$ While in the "work case" you liquidate the portfolio at $t_1$ realising its PnL (let me simplify the notation a tiny bit)
Depreciation = value at the beginning of the yr (opening equilibrium) + buys inside the calendar year − worth at the conclusion of the yr (closing balance)
At the end of the day, the EV/Avg(PNL) boils right down to iv vs rv of inventory. If Those people two are equivalent, then the EV/PNL will be the similar for both equally traders in spite of hedging frequency. The only real change will be the variance of their PNL as explained above.
The underside Line A P&L statement summarizes the revenues, expenses, and bills of a company through a specific interval. It is one of 3 monetary statements that community businesses situation quarterly and every year—one other two certainly are a balance sheet as well as a money circulation assertion.
It is important to compare the income assertion Together with the income movement statement because, underneath the accrual technique of accounting, a firm can log revenues and expenditures ahead of income modifications hands.
I'm keen on realizing the PnL between $t_0$ and $t_2$ of currently being lengthy one device of risky asset. Having said that I've two contradictory reasonings:
$begingroup$ Beneath the assumptions of GBM - namely that periodic returns are impartial of each other - then hedging frequency could have 0 impact on the expected P/L with time.
The implied volatility area and the choice Greeks - to what extent is the data contained inside their each day actions the identical? four
There are several subtleties to this sort of attribution, exclusively resulting from The point that $sigma$ is commonly modeled to be a function of $S$ and $t$, so there are cross-effects among the greeks that make it inexact.
So, could it be accurate to state then delta-hedging rebalancing frequency right impacts the amount of P&L then? $endgroup$
Roderique-Davies (2009) afirma que usar la palabra "neuro" en PNL es "efectivamente fraudulento dado que la PNL no ofrece ninguna explicación a nivel neuronal y se podría argumentar que su uso se alimenta falazmente en la noción de credibilidad científica".

Vega and Theta are sensetivities to volatility and time, respectively, so their contribution might be:
