And this depends on the rebalancing frequency. But "expected P&L" refers to a median in excess of all doable selling price paths. So there is not automatically a contradiction below. $endgroup$
Si intentas una manera de abordar un problema y no obtienes los resultados que esperabas, intenta algo diferente, y sigue variando tu comportamiento hasta que consigas la respuesta que estabas buscando.
La PNL se basa en varios principios fundamentales que guían su aplicación. Estos principios son esenciales para entender cómo funciona la PNL y cómo se puede utilizar para generar cambios positivos.
Nivel Egres: From the standpoint of gamma pnl, The one thing that issues is definitely the adjust with your asset price tag. Frequency is irrelevant - you may rebalance at unique time intervals or when delta exceeds a threshold or a number of other items - it continues to be an approximation of continuous integral as well as your expected P&L will be the identical.

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.

There are a few subtleties to this type of attribution, specifically because of the fact that $sigma$ is often modeled as a function of $S$ and $t$, so you will find cross-effects between the greeks which make it inexact.
– Will Commented Nov 24, 2024 at 22:fifteen $begingroup$ I am not an accountant but I believe that these concerns have far more to do with conventions and becoming steady in order to inform if, say, last calendar year's PnL was greater or even worse than this 12 months's. There might be no scientific approach to derive a "right" method.

The PnL among $t$ and $T$ is the sum of all incrementals PnLs. That may be if we denote by $PnL_ uto v $ the PnL amongst times $u$ and $v$, then
P&L could be the day-around-day improve in the value of the portfolio of trades normally calculated applying the following system: PnL = Value now − Worth from Prior Working day
$begingroup$ The information I have found about delta hedging frequency and (gamma) PnL on This web site and diverse Some others all reiterate the same point: the frequency at which you delta-hedge only has an effect on the smoothness and variance of your respective PnL.
