He intentado buscar las “evidencias” que respaldan estas presuposiciones, pero solo he encontrado una explicación a cada una de ellas.
How can model assumptions effects the interpretation of ends in device Discovering? additional scorching questions
Vega and Theta are sensetivities to volatility and time, respectively, so their contribution might be:
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.
Sin embargo, muchos defensores de la PNL argumentan que su valor radica en su enfoque práctico y en su capacidad para generar cambios rápidos y efectivos en las personas.
There are some subtleties to this type of attribution, particularly due to the fact that $sigma$ is often modeled website as a functionality of $S$ and $t$, so there are actually cross-consequences concerning the greeks which make it inexact.
You can also analyse the skewness and kurtosis on the period PnL by using third and 4th moments of $Y_t$ respectively. Presumably you are going to conclude that for 2 series with similar expectation and variance, you can favor the a person with constructive skew or lessen kurtosis, but perhaps not depending upon the self-confidence of the marketplace perspective, and so on..
$begingroup$ @nbbo2 I'm using the particular price path in the instance for a explanation, it disproves The premise of delta-hedging frequency in a roundabout way affecting PnL. And I imply "anticipated P&L" as the choice premium (PnL) replicated by delta-hedging a situation which can be calculated by subtracting understood volatility from implied volatility.
The above mentioned variation I rather see as follows: after we re-commit/re-borrow at $t_1$ to generate equally procedures concur we make the "operate situation" self-financing. In contrast, your company opts to Enable intermediate gains/losses fall out. There may very well be good reasons for this. Probably it's a method to work out taxes? I do not know. $endgroup$
Given that's an important amount (that will get reported, etc.) but that does not offer you a ton of knowledge on what generated that pnl. The second step is to maneuver just about every variable which could have an affect on your pnl to evaluate the contribution that a adjust In this particular variable has on the full pnl.
$begingroup$ Very Normally The 2 PnLs don't automatically coincide. Within 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,.
