Option Strategies
Vertical Spread
Now we are getting into more complicated strategies. Up until now we've just been
buying or selling options with a single leg. That is, a transaction with only one
part to it. A transaction can have more than one leg. If all legs of a transaction
cannot be fulfilled, then the transaction does not go through. In the case of a
Vertical Spread, there are four flavours of it:
- Bull Call Spread
- Bear Call Spread
- Bull Put Spread
- Bear Put Spread
You can guess from the name that the spread will include either Call options or Put
options and that you should use it as either a Bullish or Bearish strategy. The term
Spread refers to the dollar difference between the two legs of that transaction.
The examples below will show a $1 spread, but other spreads may be available also.
1. Bull Call Spread
Looking at the diagram above, you can see that there are two legs to this
transaction. Leg 1, you sell a call option and leg 2 you buy a call option. Now
imagine that the market price is somewhere in the middle. A Call
option where the strike price is still above the market price will have no
intrinsic value. A Call option where the market is already trading above
the strike price will have some intrinsic value. So one option is worth
more than the other.
In a Bull Call Spread, you simultaneously sell the higher strike price option
and buy the lower strike price option. Say you receive $1.00 for selling it and
pay $1.20 for buying the other option. When you net the two you end up paying $0.20
per option. That is called a
Net Debit Spread. When you enter your order for this
type of trade, you specify what you want your net debit amount to be. The brokerage
firm will buy and sell the options for you as one single transaction. It will also
figure out how much to pay for the option and how much to accept for the other option
as long as the net amount meets your criteria.
So how do you make money with this? Refer back to the piciture above. In order
for you to make any money, the price of the underlying stock will have to be above
the lower strike price option. And even then you may not recuperate your entire investment.
You get the maximum profit if the market price is above both strike prices. Let look at
some scenarios:

The above tables show what your profit would be as the stock price increases upon expiration. Table
1 clearly shows that the options are worth nothing if the stock price does not go above
the lower strike price option (i.e., $9). You invested a total of $0.20/option. That money
you will lose entirely. On the other end of the extreme, you see table 5. Here the stock price
is so high, yet your profit is only $1.00/option. Why is that? Remember that there are two
legs to the transaction. You have to close them both. In leg 1 you sold an option at strike
price $10. Now you have to close that position by buying it back. At the same in leg 2 you you
have to sell to close that position. So the net will always be $1.00.
So the most money you can make is $80 per option ($100 minus $20 initial investment) in our
example. That's not too bad considering the low risk. You are assured that you won't
lose more than $20 per option no matter how bad the stock performs.
2. Bear Call Spread
This strategy is the opposite of the previous one. In leg 1, you
buy the Call option and leg 2 you sell the Call option. So remember
that when you buy an option far out of the money it is worth less
than one that is not as far out of the money. In this case
leg 1 will be cheaper than leg 2. If you net the legs, you actually
end up receiving some money. Therefore, this is a
Net Credit
Spread. And looking at the picture above, your goal is
to try and keep your net credit. The way it happens is if the price
of the underlying stock goes down. That's why this is called a "Bear"
strategy. Even though you'r dealing in Call options your outlook is bearish.
The most money you can lose is $100 per option. Just like with the Bull Call
Spread you have to understand what happens at expiration. In leg 1, you
will end up buying at the $10 strike price and selling at the market price,
which is much higher. That's a good thing, but remember in leg 2 you sold
a Call option which allows someone else to buy the stock from you at the
low strike price of $9. So if you match up the two transactions you'll
end up with a $1/option loss.
3. Bull Put Spread
Now we're moving away from Call and into Put options. This is a bull
strategy so you'll make money when the stock price goes up (just as in
the Bull Call Spread). The difference is that this is a
Net Credit Spread so your profit is the actual credit you
receive instead of the max profit of $1/Option.
In leg 1 you sold a Put option so that means somebody can sell you their
stock at the strike price of $10. Since this happens when the market price
is lower than the strike price, you'll end up paying too much for the stock.
But that's where leg 2 comes into play. It will limit your losses. Leg 2
allows you to sell your shares at $9/share. You bought that right by buying
a Put option. All you do is match the transactions in red font like you see
in the picture and you can see that the leg 1 buy transaction is matched with
the leg 2 sell transaction. You buy at $10 and sell at $9 for a $1/share loss.
Quick recap: since each option controls 100 shares, it's actually $100 loss per
option.
4. Bear Put Spread
This strategy requires you to have a bearish outlook (as the name suggests) in order
for you to realize any profit. Using the knowledge you have gained from the
earlier examples you should deduct that this is a
Net Debit Spread.
Take a moment to think about why.
Because both legs are Put options you would pay more for the option at the higher
strike price because as the market prices goes lower the $10 strike price option
is worth more. I.e., it is way in the money. As in the previous spreads the max
loss is whatever you invested as your net debit and the max profit is $100/Option.
