$ While in the "perform scenario" you liquidate the portfolio at $t_1$ realising its PnL (allow me to simplify the notation a tad)

Traders and analysts use money statements to evaluate the financial well being of an organization and its progress likely.
There are many subtleties to such a attribution, exclusively resulting from The point that $sigma$ is commonly modeled to be a function of $S$ and $t$, so you will find cross-results among the greeks that make it inexact.
Take into account the delta neutral portfolio $Pi=C-frac partial C partial S S$. Assuming that the desire fee and volatility usually are not alter in the modest time period $Delta t$. The P$&$L of your portfolio is presented by
Roderique-Davies (2009) afirma que usar la palabra "neuro" en PNL es "efectivamente fraudulento dado que la PNL no ofrece ninguna explicación a nivel neuronal y se podría argumentar que su uso se alimenta falazmente en la noción de credibilidad científica".
