312 Part Ill: Put Optian Strategies

3½ points. Thus, if XYZ should reverse direction and be within 3½ points of the
|
||||
striking price - that is, anywhere below 48½ - at expiration, the position will pro
|
||||
duce a profit. In fact, if XYZ should be below 45 at expiration, the entire bear
|
||||
spread will expire worthless and the strategist will have made a 3½-point profit.
|
||||
Finally, this repurchase of the put releases the margin requirement for the naked
|
||||
put, and will generally free up excess funds so that a new straddle position can be
|
||||
established in another stock while the low-requirement bear spread remains in
|
||||
place.
|
||||
In summary, this type of follow-up action is broader in purpose than any of the
|
||||
simpler buy-back strategies described earlier. It will limit the writer's loss, but not
|
||||
prevent him from making a profit. Moreover, he may be able to release enough mar
|
||||
gin to be able to establish a new position in another stock by buying in the uncov
|
||||
ered puts at a fractional price. This would prevent him from tying up his money
|
||||
completely while waiting for the original straddle to reach its expiration date. The
|
||||
same type of strategy also works in a downward market. If the stock falls after the
|
||||
straddle is written, one can buy the put at the next lower strike to limit the down
|
||||
side risk, while still allowing for profit potential if the stock rises back to the striking
|
||||
price.
|
||||
EQUIVALENT STOCK POSITION FOLLOW-UP
|
||||
Since there are so many follow-up strategies that can be used with the short straddle,
|
||||
the one method that summarizes the situation best is again the equivalent stock posi
|
||||
tion (ESP). Recall that the ESP of an option position is the multiple of the quantity
|
||||
times the delta times the shares per option. The quantity is a negative number if it is
|
||||
referring to a short position. Using the above scenario, an example of the ESP
|
||||
method follows:
|
||||
Example: As before, assume that the straddle was originally sold for 7 points, but the
|
||||
stock rallied. The following prices and deltas exist:
|
||||
XYZ common, 50;
|
||||
XYZ Jan 45 call, 7; delta, .90;
|
||||
XYZ Jan 45 put, l; delta, - .10; and
|
||||
XYZ Jan 50 call, 3; delta, .60.
|
||||
Assume that 8 straddles were sold initially and that each option is for 100 shares of
|
||||
XYZ. The ESP of these 8 short straddles can then be computed:
