Chapter 30: Stock Index Hedging Strategies 543
|
||||
With the futures having been eliminated as a possibility, the investor must now
|
||||
choose which strike to use. Since he will be selling calls and buying puts, and since
|
||||
either strike allows him to synthetically sell the UVX "future" at 178, he should
|
||||
choose the 180 strike. This should be his choice because the 180 calls are out-of-the
|
||||
money and thus less likely to be the object of an early assignment.
|
||||
HEDGING WITH INDEX PUTS
|
||||
Let us now move on to discuss ways of hedging in which a complete hedge is not
|
||||
established, but rather some risk is taken. The main difference between options and
|
||||
futures is that futures lock in a price, while options lock in a worst-case price (at
|
||||
greater cost) but leave room for further profit potential. To see this, consider a long
|
||||
stock portfolio hedged by short futures. In this case, one eliminates his upside profit
|
||||
potential except for positive tracking error. However, if he buys put options instead,
|
||||
he expends money - thereby incurring a greater cost to himself than if he had used
|
||||
futures - but he still has profit potential if the market rallies.
|
||||
One could hedge a long stock portfolio with options by either buying index puts
|
||||
or selling index calls. Buying the puts is generally the more attractive strategy, espe
|
||||
cially if the puts are cheap. In order to properly establish the hedge, it is not only nec
|
||||
essary to adjust the dollars of stock in accordance with the Beta, but the deltas of the
|
||||
options must be taken into account as well. The following example will demonstrate
|
||||
the use of puts to hedge a portfolio of diverse stocks.
|
||||
Example: Assume that an investor has the same portfolio of three stocks that was
|
||||
used in a previous example: 3,000 GOGO, 5,000 UTIL, and 2,000 OIL. He has
|
||||
become somewhat bearish on the market in general and would like to hedge some of
|
||||
his downside risk. However, he decides to use puts for the hedge just in case there is
|
||||
a further rally in the market.
|
||||
The table from the earlier example is reprinted below, showing the adjusted
|
||||
volatilities and capitalizations for each stock in the portfolio. The total adjusted cap
|
||||
italization of the portfolio is $720,000, as before.
