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.

When purchasing a time spread, the investor should pay attention not only to the movement of the stock price but especially to the movement of volatility.
Volatility plays a very large roll in the price of a time spread and, as we have stated, the time spread is an excellent way to take advantage of anticipated volatility movements in a hedged fashion.
Since the time spread is composed of two options, the investor should understand the role of volatility in options as well as in time spreads. Let’s start with option volatility.
An option’s volatility component is measured by a term called vega. Vega, one of the components of the pricing model, measures how much an option’s price will change with a one point (or tick) change in implied volatility. Based on present data, the pricing model assigns the vega for each option at different strikes, different months and different prices of the stock.
Vega is always given in dollars per one tick volatility change. If an option is worth $1.00 at a 35 implied volatility and it has a .05 vega, then the option will be worth $1.05 if implied volatility were to increase to 36 (up one tick) and $.95 if the implied volatility were to decrease to 34 (down one tick). Remember, vega is given in dollars per one tick volatility change.
As we continue to discuss vega, keep these facts in mind
1. Vega measures how much an option price will change as volatility changes.
2. Vega increases as you look at future months and decreases as you approach expiration.
3. Vega is highest in the at the money options.
4. Vega is a strike-based number – it applies whether the strike is a call or a put.
5. Vega increases as volatility increases and decreases as volatility decreases.
It is important to note that an option’s volatility sensitivity increases with more time to expiration. That is, further out-month options have higher vegas than the vegas of the near term options. The further out you go over time, the higher the vegas become.
Although increasing, they do not progress in a linear manner. When you check the same strike price out over future months you will notice that vega values increase as you move out over future months.
The at-the-money strike in any month will have the highest vega. As you move away from the at-the-money strike, in either direction, the vega values decrease and continue to decrease the further away you get from the at-the-money strike.
Remember, vega (an option’s volatility component value) is highest in at-the-money, out-month options. Vega decreases the closer you get to expiration and the further away you move from the at-the-money strike. The chart below shows vega values for QCOM options.
As you look at the chart observe the important elements: the stock price is constant at 68.5; volatility is constant at 40; time progresses from June to January; and finally, the strike price changes from 50 through 80. Notice the increasing pattern as you go out over time. Also notice how the value decreases as you move away from the at-the-money strike.
Another important fact about vega is that it is a strike-based number. That means that the vega number does not differentiate between put and call. Vega tells the volatility sensitivity of the strike regardless of whether you are looking at puts or calls. So, the vega number of a call and its corresponding put are identical.

We are going to put together an imaginary spread scenario and set it in real life events. Consider that, in October, you begin to hear about IJK stock. It looks interesting, so you use a variety of sources to learn about it. (News, charts, outside analysts, Internet research, etc.) From your investigations, you decide that this stock is poised for a strong upward move and you would like to take advantage of it. Each share is $50.00 and you question whether you want to put out the capital for enough shares to make the trade worthwhile.
Now is the time to investigate IJK spreads. Since you are bullish on the stock, you look into the bullish plays of the call spreads and the put spreads. You check the pricing of both since you know that implied volatility and time decay affect your purchase and selling price if you decide to sell out the spread before expiration.
Imagine that you set the spread’s maximum potential gain at $10.00 using our formula. Then you decide that you want to buy a call spread, so you buy 10 IJK Nov. 50 calls and sell 10 IJK Nov 60 calls. This is the Nov. 50-60 spread. The spread’s cost is $3.50, which means you pay $3,500 for the trade. This is inexpensive when you consider that 1,000 shares of IJK stock would have cost you $50,000! You will now wait and follow the stock price of IJK. If you hold the position to expiration, you face the following losses or gains.
If the stock does not move up as you expected and stays at $50 or decreases in value, your spread is worthless and you will lose the $3,500 that you paid for the spread. If the stock begins to move up, you will recoup your investment and move into profits. When the stock has moves up to $3.50, you are at the breakeven point. Every money advance after that represents profit.
At any time until expiration, you can sell out of the spread, but what you receive for the price are influenced by implied volatility and time decay. That will change your profit or loss. If you hold the spread until expiration and your bullish lean proves true, your maximum profit on your $3,500 investment is $6,500.
You paid $3,500 for the spread and received $10,000 at expiration with the stock at $60.00. That represents a $6,500 profit, which is a 186% return. If you had invested $50,000 for 1,000 shares of IJK and at expiration sold the stock for $60,000, your profit is $10,000 for a 20% return.
For many investors the reward/risk scenario of the spread is attractive because investors can limit the capital at risk and the time of risk/reward exposure. The spread also offers protection if your lean is bullish or bearish. Finally, the spread has the potential of a large percentage return on investment.

