Call Option Basics
Call Option Basics
There are two types of options – The
Call option and the Put option. You can
be a buyer or seller of these
options. Based on what you
choose to do,
the P&L profile
changes. Of course
we will get into the P&L profile
at a much later stage.
For now, let us understand what “The Call Option” means. 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 will extrapolate the same to stock
markets. So let’s get started.
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.500,000/-. Ajay has
been informed that
in the next
6 months, a new highway
project is likely
to be 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.
However if the ‘highway news’ turns out
to be a rumor- which
means Ajay buys
the land from
Venu today and there
is no highway tomorrow,
then Ajay would
be stuck with a useless
piece of land!
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
details of the arrangement is as follows
–
1.
Ajay pays an upfront
fee of Rs.100,000/- today. Consider
this as a non refundable agree- ment fees that Ajay pays
2.
Against this fees, Venu agrees to sell
the land after 6 months to Ajay
3.
The price of the sale( which is
expected 6 months later) is fixed today at Rs.500,000/-
4.
Because Ajay has paid an upfront
fee, only he can call off the deal at the end of 6 months
(if he wants to that
is), Venu cannot
5.
In the event Ajay calls off the deal at the end of 6 months,
Venu gets to keep the upfront fees
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 under- stand options) – Ajay has plotted an extremely
clever deal here! In fact this deal has many faces to
it.
Let us break down Ajay’s proposal to understand
some details –
➡ By paying an agreement fee of Rs.100,000/-, Ajay
is binding Venu into an obligation. He is forcing Venu to lock the land for him
for the next 6 months
➡ Ajay is fixing the sale price of the land based on today’s price i.e Rs.500,000/- which means irrespective of what the
price would be 6 months
later he gets to buy the
land at to- day’s price.
Do note, he is fixing
a price and
paying an additional Rs.100,000/- today
➡ At the end of the
6 months, if Ajay does
not want to buy the
land he has
the right to say
‘no’ to Venu, but
since Venu has
taken the agreement fee
from Ajay, Venu will
not be in a position to say no to Ajay
➡ The agreement fee is non negotiable,
non refundable
Now, after initiating this agreement both Ajay and Venu have to wait for the next 6 months to figure out what would actually happen. Clearly,
the price of the land
will vary based
on the outcome of the ‘highway project’.
However irrespective of what happens to the highway, there are only
three possible outcomes –
1.
Once the
highway project comes
up, the price
of the land
would go up, say
it shoots up to
Rs.10,00,000/-
2.
The highway
project does not come up, people are disappointed, the land price
col- lapses, say to Rs.300,000/-
3.
Nothing happens,
price stays flat at Rs.500,000/-
I’m
certain there could
be no other possible outcomes
that can occur
apart from the three mentioned above.
We
will now step
into Ajay’s shoes and
think through what
he would do in each
of the above
situa- tions.
Scenario 1 – Price goes up to Rs.10,00,000/-
Since the highway project has come up
as per Ajay’s expectation, the land
price has also in- creased. 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? Not really, because
the dynamics of the sale
are in Ajay’s favor
–
Current Market price of the land = s.10,00,000/- Sale agreement value = Rs.500,000/-
Current Market price of the land = s.10,00,000/- Sale agreement value = Rs.500,000/-
This means Ajay now enjoys the right to buy a piece of
land at Rs.500,000/- when in the open mar- ket
the same land is selling at a much higher value of – Rs.10,00,000/-.
Clearly Ajay is making a steal deal
here. Hence he would go ahead and
demand Venu to sell him the land. Venu is obligated to sell him the land at a lesser value, simply because he had accepted Rs.100,000/- agreement fees
from Ajay 6 months earlier.
So how much money is Ajay making? Well, here is the math – Buy Price = Rs.500,000/-
So how much money is Ajay making? Well, here is the math – Buy Price = Rs.500,000/-
Add: Agreement Fees = Rs.100,000/- (remember this is a
non refundable amount) Total Expense = 500,000 + 100,000 = 600,000/-
Current Market of the land =
Rs.10,00,000/-
Hence his profit is Rs.10,00,000 – Rs.600,000 = Rs.400,000/-
Another way to look at this is – For an initial cash commitment of Rs.100,000/- Ajay is now making
4 times the money! Venu even though very clearly knows that the value of the
land is much higher in the open market, is forced
to sell it at a much lower price to Ajay.
The profit that Ajay makes (Rs.400,000/-) is exactly the notional loss that Venu would incur.
Scenario 2 – Price goes down to Rs.300,000/-
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.300,000/-.
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.500,000/-, 6
months ago. Hence if Ajay has to buy
the land he has to shell out Rs.500,000/- plus he had paid Rs.100,000/- towards
the agreement fees. Which means he is in effect paying Rs.600,000/- to buy a
piece of land worth just Rs.300,000/-. 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
do note, as per the agreement Ajay has to let go
of Rs.100,000/-, which Venu gets to pocket.
Scenario 3 – Price stays at Rs.500,000/-
For whatever reasons after 6 months the price stays at
Rs.500,000/- and does not really change. What do you think 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 –
Cost of Land = Rs.500,000/- Agreement Fee = Rs.100,000/-
Total = Rs.600,000/-
Value of the land in open
market = Rs.500,000/-
Clearly it does not make sense to buy
a piece of land at Rs.600,000/- when it is worth Rs.500,000/-. 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 this reason Ajay will call off the deal and in the
process let go of the agreement fee
of Rs.100,000/- (which Venu obviously pockets).
