264 • The Intelligent Option Investor
|
||||
Market risk is a factor that investors in levered instruments must
|
||||
always keep in mind. Even an ITM call long-term equity anticipated
|
||||
security (LEAPS) in the summer of 2007 might have become a short-tenor
|
||||
out-of-the-money (OTM) call by the fall of 2008 after the Lehman shock
|
||||
because of the sharp decline in stock prices in the interim. Unexpected
|
||||
things can and do happen. A portfolio constructed oblivious to this fact is
|
||||
a dangerous thing.
|
||||
As long as market fluctuations only cause unrealized losses, market
|
||||
risk is manageable. But if a levered loss must be realized, either because of
|
||||
an option expiration or in order to fund another position, it has the poten-
|
||||
tial to materially reduce your available investment capital. Y ou cannot ma-
|
||||
terially reduce your investment capital too many times before running out.
|
||||
A Lehman shock is a worst-case scenario, and some investors live
|
||||
their entire lives without experiencing such severe and material market
|
||||
risk. In most cases, rather than representing a material threat, market risk
|
||||
represents a wonderful opportunity to an intelligent investor.
|
||||
Most human decision makers in the market are looking at either
|
||||
technical indicators—which are short term by nature—or some sort of
|
||||
multiple value (e.g., price-to-something ratio). These kinds of measures are
|
||||
wonderful for brokers because they encourage brokerage clients to make
|
||||
frequent trades and thus pay the brokerages frequent fees.
|
||||
The reaction of short-term traders is also wonderful for intelligent
|
||||
investors. This is so because a market reaction that might look sensible or
|
||||
rational to someone with an investment time horizon measured in days or
|
||||
months will often look completely ridiculous to an investor with a longer-
|
||||
term perspective. For example, let’s say that a company announces that its
|
||||
earnings will be lower next quarter because of a delay in the release of a
|
||||
new product. Investors who are estimating a short-term value for the stock
|
||||
based on an earnings multiple will sell the stock when they see that earn-
|
||||
ings will likely fall. Technical traders see that the stock has broken through
|
||||
some line of “resistance” or that one moving average has crossed another
|
||||
moving average, so they sell it as well. Perhaps an algorithmic trading
|
||||
engine recognizes the sharp drop and places a series of sell orders that are
|
||||
covered almost as soon as they are filled. In the meantime, someone who
|
||||
has held the stock for a while and has a gain on it gets protective of this gain
|
||||
and decides to buy a put option to protect his or her gains.