All stock market multi millionaires must be able to profit under any kind of market conditions. If you are able to profit only when stock markets go up, then you will find it a gargantuan task to ever have any sustainable success, much less become a stock market millionaire.
Yes! It is possible and easy to profit whether stocks are up, down or sideways using option trading. If the ability to trade all kinds of market conditions is the doorway to becoming a stock market millionaire, then option trading would be the very key.
In this article, I will outline some common ways by which you can profit from all kinds of markets by option trading.
Simple Option Strategies for Up Markets
Buy Call Option – You could buy the same number of equivalent stocks for a fraction of the price using call options and profit when the stock goes up. If the stock should crash, you will lose only the small amount you put towards buying the option instead of the whole amount that you would have put towards buying the stock itself.
Sell Naked Put Option – Instead of buying call options, you could sell short put options thereby pocketing the entire amount you made on selling the put options if the stock should go up.
Bull Call Spread – A bull call spread consists of buying call options at the money and selling short out of the money call options of the same month. The benefit of this strategy is that you profit when the stock goes up and profit also when the stock stays sideways!
Simple Option Strategies for Down Markets
Buy Put Option – Instead of shorting stocks and risking a margin call, you could simply buy a put option. Buying a put option is exactly the same as buying call options except that you profit when the stock goes down instead of up.
Sell Naked Call Option – Instead of buying put options, you could sell short call options thereby pocketing the entire amount you made on selling the put options if the stock should go down.
Bear Put Spread – A bear put spread consists of buying put options at the money and selling short out of the money put options of the same month. The benefit of this strategy is that you profit when the stock goes down and profit also when the stock stays sideways!
Simple Option Strategies for UP or DOWN Markets
Straddle – A straddle consist of buying a call option and a put option at the same strike price on the same stock. This strategy allows you to profit whether the stock moves up or down and is excellent when you are certain that a stock will move greatly soon but isn’t sure which direction that may be.
Strangle – Similar concept to a straddle but buys out of the money call option and put option instead of at the money ones in order to reduce the cost of the position.
Simple Option Strategies for Sideways Markets.
Covered Call – If you are holding on to a stock that is moving sideways, you could collect “rental” out of it by selling the call option of that stock month after month and pocket the whole amount of the sale should the stock remain sideways.
Short Straddle – Instead of buying call options and put options as described above in a Straddle, you would sell short them instead. In this way, you create an option position which profits when the stock remains sideways.
Are you amazed now at how easy it is to profit in any kind of market conditions by option trading? These are only very few of the many more option trading strategies that you can use to your specific portfolio needs.

Let’s put together what we’ve been talking about, develop an imaginary spread scenario and set it in real life events.
In October, let’s say that you begin to hear about IJK stock. It looks interesting, so you then use a variety of sources to learn about IJK: news, charts, outside analysts, internet research etc. From your investigations you decide that this stock is poised for a strong upward move and you’d like to take advantage of it.
However, each share is $50.00 and you question whether you want to put out the capital for enough shares to make the trade worthwhile.
Now is the time to investigate IJK spreads. Since you are bullish on the stock, you investigate the bullish plays of the call spreads and the put spreads. You check the pricing of both since you are aware that implied volatility and time decay will affect both your purchase price and your selling price if you decide to sell out the spread before expiration.
Let’s say that you set the spread’s maximum potential gain at $10.00 using our formula. Then you decide you want to buy a call spread, so you buy 10 IJK Nov. 50 calls and sell 10 IJK Nov 60 calls. The spread is called Nov. 50-60. The spread’s cost is $3.50, which means you pay $3500 for the trade, inexpensive when you consider that to purchase 1000 shares of IJK stock would have cost you $50,000! Now, you wait and follow the stock price of IJK. If you hold the position to expiration, you face the following losses or gains.
First, if the stock does not move up as you expected and stays at $50 or decreases in value, your spread is worthless and you lose the $3500 that you paid for the spread. Second, if the stock begins to move up, you first recoup your investment and then move into profits. After the stock has moved up $3.50 you are at the breakeven point. Every money advance after that represents profit.
The chart below represents the spread’s losses and gains and your total profit
This chart is based on stock prices at expiration Friday in November. Until then the spread’s value fluctuates between $0 and its maximum (the difference between strike prices) of $10.00
At any time until expiration, you can sell out of the spread but what you receive for the price may be influenced by implied volatility and time decay and that will change your profit or loss. If you hold the spread until expiration and your bullish lean proves true, your maximum profit on your $3500 investment is $6500.
You paid $3500 for the spread and received $10,000 at expiration with the stock at $60.00. That represents a $6500 profit which is a 186% return.
If you had invested $50,000 for 1000 shares of IJK and at expiration sold the stock for $60,000, your profit is $10,000 for a 20% return.
For many investors the reward/risk scenario of the spread is attractive because investors can limit the capital at risk and the time of risk/reward exposure. The spread also offers protection if your lean is bullish or bearish. Finally, the spread has the potential of a large percentage return on investment.

