OPEN INTEREST
What is open interest, and is it something I should be concerned
about in my analysis of an option?
Open interest is the total number of options contracts for a particular
strike that are "open," both long and short. Open interest is
exactly what it sounds like - interest in an option. For the retail trader,
there is really no way to know simply by looking at the open interest who
is on what side of a trade and whether the trade is retail or institutional.
It is also difficult to determine whether a large bump in open interest
was in response to a different trade, in which the purchase or sale of
the contract was simply a hedge meant for insurance purposes, and will
never be "closed" per se. Open interest can be used effectively
in conjunction with other indicators to help you determine the sentiment
of the underlying position. This is more effective in highly liquid stocks
that trade large numbers of contracts. Looking at the distribution of open
interest over a series of strikes in and around the current stock price
should give you some clue as to where a potential support or resistance
level for that issue may be.
MARKET CONDITIONS
Should I adjust my strategy allocation in my trading portfolio
to accommodate certain market conditions? For example, I've noticed that
in the last two months, there has been virtually no direction in the major
indices, but from March to June, it was straight up. What would you suggest?

Like a long-term investor who needs to diversify his portfolios between
stocks, bonds, and cash, an options trader should consider diversifying
capital to different strategies. However, since nothing is written in stone,
I can only really suggest a template to start out with, so you can adjust
it to your own risk tolerance and personality. Generally speaking, the
market moves three ways - up, down, and sideways. In addition, there are
periods of high volatility and low volatility, particularly with options.
Knowing this, but not knowing which combinations of the multiple conditions
will surface next, it would make sense to have a number of different types
of trades on at the same time.
Let's break it down a little. Generally, during periods of low market
volatility when the market is moving up, we can buy calls. If volatility
is high and moving sideways, we might buy calendar spreads. During periods
of low volatility and no direction, straddles are a good strategy to take
advantage of the low price of options with an anticipated market breakout
in either direction. So if all you knew were these strategies, you would
actually have the majority of the market conditions covered - low volatility
directional, high volatility nondirectional, and low volatility nondirectional.
You could use a pie chart-type method to divide the strategies into
three parts, with the largest portion of your trading capital allocated
to the prevailing trend. For example, if the market is bullish and volatility
is low, you may want to put 40% of your capital into buying calls or call
spreads, 30% into high-volatility, nondirectional options (such as calendar
spreads), and 30% into low-volatility, nondirectional options (such as
straddles). This way, you will profit with your calls and straddles if
the current trend continues, but should the trend move sideways for a while,
you'll profit on the calendar spreads. This will help to amortize the losses
in time value of the calls and straddles.
As you can see, it pays to build your knowledge base of options strategies.
Sometimes market conditions require strategies that need a little dusting,
since they aren't used as often. For example, put ratio backspreads were
useful when the market was selling off in 2000 and tech stocks were plummeting
50 points a week. Like clubs in your golf bag, you may not use these strategies
all the time, but it pays to know about them for those times when your
favorite strategies aren't profiting.
OPTIONS EXPIRATION
I've been told that 90% of options expire worthless. Is this true?
If so, why would anybody want to take the risk of trading options?
First of all, the belief that 90% of options expire worthless is untrue
and misleading. According to the CBOE, about 30% of options actually expire
worthless, 10% are exercised, and the other 60% are simply traded in the
marketplace - meaning that buyers sell their positions and writers buy
back their positions to close.
Before making any judgment on the danger of options, keep in mind their
inherent purpose. Options in and of themselves are hedging instruments,
meaning that their intended purpose is to protect assets from adverse price
movements. Institutional and retail investors alike purchase puts and calls
to reduce the risks associated with holding an underlying asset. They do
this to help protect their investments. However, much has changed since
options' inception and in many cases, the options on a particular stock
or index are as liquid as the stocks themselves. This is why many traders
find options desirable as trading vehicles.
Options are called derivatives because they derive their value
from the underlying asset. They are often traded with reckless abandon
by inexperienced traders who do not fully understand the consequences associated
with options' leveraged nature. These uninformed or inexperienced traders
do in fact lose their shirts quite often in the options market, but many
of their losses might be prevented with the proper education. All forms
of trading require proper money management and learned trade management
techniques. For example, if a trader is always buying 200-share lots in
equities, he should also consider trading two option contracts. This way,
he has truly reduced his risk exposure on the same equity by as much as
95% in many cases, while fully participating in the anticipated gains.
However, what normally occurs with inexperienced traders is they conclude
that they have 10 to 20 times more capital to spend as a result of this
leverage, and thus, will often recklessly purchase as many options as their
account size allows instead of instituting proper money management techniques.
Not only that, but they sometimes buy short-term options that expire in
less than 30 days - when there is the highest rate of time decay. This
decay accelerates the closer you get to expiration, and it will inhibit
your option's ability to appreciate in value, even if the underlying is
moving in the direction you anticipated.
As I've said before in this column, in the end, it's not options that
are dangerous; it's the people who trade them. Get the right education
first, exercise proper money management, become a success, and then judge
for yourself.
