Spread trading is a technique that can be used to profit in
bullish, neutral or bearish conditions. It basically functions
to limit risk at the cost of limiting profit as well.
Spread trading is defined as opening a position by buying and
selling the same type of option (ie. Call or Put) at the same
time. For example, if you buy a call option for stock XYZ, and
sell another call option for XYZ, you are in fact spread trading.
By buying one option and selling another, you limit your risk,
since you know the exact difference in either the expiration
date or strike price (or both) between the two options. This
difference is known as the spread, hence the name of this spread
treading technique.
VERTICAL SPREADS
A Vertical Spread is a spread where the 2 options (the one you
bought, and the one you sold) have the same expiration date, but
differ only in strike price. For example, if you bought a $60
June Call option and sold a $70 June Call option, you have
created a Vertical Spread.
Let's assume we have a stock XYZ that's currently priced at $50.
We think the stock will rise. However, we don't think the rise
will be substantial, maybe just a movement of $5.
We then initiate a Vertical Spread on this stock. We Buy a $50
Call option, and Sell a $55 Call option. Let's assume that the
$50 Call has a premium of $1 (since it's just In-The-Money), and
the $55 Call has a premium of $0.25 (since it's $5
Out-Of-The-Money).
So we pay $1 for the $50 Call, and earn $0.25 off the $55 Call,
giving us a total cost of $0.75.
Two things can happen. The stock can either rise, as predicted,
or drop below the current price. Let's look at the 2 scenarios:
Scenario 1: The price has dropped to $45. We have made a mistake
and predicted the wrong price movement. However, since both
Calls are Out-Of-The-Money and will expire worthless, we don't
have to do anything to Close the Position. Our loss would be the
$0.75 we spent on this spread trading exercise.
Scenario 2: The price has risen to $55. The $50 Call is now $5
In-The-Money and has a premium of $6. The $55 Call is now just
In-The-Money and has a premium of $1. We can't just wait till
expiration date, because we sold a Call that's not covered by
stocks we own (ie. a Naked Call). We therefore need to Close our
Position before expiration.
So we need to sell the $50 Call which we bought earlier, and buy
back the $55 Call that we sold earlier. So we sell the $50 Call
for $6, and buy the $55 Call back for $1. This transaction has
earned us $5, resulting in a nett gain of $4.25, taking into
account the $0.75 we spent earlier.
What happens if the price of the stock jumps to $60 instead?
Here's where the - limited risk / limited profit - expression
comes in. At a current price of $60, the $50 Call would be $10
In-The-Money and would have a premium of $11. The $55 Call would
be $5 In-The-Money and would have a premium of $6. Closing the
position will still give us $5, and still give us a nett gain of
$4.25.
Once both Calls are In-The-Money, our profit will always be
limited by the difference between the strike prices of the 2
Calls, minus the amount we paid at the start.
As a general rule, once the stock value goes above the lower
Call (the $50 Call in this example), we start to earn profit.
And when it goes above the higher Call (the $55 Call in this
example), we reach our maximum profit.
So why would we want to perform this Spread?
If we had just done a simple Call option, we would have had to
spend the $1 required to buy the $50 Call. In this spread
trading exercise, we only had to spend $0.75, hence the -
limited risk - expression. So you are risking less, but you will
also profit less, since any price movement beyond the higher
Call will not earn you any more profit. Hence this strategy is
suitable for moderately bullish stocks.
HORIZONTAL SPREADS
We now look a Horizontal Spreads. Horizontal Spreads, otherwise
known as Time Spreads or Calendar Spreads, are spreads where the
strike prices of the 2 options stay the same, but the expiration
dates differ.
To recap: Options have a Time Value associated with them.
Generally, as time progresses, an option's premium loses value.
In addition, the closer you get to expiration date, the faster
the value drops.
This spread takes advantage of this premium decay.
Let's look at an example. Let's say we are now in the middle of
June. We decide to perform a Horizontal Spread on a stock. For a
particular strike price, let's say the August option has a
premium of $4, and the September option has a premium of $4.50.
To initiate a Horizontal Spread, we would Sell the nearer option
(in this case August), and buy the further option (in this case
September). So we earn $4.00 from the sale and spend $4.50 on
the purchase, netting us a $0.50 cost.
Let's fast-forward to the middle of August. The August option is
fast approaching its expiration date, and the premium has
dropped drastically, say down to $1.50. However, the September
option still has another month's room, and the premium is still
holding steady at $3.00.
At this point, we would close the spread position. We buy back
the August option for $1.50, and sell the September option for
$3.00. That gives us a profit of $1.50. When we deduct our
initial cost of $0.50, we are left with a profit of $1.00.
That is basically how a Horizontal Spread works. The same
technique can be used for Puts as well.
