When comparing Exhibit 4.5 to Exhibit 4.3 , it’s easy to see that as the
|
||||
time value of the option declines, so does Kim’s exposure to vega. As time
|
||||
passes, vega gets smaller. And as the call becomes more in- or out-of-the-
|
||||
money, vega gets smaller. Since she plans to hold the position for around
|
||||
three weeks, she is not concerned about small fluctuations in IV in the
|
||||
interim.
|
||||
If indeed the rise in price that Kim anticipates comes to pass, vega
|
||||
becomes even less of a concern. With 23 days to expiration and DIS at $37,
|
||||
the call value is 2.21. The vega is $0.018. If IV decreases as the stock price
|
||||
rises—a common occurrence—the adverse effect of vega will be minimal.
|
||||
Even if IV declines by 5 points, to a historically low IV for DIS, the call
|
||||
loses less than $0.10. That’s less than 5 percent of the new value of the
|
||||
option.
|
||||
If dividend policy changes or the interest rate changes, the value of Kim’s
|
||||
call will be affected as well. Dividends are often fairly predictable.
|
||||
However, a large unexpected dividend payment can have a significant
|
||||
adverse impact on the value of the call. For example, if a surprise $3
|
||||
dividend were announced, owning the stock would become greatly
|
||||
preferable to owning the call. This preference would be reflected in the call
|
||||
premium. This is a scenario that an experienced trader like Kim will realize
|
||||
is a possibility, although not a probability. Although she knows it can
