are equidistant from the current stock price of $37.50. Being equidistant from the stock, both the August 35 and 40 calls will have almost the same amount of extrinsic value in them. Thus, in the spread, the extrinsic values of the two options cancel themselves out since you are long one call and short the other. This would leave each option value consisting of only intrinsic value. With the stock at $37.50 the value of the August 35 – 40 call spread will be $2.50. The August 35 calls will have $2.50 in intrinsic value while the August 40 calls will have $0 in intrinsic value. The difference gives you a spread with a value of $2.50.
A general rule of thumb is: if the stock price is located evenly between the two strike prices, the vertical spread should be worth roughly half of the value of the distance between the two strikes. This will be true for vertical put spreads as well as call spreads. From this rule, we can roughly estimate the vertical spread’s price per different stock prices.
For vertical call spreads, if the spread is worth roughly half of the difference between the two strikes with the stock price directly between the two strikes, then as the stock falls to lower strike and beyond, the spreads value will decrease and move closer to $0. Time left until expiration and volatility will dictate how close and how quickly it will approach $0. On the other side, as the stock climbs toward and above the upper strike, the spreads value will increase toward its maximum value described by the difference between the two strikes.
For vertical put spreads, as the stock price decreases toward the lower strike price, the spread will increase in value and approach its maximum value as defined by the difference between the two strikes. As the stock price increases toward the higher strike, the spread will decrease in value and will approach $0. Again, time until expiration and volatility will determine how quickly and how close the spread will approach $0.

Options Trading: Intrinsic Value and the Vertical Spread

admin — Mon, 18 Jan 2010 14:30:06 +0000

An investor must always keep in mind that vertical spreads have an intrinsic value. This means it is possible to consider them ‘in the money.’ If a vertical spread has an intrinsic value, it can also have an extrinsic value. Unlike maximum intrinsic values that equal the difference between the strikes at expiration, maximum extrinsic value deviates from spread to spread based on several factors.
During a vertical spread’s life, its price will fluctuate between zero and the value of the difference between the two strikes. An investor can determine the price of the spread, at any given time, by the location of the stock and the time until expiration.
At expiration, what remains for the two options is the intrinsic value of each. Therefore, the value of the spread is the difference between each option’s intrinsic values at expiration.
Because vertical spreads have an intrinsic value, the term ‘moneyness’ applies to them. Moneyness refers to whether or not and by how much an option, or a vertical spread, may be in the money or out of the money. This is a term used mostly by floor traders, but is still worth noting here.
Vertical Call Spread and Vertical Put Spread Value
Spreads with intrinsic value are considered in the money. How can you identify the value of a vertical call spread or a vertical put spread? Compare the stock price to the strike prices.
Look at any vertical call spread. If the stock price is above the lower strike of the spread, the spread is in the money. In the Feb. 50 – 55-call spread, if the stock is trading at $52.00, then the spread would be in the money by $2. This is because if the spread expired today, the Feb. 50 calls would finish $2.00 in the money. The Feb. 55 calls would finish worthless because they are out of the money. The spread, however, would be in the money with a value of $2.00.
The rule is similar for determining whether or not a spread is out of the money. If the stock price is lower than the lower strike of the spread, the spread is out of the money. Again, looking at the Feb. 50 – 55 call spread, if the spread expired today and the stock price closed at $48.00, (lower than the lower strike) then the spread would be out of the money, thus the spread will be out of the money. If the stock is trading at the same price as the lower strike price, the spread is considered at the money.
For vertical put spreads, a spread is determined to be in the money if the stock price is lower than the higher of the two strikes of the spread. For example, look at the Sept. 40 – 45 put spread. If the stock closes at $42.00 on expiration day, the Feb. 45 put would end up in the money and worth $3.00. The Feb 40 puts would be out of the money creating a $3.00 intrinsic value for the spread. Since the spread has an intrinsic value, it is in the money.
A vertical put spread is out of the money if the stock price is higher than the higher strike of the spread. So, going back to our Sept. 40 – 45 put spread example, if the stock was to close at a price of $46.00 (higher than the higher strike) then both the Sept. 40 and 45 put will expire worthless. Thus the spread will be worthless and out of the money.
A vertical put spread is considered at-the-money when the stock price is equal to the higher strike price.

