Therefore the thought in this article is the fact a trader who delta-hedges each and every minute, and a trader who hedges just about every stop of working day at current market shut, will both of those provide the identical expected gain at selection expiry and only their PnL smoothness/variance will differ. Let us put this into the examination.
This means if $sigma$ variations since the underlying adjustments you may account for that second-get outcome with more sensitivities (vanna specially), but All those outcomes are typically A lot smaller and may be insignificant dependant upon your intent.
Now that's a very important range (that gets reported, and many others.) but that does not give you a ton of information on what produced that pnl. The second phase is to maneuver every single variable that may have an affect on your pnl to measure the contribution that a improve On this variable has on the full pnl.

The buy will not issue for independent brute-force P&L or for chance-theoretical P&L (Taylor sereis approximation in the P&L using deltas - initial purchase and gammas and cross-gammas - next buy chance actions). I think you're inquiring about RTPL? $endgroup$
$begingroup$ Beneath the assumptions of GBM - particularly that periodic returns are unbiased of each other - then hedging frequency will have 0 impact on the anticipated P/L after some time.
