And this relies on the rebalancing frequency. But "anticipated P&L" refers to an average around all achievable value paths. So There's not automatically a contradiction in this article. $endgroup$

Owing to your past equality I realize that the "college case" pnl usually takes under consideration the general performance of your money financial investment of your financial gain manufactured along how, that is definitely $PnL_1rdelta t$.
People two PnLs do not coincide. Which a single do you suspect helps make additional sense? Which is there a way to attach The 2?

The order isn't going to make any difference for independent brute-power P&L or for hazard-theoretical P&L (Taylor sereis approximation from the P&L applying deltas - initial buy and gammas and cross-gammas - next get chance steps). I feel you might be asking about RTPL? $endgroup$

$begingroup$ Not sure this can be a legitimate question! Gamma p/l is by definition the p/l as a result of recognized volatility staying unique from implied.
Para que nuestra mente inconsciente pueda “dibujar” un nuevo mapa tiene que actuar con un objetivo claro que responda a la pregunta ¿qué queremos? Y lo complicado es precisamente eso, que en muchas ocasiones no sabemos lo que queremos. Por lo tanto, no sabemos definir nuestro objetivo.
En una adicción o un mal comportamiento siempre hay una intención positiva, por tanto encontrando la raíz de ese problema y exteriorizando la intención positiva, se puede pasar de fumar durante 15 años a no tener esa necesidad.
So the thought here is usually that a trader who delta-hedges each individual moment, plus a trader who hedges each and every finish of day at pnl sector near, will the two possess the same envisioned financial gain at selection expiry and only their PnL smoothness/variance will differ. Let's put this to the take a look at.

There might be no scientific method to derive a "right" method.
The sensitivities technique [two] includes 1st calculating option sensitivities often called the Greeks due to prevalent follow of symbolizing the sensitivities using Greek letters.
The above mentioned big difference I rather see as follows: whenever we re-commit/re-borrow at $t_1$ to generate equally approaches agree we make the "perform situation" self-financing. In contrast, your business opts to Enable intermediate gains/losses fall out. There may be causes for this. Maybe it's a method to work out taxes? I don't know. $endgroup$
The second time period is due to your improve in desire price. $varepsilon$ is actually what You can not demonstrate. If every thing is neat, your $varepsilon$ should not be far too large. You may also see this is incredibly close to a Taylor enlargement when almost everything is linear, which is why You may use your length as an approximation with the 2nd phrase.
