Legging Out
|
||||
There are many ways to exiting a straddle. In the right circumstances,
|
||||
legging out is the preferred method. Instead of buying and selling stock to
|
||||
lock in profits and maintain delta neutrality, traders can reduce their
|
||||
positions by selling off some of the calls or puts that are part of the straddle.
|
||||
In this technique, when the underlying rises, traders sell as many calls as
|
||||
needed to reduce the delta to zero. As the underlying falls, they sell enough
|
||||
puts to reduce their position to zero delta. As the stock oscillates, they
|
||||
whittle away at the position with each hedging transaction. This serves the
|
||||
dual purpose of taking profits and reducing risk.

||||
A trader, Susan, has been studying Acme Brokerage Co. (ABC). Susan
|
||||
has noticed that brokerage stocks have been fairly volatile in recent past.
|
||||
Exhibit 15.3 shows an analysis of Acme’s volatility over the past 30 days.

|
||||
During this period, Acme stock ranged more than $11 in price. In this
|
||||
example, Acme’s volatility is a function of interest rate concerns and other
|
||||
macroeconomic issues affecting the brokerage industry as a whole. As the
|
||||
stock price begins to level off in the latter half of the 30-day period, realized
|
||||
volatility begins to ebb. The front month’s IV recedes toward recent lows as
|
||||
well. At this point, both realized and implied volatility converge at 36
|
||||
percent. Although volatility is at its low for the past month, it is still
|
||||
relatively high for a brokerage stock under normal market conditions.
|
||||
Susan does not believe that the volatility plaguing this stock is over. She
|
||||
believes that an upcoming scheduled Federal Reserve Board announcement
|
||||
will lead to more volatility. She perceives this to be a volatility-buying
|
||||
opportunity. Effectively, she wants to buy volatility on the dip. Susan pays
|
||||
5.75 for 20 July 75-strike straddles.

|
||||
expiration.
