before the option expires. The reason for this is that although the intrinsic value
|
||||
represents the actual upside of the stock’s price over the option strike price,
|
||||
there is still the possibility that the stock price will move further upward in the
|
||||
future. This possibility for the stock to move further upward is the potential bit
|
||||
mentioned earlier. Formally, this is called the time value of an option.
|
||||
Let us say that our one-year call option struck at $40 on a $50 stock
|
||||
costs $11.20. Here is the breakdown of this example’s option price into in-
|
||||
trinsic and time value:
|
||||
$10.00 Intrinsic value: the amount by which the option is ITM
|
||||
+ $1.20 Time value: represents the future upside potential of the stock
|
||||
= $11.20 Overall option price
|
||||
Recall that earlier in this book I mentioned that it is almost always a mis-
|
||||
take to exercise a call option when it is ITM. The reason that it is almost always
|
||||
a mistake is the existence of time value. If we exercised the preceding option,
|
||||
we would generate a gain of exactly the amount of intrinsic value—$10. How-
|
||||
ever, if instead we sold the preceding option, we would generate a gain totaling
|
||||
both the intrinsic value and the time value—$11.20 in this example—and then
|
||||
we could use that gain to purchase the stock in the open market if we wanted.
|
||||
Our way of representing the purchase of an ITM call option from a
|
||||
risk-reward perspective is as follows:
