350 Part Ill: Put Option Strategies
quently than the case in which both the out-of-the-money put and call expire worth­
less in the previous strategy. Thus, the "calendar combination" strategy will afford the
spreader more opportunities for large profits, and will also never force him to
increase his risk.
OWNING A ✓,,FREE" COMBINATION (THE ""DIAGONAL
BUTTERFLY SPREAD")
The strategies described in the previous sections are established for debits. This
means that even if the near-term options expire worthless, the strategist still has risk.
The long options he then holds could proceed to expire worthless as well, thereby
leaving him with an overall loss equal to his original debit. There is another strategy
involving both put and call options that gives the strategist the opportunity to own a
"free" combination. That is, the profits from the near-term options could equal or
exceed the entire cost of his long-term options.
This strategy consists of selling a near-term straddle and simultaneously pur­
chasing both a longer-term, out-of the-money call and a longer-term, out-of the­
money put. This differs from the protected straddle write previously described in that
the long options have a more distant maturity than do the short options.
Example:
XYZ common: 40
April 35 put:
January 40 straddle:
April 45 call:
If one were to sell the short-term January 40 straddle for 7 points and simultaneous­
ly purchase the out-of-the-money put and call combination -April 35 put and April
45 call - he would establish a credit spread. The credit for the position is 3 points less
commissions, since 7 points are brought in from the straddle sale and 4 points are
paid for the out-of-the-money combination. Note that the position technically con­
sists of a bearish spread in the calls - buy the higher strike and sell the lower strike -
coupled with a bullish spread in the puts - buy the lower strike and sell the higher
strike. The investment required is in the form of collateral since both spreads are
credit spreads, and is equal to the differential in the striking prices, less the net cred­
it received. In this example, then, the investment would be 10 points for the striking
price differential (5 points for the calls and 5 points for the puts) less the 3-point
credit received, for a total collateral requirement of $700, plus commissions.
