Stock Options Pricing and Option Greeks Explained

This article is the first lesson of the Intermediate Options Trading course. It is all about how options are priced and what affects their prices (aka. The Greeks). This is one of the essential lessons for every options trader. It is extremely important to understand options pricing. Therefore, please take your time when going through this lesson and ask questions in the comment section if you have trouble understanding some of the contents. Don’t worry if you don’t understand everything the first time. You can always retake the lesson. Just don’t do the mistake of skipping ahead without understanding everything presented in this lesson. I have tried to explain everything as simple as possible. I have implemented an explanatory video, images, examples, an infographic and more to make the learning experience as ideal as possible.

The contents covered in this lesson aren’t complete basics anymore. To understand everything, you should already have a fundamental understanding of options. If you don’t have this, I recommend taking my Free Options Trading Beginner Course.

Video Lesson:

The Video Lesson below covers almost all the same concepts as the article below. If you prefer watching videos over reading, you should check out the video. But I really recommend watching the video and reading the article for the best learning effect.

How are Options Priced

There is a simple formula for option’s prices: Extrinsic Value + Intrinsic Value = Option’s Price

Intrinsic Value is the amount that an option is in the money (ITM). So the difference between the underlying’s price and the strike price of an ITM option. (Call options are ITM if their strike price is below the underlying’s price and put options are ITM if their strike price is greater than the underlying asset’s price.)

I will try to illustrate this with an example. Let’s say XYZ is trading at $150. If you would buy a call option at the 140 strike price, the call option would have an intrinsic value of $10 ($150 – $140 = $10). However, a call option with a strike price of 155 would have no intrinsic value at all because it isn’t ITM.

A put option at the 140 strike price (still on XYZ) would also have no intrinsic value. The 160 strike put option would have an intrinsic value of $10 ($160 – $150 = $10).

The deeper an option is in the money (ITM), the greater the intrinsic value becomes. Therefore, deep ITM options are more expensive than at the money (ATM) or out of the money (OTM) options. All OTM options have no intrinsic value.

Extrinsic Value is the remaining value of an option. There are multiple factors that affect the extrinsic value of an option. These factors are time left until expiration, the expected volatility (IV) and some less important factors like interest rates. When buying options, more time left until expiration will be an advantage as the underlying asset will have more time to move in the correct direction.

It makes more sense to buy an option with 100 days left until expiration than with 10 days left until expiration if the option requires the underlying asset to move $10 to become profitable. It is just much more likely that the underlying will move this far in 100 days than in 10 days. Therefore, options with more time left until expiration are more expensive. The more time left until expiry, the more expensive options become. The option with 100 days left until expiration can easily be 10x more expensive than the option with 10 days left until expiration. Therefore, choosing an option with more time left isn’t always the best choice.

Another major factor of extrinsic value is implied volatility. The higher the expected volatility becomes, the more expensive options become. This is because an increased volatility creates more opportunities. If an asset is expected to move much more than usual, you can potentially profit more as the asset will potentially move more than it usually does. Options allow you to profit from bigger moves and therefore they become more expensive.

Furthermore, there are other minor factors like interest rates or dividends that affect an option’s value. But these aren’t as relevant as the other factors. A factor like interest rates mainly becomes relevant for very long-term options (aka. LEAPS).

An option’s price can be estimated through advanced formulas like the Black-Scholes model. But this is a topic for a different, more-advanced lesson.

Summed up an option’s price consists of two parts:

1. Intrinsic Value:

  • Intrinsic Value is the amount that an option is ITM

2. Extrinsic Value:

  • Time Left Until Expiration
  • Implied Volatility
  • Other Minor Factors

If intrinsic value wouldn’t exist, option traders could easily make risk-free profits. To make this clear, I will give you a brief example:

Let’s say stock ABC is trading at $50. An option trader chooses to buy a call option with the $40 strike. The option’s extrinsic value is $3. The intrinsic value would be $10 ($50 – $40). Therefore, the option would cost him $13 (*100 = $1300 as a standard option contract controls 100 shares of stock). But if the intrinsic value wouldn’t exist, he would only have to pay $3 (*100 = $300). A call option gives its owner the right to buy the underlying asset at the strike price. Therefore, the buyer of this call option could immediately exercise his option and buy 100 shares of ABC for $40 per share. He could then proceed by selling these shares at $50 per share.

This would leave him with a profit of $700 (-$300 for the option – $4000 when buying the 100 shares for $40 per share + $5000 when selling the 100 shares for $50 per share). These trades could be executed within seconds.

