You can also analyse the skewness and kurtosis in the period PnL by taking third and 4th times of $Y_t$ respectively. Presumably you are going to conclude that for 2 series with equivalent expectation and variance, you may like the a single with good skew or decrease kurtosis, but it's possible not depending upon the self-assurance of the market check out, and many others..
A través de la PNL descubrimos la estructura que sostiene la conducta propia y la del otro. Por lo tanto, investiga cómo nos comunicamos con nosotros mismos y con la gente de nuestro alrededor.
Composing for openDemocracy, Adem Ferizaj mentioned: "Within the one particular hand, PNL stands out sound-aesthetically from other rap artists by their choice of atmospheric and infrequently sentimental instrumentals.
$begingroup$ Not sure this is the valid dilemma! Gamma p/l is by definition the p/l resulting from realized volatility staying distinct from implied.
The online influence of all of that is that elevated delta hedging frequency does just provide the smoothing effect on P/L in excess of very long sufficient time horizons. But like you point out you're subjected to one particular-off or unusual necessarily mean reversion (or development) outcomes, but these dissipate above huge samples.

Be aware: I realize if you hedge discretely instead of continuously there'll be described as a hedging mistake, but make sure you ignore this mistake for the goal of this question.

Two traders have acquired a 100 strike ATM straddle (lengthy gamma) that expires in every week on stock XYZ. The inventory value is 100. They are both initially delta neutral. In the course of expiry, Trader A delta-hedges each and every minute, and trader B hedges every conclusion of day at sector close.
$begingroup$ Underneath the assumptions of GBM - namely that periodic returns are independent of one another - then hedging frequency may have 0 effect on the predicted website P/L after some time.
Alternatively, the gamma PnL is paid for you within the side, not on the choice top quality, but from the buying and selling routines within the fundamental you carry out your hedging account.
