You can also analyse the skewness and kurtosis of the interval PnL by taking 3rd and 4th moments of $Y_t$ respectively. Presumably you will conclude that for two sequence with similar expectation and variance, you can desire the a person with optimistic skew or lessen kurtosis, but possibly not according to the self-confidence of the marketplace see, etcetera..

Virtually closes where it opened daily. You then commit to appear nearer and measure vol in 30 moment increments rather then by everyday closing selling prices. Whenever you glimpse intraday/30 min increments, you see the inventory moves a lot, but determined by closing selling prices performs nevertheless with a 1 vol.

Nivel Egres: From the viewpoint of gamma pnl, the only thing that issues is definitely the change in your asset price tag.

WillWill 13344 bronze badges $endgroup$ four $begingroup$ Did you not say initially that $V$ is self-funding? In that situation there is not any Value to finance it and also the PnL is often just $V_T-V_t$ involving any two time points. $endgroup$

Two traders have purchased a 100 strike ATM straddle (lengthy gamma) that expires in each week on inventory XYZ. The inventory selling price is one hundred. They may be each initially delta neutral. Throughout expiry, Trader A delta-hedges every single minute, and trader B hedges every close of day at marketplace shut.

$begingroup$ Really In a natural way The 2 PnLs will not essentially coincide. In the "school case" you don't contact the portfolio at $t_1=t+delta t$ and liquidate it only at $t_2=t+twodelta t,.

It appeared as though for The 1st time a French team had managed to wholly translate the new codes from across the Atlantic into French.
