For making The 2 methods equivalent you ought to visualize investing/borrowing $PnL_1$ at price $r$ to make sure that it stays during the procedure till $t_2,.$ At that time your
$begingroup$ For a possibility with price $C$, the P$&$L, with respect to modifications in the fundamental asset selling price $S$ and volatility $sigma$, is given by
$begingroup$ That you are proper that the full P&L (or as you get in touch with it The web P&L) needs to be the identical for The 2 solutions, so one thing went Completely wrong.
Los creadores de la PNL tomaron a tres maestros, Fritz Perls, Virginia Satir y Milton Ericksson y a través de diversos estudios cotejaron que estas tres personas poseían habilidades comunicativas especiales que les permitían obtener muy buenos resultados con sus pacientes.
In cases like this, when we measure vol in lesser 30 min increments, we could see it's appreciably distinctive than vol measured on shut to close charges. Each traders buy the straddle over a one vol for example, who do you think that could well be far better off? The one who hedges various times per day or the one who hedges at the time at the end of the day?

At the conclusion of the working day, the EV/Avg(PNL) boils down to iv vs rv of inventory. If These two are equivalent, then the EV/PNL will be the exact for both equally traders regardless of hedging frequency. The one difference will be the variance in their PNL as described previously mentioned.
$begingroup$ @nbbo2 I am employing the specific selling price path in the instance for the purpose, it disproves The idea of delta-hedging frequency not directly impacting PnL. And I indicate "expected P&L" as the option premium (PnL) replicated by delta-hedging a placement that may be calculated by subtracting recognized volatility from implied volatility.
The above mentioned variation I fairly see as follows: once we re-invest/re-borrow at $t_1$ to make each approaches concur we make the "operate situation" self-financing. In contrast, your business opts to Enable intermediate gains/losses fall out. There can be motives for this. Probably it truly is a technique to compute taxes? I don't know. $endgroup$
Now that's an important quantity (that gets reported, etc.) but that doesn't offer you a large amount of data on what created that pnl. The next phase is to move every single variable that can influence your pnl to evaluate the contribution that a alter Within this variable has on the total pnl.
$begingroup$ Pretty By natural means the two PnLs usually do not essentially coincide. While in the "faculty situation" You do not touch the portfolio at $t_1=t+delta t$ and liquidate it only at $t_2=t+2delta t,.
