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.
$begingroup$ For an option with cost $C$, the P$&$L, with respect to adjustments on the fundamental asset price $S$ and volatility $sigma$, is presented by
Aunque puede no ser una panacea, la PNL puede ser una herramienta útil cuando se utiliza de manera adecuada y en combinación con otras formas de terapia o coaching.
How is this legitimate however? Delta-hedging frequency features a immediate effect on your PnL, and not just the smoothness of it.
$begingroup$ Undecided this can be a legitimate issue! Gamma p/l is by definition the p/l as a consequence of realized volatility being unique from implied.
one $begingroup$ @KaiSqDist: that may be A different problem. The approximation here is related to the recognized volatility. $endgroup$

The PnL involving $t$ and $T$ would be the sum of all incrementals PnLs. That is if we denote by $PnL_ uto v $ the PnL concerning instances $u$ and $v$, then
Now that's an essential amount (that gets reported, etc.) but that does not provide you with a whole lot of knowledge on what produced that pnl. The second stage is to maneuver each and every variable that might have an click here effect on your pnl to measure the contribution that a alter Within this variable has on the total pnl.
$begingroup$ Pretty In a natural way the two PnLs tend not to necessarily coincide. In the "school situation" you don't touch the portfolio at $t_1=t+delta t$ and liquidate it only at $t_2=t+2delta t,.
