Call Option

5 stars based on 49 reviews

As with any of the previous modules in Varsity, we will again make the same old assumption that you are new to options and therefore know nothing about options. For this reason we will start from scratch and slowly ramp up as we proceed.

Let us start with running through some basic background information. The options market makes up for a significant part of the derivative market, particularly in India. Internationally, the option market has been around for a while now, here is a quick background on the same —.

Clearly the international markets have evolved a great deal since the OTC days. However in India from the time of inception, the options market was facilitated by the exchanges. The badla system no longer exists, it has become obsolete. Here is a quick recap of the meaning call option trading example india of the Indian derivative markets —.

Though the options market has been around sincethe real liquidity in the Indian index options was seen only in ! I remember trading options around that time, the spreads were high and getting fills was a big deal.

However inthe Ambani brothers formally split up and their respective companies were listed as separate entities, thereby unlocking the value to the shareholders. In my opinion this particular corporate event triggered vibrancy in the Indian markets, creating some serious liquidity. However if you were to compare the liquidity in Indian stock options with the international markets, we still have a long way to catch up.

There are two types of options — The Call option and the Put option. You can be a buyer or seller of these options. In fact the best way to understand the call option is to first deal with a tangible real world example, once we understand this example we meaning call option trading example india extrapolate the same to stock markets.

Consider this situation; there are two good friends, Ajay and Venu. Ajay is actively evaluating an opportunity to buy 1 acre of land that Venu owns. The land is valued at Rs. Ajay has been informed that in the next 6 months, a new highway project is likely to meaning call option trading example india sanctioned near the land that Venu owns. If the highway indeed comes up, the valuation of the land is bound to increase and therefore Ajay would benefit from the investment he would make today.

So what should Ajay do? Clearly this situation has put Ajay in a dilemma as he is uncertain whether to buy the land from Venu or not. While Ajay is muddled in this thought, Venu is quite clear about selling the land if Ajay is willing to buy. Ajay wants to play it safe, he thinks through the whole situation and finally proposes a special structured arrangement to Venu, which Ajay believes is a win-win for both of them, the meaning call option trading example india of the arrangement is as follows —.

So what do you think about this special agreement? Who do you think is smarter here — Is it Ajay for proposing such a tricky agreement or Venu for accepting such an agreement? Well, the answer to these questions is not easy to answer, unless you analyze the details of the agreement thoroughly. I would suggest you read through the example carefully it also forms the basis to understand options — Ajay has plotted an extremely clever deal here!

In fact this deal has many faces to it. Now, after initiating this agreement both Ajay and Venu have to wait for the next 6 months to figure out what would actually happen. However irrespective of what happens to the highway, there are only three possible outcomes —. Remember as per the agreement, Ajay has the right to call off the deal at the end of 6 months. Now, with the increase in the land price, do you think Ajay will call off the deal? This means Ajay now enjoys the right to buy a piece of land at Rs.

Clearly Ajay is making a steal deal here. Venu is obligated to sell him the land at a lesser value, simply because he had accepted Rs. Another way to look at this is — For an initial cash commitment of Rs. Venu even though very clearly knows that the value of the land is much higher in the open market, is forced to sell it meaning call option trading example india a much lower price to Ajay. The profit that Ajay makes Rs. It turns out that the highway project was just a rumor, and nothing really is expected to come out of the whole thing.

People are disappointed and hence there is a sudden rush to sell out the land. As a result, the price of the land goes down to Rs. So what do you think Ajay will do now? Clearly it does not make sense to buy the land, hence he would walk away from the deal. Here is the math that explains why it does not make sense to buy the land —.

Remember the sale price is fixed at Rs. Hence if Ajay has to buy the land he has to shell out Rs. Which means he is in effect paying Rs. Clearly this would not make sense to Ajay, since he has the right to call of the deal, he would simply walk away from it and would not buy the land.

However meaning call option trading example india note, as per the agreement Ajay has to let go of Rs. For whatever reasons after 6 months the price stays at Rs.

What do you meaning call option trading example india Ajay will do? Well, he will obviously walk away from the deal and would not buy the land. Why you may ask, well here is the math —. Clearly it does not make sense to buy a piece of land at Rs. Do note, since Ajay has already committed 1lk, he could still buy the land, but ends up paying Rs 1lk extra in this process.

For meaning call option trading example india reason Ajay will call off the deal and in the process let go of the agreement fee of Rs. I hope you have understood this transaction clearly, and if you have then it is good news as through the example you already know meaning call option trading example india the call options work!

