At seven days until expiration, there is less time for price action in the
|
||||
stock to change the expected moneyness at expiration of ITMs or OTMs.
|
||||
ATM options, however, continue to be in play. Here, the ATM gamma is
|
||||
approaching 0.35. But the strikes below 41 and above 48 have 0 gamma.
|
||||
Similarly-priced securities that tend to experience bigger price swings
|
||||
may have strikes $3 away-from-the-money with seven-day gammas greater
|
||||
than zero. The volatility of the underlying will affect gamma, too. Exhibit
|
||||
2.9 shows the same 19 percent volatility QQQ calls in contrast with a graph
|
||||
of the gamma if the volatility is doubled.
|
||||
EXHIBIT 2.9 Gamma as volatility changes.
|
||||
Raising the volatility assumption flattens the curve, causing ITM and
|
||||
OTM to have higher gamma while lowering the gamma for ATMs.
|
||||
Short-term ATM options with low volatility have the highest gamma.
|
||||
Lower gamma is found in ATMs when volatility is higher and it is lower for
|
||||
ITMs and OTMs and in longer-dated options.
