Part II: Call Option Strategies
Stock Price at Expiration
The break-even point, maximum profit potential, and investment required are
all quite simple computations for a bear spread.
Maximum profit potential== Net credit received
Break-even point== Lower striking price + Amount of credit
Maximum Collateral investment = = risk required
Difference in
striking prices
Credit + Commissions received
In the example above, the net credit received from the sale of the October 30
call at 3 and the purchase of the October 35 call at 1 was two points. This is the max­
imum profit potential. The break-even point is then easily computed as the lower
striking price, 30, plus the amount of the credit, 2, or 32. The risk is equal to the
investment. It is the difference between the striking prices - 5 points - less the net
credit received - 2 points - for a total investment of 3 points plus commissions. Since
this spread involves a call that is not "covered" by a long call with a striking price
equal to or lower than that of the short call, some brokerage firms may require a
higher maintenance requirement per spread than would be required for a bull
spread. Again, since a spread must be done in a margin account, most brokerage
firms require that a minimum amount of equity be in the account as well.
Since this is a credit spread, the investor does not really "spend" any dollars to
establish the spread. The investment is really a reduction in the buying power of the
customer's margin account, but it does not actually require dollars to be spent when
the transaction is initiated.
