Strike Price Selection
Strike price selection for a short diagonal is more difficult because there
are three strikes to price this time. Looking at the current pricing for a
call spread with the short call struck at $55, I get the following selection of
credits:
Upper Call Strike ($)
Call Spread
Net Credit ($)
Percent Total
Risk Percent Total Return
57.50 1.27 17 49
60.00 2.14 33 83
62.50 2.44 50 94
65.00 2.51 67 97
70.00 2.59 100 100
Looking at this, lets say we decide to go with the $55.00/$62.50 call
spread. Doing so, we would receive a net credit of $2.44. Now selecting the
put to purchase is a matter of figuring out the leverage of the position with
which you are comfortable.