To get a firm grasp of volatility’s effect on vertical spreads, let us examine three spreads against different implied volatilities while keeping the stock price constant at 67.5. These are the 60 – 65, 65 – 70 and 70 – 75 call spreads.
In-the-Money Vertical Spreads
Looking at the in-the-money spread (June 60 – 65), we see that as volatility increases, the value of the spread decreases. This is because with the increased volatility, the stock has a greater tendency to move. That brings a higher probability of the stock moving to a price where the June 60 – 65 call spread will no longer be in-the-money.
To adjust for higher volatility risk, the spread will have less value. A general rule of thumb is that as volatility increases, the value of an in-the-money vertical spread decreases. Conversely, an in-the-money vertical spread’s value increases as volatility decreases.
At-the-Money Vertical Spreads
A change in volatility has very little effect on the at-the-money vertical spread (June 65 – 70). With the stock price located equidistant from the two strikes, each strike’s volatility component will be very similar. Therefore, both options will increase equally once volatility increases. Being long on one and short on the other, the increase in values will offset each other so the spread’s value will hold fairly constant. When volatility increases or decreases, the value of an at-the-money vertical spread will stay reasonably constant.
Out-of-the-Money Vertical Spreads
The out-of-the-money vertical spread (June 70 – 75) has the opposite effect of the in-the-money vertical spread (June 60 – 65). As volatility increases, the value of the out-of-the-money vertical spread will increase. This is because the increase in volatility assumes that the stock price is more likely to move. Thus, the out-of-the-money vertical call spread is more likely to finish in-the-money.
Because of this spread’s increased potential to finish in-the-money, its value will increase. The spread’s value will decrease if volatility decreases. On the other hand, an out-of-the-money vertical spread’s value increases when volatility increases.
When trying to estimate how your spread will change in price with volatility movement, you must understand how the price and Delta of both of your options – long and short – will act.
It bears repeating again that each spread is different and will act differently depending on where the stock is in relation to the spread and what implied volatility does.
Median Value
An important thing to note is that when volatility increases, spreads crunch to their median value. For example, the median value of a $5.00 spread will be $2.50 while a $10.00 spread will have a $5.00 median value.
Crunching to the median value means that a $5.00 spread with a median value over $2.50 will lose value and head toward the median price. That happens with an increase in volatility. Meanwhile, increased implied volatility will make a spread with a value less than $2.50, increase in value and rise toward median value.
When implied volatility decreases, the value of a $5.00 spread will move away from the median price of $2.50. Therefore, when implied volatility decreases, all the spreads valued above $2.50 will increase in value toward maximum value. Spreads valued below $2.50 will lose value and head toward $0.
The Effect of Time
Time affects the spread differently depending on where the stock is. Look at the QCOM 65 – 70 call spread. Look at the spread’s reaction to the passing of time with the stock price of $65.50.
The chart below shows what the spread’s value does as expiration approaches.
Month Months to Expiration 65 – 70 call spread value Change from prior
Jan. 05 (8 month option) 2.06 N/A
Oct. 04 (5 month option) 2.05 -.01
Jul. 04 (2 month option) 1.92 -.13
June 04 (1 month option) 1.65 -.27
With the stock at $65.50, the spread has $.50 of intrinsic value. Holding the stock price frozen at $65.50 until expiration, the spread would be worth $.50. The table above shows that the spread loses value as time passes and decreases in value toward its $.50 intrinsic value.
Next, look at the 65 – 70 spread’s reaction to the passage of time with the stock priced at $67.50.
Month Months to Expiration 65 – 70 call spread value Change from prior
Jan. 05 (8 month option) 2.33 N/A
Oct. 04 (5 month option) 2.37 +.04
Jul. 04 (2 month option) 2.44 +.07
June 04 (1 month option) 2.47 +.03
With the stock price located directly in between the two strikes, the price of the spread holds at approximately $2.50 throughout the passing of time. Take note that time has very little effect on a vertical spread when the stock price lies halfway (equidistant) between the two strikes of the spread.
Now, set the stock price at $69.50 and observe how the spread reacts over time.
Month Months to Expiration 65 – 70 call spread value Change from prior
Jan. 05 (8 month option) 2.55 N/A
Oct. 04 (5 month option) 2.67 +.12
Jul. 04 (2 month option) 2.96 +.29
June 04 (1 month option) 3.27 +.31
This spread increases in value as time passes. With the stock at $69.50, the spread has an intrinsic value of $4.50. If the stock held at $69.50 until expiration, the spread would be worth $4.50 because that is the amount of the spread’s intrinsic value. As time passes, the spread’s value will increase to finally reach $4.50 at expiration.
In conclusion, time’s effect on a vertical spread is contingent on where the stock is in relation to the spread.