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.

The recent stock market crisis (2008) took the stock market down by more than 30% in less than a year. This has a lot of traders thinking that big money can be made simply by buying put options on stocks that will move down with the market, especially high beta ones. Nothing can be further from the truth. Most amateur options traders who did that either failed to make any money, make very little money or outright lose money even though the stock moved down a lot as predicted. Why is that so?
Volatile market conditions are especially bad for buying stock options due to 2 reasons. Firstly, the extreme volatility resulted in extremely high implied volatility which increases the extrinsic value of options dramatically, depressing its profitability. Secondly, extreme volatility leads to extreme speculation which encourages market makers to open up the bid ask spread to an unreasonably wide level in order to fill their own pockets.
Extrinsic value is the price one pays to the seller of stock options in order to justify the risk undertaken by the seller for giving such a right to the buyer. This price is arrived at in theory by options pricing models such as the Black-Scholes model. Extrinsic value directly affects the profitability of the options as the higher the extrinsic value of an option, the more the underlying stock needs to move in order to breakeven or profit. For example, if two options based on the same underlying stock, the same strike price and expiration month have different extrinsic values (of course this cannot be the case in reality), the option with the higher extrinsic value will make lesser money in profit than the option with the lower extrinsic value when the underlying stock moves by the same amount when held to expiration.
Extrinsic value is affected mainly by the level of implied volatility of the underlying stock. If the underlying stock is expected to make big moves, implied volatility goes up and the extrinsic values of its options go up as well. In times of extreme market volatility, extrinsic values go up dramatically across the board, depressing the profitability of options. In fact, one could end up losing more money than usual if the stock does not move according to expectations due to the higher extrinsic value paid. This is why a lot of amateur options traders who simply bought put options recently failed to make much money or any at all. This situation is made even worse by the wide bid ask spreads provided by the market makers.
Market makers are whom options traders really trade options with. When you buy an option, you are really buying directly from market makers who hold an inventory of those options and when you sell options, you are really selling back to these market makers who want to maintain an inventory of those options. Market makers buy and sell options in the exchange, ensuring the liquidity of all options contracts and profit primarily from the bid ask spread that they provide, buying at the bid and selling at the ask. They function exactly like used car dealers, buying at lower prices and selling at higher prices. Typically, the more actively traded the options are, the closer the bid ask spread tend to be due to competition between market makers, however, in times of extreme volatility where there are a lot more buying and selling on panic and more than enough business to go around for all market makers, they usually open up the bid ask spread in order to make even more profits. That is why we saw unusually wide bid ask spreads in this recent crisis. Wider bid ask spreads result in larger upfront losses which again depress the already depressed profitability of stock options due to the higher extrinsic values.
The higher extrinsic value and wider bid ask spread makes profiting from simple stock options buying extremely difficult and are the main reasons why amateur options traders fail to make money buying put options during the recent stock market crisis. Conversely, writing options are an extremely profitable way to trade options during a volatile market where extrinsic values are high. Naked writes and Credit Spreads are really the way to go in a volatile market condition and are what most beginner options traders do not know about. Selling options instead of buying them turns the table around and creates an extremely profitable position during times of high extrinsic value.

