Day Two
|
||||
The next day, the market is a bit quieter. There is a $0.40 drop in the price
|
||||
of the stock, at which point the position delta is short 1.12. Harry buys 112
|
||||
shares at $39.60 to get delta neutral.
|
||||
Following Harry’s purchase, the stock slowly drifts back up and is trading
|
||||
at $40 near the close. Harry decides to cover his deltas and sell 112 shares
|
||||
at $40. It is common to cover all deltas at the end of the day to get back to
|
||||
being delta neutral. Remember, the goal of gamma scalping is to trade
|
||||
volatility, not direction. Starting the next trading day with a delta, either
|
||||
positive or negative, means an often unwanted directional bias and
|
||||
unwanted directional risk. Tidying up deltas at the end of the day to get
|
||||
neutral is called going home flat.
|
||||
Today was not a banner day. Harry did not quite have the opportunity to
|
||||
cover the decay.
