You can even analyse the skewness and kurtosis on the interval PnL by getting third and 4th times of $Y_t$ respectively. Presumably you are going to conclude that for 2 series with identical expectation and variance, you can favor the a single with positive skew or decreased kurtosis, but it's possible not dependant upon the assurance of the market check out, etcetera..
$begingroup$ In case you take a look at just a single example, it may well seem like the frequency of hedging specifically effects the EV/Avg(Pnl), like in the problem you described the place hedging each and every moment proved being more rewarding.
Now, in the above rationalization, we assumed the stock was performing on some frequent vol in the slightest degree times in time. Imagine if the intraday vol diverges drastically from the each day vol? Ie: Being an EXAGGERATION, say you look at some inventory and you also work out from your past ten day closing charges that the stock is performing on the one vol. Virtually closes wherever it opened every day. You then commit to seem closer and evaluate vol in thirty minute increments as an alternative to by day by day closing costs. If you look intraday/thirty min increments, the thing is the stock moves quite a bit, but based on closing selling prices performs nonetheless over a 1 vol.
Take into account the delta neutral portfolio $Pi=C-frac partial C partial S S$. Assuming the desire level and volatility aren't alter in the course of the compact time period $Delta t$. The P$&$L of the portfolio is given by
Bandler y Grinder, han observado que los movimientos involuntarios de los ojos en una u otra dirección, no son al azar sino que están relacionados con la manera de pensar de la persona:
La PNL parte de la premisa de que las personas tienen dentro de sí mismas los recursos necesarios para realizar cambios positivos. El trabajo del terapeuta o coach es ayudar a la persona a acceder a estos recursos y utilizarlos de manera efectiva.
So So how exactly does delta-hedging frequency just have an affect on the smoothness and variance of PnL if we can Evidently see it affects PnL itself in this example?
Vega p/l is by definition the p/l due to moves in implied volatility. The 2nd Portion of the question you may have answered your self. Shorter dated possibilities have more gamma publicity, very long dated choices have extra vega publicity.
The 2nd term is due to your improve in curiosity level. $varepsilon$ is just what You can not describe. If every thing is neat, your $varepsilon$ really should not be as well superior.

The buy would not make any difference for independent brute-power P&L or for risk-theoretical P&L (Taylor sereis approximation of your P&L employing deltas - to start with purchase and gammas and cross-gammas - second get chance measures). I feel you happen to be inquiring about RTPL? $endgroup$
$begingroup$ Pretty naturally the two PnLs usually do not essentially coincide. Within the "college situation" you don't touch the portfolio at $t_1=t+delta t$ and liquidate it only at $t_2=t+twodelta t,.
Notice this is dependent upon the community regulation, hence the same place can likely have various Cleanse P&L if booked in books which have been matter to unique regulators. Cleanse P&L is employed for backtesting VaR types for regulatory cash.
