306 Part Ill: Put Option Strategies
|

A straddle could be sold for 7 points. If the stock were above 38 and below 52 at expi
|
||||
ration, the straddle writer would profit, since the in-the-money option could ht·
|
||||
bought back for less than 7 points in that case, while the out-of-the-money option
|
||||
expires worthless (Table 20-2).

Notice that Figure 20-2 has a shape like a roof. The maximum potential profit
|
||||
point is at the striking price at expiration, and large potential losses exist in either
|
||||
direction if the underlying stock should move too far. The reader may recall that the
|
||||
ratio call writing strategy - buying 100 shares of the underlying stock and selling two
|
||||
calls - has the same profit graph. These two strategies, the naked straddle write and
|
||||
the ratio call write, are equivalent. The two strategies do have some differences, of
|
||||
course, as do all equivalent strategies; but they are similar in that both are highly
|
||||
probabilistic strategies that can be somewhat complex. In addition, both have large
|
||||
potential risks under adverse market conditions or if follow-up strategies are not
|
||||
applied.
|
||||
The investment required for a naked straddle is the greater of the requirement
|
||||
on the call or the put. In general, this means that the margin requirement is equal to
|
||||
the requirement for the in-the-money option in a simple naked write. This require
|
||||
ment is 20% of the stock price plus the in-the-money option premium. The straddle
|
||||
writer should allow enough collateral so that he can take whatever follow-up actions
|
||||
he deems necessary without having to incur a margin call. If he is intending to close
|
||||
out the straddle if the stock should reach the upside break-even point - 52 in the
|
||||
example above - then he should allow enough collateral to finance the position with
