the determined possibility factors are certainly enough to materially demonstrate the expected value alter in the situation and, if (two) the designs accustomed to compute sensitivities to those chance variables are accurate.
Ie: If We all know the inventory will almost certainly shut close to the opening price because it usually performs on a 1 vol, and its noon as well as the stock is down -10%, we realize that it should go higher in the previous few several hours of your working day and we could just outright invest in inventory to earn a living.
So How can delta-hedging frequency just impact the smoothness and variance of PnL if we can easily Plainly see it influences PnL itself in this instance?
– equanimity Commented Oct seven, 2021 at 1:07 $begingroup$ The get issues only for the cumulatuve brute-drive P&L. The buy isn't going to subject for impartial brute-force P&L or for chance-theoretical P&L (Taylor sereis approximation on the P&L utilizing deltas - first buy and gammas and cross-gammas - 2nd order possibility actions). I think you might be asking about RTPL? $endgroup$
Para ello tenemos que pensar en algo que realmente haga cambiar nuestra conducta habitual ante una situación, algo que sea aparentemente imposible.
In this instance, when we evaluate vol in more compact thirty min increments, we can easily see it is appreciably diverse than vol measured on close to close costs.

The one who hedges quite a few periods every day or the person who hedges as soon as at the end of the working day? In this instance, the stock is not really doing at some continuous vol at all times in time above the period on the life of the choice and all through each day, as a substitute we are able to begin to see the intraday vol is drastically various which the everyday close to shut vol.

I'm notably enthusiastic about how the "cross-consequences"* involving delta and gamma are taken care of and would love to see a straightforward numerical instance if which is feasible. Many thanks ahead of time!

Consider the delta neutral portfolio $Pi=C-frac partial C partial S S$. Assuming that the fascination amount and volatility aren't adjust in the little period of time $Delta t$. The P$&$L of your portfolio is given by
