Vega and Theta are sensetivities to volatility and time, respectively, so their contribution would be:

Now, in the above mentioned clarification, we assumed the stock was accomplishing on some frequent vol in the least moments in time. Imagine if the intraday vol diverges appreciably in the day-to-day vol? Ie: Being an EXAGGERATION, say you look at some inventory and also you estimate through the past ten day closing rates which the stock is undertaking on the one vol. Basically closes where by it opened day after day. You then opt to appear closer and evaluate vol in thirty minute increments rather then by everyday closing costs. If you glimpse intraday/thirty min increments, the thing is the stock moves a great deal, but dependant on closing costs performs however on a 1 vol.

$begingroup$ Should you have a time number of accrued/on going PnL figures, $X_t$, you need to be very careful to transform these into a more stationary knowledge series of time period PnL adjustments (almost certainly day by day improvements):

Indicating if $sigma$ improvements since the underlying adjustments you can account for that next-buy influence with added sensitivities (vanna exclusively), but Individuals results are usually A lot smaller and might be insignificant according to your objective.

And this depends upon the rebalancing frequency. But "expected P&L" refers to a mean around all possible rate paths. So You can find not essentially a contradiction below. $endgroup$

The get won't issue for independent brute-force P&L or for risk-theoretical P&L (Taylor sereis approximation of your P&L applying deltas - initially purchase and gammas and cross-gammas - second get possibility actions). I do think you happen to be asking about RTPL? $endgroup$

The PnL involving $t$ and $T$ will be the sum of all incrementals PnLs. That is definitely if we denote by $PnL_ uto v $ the PnL concerning occasions $u$ and $v$, then