If the option buyer would do the exact same but with paying for the intrinsic value of the option, he would end up with a $300 loss (-$1300 for the option -$4000 when buying the 100 shares for $40 per share + $5000 when selling the 100 shares for $50 per share).

As you can see, intrinsic value prevents arbitrage trades.

Option Greeks Explained

You might have stumbled upon option Greeks before. The Greeks are an essential part of options trading. A common analogy is that option Greeks are as important to trading options as a steering wheel and dashboard is to driving a car. Greeks basically give you an overview of what is going on in your position(s). Some Greeks are more important than others. Nevertheless, you should be aware of almost all of them all the time.

Somehow a common misconception is that Greeks are this overly complicated thing. I will try to break down the Greeks as simple as possible so that you can understand their importance and implement them into your own trading. But keep in mind that I will only cover the basics of these Greeks here.

What are Option Greeks

Option Greeks measure price changes in the option’s price for changes in the relevant factors. One greek for example measures price changes in the option’s price for price changes in the underlying asset. Other factors are time left until expiration, implied volatility… (so basically all the factors that impact an option’s price).


Let’s start with Delta. Delta is a relatively simple but still very important Greek. Delta measures the amount that the option’s price is expected to change for a $1 up-move in the underlying asset. I will try to simplify this with a brief example:

Stock ABC is trading at $200. You bought a call option that currently has a Delta of 40. This would mean that your position (1 long call) would gain $40 for a $1 up-move in ABC. If ABC would move up to $201, your position would gain $40. The same goes for the downside though. If ABC’s price would decrease to $199, the position would lose $40.

Delta is a great indicator of what you want the underlying asset to do. A bullish position usually has a positive Delta and a bearish position normally has a negative Delta. The greater Delta is, the more bullish the position becomes and the more negative Delta is, the more bearish your position becomes. A Delta-value near 0 means that your position is neutral.

Depending on your directional assumption, Delta can give you reasons to adjust your positions. For example, if you expect an asset’s price to go down but you have a position with positive Delta, you may want to adjust the position to fit your directional assumption.

Note that Delta and all the other Greeks aren’t constant. All Greeks change together with their factors.


Gamma measures the rate of change of Delta for a $1 up-move in the underlying asset. Like I just said, Delta isn’t constant. Together with the underlying’s price Delta also changes. Once again, I’ll present this with a short example:

ABC is still trading at $200 and you still have an open long call position. In the previous example, the Delta of this call was 40 meaning that the position changes by $40 for a $1 change in ABC. Let’s say the Gamma for this position is 2. A Gamma of 2 would mean that Delta increases by 2 for a $1 up-move in ABC. The position would still gain $40 if ABC would move up to $201. But now Delta increases by 2 and therefore, Delta now is 42. Another $1 up-move in ABC would lead to a further $42 gain. The overall gain would then be $82.

If ABC’s price decreases by $1, Delta decreases by 2 as Gamma is 2. If ABC drops down to $198, the overall loss would be $78 ($40 + $38). So the loss for every $1 down-move decreases but the gain for every $1 up-move increases for long calls.

As you can see, Gamma can work in your favor or against you. Your losses can increase or decrease for every $1 move in the unwanted direction. The same can be the case for the gains as your gains also can become smaller or greater for each $1 move in the wanted direction.

But note that Gamma isn’t constant either. It also changes together with Delta and the price of the underlying asset.

The next important Greek is Vega. Vega measures the change in the option’s price for a 1% increase in implied volatility (IV). As we learned in an earlier lesson, implied volatility can change. Implied volatility usually increases when prices drop and it normally decreases as prices increase. In times of high implied volatility, options tend to be priced higher than in times of low IV. Therefore, option buyers can profit from a rise in IV, whereas option sellers profit from a decrease in IV. In times of high volatility, option sellers try to profit from decreasing IV.

This is also why Vega is negative for short option positions. A Vega of -20 means that a position would lose $20 for a 1% increase in IV. However, a Vega of -20 also means that a position would gain $20 for a 1% decrease in IV.

Long option positions have positive Vega-values as they profit from rising IV.

Vega and implied volatility should always be considered when trading options. As I just said IV tends to decrease for up-moves in the underlying asset’s price. Therefore, a bearish option position can still gain value even if the underlying asset increases in price if the position has a (very) negative Vega-value. In this case, the decrease in IV would offset the loss from the underlying asset’s move.

