$begingroup$ The pnl calculation is completed in two methods. By definition, you benefit your portfolio as of today, you value your portfolio as of yesterday, and the main difference are going to be your pnl.

$begingroup$ The theta PnL Here's the choice rate compensated (for some time-value of the choice); it is simply a greek word for it with an extra function displaying how the option high quality continously declines Together with the passage of your time.
$begingroup$ In Black Scholes framework, assuming zero interest rates and understood volatility to get identical as implied volatility, gamma pnl read more is exactly exact same and reverse of theta pnl.
There are a few subtleties to such a attribution, specially due to The truth that $sigma$ is usually modeled as being a functionality of $S$ and $t$, so there are actually cross-consequences involving the greeks which make it inexact.
It's also possible to analyse the skewness and kurtosis of the time period PnL by getting third and 4th moments of $Y_t$ respectively. Presumably you may conclude that for 2 collection with identical expectation and variance, you may like the 1 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 utilizing the precise cost route in the example for any reason, it disproves The idea of delta-hedging frequency not directly impacting PnL. And that i suggest "envisioned P&L" as the option high quality (PnL) replicated by delta-hedging a position which may be calculated by subtracting understood volatility from implied volatility.
El modelado es una técnica que implica observar y replicar los patrones de pensamiento y comportamiento de personas que han logrado éxito en un área específica.