Options Trading Mastery: Spread Prices

Vertical spreads will trade between its minimum and maximum values – zero and the difference between the two strikes. In the case of a vertical call spread, the spread will trade closer to zero when the stock trades closer to or lower than the lower strike price. The spread will trade closer to maximum value when the stock trades closer to or higher than the higher strike price.
Remember, this maximum gain occurs at expiration. Before that, the spread will trade with a premium.
Starting from a stock price of 37.5, a price located directly between the two strikes, (using our example of the August 35 – 40 call spread) we can see the approximate value of the spread is roughly $2.50. This is because the August 35 calls and the August 40 calls are equidistant from the current stock price of $37.50. Being equidistant from the stock, both the August 35 and 40 calls will have almost the same amount of extrinsic value in them.
Thus, the extrinsic values of the two options cancel themselves out since you are long one call and short the other. This would leave each option value consisting of only intrinsic value. With the stock at $37.50, the value of the August 35 – 40 call spread will be $2.50. The August 35 calls will have $2.50 in intrinsic value while the August 40 calls will have $0 in intrinsic value. The difference gives you a spread with a value of $2.50.
A general rule of thumb is if the stock price is located evenly between the two strike prices, the vertical spread should be worth roughly half of the value of the distance between the two strikes. This will be true for vertical put spreads as well as call spreads. From this rule, we can roughly estimate the vertical spread’s price per different stock prices.
For vertical call spreads, if the spread is worth roughly half of the difference between the two strikes with the stock price directly between the two strikes, then as the stock falls to lower strike and beyond, the spreads value will decrease and move closer to $0. Time left until expiration and volatility will dictate how close and how quickly it will approach $0. On the other side, as the stock climbs toward and above the upper strike, the spread’s value will increase toward its maximum value described by the difference between the two strikes.
For vertical put spreads, as the stock price decreases toward the lower strike price, the spread will increase in value and approach its maximum value as defined by the difference between the two strikes. As the stock price increases toward the higher strike, the spread will decrease in value and will approach $0. Again, time until expiration and volatility will determine how quickly and how close the spread will approach $0.
Factors that Affect Spread Pricing
The determination of pricing as described above works in most cases. Be aware that it assumes that the implied volatility in both the 35 and 40 calls is the same. Most often, these two options will have a slightly different implied volatility.
This intra-month difference in implied volatility values through different strikes is known as a vertical volatility skew. The reason the markets run volatility skews is to make sure that out of the money options have enough premium in them to justify the individual option’s risk/reward scenario.
Whatever factors affect the vertical spread, they are contingent on where the stock is in relation to the spread. Changes in implied volatility affect the price of a spread as stated above but the position of the stock in relation to the strikes of the spread is a key determinate of price.
