an extended period of time can produce a loser even if IV rises. Gamma is
|
||||
potentially connected to the success of this trade, too. If the underlying
|
||||
moves in either direction, profit from deltas created by positive gamma may
|
||||
offset the losses from theta. In fact, a big enough move in either direction
|
||||
can produce a profitable trade, regardless of what happens to IV.
|
||||
Imagine, for a moment, that this trade is held until expiration. If the stock
|
||||
is below the strike price at this point, the calls expire. The resulting position
|
||||
is short 1,000 shares of stock. If the stock is above the strike price at
|
||||
expiration, the calls can be exercised, creating 2,000 shares of long stock.
|
||||
Because the trade is already short 1,000 shares, the resulting net position is
|
||||
long 1,000 shares (2,000 − 1,000). Clearly, the more the underlying stock
|
||||
moves in either direction the greater the profit potential. The underlying has
|
||||
to move far enough above or below the strike price to allow the beneficial
|
||||
gains from buying or selling stock to cover the option premium lost from
|
||||
time decay. If the trade is held until expiration, the underlying needs to
|
||||
move far enough to cover the entire premium spent on the calls.
|
||||
The solid lines forming a V in Exhibit 12.2 conceptually illustrate the
|
||||
profit or loss for this delta-neutral long call at expiration.

Because of gamma, some deltas will be created by movement of the
|

underlying before expiration. Gamma may lead to this being a profitable