I hope you have understood this
transaction clearly, and if you have
then it is good news as through the example
you already know how the call options
work! But let us not hurry to extrapo-
late this to the stock
markets; we will
spend some more
time with the
Ajay-Venu transaction.
Here are a few Q&A’s about the transaction
which will throw some more light on the example –
1. Why do you think Ajay took such a bet even though he knows he will lose his 1 lakh if land prices does not
increase or stays flat?
1. Why do you think Ajay took such a bet even though he knows he will lose his 1 lakh if land prices does not
increase or stays flat?
a.
Agreed Ajay would
lose 1 lakh, but the best part is that Ajay knows his maximum loss (which is 1 lakh) before hand. Hence
there are no negative surprises for him. Also, as and when the land prices
increases, so would his profits (and therefore his returns). At Rs.10,00,000/- he would be making
Rs.400,000/- profit on his investment of Rs.100,000/- which is 400
2. Under what circumstances would a position such as Ajay’s make sense?
2. Under what circumstances would a position such as Ajay’s make sense?
a.
Only that scenario when the price
of the land increases
3.
Under what
circumstances would Venu’s position makes sense
a.
Only that
scenario when the
price of the
land decreases of stays flat
4. Why do you think Venu is taking such a big risk? He would lose a lot of money if the land prices increases after 6 months right?
4. Why do you think Venu is taking such a big risk? He would lose a lot of money if the land prices increases after 6 months right?
a.
Well, think
about it. There
are only 3 possible scenarios, out which 2 indeed benefit Venu. Statistically, Venu has
66.66% chances of winning the
bet as opposed
to Ajay’s 33.33% chance
Let us summarize a few important points now –
➡ The payment from Ajay to Venu ensures that
Ajay has a right (remember only he can call off the deal) and Venu has an
obligation (if the situation demands, he has to honor Ajay’s claim)
➡ The outcome of the
agreement at termination (end of 6 months) is determined by the
price of the land. Without
the land, the
agreement has no value
➡ Land is therefore called an
underlying and the agreement is called a derivative
➡ An agreement of this sort is called an
“Options Agreement”
➡ Since Venu
has received the advance from Ajay, Venu is called the ‘agreement seller or
Writer’ and Ajay is called the
‘agreement buyer’
➡ In other words since this agreement is called “an options agreement”, Ajay can be called an Options Buyer and Venu the
Options Seller/writer.
➡ The agreement is entered
after the exchange of 1 lakh,
hence 1 lakh
is the price
of this op-
tion agreement. This is also called
the “Premium” amount
➡ Every variable in the agreement – Area of the land, price and the date of
sale is fixed.
➡ As a thumb rule,
in an options agreement the buyer always
has a right and the seller has an
obligation
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.
Let us now proceed to understand the same example
from the stock market perspective.
– The Call Option
Let us now attempt to extrapolate the same example
in the stock market context
with an intention to understand the ‘Call Option’. Do note, I will deliberately skip the nittygritty 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.67/- today. You are
given a right
today to buy
the same one
month later, at say Rs. 75/-, but only if the share
price on that day is more than Rs. 75, would you buy it?. 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.75!
In
order to get this
right you are
required to pay
a small amount
today, say Rs.5.0/-. If the share price moves above Rs.
75, you can
exercise your right
and buy the
shares at Rs.
75/-. If the
share price stays at or below
Rs. 75/- you
do not exercise your right and
you do not
need to buy
the shares. All you lose is Rs. 5/- in this case. An arrangement of this sort is called
Option Contract, a ‘Call
Option’ to be precise.
After you get into this agreement, there are only three possibilities that can occur. And they are-
1.
The stock
price can go up,
say Rs.85/-
2.
The stock
price can go down,
say Rs.65/-
3.
The stock
price can stay at Rs.75/-
Case 1 –
If the stock
price goes up,
then it would
make sense in exercising your
right and buy
the stock at Rs.75/-.
The P&L would look like this –Price at which stock
is bought = Rs.75
Premium paid = Rs. 5 Expense incurred = Rs.80 Current Market Price = Rs.85
Profit = 85 – 80 = Rs.5/-
Case 2 –
If the stock
price goes down
to say Rs.65/-
obviously it does
not makes sense
to buy it at
Rs.75/- as effectively you would
spending Rs.80/- (75+5)
for a stock that’s
available at Rs.75/-
in the open market.
Case 3 –
Likewise if the
stock stays flat
at Rs.75/- it simply means
you are spending Rs.80/- to buy a stock which is available at
Rs.75/-, hence you would not invoke your right to buy the stock at Rs.75/-.
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 reasons
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 associ- ated terms

Finally before I end this chapter, here is a
formal definition of a call options contract –
“The buyer of the call option has the right,
but not the obligation to buy an agreed quantity
of a par- ticular commodity or financial instrument (the underlying) from
the seller of the option
at a certain time (the
expiration date) for
a certain price
(the strike price).
The seller (or
“writer”) is obligated to sell the commodity or financial instrument should the buyer
so decide. The buyer pays a fee (called
a premium)
for this right”.
