Spread trading is a technique that can be used to profit in bullish, neutral or bearish conditions. It basically functions to limit risk at
cost of limiting profit as well.Spread trading is defined as opening a position by buying and selling
same type of option (ie. Call or Put) at
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
exact difference in either
expiration date or strike price (or both) between
two options. This difference is known as
spread, hence
name of this spread treading technique.
VERTICAL SPREADS
A Vertical Spread is a spread where
2 options (the one you bought, and
one you sold) have
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
stock will rise. However, we don't think
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
$50 Call has a premium of $1 (since it's just In-The-Money), and
$55 Call has a premium of $0.25 (since it's $5 Out-Of-The-Money).
So we pay $1 for
$50 Call, and earn $0.25 off
$55 Call, giving us a total cost of $0.75.
Two things can happen. The stock can either rise, as predicted, or drop below
current price. Let's look at
2 scenarios:
Scenario 1: The price has dropped to $45. We have made a mistake and predicted
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
Position. Our loss would be
$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
$50 Call which we bought earlier, and buy back
$55 Call that we sold earlier. So we sell
$50 Call for $6, and buy
$55 Call back for $1. This transaction has earned us $5, resulting in a nett gain of $4.25, taking into account
$0.75 we spent earlier.
What happens if
price of
stock jumps to $60 instead?
Here's where
- limited risk / limited profit - expression comes in. At a current price of $60,
$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
position will still give us $5, and still give us a nett gain of $4.25.
