$begingroup$ When you've got a time series of gathered/on going PnL figures, $X_t$, you have to be very careful to convert these right into a far more stationary data number of period PnL improvements (almost certainly everyday improvements):
so what you lose on high quality payment you acquire on the gamma buying and selling account so you crack whilst you count on!
As well as incremental PnL of an extended approach concerning $t$ and $t+delta t$ is calculated given that the financial gain made by borrowing The cash to buy the risky belongings at $t$, then marketing out your position at $t+delta t$. So in my illustration:
Indicating if $sigma$ variations since the fundamental alterations you may account for that next-buy influence with extra sensitivities (vanna specially), but Those people consequences are typically Significantly smaller sized and may be insignificant determined by your reason.
Two traders have bought a a hundred strike ATM straddle (lengthy gamma) that expires in per week on inventory XYZ. The inventory price is a hundred.

The net result of all of that is usually read more that improved delta hedging frequency does just provide the smoothing impact on P/L around very long more than enough time horizons. But such as you suggest that you are subjected to one-off or uncommon imply reversion (or pattern) results, but these dissipate more than huge samples.
In the 2015 report for i-D, Gino Delmas described PNL: "Prolonged hair for one, slicked again for the other, restricted polo shirt, a mix of Activity and designer clothing.
