Chapter 33: Mathematical Considerations for Index Products 649
son for this is that the spread will have different outcomes not only based on the price
of one index, but also based on that index's relationship to the other index.
It is possible, for example, that a mildly bullish strategy implemented as an
inter-index spread might actually lose money even if one index rose. This could hap­
pen if the other index performed in a manner that was not desirable. If one could
have his computer "draw" a picture of several different outcomes, he would have a
better idea of the profit potential of his strategy.
Example: Assume a put spread between the ZYX and the ABX indices was estab­
lished. An ABX June 180 put was bought at 3.00 and a ZYX June 175 put was sold at
3.00, when the ZYX was at 175.00 and the ABX Index was at 178.00. This spread will
obviously have different outcomes if the prices of the ZYX and the ABX move in dra­
matically different patterns.
On the surface, this would appear to be a bearish position - long a put at a high­
er strike and short a put at a lower strike. However, the position could make money
even in a rising market if the indices move appropriately: If, at expiration, the ZYX
and ABX are both at 179.00, for example, then the short option expires worthless and
the long option is still worth 1.00. This would mean that a 1-point profit, or $500, was
made in the spread ($1,500 profit on the short ZYX puts less a $1,000 loss on the one
ABX put).
Conversely, a downward movement doesn't guarantee profits either. If the ZYX
falls to 170.00 while the ABX declines to 175.00, then both puts would be worth 5 at
expiration and there would be no gain or loss in the spread.
What the strategist needs in order to better understand his position is a "sliding scale"
picture. That is, most follow-up pictures give the outcome (say, at expiration) of the
position at various stock or index prices. That is still needed: One would want to see
the outcome for ZYX prices of, say, 165 up to 185 in the example. However, in this
spread something else is needed: The outcome should also take into account how the
ZYX matches up with the ABX. Thus, one might need three (or more) tables of out­
comes, each of which depicts the results as ZYX ranges from 165 up to 185 at expi­
ration. One might first show how the results would look if ZYX were, say, 5 points
below ABX; then another table would show ZYX and ABX unchanged from their
original relationship (a 3-point differential); finally, another table would show the
results if ZYX and ABX were equal at expiration.
If the relationship between the two indices were at 3 points at expiration, such
a table might look like this:
