I discovered a serious oversight inside of a paper published by my professor's preceding pupil. To whom must I report my findings?

$begingroup$ When you have a time number of accumulated/on heading PnL figures, $X_t$, you ought to be very careful to convert these right into a far more stationary info number of time period PnL changes (possibly daily improvements):
Nivel Egres: In the perspective of gamma pnl, the only thing that issues is the change in your asset rate. Frequency is irrelevant - you could rebalance at different time durations or when delta exceeds a threshold or all kinds of other points - it remains to be an approximation of constant integral as well as your expected P&L would be the same.

$begingroup$ The theta PnL here is the choice value paid out (for enough time-worth of the option); it is just a greek phrase for it with an extra element demonstrating how the option top quality continously declines Together with the passage of your time.
En una adicción o un mal comportamiento siempre hay una intención positiva, por tanto encontrando la raíz de ese problema y exteriorizando la intención positiva, se puede pasar de fumar durante 15 años a no tener esa necesidad.
Por ejemplo, una persona que fuma puede estar buscando aliviar el estrés o la ansiedad. La PNL busca identificar la intención positiva detrás del comportamiento y encontrar formas más saludables de satisfacer esa necesidad.
As it is the pnl from the hedge that offsets the option top quality. Remember to disregard variances resulting from periodic vs ongoing for this problem. $endgroup$
Esto en realidad puede llevar a graves dificultades a la hora de elaborar un mensaje, ya que centrarnos en las reacciones o estar en alerta ante posibles consecuencias, no es algo que vaya aportar calidad a la comunicación.
. y ahora escribo con la derecha pero uso la mano izquierda mejor a veces q la derecha,, cómo sería esto? por ejemplo me gusta el arte pero me doy cuenta q no logro realizarme en eso..puede tener que ver lo que me ha pasado de chica? Responder
The next term is because of your modify in interest amount. $varepsilon$ is just what You can not make clear. If every thing is neat, your $varepsilon$ really should not be way too higher. You may as well see that this may be very near to a Taylor enlargement when almost everything is linear, which is pnl why You should utilize your duration being an approximation for your 2nd time period.
$begingroup$ The data I have found about delta hedging frequency and (gamma) PnL on This website and diverse Other folks all reiterate a similar thing: that the frequency at which you delta-hedge only has an effect on the smoothness and variance of the PnL.
