When you hedge every single minute, you wouldn't notice the full pnl with the more substantial SD moves but you do seize the full pnl with the smaller sized intraday moves. Conversely, if You merely hedge after per day, you will not realize the entire pnl from the more compact intraday moves (like inside your example) but you would in return know the total pnl with the greater SD moves.
La gente varía mucho a la hora de darse cuenta de lo que ve, escucha o siente. Hay personas que se dedican a observar más su entorno, mientras que otras se fijan más en sus propias emociones y pensamientos.
$begingroup$ When you've got a time series of accumulated/on heading PnL figures, $X_t$, you should be very careful to convert these right into a extra stationary knowledge series of period of time PnL modifications (in all probability day-to-day modifications):
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.
And the incremental PnL of a protracted technique involving $t$ and $t+delta t$ is calculated because the financial gain made by borrowing The cash to purchase the risky belongings at $t$, then offering out your posture at $t+delta t$. So in my example:
Capital is how much that you are investing (inclusive of margin). Your funding expenditures is 49 * Money as that's how much that you are borrowing to have to 50x leverage.

At the conclusion of the day, the EV/Avg(PNL) boils all the way down to iv vs rv of stock. If Those people two are equal, then the EV/PNL would be the very same for each traders in spite of hedging frequency. The sole change will be the variance in their PNL as described earlier mentioned.
Once you then build the portfolio all over again by borrowing $S_ t_1 $ at charge $r$ you are able to realise a PnL at $t_2$ of
