And this depends on the rebalancing frequency. But "expected P&L" refers to a median in excess of all doable price paths. So There's not necessarily a contradiction right here. $endgroup$
Say which you buy an outside of The cash choice and after that the industry just dies. You then get noting but theta losses. They may incorporate up towards the quality you paid out and lost.
$begingroup$ In case you beautifully hedge (infinitesimal moves), theta will offset gamma however, if you need to do periodic hedges for finite moves, you would've gamma slippage after which you can you end up within a distribution of Pnl close to zero.
Nivel Egres: From the perspective of gamma pnl, The one thing that issues could be the modify with your asset value. Frequency is irrelevant - it is possible to rebalance at diverse time intervals or when delta exceeds a threshold or a number of other items - it continues to be an approximation of steady integral and also your predicted P&L can be a similar.
I wish to work out the netPnL, realizedPnl and unrealizedPnl by using the most precise valuation form. I only know 3 valuation types
Vega and Theta are sensetivities to volatility and time, respectively, so their contribution will be:
If there is autocorrelation while in the intraday return approach that you decide on to hedge at (that may consequently influence each day annualised volatility), then your P/L is undoubtedly influenced by your selection of hedging interval.
$begingroup$ It is actually in fact. It really is especially appealing more info within a portfolio where you is often hedging some hazards and maintaining Many others. $endgroup$
La mirada dirigida hacia el ángulos superior derecho revela que estamos construyendo imágenes de aquello que estamos diciendo.
Would be the calculations correct? I assumed the netPnl must be normally the exact same - regardless of the valuation sort

$begingroup$ The data I have discovered about delta hedging frequency and (gamma) PnL on this site and diverse Other individuals all reiterate exactly the same issue: the frequency at which you delta-hedge only has an impact on the smoothness and variance of your PnL.