The seller of a time spread buys the nearer month option and sells the outer-month option in a one-to-one ratio. To profit from the sale of the time spread, the seller must look for two things.
The first is a decrease in implied volatility. As volatility decreases, the out-month option (which the seller is short) loses money faster than the near month option (which the seller is long) because of the higher Vega in the out month option. This will cause the spread to contract or lose value and will be profitable for the time spread seller.
The second thing a seller should look for is a movement in stock. A time spread is at its widest, most expensive point when it is at-the-money. A movement away from the strike in either direction decreases the value of the spread. As long as the stock moves in either direction away from the strike, the seller’s position could be profitable if time decay does not outperform the stock movement.
Time, unfortunately, never works in favor of the time-spread seller. The nearer month option (which the seller is long) naturally decays at a faster rate than does the out-month option (which the seller is short). These differing decay rates cause the spread to expand and increase in value, which produces a loss for the time spread seller.
Increases in implied volatility are also detrimental to the potential profits of the time- spread seller. When implied volatility increases, the out month option (which the seller is short) increases in value faster than the near month option (which the seller is long). This is due to the out month option’s higher Vega which creates an expansion in the spread and increases its value resulting in a negative for the spread seller.
The seller, in theory, has an unlimited loss potential. The maximum loss potential is not so much determined by the stock price movement but by the movement in implied volatility. As the seller, you will be long the front month call and short the out-month call.
The out month call will be more sensitive to movements in implied volatility due to a higher Vega or volatility sensitivity component. If implied volatility increases, then the seller’s short, out month option will increase more in value than will the seller’s long, front month option. This will cause the spread to widen or increase in value – a negative for the seller.
The second risk is that the option the seller is long is going to expire approximately 30 days prior to the option the seller is short. If volatility does not decrease or the stock does not move away from the strike significantly before the seller’s long option expires, (s)he will be left short a naked or un-hedged option and a loss on the position.
If the seller can wait out the position, the lost extrinsic value of the short option is retainable. This option also has a limited life and must shed its extrinsic value, no matter how much, by its expiration. The problem facing the seller is that the position is no longer hedged and the seller now faces unlimited risk.
Once the long option expires leaving the seller short a now naked call, stock price movement in the wrong direction is a substantial risk and under the circumstances described above, a big problem.
While the seller can wait out an implied volatility movement that created an increase in extrinsic value, they will probably not be able to wait out a large, negative stock movement creating an increase in intrinsic value. In that case, the seller must take action to prevent substantial losses once the front month expires. Attention to the implied volatility in the farther out option when the nearer month option expires can save the seller from a large loss.

When purchasing a time spread, the investor should pay attention to not only the movement of the stock price, but also the movement of volatility. It plays a very large roll in the price of a time spread, which is an excellent way to take advantage of anticipated volatility movements in a hedged fashion.
Option Volatility
Since the time spread is composed of two options, the investor should understand the role of volatility in options as well as in time spreads. Let us start with option volatility.
We measure an option’s volatility component by a term called Vega. Vega, one of the components of the pricing model, measures how much an option’s price will change with a one-point (or tick) change in implied volatility. Based on present data, the pricing model assigns the Vega for each option at different strikes, different months and different prices of the stock.
Vega is always given in dollars per one tick volatility change. If an option is worth $1.00 at a 35 implied volatility and it has a .05 Vega, then the option will be worth $1.05 if implied volatility were to increase to 36 (up one tick) and $.95 if the implied volatility were to decrease to 34 (down one tick).
Keep these facts in mind as we continue to discuss Vega:
1. Vega measures how much an option price will change as volatility changes.
2. Vega increases as you look at future months and decreases as you approach expiration.
3. Vega is highest in the at-the-money options.
4. Vega is a strike-based number. It applies whether the strike is a call or a put.
5. Vega increases as volatility increases and decreases as volatility decreases.
It is important to note that an option’s volatility sensitivity increases with more time to expiration. Further out-month options have higher Vegas than the Vegas of the near term options. The further out you go over time, the higher the Vegas become. Although increasing, they do not progress in a linear manner. When you check the same strike price out over future months you will notice that Vega values increase as you move out over future months.
The at-the-money strike in any month will have the highest Vega. As you move away from the at-the-money strike in either direction, the Vega values decrease and continue to decrease the further away you get from the at-the-money strike. Remember, Vega (an option’s volatility component value) is highest in at-the-money, out-month options. Vega decreases the closer you get to expiration and the further away you move from the at-the-money strike.
The chart below shows Vega values for QCOM options. Observe the important elements. The stock price is constant at 68.5. Volatility is constant at 40. Time progresses from June to January. Finally, the strike price changes from 50 through 80. Notice the increasing pattern as you go out over time and how the value decreases as you move away from the at-the-money strike.

