And this depends on the rebalancing frequency. But "anticipated P&L" refers to a median in excess of all doable rate paths. So there is not essentially a contradiction here. $endgroup$
Say that you choose to buy an from the money solution after which you can the marketplace just dies. You then get noting but theta losses. They'll add up to your premium you paid out and dropped.
$begingroup$ When you correctly hedge (infinitesimal moves), theta will offset gamma but if you need to do periodic hedges for finite moves, you might have gamma slippage then you end up in the distribution of Pnl all around zero.
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.

There are many subtleties to this kind of attribution, specifically as a consequence of The reality that $sigma$ is usually modeled like a perform of $S$ and $t$, so you will find cross-effects among the greeks which make it inexact.
You may as well analyse the skewness and kurtosis in the interval PnL by using third and 4th times of $Y_t$ respectively. Presumably you'll conclude that for 2 collection with identical expectation and variance, you are going to want the 1 with constructive skew or lessen kurtosis, but perhaps not depending upon the self-assurance of the marketplace view, and so forth..
$begingroup$ @nbbo2 I am website employing the specific selling price path in the example for any reason, it disproves The idea of delta-hedging frequency not directly impacting PnL. And that i suggest "anticipated P&L" as the choice premium (PnL) replicated by delta-hedging a placement which can be calculated by subtracting recognized volatility from implied volatility.
Las técnicas de PNL pueden ayudar a las personas a cambiar patrones de pensamiento negativos y desarrollar estrategias más efectivas para manejar sus emociones.
As stated I never Feel just one approach is more specific, but a technique could be needed or recommended by business standards or polices.
$begingroup$ I have a time series of $pnl of a technique and nothing at all else. Am i able to use it to come up with some type of a efficiency measure altered for danger? Is $$ frac normal($pnl) sigma($pnl) $$ ok to utilize in this article? Are there ways of strengthening it? Can it be exact same as sharpe ratio?