As you can see implied volatility can greatly impact your trading and it is very important to know if IV is high or low. Therefore, measures like IV Rank are essential for options traders. IV Rank can give you a very good idea of where IV currently is.

Vega isn’t constant either.


Yet another very important Greek is Theta. Theta is also known as time decay as it measures changes in the option’s price for the passing of 1 day. One main difference between stocks and options is that options expire after a certain time. This can greatly impact an option’s price. Options lose some of their value every day. This is the case because less time means less time for the underlying asset to move in your direction. In other words, less time leads to a decrease in the probability of profit (POP).

Theta or time decay can either be your biggest friend or your biggest enemy. If you are an option seller, Theta is your friend because you want the sold option to lose value so that you can buy it back for less than you initially received for it. If you are an option buyer, however, time decay works against you as your option(s) will lose some of their value every day.

A Theta of 10 would mean that the position gains $1o for the passing of one day if all other factors stay the same. A Theta of -5 would mean that the position loses $5 for the passing of one day if all other factors remain the same.

Theta isn’t constant either. It actually increases the closer an option gets to its expiration date. So an option with 10 days left until expiration loses much more of its value every day than an option with 100 days left until expiration.

Rho measures the change in the option’s price for a 1% change in interest rates. But as interest rates usually don’t change significantly overnight, this Greek isn’t as important as the other Greeks are. As long as you aren’t planning on trading very long-term options (aka. LEAPS), you can disregard this Greek.

The Greeks For Option Strategies

The Greeks of different options influence each other. When you combine different options to create a certain option strategy, the Greeks are added to each other. For example, a strategy with both a short call and a long call (at a higher strike price) will have more neutral Greeks than a single long call. Let’s simplify that with an example:

Stock XYZ is trading at $130. You buy 1 call option at the 140 strike price and sell 1 call option at the 135 strike price. The short call option has a Delta of -40 and the long call option has a Delta of 30. Therefore, the overall strategy has a Delta of -10. In other words, it is a slightly bearish strategy.

Furthermore, the sold call has a Theta of 20 meaning that it will gain $20 for the passing of one day (if everything else stays the same). However, the long call has a Theta of -15, so it loses $15 until the next day. This means that the overall strategy only has a Theta of 5 which means that the strategy will gain $5 every day. As Theta increases the closer the options are to their expiration date, this value will also increase slightly every day (if the remaining factors don’t change significantly).

I hope you get the point. Greeks of different options/positions influence each other. This is the case for all Greeks.

The Image above is a screenshot from my broker platform, Tastyworks. The screenshot shows an open credit spread (1 short call + 1 long call at a higher strike price). As you can see, all the Greeks (except for Rho) are displayed directly next to the Last price. The underlying asset was last traded for $160.13. The strikes of the options are 169 (for the short call) and 172 (for the long call). There are 49 days left until expiration. In the first line, the Greeks for the entire credit spread are displayed. The second row displays the Greeks for the short call only and the last line shows the Greeks for the long call only.

As you can see, the Delta-value of the long call is 16.81. From this, you might think this strategy is a bullish strategy. But as soon as you see the Delta-value of the short call, you should realize that the strategy actually is slightly bearish. It would profit from the underlying asset moving down. To be exact, the credit spread would earn about $7.5 for every $1 down-move in the underlying asset.

The credit spread also profits from time passing by and from a decrease in implied volatility. A 1% drop in IV would create a $3.74 gain in this spread (if everything else stays the same). The credit spread also earns almost $1 for the passage of one day (if the other factors remain the same). The short call even gains almost $4 every day. But this gain isn’t seen in the credit spread because the long call loses ca. $3 every day. (As there still is quite some time left until expiration, Theta is relatively low. Theta will increase the closer this spread will get to expiration.)

Side Note

The standard lot size for an option is 100. This means even though options often are quoted as if they were sold in singles, they aren’t. Usually, 1 option contract controls 100 shares of stock. Therefore, you often have to multiply the quoted option’s price by 100. If an option quote is $1.50, you have to multiply it by 100 to get the actual price of one option contract ($1.50*100 = $150).

The same goes for the Greeks. For some brokers, you will have to multiply the Greeks by 100. For example, some brokers tell you that the Delta for your position is 0.4 instead of 40. A Delta of 0.4 would mean that the option’s price increases by $0.4 for a $1 increase in the underlying asset. So if the option initially was worth $5, it would be worth $5.4 after a $1 increase in the underlying asset. Nevertheless, you still would have to pay $540 to purchase that option as the standard lot size is 100 and not 1 ($5.4*100 = $540).

