2. Realized Volatility Rises, Implied
|
||||
Volatility Remains Constant
|
||||
This chart pattern can develop from a few different market conditions. One
|
||||
scenario is a one-time unanticipated move in the underlying that is not
|
||||
expected to affect future volatility. Once the news is priced into the stock,
|
||||
there is no point in hedgers’ buying options for protection or speculators’
|
||||
buying options for a leveraged bet. What has happened has happened.
|
||||
There are other conditions that can cause this type of pattern to
|
||||
materialize. In Exhibit 14.3 , the IV was trading around 25 for several
|
||||
months, while the realized volatility was lagging. With hindsight, it makes
|
||||
perfect sense that something had to give—either IV needed to fall to meet
|
||||
realized, or realized would rise to meet market expectations. Here, indeed,
|
||||
the latter materialized as realized volatility had a steady rise to and through
|
||||
the 25 level in May. Implied, however remained constant.
|
||||
EXHIBIT 14.3 Realized volatility rises, implied volatility remains
|
||||
constant.

Traders who were long volatility going into the May realized-vol rise
|
||||
probably reaped some gamma benefits. But those who got in “too early,”
|
||||
buying in January or February, would have suffered too great of theta losses
|
||||
before gaining any significant profits from gamma. Time decay (theta) can
|
||||
inflict a slow, painful death on an option buyer. By studying this chart in
|
||||
hindsight, it is clear that options were priced too high for a gamma scalper
|
||||
to have a fighting chance of covering the daily theta before the rise in May.
