By the end of this chapter, you should understand how changes in the follow-
|
||||
ing Black-Scholes-Merton model (BSM) drivers affect the price of an option:
|
||||
1. Moneyness
|
||||
2. Forward volatility
|
||||
3. Time to expiration
|
||||
4. Interest rates and dividend yields
|
||||
Y ou will also learn about the three measures of volatility—forward, im-
|
||||
plied, and statistical. Y ou will also understand what drivers affect option
|
||||
prices the most and how simultaneous changes to more than one variable
|
||||
may work for or against an option investment position.
|
||||
In this chapter and throughout this book in general, we will not try to
|
||||
figure out a precise value for any options but just learn to realize when an op-
|
||||
tion is clearly too expensive or too cheap vis-à-vis our rational expectations
|
||||
for a fair value of the underlying stock. As such, we will discuss pricing in
|
||||
general terms; for example, “This option will be much more expensive than
|
||||
that one. ” This generality frees us from the computational difficulties that
|
||||
come about when one tries to calculate too precise a price for a given op-
|
||||
tion. The BSM is designed to give a precise answer, but for investing, simply
|
||||
knowing that the price of some security is significantly different from what
|
||||
it should be is enough to give one an investing edge.