Make sure to find out how your broker platform quotes the Greeks as there is a big difference between these two methods.

My broker platform, Tastyworks shows the Greeks like I explained them originally.


Option prices are affected by a variety of different factors. The Greeks measure price changes in the option’s price for changes in these different factors. It is very important to be aware of the Greeks when trading options (except for Rho). Greeks can give you a very good idea of how your position is doing and if/how you should adjust your positions.

To recap the basics of how options are priced, I created the following infographic. Hopefully, it helps with the understanding of the discussed concepts:

(If you want to use this infographic, go ahead. Just make sure to link back to this article.)

Free Cheat Sheet

To see how certain option positions are affected by the different Greeks, I have created a table at the bottom of the page. It shows the impact of the Greeks on different positions.

A plus means that an increase in this factor will work in your favor, whereby a minus means that this factor is unfavorable to your position.
For example, Delta is positive for long calls meaning that the position will gain value for an increase in the underlying’s price. In other words, a long call is a bullish strategy.

A positive Vega means that the position will gain value from an increase in implied volatility. A negative Vega indicates that the position will gain value from a decrease and lose value for an increase in implied volatility.

A short put has a positive Theta meaning that time decay works in favor of this position…

I hope you understand how this table works and how it can help you understand the Greeks. The Greeks are something you will come across a lot in the future

I love this chart at the end and you’re very clear explanations on The Greeks! I’ve been doing some research on options trading, but I have to admit that these “Greek terminologies” are a little intimidating at first.

That, and also most other people who explain them talk like an academic that is really hard to understand. I never really got Vega until I read this explanation on it. So thank you for that!

Also, I had never heard of Rho before, but it seems like it’s not something I really have to be concerned with at the moment since I am not current’y planning on getting into LEAPS.

It looks like you have a deep understanding on options. How long have you been trading them?

Hey Nick, I am so so glad to hear that you are enjoying and learning from my content! To learn more about me and my journey, check out the about me page.

Hi Louis,
Just visited your site dedicated to options trading and I liked it very much.You have very clearly explained how options are priced and option greeks. The chart that you have shown on your site is very helpful to understand more about option trading.I had a lot of doubts about option trading in my mind but I think with this much of study I will be able to make a good amount of profit from option trading.

Wow, very nice site you have there. I haven’t ever traded options but honestly your site looks very well done and informative, and I saw you have a beginner course. Its hard for me to offer any true advice because you definitely seem well educated on options and your site is really well organized.

you have taken an incredibly complicated topic and simplified this the best you can. the use of videos and content to help teach is a great idea. I feel I will rewatch and redo your training a few times as you suggest to ensure it really sinks in. For the first round, I do feel I have a really good understanding. I know I’ll have questions when I come back for the second round after letting this marinate!

So glad to hear that you enjoyed the lesson.

What is the RICE method for injuries?

RICE is an acronym for a type of treatment. Doctors usually recommend this treatment when a person has injured a muscle, tendon, or ligament. These are called soft tissue injuries.

RICE stands for:

  • Rest: Avoiding use of the injured area.
  • Ice: Applying ice packs or bags of frozen vegetables to the area, without them touching the skin directly.
  • Compression: Wrapping the injured area with an elastic bandage to provide support, reduce blood flow, and limit swelling.
  • Elevation: Keeping the area raised above the level of the heart to reduce swelling.

Soft tissue injuries include sprains, strains, and contusions, which are commonly known as bruises.

These injuries are often sports-related. One study reported that sports are responsible for about 50 percent of all musculoskeletal injuries sustained in the United States.

In this article, we describe the correct way to perform RICE and explore why it may be useful.

Share on Pinterest An ice pack may help to numb the affected area, and compression may keep the swelling under control.

The benefits of the RICE method can be explained by stage:

  • Rest: Immobilization prevents further injury and gives the body time to recover.
  • Ice: Cold reduces pain by numbing the affected area.
  • Compression: Pressure keeps swelling under control.
  • Elevation: Keeping the injured body part above the heart reduces swelling and the associated pain and discomfort.

A review of studies conducted in 2020 found that there was not enough data to prove that the RICE method effectively treated sprained ankles.

A 2020 review associated with the Red Cross confirmed that ice was effective immediately after an injury. However, the researchers determined that immobilizing an injured limb may not be helpful. They found no evidence to support elevation. They also found indications that compression may not aid strains or sprains.

However, the RICE treatment method remains widely and frequently recommended for a wide variety of injuries.

