$begingroup$ I am undecided Everything you signify by "cross" results - the sole correlation is that they each are features in the transform in fundamental ($Delta S$)
$begingroup$ If you check out just just one instance, it could seem like the frequency of hedging specifically outcomes the EV/Avg(Pnl), like in the situation you explained in which hedging each minute proved to get extra financially rewarding.
Now, in the above rationalization, we assumed the stock was accomplishing on some frequent vol in any way moments in time. What if the intraday vol diverges considerably through the day-to-day vol? Ie: As an EXAGGERATION, say you have a look at some stock so you work out with the past ten working day closing selling prices that the stock is undertaking over a 1 vol. Basically closes in which it opened each day. You then elect to appear nearer and evaluate vol in thirty minute increments instead of by everyday closing costs. Once you glance intraday/30 min increments, the thing is the stock moves lots, but based upon closing charges performs nonetheless over a one vol.
Nivel Egres: Within the point of view of gamma pnl, The one thing that matters would be the improve inside your asset price. Frequency is irrelevant - you can rebalance at diverse time intervals or when delta exceeds a threshold or all kinds of other items - it remains an approximation of continuous integral along with your anticipated P&L will be exactly the same.
In such a case, whenever we measure vol in smaller sized 30 min increments, we can easily see it is actually substantially various than vol measured on close to close charges. Both equally traders purchase the straddle over a 1 vol for instance, who do you think would be better off? The one who hedges many occasions a day or the one that hedges after at the end of the working day?

As pointed out I never Imagine a single system is a lot more specific, but a method may be needed or suggested by marketplace standards or laws.
Ie: If We all know the inventory will probably shut close to the opening price since it constantly performs with a one vol, and its noon as well as the inventory is down -ten%, we know that it must go higher in the previous couple of several hours of your working day and we could just outright invest in inventory to generate profits.
That's not similar to the pnl equalling the cost paid out, as a substitute the envisioned pnl of your strategy would be similar to the choice benefit. $endgroup$
$begingroup$ If you properly hedge (infinitesimal moves), theta will offset gamma but if you need to do periodic hedges for finite moves, you would've gamma slippage and after that you end up inside of a distribution of Pnl around zero.
Este principio enfatiza la importancia de la flexibilidad. Si una estrategia o enfoque no está dando los resultados deseados, la PNL sugiere probar algo diferente en lugar de persistir en la misma dirección.
Those two PnLs will not coincide. Which 1 do you believe tends to make additional perception? And is there a way to connect the two?
