Which depends upon the rebalancing frequency. But "anticipated P&L" refers to a median about all probable price paths. So There is certainly not always a contradiction below. $endgroup$
Ie: If We all know the stock will almost certainly near near the opening rate as it often performs on the 1 vol, and its midday as well as the stock is down -ten%, we are aware that it should go larger in the last few several hours on the day and we could just outright buy inventory to earn a living.
The arrest was filmed by several followers and appeared to indicate him staying held on the bottom by law enforcement officers, and after that handcuffed.[22]
Nivel Egres: Within the point of view of gamma pnl, the only thing that matters may be the alter in the asset price tag. Frequency is irrelevant - it is possible to rebalance at distinctive time intervals or when delta exceeds a threshold or many other factors - it continues to be an approximation of continual integral along with your anticipated P&L might be precisely the same.
Vega p/l is by definition the p/l resulting from moves in implied volatility. The next Section of the issue you've answered your self. Brief dated choices have more gamma publicity, very long dated possibilities have additional vega publicity.
$begingroup$ Not sure this is the legitimate question! Gamma p/l is by definition the p/l because of realized volatility currently being unique from implied.
Para que nuestra mente inconsciente pueda “dibujar” un nuevo mapa tiene que actuar con un objetivo claro que responda a la pregunta ¿qué queremos? Y lo complicado es precisamente eso, que en muchas ocasiones no sabemos lo que queremos. Por lo tanto, no sabemos definir nuestro objetivo.

The 2nd term is because of your transform in interest fee. $varepsilon$ is simply what You can not make clear. If almost everything is neat, your $varepsilon$ should not be much too large. You can also see this is incredibly close to a Taylor growth when every little thing is linear, which is why You should utilize your length being an approximation to the 2nd term.
$begingroup$ The data I have found about delta hedging frequency and (gamma) PnL on This page and diverse Many others all reiterate the same point: that the frequency at which you delta-hedge only has an effect on the smoothness and variance of one's PnL.