Another important fact about Vega is that it is a strike-based number. This means that the Vega number does not differentiate between put and call. Vega tells the volatility sensitivity of the strike regardless of whether you are looking at puts or calls. Therefore, the Vega number of a call and its corresponding put are identical.
The chart below shows the Vega values for calls and the corresponding puts. As you can see, these values match up in every instance.

Vega can also calculate how much a specific option’s price will change with a movement in implied volatility. You simply count how many volatility ticks implied volatility has moved. Multiply that number times the Vega and either add it (if volatility increased) to the option’s present value or subtract it (if volatility decreased) from the option’s present value to obtain the option’s new value under the new volatility assumption. The calculation works on individual options and can analyze the value of the time spread.
Apply Vega to Time Spreads
Now, let us apply the concepts of Vega to the Time Spread. When you apply the Vega concept to time spreads, you observe that as implied volatility increases, the value of the time spread increases. This is because the out-month option, with the higher Vega will increase more than the closer month option with the lower Vega. That widens or increases the spread.
The chart below shows a time spread and its reaction to increasing volatility. Each time that implied volatility increases, the value of the time spreads increase. This increase would naturally favor the buyer.

65.5 50 1.77 3.41
65.5 60 2.11 4.05
65.5 70 2.49 4.60
If an investor bought the time spread at low volatility and within a few weeks volatility had increased and pushed the spread price higher, the investor could sell the spread at a profit even before expiration.
Of course, the Vega can also demonstrate the opposing effect. As implied volatility decreases, the spread tightens or decreases in value. As volatility comes down, the out-month option with its higher Vega will lose value more quickly than will the nearer month option with its lower Vega. In the chart below, you will see how decreasing volatility affects the time spread’s value.

Glance back to Charts 4 and 5. Take note that the stock price is constant. The changes in the price of the spreads are due to the change in volatility.
We discussed how to use Vega to calculate an option’s price when volatility changes. The same calculation method works for time spreads but the calculation is slightly more difficult.

The seller of a time spread buys the nearer month option and sells the outer-month option in a one-to-one ratio. To profit from the sale of the time spread, the seller must look for two things.
The first is a decrease in implied volatility. As volatility decreases, the out-month option (which the seller is short) loses money faster than the near month option (which the seller is long) because of the higher Vega in the out month option. This will cause the spread to contract or lose value and will be profitable for the time spread seller.
The second thing a seller should look for is a movement in stock. A time spread is at its widest, most expensive point when it is at-the-money. A movement away from the strike in either direction decreases the value of the spread. As long as the stock moves in either direction away from the strike, the seller’s position could be profitable if time decay does not outperform the stock movement.
Time, unfortunately, never works in favor of the time-spread seller. The nearer month option (which the seller is long) naturally decays at a faster rate than does the out-month option (which the seller is short). These differing decay rates cause the spread to expand and increase in value, which produces a loss for the time spread seller.
Increases in implied volatility are also detrimental to the potential profits of the time- spread seller. When implied volatility increases, the out month option (which the seller is short) increases in value faster than the near month option (which the seller is long). This is due to the out month option’s higher Vega which creates an expansion in the spread and increases its value resulting in a negative for the spread seller.
The seller, in theory, has an unlimited loss potential. The maximum loss potential is not so much determined by the stock price movement but by the movement in implied volatility. As the seller, you will be long the front month call and short the out-month call.
The out month call will be more sensitive to movements in implied volatility due to a higher Vega or volatility sensitivity component. If implied volatility increases, then the seller’s short, out month option will increase more in value than will the seller’s long, front month option. This will cause the spread to widen or increase in value – a negative for the seller.
The second risk is that the option the seller is long is going to expire approximately 30 days prior to the option the seller is short. If volatility does not decrease or the stock does not move away from the strike significantly before the seller’s long option expires, (s)he will be left short a naked or un-hedged option and a loss on the position.
If the seller can wait out the position, the lost extrinsic value of the short option is retainable. This option also has a limited life and must shed its extrinsic value, no matter how much, by its expiration. The problem facing the seller is that the position is no longer hedged and the seller now faces unlimited risk.
Once the long option expires leaving the seller short a now naked call, stock price movement in the wrong direction is a substantial risk and under the circumstances described above, a big problem.
While the seller can wait out an implied volatility movement that created an increase in extrinsic value, they will probably not be able to wait out a large, negative stock movement creating an increase in intrinsic value. In that case, the seller must take action to prevent substantial losses once the front month expires. Attention to the implied volatility in the farther out option when the nearer month option expires can save the seller from a large loss.
