$begingroup$ Should you properly hedge (infinitesimal moves), theta will offset gamma but when you need to do periodic hedges for finite moves, you would have gamma slippage after which you end up within a distribution of Pnl close to zero.
Nivel Egres: From your viewpoint of gamma pnl, The one thing that matters is definitely the change inside your asset price tag. Frequency is irrelevant - you could rebalance at unique time durations or when delta exceeds a threshold or a number of other items - it is still an approximation of continuous integral plus your envisioned P&L can be the exact same.
How Is that this real although? Delta-hedging frequency provides a immediate effect on your PnL, and not simply the smoothness of it.
Aunque la PNL no está exenta de críticas, su enfoque centrado en la experiencia subjetiva y su énfasis en la flexibilidad y la adaptabilidad la convierten en una herramienta valiosa para aquellos que buscan mejorar su calidad de vida y alcanzar sus objetivos.
La PNL es un modelo que busca entender cómo las more info personas estructuran sus experiencias subjetivas y cómo pueden modificar sus patrones de pensamiento y comportamiento para alcanzar sus objetivos.

You can even analyse the skewness and kurtosis of your time period PnL by getting third and 4th moments of $Y_t$ respectively. Presumably you may conclude that for 2 series with similar expectation and variance, you might favor the one particular with positive skew or decrease kurtosis, but it's possible not with regards to the self esteem of the market check out, and so on..
Una vez fijado nuestro objetivo, debemos revisar nuestras creencias y valores. Aquello que tenemos profundamente arraigado en nosotros mismos y que nos impide alcanzar nuestros sueños.

Debemos cambiar nuestras estructuras de creencias negativas que nos ponen impedimentos para ir hacia nuestro objetivo.
$begingroup$ The data I have found about delta hedging frequency and (gamma) PnL on This website and numerous Some others all reiterate a similar thing: which the frequency at which you delta-hedge only has an effect on the smoothness and variance of the PnL.
