Trader A has designed some hefty PnL, meanwhile Trader B will come out with absolutely nothing in any way and his skipped out on volatility over the trading day which he could've profited off of had he been continually hedging as opposed to just at the time each day.
$begingroup$ I have a time number of $pnl of a method and very little else. Am i able to use it to think of some sort of a efficiency measure modified for hazard? Is $$ frac average($pnl) sigma($pnl) $$ ok to utilize listed here? Are there means of increasing it? Is it same as sharpe ratio?
Nivel Egres: Through the point of view of gamma pnl, the only thing that issues would be the modify in your asset cost. Frequency is irrelevant - you may rebalance at diverse time intervals or when delta exceeds a threshold or many other issues - it is still an approximation of constant integral plus your predicted P&L could be exactly the same.
$begingroup$ The theta PnL Here's the option value paid (for the time-value of the option); it is simply a greek term for it with an additional element exhibiting how the option premium continously declines with the passage of time.
Say that you just buy an from The cash choice then the marketplace just dies. You then get noting but theta losses. They're going to incorporate up for the premium you compensated and missing.
So How can delta-hedging frequency just affect the smoothness website and variance of PnL if we will Evidently see it affects PnL itself in this instance?
Which is dependent upon the rebalancing frequency. But "anticipated P&L" refers to a mean over all probable value paths. So You can find not necessarily a contradiction here. $endgroup$
La PNL también se aplica en el campo de la educación para mejorar el aprendizaje y la enseñanza.

I am keen on understanding the PnL in between $t_0$ and $t_2$ of staying extensive one unit of risky asset. Nevertheless I have two contradictory reasonings:
The PnL among $t$ and $T$ is the sum of all incrementals PnLs. That is certainly if we denote by $PnL_ uto v $ the PnL concerning situations $u$ and $v$, then
I want to calculate the netPnL, realizedPnl and unrealizedPnl by utilizing the most specific valuation style. I only know three valuation varieties
About any more time period, There exists hardly a statistically significant autocorrelation in higher frequency returns. If there was, then the above will be applicable which would dampen the impact.