It is not always necessary to see a doctor before trying the RICE method.

Following the steps below may help to treat a mild or moderate injury. Begin immediately after an injury, and continue treatment for the next 24–48 hours.

  • Rest the injured area. Avoid moving it and try to keep weight off it. Use splints, braces, canes, or crutches when available.
  • Ice the injury for 20 minutes four to eight times a day. This is especially necessary within the first 3 days. Never allow ice to touch the skin directly.
  • Compression is effective for up to 1 week. Wrap the bandage tightly enough to support the area, without cutting off blood flow.
  • Elevation reduces swelling and bruising by making it more difficult for blood to reach the injury. Experts say it is best to elevate the area for 2–3 hours a day.

Seek medical care if:

  • the injured person cannot put any weight on the area
  • the area is numb or misshapen
  • the injury is recurring

Always exercise caution when returning to everyday activities.

It is most useful for mild to moderate injuries. Doctors usually recommend the RICE method for:

  • sprains
  • strains
  • bruises
  • other soft tissue injuries

People often sustain sprains by tripping, falling, or through sudden twisting motions.

Repeated movements and lifting heavy objects the wrong way can cause strains.

Rice Options Explained

RICE — простой фреймворк, придуманный компанией Intercom. Его можно использовать для оценки проектов и задач, функций и продуктов.

Преимущество инструмента в его простоте и целостности: нам нужно оценить идею по четырем факторам и подставить значения в простую формулу.

RICE — это аббревиатура от четырех факторов, которые предлагается использовать для оценки каждой идеи проекта: охват (Reach), влияние (Impact), уверенность (Confidence) и усилия (Effort).

Мы часто не видим леса за соснами. Делать свой маленький pet project может быть очень увлекательно, но как он повлияет на показатели компании?

Чтобы избежать предвзятости, ответьте на вопрос: сколько пользователей затронут изменения за период?

По возможности, берите цифры из метрик, а не с потолка.


Сайт в среднем посещает 5000 человек в месяц, 50% посетителей заходят с мобильных устройств. Если мы хотим сделать адаптивную вёрстку, охват составит 5000 х 0,5 = 2500 человек в месяц.

Фокусируйтесь на проектах, которые действительно приближают вас к цели, оказывая влияние на ваших пользователей или клиентов.

Компания Intercom разработала пятиуровневую систему оценки для оценки воздействия проекта: 3 = массивное воздействие, 2 = сильное воздействие, 1 = среднее воздействие, 0,5 = слабое воздействие, 0,25 = минимальное воздействие.

Оценить влияние объективно очень сложно, но такой подход всё же лучше невысказанных ощущений.


Ваша цель – увеличить удовлетворение посетителей сайта. Адаптивная вёрстка очень сильно повлияет на посетителей сайта с мобильных устройств. Оценим влияние = 3.

Насколько вы уверены в своих оценках? Оценки, не основанные на метриках, могут ввести вас в заблуждение. Таких заблуждений лучше избегать, оценивая достоверность полученных оценок, где 100% = высокая достоверность, 80% = средняя достоверность, 50% = низкая достоверность. Достоверность ниже 50% — тревожный сигнал. Не принимайтесь за этот проект, если не хотите сыграть в рулетку.


Количество посетителей сайта мы взяли из метрики, влияние оценено на основании опроса пользователей и глубинных интервью, но усилие оценил подрядчик, с которым мы раньше не работали. Общая достоверность средняя, то есть 80%.

Чтобы двигаться быстро, лучше браться за проекты с максимальным охватом и влиянием и минимальными усилиями. Оцените усилия, затрачиваемые всей командой на проект на всех стадиях.

Усилия рассчитываются в человеко-месяцах, где один человеко-месяц — это месяц работы одного члена команды.


Адаптивная вёрстка займет по оценкам около двух недель, то есть значение составит 0,5.

Итак, чтобы быстро подвести итог наших четырех факторов:

Охват: на сколько людей это повлияет? (Оценить в течение определенного периода времени.)

Влияние: насколько это повлияет на каждого человека? (Массивный = 3х, Высокий = 2х, Средний = 1х, Низкий = 0,5х, Минимальный = 0,25х.)

Уверенность: насколько вы уверены в своих оценках? (Высокий = 100%, Средний = 80%, Низкий = 50%.)

Усилия: сколько человеко-месяцев это займет? (Используйте целые числа и минимум полмесяца – не попадайте в сорняки оценки.)

Оценив все факторы, воспользуйтесь этой формулой.