But let us meaning call option trading example india hurry to extrapolate this to the stock markets; we will spend some more time with the Ajay-Venu meaning call option trading example india.

I would suggest you be absolutely thorough with this example. If not, please go through it again to understand the dynamics involved. Also, please remember this example, as we will revisit the same on a few occasions in the subsequent chapters. Do note, I will deliberately skip the nitty-gritty of an option trade at this stage. The idea is to understand the bare bone structure of the call option contract.

Assume a stock is trading at Rs. You are meaning call option trading example india a right today to buy the same one month later, at say Rs. Obviously you would, as this means to say that after 1 month even if the share is trading at 85, you can still get to buy it at Rs.

In order to get this right you are required to pay a small amount today, say Rs. If the share price moves above Rs. If the share price stays at or below Rs. All you lose is Rs. After you get into this agreement, there are only three possibilities that can occur. Case 1 — If the stock price meaning call option trading example india up, then it would make sense in exercising your right and buy the stock at Rs.

Case 2 — If the stock price goes down to say Rs. Case 3 — Likewise if the stock stays flat at Rs. This is simple right? If you have understood this, you have essentially understood the core logic of a call option. What remains unexplained is the finer points, all of which we will learn soon. At this stage what you really need to understand is this — For meaning call option trading example india we have discussed so far whenever you expect the price of a stock or any asset for that matter to increase, it always makes sense to buy a call option!

Now that we are through with the various concepts, let us understand options and their associated terms. Hi Sir, Options is like greek and latin to me. Thanks for the analogies.

No, all derivative contracts are routed via the exchanges. You cannot enter into an OTC arrangement, even if you do, it would not be regulated hence quite dangerous. What benefit would Ajay get by calling off the deal before the expiry of 6 months? He will instead wait for the whole 6 months for any chance of the highway project.

My first question Karthik is this: The dropdown value on the NSE website does not contain all months expiries — after 18th May we have 25th June followed by 24th Sept and then 31st Dec What happened to the other months?

For to only June and Dec contracts are available. What happened to the remaining? Saurabh, glad you noticed it! For all stocks options the expiry is very similar to futures. Hence we have current meaning call option trading example india, mid month, and far month contracts. However for Nifty there are several different expiry options. Leaps are good if you have a super long term view on markets. However the problem with leaps in India is that they are not liquid, there are hardly any trading activity here.

Further we looked at four different variants originating from these 2 options —. Think of it this way — if you give a good artist a color palette and canvas he can create some really interesting paintings, similarly a good trader can use these four option variants to create some really good trades. Imagination and intellect is the only requirement for creating these option trades. Hence before we get deeper into options, it is important to have a strong foundation on these four variants of options.

For this reason, we will quickly summarize what we have learnt so far in this module. Arranging the Payoff diagrams in the above fashion helps us understand a few things better. Let me list them for you —. Going by that, buying a call option and buying a put option is called Long Call and Long Put position respectively.

Going by that, selling a call option and selling a put option is also called Short Call and Short Put position respectively. However I think it is best to reiterate a few key points before we make further progress in this module. Buying an option call or put makes sense only when we expect the market to move strongly in a certain direction.

If fact, for the option buyer to be profitable the market should move away from the selected strike price. Selecting the right strike price to trade is a major task; we will learn this at a later stage. For now, here are a few key points that you should remember —. The option sellers call or put are also called the option writers.

Selling an option makes sense when you expect the market to remain flat or below the strike price in case of calls or above strike price in case of put option.

I want you to appreciate the fact that all else equal, markets are slightly favorable to option sellers. This is because, for the option sellers to be profitable the market has to be either flat or move in a certain direction based on the type of option. However for the option buyer to be profitable, the market has to move in a certain direction. Clearly there are two favorable market conditions for the option seller versus one favorable condition for the option buyer. But of course this in itself should not be a reason to sell options.

This means to say that the option writers earn small and steady returns by selling options, but when a disaster happens, they tend to lose a fortune. Well, with this I hope you have developed a strong foundation on how a Call and Put option behaves. Just to give you a heads up, the focus going forward in this module will be on moneyness of an option, premiums, option pricing, option Greeks, and strike selection.

Once we understand these topics we will revisit the call and put option all over again. This information is highlighted in the red box. Below the red box, I have highlighted the price information of the premium. If you notice, the premium of the CE opened at Rs. Moves like this should not surprise you.

