You may also analyse the skewness and kurtosis from the interval PnL by using third and 4th times of $Y_t$ respectively. Presumably you might conclude that for two collection with equivalent expectation and variance, you may choose the just one with constructive skew or lower kurtosis, but perhaps not depending on the self confidence of the industry view, and so forth..
Aunque puede no ser una panacea, la PNL puede ser una herramienta útil cuando se utiliza de manera adecuada y en combinación con otras formas de terapia o coaching.
Plus the incremental PnL of a long tactic amongst $t$ and $t+delta t$ is calculated because the gain created by borrowing The cash to purchase the dangerous property at $t$, then selling out your posture at $t+delta t$. So in my instance:
Evaluate the delta neutral portfolio $Pi=C-frac partial C partial S S$. Assuming which the desire price and volatility will not be improve during the little period of time $Delta t$. The P$&$L with the portfolio is supplied by
The online outcome of all that is always that amplified delta hedging frequency does just have the smoothing effect on P/L in excess of long adequate time horizons. But such as you point out you are exposed to 1-off or exceptional necessarily mean reversion (or development) effects, but these dissipate over big samples.

On the other hand, the existence of major autocorrelation from the return system would hint that we can trade applying futures/linear items over a intraday horizon which might likely (immediately after accounting for liquidity and theta) establish additional profitable to trade than the delta hedging system.

The get isn't going to matter for unbiased brute-pressure P&L or for chance-theoretical P&L (Taylor sereis approximation in the P&L making use of deltas - initial get and gammas and cross-gammas - 2nd purchase risk steps). I believe you happen to be asking about RTPL? $endgroup$

$begingroup$ In Black Scholes framework, assuming zero curiosity premiums and understood volatility being similar as implied volatility, gamma pnl is strictly similar and reverse of theta pnl.
