Figure 1 below shows a risk/reward graph for a Bear Call
Credit Spread on the Russell 2000 broad-based index (RUT). In order to create this
Bear Call Credit Spread we would open the following two option "legs" shown below:
Buy to open,
RUT 10 contracts, 750 strike, January 2006 Call
Sell to open,
RUT 10 contracts, 740 strike, January 2006 Call
Or
alternatively written as:
Buy 10, RUT
750 Jan 06 Call
Sell 10, RUT
740 Jan 06 Call
Or
Alternatively written as:
10 RUT Jan
740/750 Bear Call Spread

Figure 1
Dissecting the name "bear call credit spread", "bear" denotes that we want the
underlying RUT index to remain below 740, our short Call that we are selling,
or writing. "Call" denotes that the trade is made up of Call options; "Credit"
denotes that we are collecting a credit (premium) and depositing the funds
into our brokerage account upon opening the spread; the credit is the
difference between the 740 Call that we sold, less the 750 call that we
purchased. Because the 740 call is closer to the underlying RUT
index, it's worth more than the 750 call, thus the reason that we end up with a
net credit. "Spread" denotes that we are opening two legs - buying a
call at one strike price, and selling a call at different strike price, but
both in the same expiration month. In this case, we are selling the 740
call (we're getting on the "other side" of the trade, like being
the "house" in a casino) and then we're buying the 750 call for protection to limit our risk. The 740/750 Bear Call Spread is a "10 point" spread
because it has 10 points
between the buy leg and the sell leg.
This risk/reward graph (Figure 1) shows the
underlying Russell 2000 Index
(RUT) on the left, (Y axis on left is the price of the RUT index) and how the
seller of this Bear Call Credit Spread on the right will either make or lose
money. The X axis on the bottom right is the gain or loss on the spread in
dollars.
When this trade expires in 55 days and if the RUT stays below
740, the credit spread would expire worthless for the "buyer", and we the
"seller" of this spread would keep the premium of about $500. If
the RUT starts to climb into the 740 strike, we then would make adjustments,
where these adjustment strategies are covered in the
Learning Center.
For this particular credit spread, we the seller would need to
lock-up $10,000 in maintenance in our brokerage account to open the trade, and
these dollars will be un-locked when the spread is closed. Our total risk
capital to open these 10 credit spreads is the $10k of required maintenance,
less $500 in premium that we collected when first opening the trade, or $9500.
In order to calculate a simple return on investment (ROI) one would divide the
premium collected by the total risk capital, which is 500/9500 = 6%. We generally collect
6% to 10% ROI on 30 day to 45 day credit spreads.
The Bull Put Credit Spread
Figure 2 below shows a Bull Put Credit Spread on the Russell
2000 index (RUT); as discussed above, this type of trade is called a credit
spread because when we as a seller open this type of trade, we will collect
a net credit in premium. When this trade expires, usually in 30 to 45
days, and if the RUT stays
above the 610 strike price, the credit spread will expire worthless for the
buyer and we as the seller will keep the premium collected, which is about $500.
We would open this credit spread by placing the following order:
Sell 10
contracts, RUT 610 strike, January 2006 Put
Buy 10
contracts, RUT 600 strike, January 2006 Put
Or
alternatively:
Sell 10, RUT
610 Jan 06 Put
Buy 10, RUT
600 Jan 06 Put
Or
alternatively:
10 RUT Jan 06
600/610 Bull Put Spread
Maintenance
requirement for this trade is $10,000. ($1k required per spread)
