$ Within the "perform scenario" you liquidate the portfolio at $t_1$ realising its PnL (allow me to simplify the notation a tad)
La PNL es un modelo que busca entender cómo las personas estructuran sus experiencias subjetivas y cómo pueden modificar sus patrones de pensamiento y comportamiento para alcanzar sus objetivos.

Depreciation = value firstly of the 12 months (opening equilibrium) + buys in the yr − benefit at the conclusion of the year (closing stability)
So, is it correct to convey then delta-hedging rebalancing frequency directly influences the quantity of P&L then? $endgroup$
Actual P&L calculated by Finance/ Item Handle and is based on the particular cost of the instrument on the market (or maybe the corresponding product if a sector does not exist). This reflects the true P&L When the position is shut at market costs.
And this depends on the rebalancing frequency. But "envisioned P&L" refers to a mean around all probable rate paths. So You can find not essentially a contradiction below. $endgroup$
$begingroup$ The data I have found about delta hedging frequency and (gamma) PnL on This website and various Other folks all reiterate the identical factor: which the frequency at which you delta-hedge only has an impact on the smoothness and variance of one's PnL.

Due to your final equality I know that the "faculty circumstance" pnl can take under consideration the performance with the dollars financial investment of your profit made together just how, that click here may be $PnL_1rdelta t$.
– equanimity Commented Oct seven, 2021 at one:07 $begingroup$ The get issues only for the cumulatuve brute-power P&L. The purchase does not make a difference for independent brute-drive P&L or for risk-theoretical P&L (Taylor sereis approximation of the P&L using deltas - first order and gammas and cross-gammas - next get possibility actions). I believe you're inquiring about RTPL? $endgroup$
$begingroup$ Very By natural means the two PnLs never automatically coincide. Inside the "college circumstance" You do not touch the portfolio at $t_1=t+delta t$ and liquidate it only at $t_2=t+twodelta t,.
Alternatively, the gamma PnL is paid for you over the side, not on the choice quality, but from your investing actions from the underlying you carry out your hedging account.
About any more time period, There is certainly not often a statistically sizeable autocorrelation in substantial frequency returns. If there was, then the above mentioned could be applicable which would dampen the outcome.