These are fairly common to expect in the options world. Assume in this massive swing you managed to capture just 2 points while trading this particular option intraday. This translates to a sweet Rs. In fact this is exactly what happens in the real world. Traders just trade premiums. Hardly any traders hold option contracts until expiry.

Most of the traders are interested in initiating a trade now and squaring it off in a short while intraday or maybe for a few days and capturing the movements in the premium. They do not really wait for the options to expire. These details are marked in the blue box. Below this we can notice the OHLC data, which quite obviously is very interesting. The CE premium opened the day at Rs. However assume you were a seller of the call option intraday and you managed to capture just 2 points again, considering the lot size is , the 2 point capture on the premium translates to Rs.

However by no means I am suggesting that you need not hold until expiry, in fact I do hold options till expiry in certain cases. Generally speaking option sellers tend to hold contracts till expiry rather than option buyers. This is because if you have written an option for Rs.

So having said that the traders prefer to trade just the premiums, you may have a few fundamental questions cropping up in your mind. Why do premiums vary? What is the basis for the change in premium? How can I predict the change in premiums? Who decides what should be the premium price of a particular option? Well, these questions and therefore the answers to these form the crux of option trading. To give you a heads up — the answers to all these questions lies in understanding the 4 forces that simultaneously exerts its influence on options premiums, as a result of which the premiums vary.

Think of this as a ship sailing in the sea. The speed at which the ship sails assume its equivalent to the option premium depends on various forces such as wind speed, sea water density, sea pressure, and the power of the ship. Some forces tend to increase the speed of the ship, while some tend to decrease the speed of the ship.

The ship battles these forces and finally arrives at an optimal sailing speed. Crudely put, some Option Greeks tends to increase the premium, while some try to reduce the premium. Try and imagine this — the Option Greeks influence the option premium however the Option Greeks itself are controlled by the markets. As the markets change on a minute by minute basis, therefore the Option Greeks change and therefore the option premiums! Going forward in this module, we will understand each of these forces and its characteristics.

We will understand how the force gets influenced by the markets and how the Option Greeks further influences the premium. We will do the same in the next chapter.

A quick note here — the topics going forward will get a little complex, although we will try our best to simplify it. While we do that, we would request you to please be thorough with all the concepts we have learnt so far. Thanks a lot for sharing learning material, it is really helpful for beginners like me to understand the concept and strategy of share market..

We are trying out best to complete the modules as fast as we can. European option means the settlement is on expiry day. However, you can just speculate on option premiums…and by virtue of which, you can hold the position for few mins or days.

Also we have potential of unlimited profit in long call or long put and even we can trail stoploss of premiums. Thank you so much for your articles sir.

Cause sitting in front of computer is not possible. Even if we r there we may miss the trade id doing some thing else at the time we are suppose to trade or squareoff the tyrade. Till now it has been very clear and crisp. Thanks for that and hope that further chapters will also come the same way.

We will be discussing SL based on Volatility very soon. Request you to kindly stay tuned till then. We certainly hope to keep the future chapters as easy and lucid as the previous ones have been.

Hi Really nice initiative sir. Hello Sir, if I buy a lot of , call option of strike price at a premium of Rs 2 with a spot price of Now if the price moves to and premium is now at 3 so would be my profit??

Firstly, if the spot moves from to , the premium of the Call option will certainly be more than Rs. Your profits would be —. Hello Sir, I am still confused with the way the profit is calculated. Might be, I am not able to get what u explained and I am really sorry for asking it again. In some of your replies, you mentioned that the profit is calculated as per the difference of spot price and strike price and in some replies u mentioned that it is as per the difference of premium.

In case of 1 lot of shares the profit would be. So which of the above options are correct??? Is there a difference if I am closing my position before expiry or excersize it at expiry? For all practical purposes I would suggest you use the 2nd way of calculating profits…i. Do remember the premium paid for this option is Rs 6. Irrespective of how the spot value changes, the fact that I have paid Rs.

This is the cost that I have incurred in order to buy the Call Option. Please note — the negative sign before the premium paid represents a cash out flow from my trading account. This lead to my confusion. Got your point, see if you are holding the option till expiry you will end up getting the amount equivalent to the intrensic value of the option. I have explained more on this in the recent chapter on Theta…but I would suggest you read up sequentially and not really jump directly to Theta.

The calculation provided by karthik in chapter 3 is for expiry calculation on expirt date.. Hope this clears your doubt.. The minimum value for this option should be STT stands for Security Transaction Tax, which is levied by the Government whenever a person does any transaction on the exchange.
