Chapter 29: Introduction to Index Option Produds and Futures
|
||||
The requirement for writing the Dec 170 put naked would be:
|
||||
15% of index
|
||||
Plus put premium
|
||||
Naked put requirement
|
||||
$2,520
|
||||
+ 500
|
||||
$3,020
|
||||
Both of these requirements are above the minimum of 10% of the index.
|
||||
505
|
||||
Options on narrow-based indices are subject to the same naked requirements
|
||||
as stock options: 20% of the index plus the premium less an out-of-the-money
|
||||
amount, with a minimum requirement of 15% of the index.
|
||||
Other margin requirements are similar to those for stock options. For example,
|
||||
if one wanted to write the Dec 170 straddle naked, using the same prices as in the
|
||||
last example, he would have a margin requirement equal to $3,020 - the larger of the
|
||||
put or call requirement, just as he would for stock options. Spread requirements for
|
||||
index options work in exactly the same manner as they do for stock options.
|
||||
LEAPS INDEX OPTIONS
|
||||
LEAPS (Long-term Equity AnticiPation Securities) have been introduced on indices
|
||||
in recent years. Readers not familiar with LEAPS should review the prior chapter on
|
||||
that subject. Since LEAPS have become popular for stocks, it is only logical to think
|
||||
that they would become popular for indices as well.
|
||||
The main problem was that a LEAPS could be a 2-year option on a 350 dollar
|
||||
underlying index. Such an option might cost 20 points. That is too expensive to attract
|
||||
the public customer. Just one option would cost $2,000. Therefore, the exchanges
|
||||
created mini-indices out of OEX, SPX, XMI, and others. These mini-indices that
|
||||
were created are exactly the same as the full indices, except that they are divided by
|
||||
10. This means that instead of having the 2-year put with strike of 350 cost 20 points,
|
||||
a 2-year put with a strike of 35 costs 2 points. This is much more affordable for the
|
||||
individual trader.
|
||||
The following example is of OEX options and the corresponding OAX LEAPS
|
||||
options on the same index. NOTE: OAX is not the universal symbol for this mini
|
||||
index. OEX LEAPS are American exercise, while SPX LEAPS are European. A bro
|
||||
ker should be contacted for symbols, expiration dates, and other details.
|
||||
Example: The following is a sample comparison of prices for OEX and for its com
|
||||
panion index OLX, which is OEX divided by 5. (Originally, OLX was OEX divided by
|
||||
10, but when OEX split 2-for-1 in late 1997, OLX did not split so OLX was thereafter
|
||||
equal to OEX divided by 5).
